Common Wood Floor Failures

 

Common Wood Floor Failures

 

By Frederick M. Hueston

 

Natural wood floors add special warmth to a space and can increase the value of a home or business. However, with that said, wood floors are not flawless, and problems can arise that distract from their beauty. Some of these problems can result in long-term damage. All wood floors eventually deteriorate, but if they show signs of deterioration after just a few years, then it is likely that either something went wrong during the installation or that the floor was not properly maintained. This article is a brief guide to some of the most common issues with wood flooring and how to avoid or repair them.

 

Improper Prep Before and During Finish Application

 

Before a finish is placed, the floor must be properly sanded and cleaned to receive the finish. If not, the finish tends to peel. In addition, the finish must be abraded and cleaned in between coats, and adequate drying time allowed before a topcoat is applied. Failure to do any of these things can result in the finish peeling.

 

Improper Wood Floor Sanding

 

Improperly sanded floors have sanding grooves that are problematic to finish application. Wood floor finish settles at the bottom of these sanding grooves, but the tops of the grooves receive little to no finish. Consequently, surface deteriorates when the floor is exposed to foot traffic. To avoid this problem, try sanding bare boards to either 100 or 120 grit, depending on the finish.

 

Pay attention to the sanding materials you use in between coats of finish. Old abrasive screens or sanding pads can cause unattractive scratches that resemble spider webs on a wood floor. Additional finishes can accentuate these flaws. By the time you finish the job, poor sanding will be very obvious. To eliminate these scratches, the finish must be sanded past the coat where the scratches were first produced. Unfortunately, it can be challenging or even impossible to determine which coat of finish is scratched, so your best bet would be to start over and completely refinish the floor.

 

For proper wood floor sanding, sand between each finish application with high-quality abrasive pads that produce smaller, less apparent, and more numerous scratches. A suitable scratch pattern can greatly improve adhesion between finish applications. When sanding oil-based polyurethanes, use 150- to 180-grit pads, and when sanding between applications of water-based finishes, use 220-grit pads.

 

For the best finish, use the best sandpaper.

 

Inadequate Wood Floor Finish Drying Time

If coats of finish are added too quickly, the finish could take up to six months to cure. The result will be a wood floor with an aged appearance. Be sure to allow adequate drying time between finish applications.

 

Improper Wood Floor Maintenance

 

Thoroughly polished and sanded wood floors will need periodic professional services in order to maintain a pristine, welcoming appearance. Damage to the finish can happen in numerous ways. Grit on wood floors behaves like sandpaper with foot traffic. Unprotected furniture feet or unclipped pet nails can severely damage a finish, as well. Sometimes re-coating a slightly worn floor without completely removing the original finish can dramatically improve the appearance of the floor. On the other hand, it is better to sand down a floor to bare wood and refinish it if it has significant wear and severe scratches.

 

Other Common Problems

Other common problems with wood floors include peeling, grit and foreign particles in the finish, finish droplets, stains, gaps, cupping, buckling/sagging, and cracks. Let's take a look at each of them.

 

Peeling

 

The most frequent source of peeling is excess stain that is not removed from the floor before applying finish. Remove excess stain no later than three minutes after it has been applied and allow the floor to completely dry before applying the finish to avoid a buildup of stain residue. Don't use several applications of stain too quickly. Allow it to dry.

 

Other causes of peeling include using finishes that are incompatible with each other or applying finishes to burnished wood, that is, wood that has become too smooth because of high-grit over-sanding.

 

When a floor peels, the best solution is to sand the floor down to the bare wood and start over. The issue might not be resolved by simply abrading the floor and applying a fresh topcoat, because furniture polishes, waxes, and oils used to clean wood floors can soak into the pores of the finish and may hinder new finish from successfully adhering.

 

Grit and Foreign Particles

 

Wet paint functions like a sizable piece of flypaper. Once the finish is complete, any dust or animal hair that gets inside of it will be more noticeable. Clean every surface in the room, including light fixtures and walls, before finishing the floor to keep debris from damaging the finish. Sweep the floor and wipe it down with a tack cloth, but never use tack cloths made for use on automobiles. They can have silicone in them, which jeopardizes the finish.

 

Line your applicator tray with an inside-out garbage bag. Strain the finish before being pouring it into the applicator. Finally, carefully wash and vacuum the applicator to eliminate any remaining loose fibers.

 

In the event that some debris penetrates the finish, make repairs by sanding the floor between applications of finish and then painting the floor with a fresh topcoat.

 

Finish Droplets

 

Moisture is always to blame when tiny polyurethane droplets collect around the borders of each floorboard. The polyurethane that flows into the spaces between the floorboards as the floor moves is what causes the droplets. This issue typically arises when a floor is being finished during the transition between dry and humid seasons. The boards expand as they acclimatize to the weather, pushing any uncured polyurethane out of the gap.

 

Poly droplets can be eliminated with a razor blade, a rag, and floor cleaner if they are discovered in time. If a mess has already been formed, either from walking on the droplets or from allowing them to dry, then each droplet must be manually removed with a razor blade from the floor before the entire surface is abraded in order to prepare for a new topcoat.

 

Stains

 

The most common cause of wood floor stains is pet accidents, although water can also be very destructive. A wood-floor cleanser can typically remove stains that have accumulated on a floor finish, but stains that have penetrated the wood surface must be sanded off. Stains that seep into the wood fibers are the most challenging to remove.

 

Two-part wood bleach can be used to restore the surface of a stained wood floor. Bleach the entire floor, not just a portion of it. (This requires a lot more work but results in a floor with a uniform gloss and hue.) After a couple of hours, neutralize the floor, and once it has dried, it can be sanded and refinished. Deeply soiled floorboards, particularly those that have been affected by pet urine, are typically replaced. However, removing stains with two-part wood bleach can also work.

 

This stain removal method comes with some negative aspects. The tendency of bleach to break down wood fibers can make wood more prone to denting. Additionally, there is no guarantee that the bleach will completely remove the stains from the wood, so wood flooring or floorboards may still need to be replaced.

 

Gaps

 

Wood flooring is susceptible to shifting. Properly installed floorboards will hold tightly together during the humid seasons of the year and may show gaps during the dry seasons. The installation of flooring in overly dry places can also result in abnormal gaps, which are typically caused by the flooring being too moist when it is put in place. Examples include regions that receive a lot of sunlight, floorboards installed directly over heating ducts, and houses heated by wood stoves, which produce a dry indoor environment.

 

Gaps can be an aesthetic problem and should be fixed anytime they detract from the appearance of the entire floor. Fix abnormal gaps during the wettest season of the year when gaps are the smallest. Closing gaps when they are at their widest could result in a floor that buckles due to insufficient space for expansion.

 

Finally, never fill gaps with wood filler. Instead, use wood glue to attach small pieces of wood to the floorboard borders to create a repair. To avoid gluing any boards together, take care to just apply glue to one side of the sliver.

 

Cupping

 

A board's edges cup when the bottom is wetter than the top. The most frequent cause of cupping is the installation of flooring over a damp basement or crawlspace. Although cupping is more likely to occur on wide plank flooring, it can also occur on strip flooring.

 

Vapor retarders can improve the situation by reducing the rate of moisture migration but should not be considered a long-term fix for moisture issues. For strip flooring laid over traditionally constructed floors, use a vapor retarder. On floors over slabs, install broad plank flooring, or install radiant heating.

 

Once moisture problems have been resolved, some cupped floors flatten while others will remain irreversibly distorted. When the moisture content of the top and bottom of the boards is within 1%, a floor that does not lie flat will need to be sanded. To inspect the board bottoms, drill a moisture meter through the subfloor. Do not sand the peaked edges of a floor that has been cupped too soon, or you will risk having crowned boards once the wood is completely dry.

 

Buckling and Sagging

 

Too much moisture can cause wood flooring to expand to the point that it rises off the subfloor, causing shifts to door frames and separation of floor trim from walls. A floor may sag because of a flood, a moist basement, or from being installed when it was too dry. In any event, moisture is the primary cause of buckling and sagging.

 

Proper fastening can help prevent buckling and sagging. Nails should be the right size and spaced correctly. Using the proper size trowel during glue-down installations can help ensure a strong bond between the floors and the subfloor. Poor fastening can make buckling and sagging problems worse.

 

Some buckled floorboards can be refastened, but some need to be taken out. When feasible, reuse floorboards, but if the tongues and grooves are broken or the boards are damaged, you must replace them. Do not attempt to restore buckled flooring until moisture problems have been resolved and the moisture content of the floorboards and subfloor is at the proper level.

 

Cracks

 

Compared to other types of flooring, factory-finished wood floors have more cracks, and a wood flooring nailer can easily ruin the finish on these boards. Most manufacturers produce adapters for their nailers that prevent the force of the nailer from concentrating on the surface of the floorboards.

 

Boards with a severely damaged edges should be immediately replaced during installation.

 

The faces of floorboards, whether factory-finished or normal, can develop cracks. Checks in the wood are usually to blame for this damage. Some species of wood are more prone checking and cracking than others.

 

Manufacturers can also cause cracking if the kiln dries the wood too soon. A manufacturer repair kit, which normally consists of wood filler, colored marker, and a bottle of finish, can be used to fix factory-finished boards.  To ensure that the colors, tones, and sheen are exactly matched, replace the board, or fix the crack with wood filler before applying a layer of finish to the entire floor.

 

Follow these suggestions to resolve problems that diminish the beauty of wood floors or cause long-term damage. A properly installed and maintained wood floor can last a lifetime.

Does Terrazzo Contain Asbestos and is it dangerous to restore or maintain?

 

Does Terrazzo Contain Asbestos and is it dangerous to restore or maintain?

By Frederick M. Hueston, Stone Forensics

 

There are millions of square feet of terrazzo floors throughout the US and the world. I have had several calls in recent year from terrazzo refinishing contractors that are concerned with asbestos exposure when working with terrazzo. The following explains the dangers as well as how to safely restore and maintain terrazzo

Asbestos Exposure

First lets take a look at what asbestos is and how one becomes exposed.

When asbestos fibers as small as a human hair become airborne, asbestos exposure occurs. The hazardous mineral dust can linger in the air for hours, posing a risk to anyone nearby who breathes it in or consumes it.

Asbestos fibers may take 48 to 72 hours to settle in a setting with few disturbances. The dust is so light that if it is disturbed, it can readily become airborne once more.

Asbestos exposure in Terrazzo

Terrazzo that was poured before the 1980’s may contain asbestos and for this reason it is recommended that it be tested for asbestos before any abrasives are used on it.  Even though the abrasives are used wet it can still produce asbestos fibers in the air. It is still possible to grind and hone asbestos containing terrazzo but will require the services of an asbestos abatement company. This will involve workers wearing fully equipped hazmat suits and will also require the area to be sealed off as well as the use of HEPA filter vacuums etc.

Maintenance of Asbestos Containing Terrazzo

Maintaining a terrazzo floor that contains asbestos is another story and as long as no abrasives are used, maintenance is simple and won’t expose you or anyone to these harmful fibers.  If a floor finish is used it serves to contain the asbestos, however the current trend in terrazzo refinishing is to place a highly reflective shine on the floor though diamond abrasives. If this is the case than asbestos abatement practices will be necessary.  Once the terrazzo is polished or a coating is placed on it the following maintenance program will be applicable:

Daily Maintenance

The three most important tasks that can be done on a daily basis to keep the terrazzo looking new and extending the time before restoration is required are: Dust Mop, Dust Mop and Dust Mop.  The most destructive material to most terrazzo is sand, dirt and miscellaneous grit.  If these substances could be eliminated, maintenance of the terrazzo would be almost non-existent.  A terrazzo floor can never be dust mopped too often.  Use a clean, non-treated, dry dust mop at least two to three times a day in high traffic areas and less often in low traffic areas.  Walk off mats placed outside and inside an entrance will also eliminate a good portion of sand, dirt and grit.  It takes approximately seven steps to remove all loose dirt from the bottom of ones shoes. Walk off mats also need to be removed and cleaned daily. Keep this in mind when purchasing walk off mats.  Remember if sand, dirt and grit are eliminated there will be nothing left behind to scratch and dull the terrazzo. This will also keep any abrasive grit from releasing asbestos into the air.

                                                   

Cleaning

All terrazzo, both polished and unpolished should be cleaned daily in high traffic areas and less often in lower traffic areas.  A clean rayon or cotton string mop should be used with cold to warm water with the addition of a quality Green Approved neutral cleaner or stone soap. Approved Green Neutral cleaners are defined as surfactant type detergents that have a Ph of 7.  Acidic and alkaline cleaners should not be used.  Be sure to follow the directions very carefully. 

If the area is large an auto scrubber can also be used with the same neutral cleaner and a soft brush or pad.

 

Maintaining Terrazzo that contains asbestos is simple and top rule to follow is to avoid any abrasives.

Will Robots Replace People in Stone and Tile Trades?

 

Will Robots Replace People in Stone and Tile Trades?


Most people are familiar with the Jetsons, a cartoon featuring 20th century futurism, and how almost everything in the show was automated, from coffee makers to self-driving, flying cars. Today, real-life advances in technology are eerily reminiscent of the world of the Jetsons. We've got voice-activated appliances, computer-controlled robots pack and move goods, writing robots are generating stories that used to be written by journalists, and autonomous drones have been replacing humans in the military and in the distribution sector. Robots have replaced chefs, surgeons, postal workers, and many other jobs. Will stone and tile setters, restoration contractors, and fabricators eventually be replaced with automation and robots? Some of this automation is already here. Let's take a look at the latest automated technologies in the stone and tile industry and have a little fun speculating about what might come next.

Stone Countertop Fabrication

Many fabricator shops are already fully automated. With advancements in CNC technology, many saw operators and polishers have been replaced. Material handling, such as loading of slabs, can be accomplished with automation. Even extracting the stone from the quarry can be automated. Although this automation replaces skilled fabricators, it also creates opportunities for other jobs, such as computer programmers.

Stone Restoration

If you think that it would be difficult to replace stone floor technicians who clean or polish floors with robots, then you may be stuck in the stone age. There are now programable floor machines and auto scrubbers that can operate without an operator. 

As of yet, there are still some tasks that cannot be performed by robots, such as making judgment calls about selecting the most appropriate products, tools, and methods. Performing delicate or highly customized restoration work may always require the precision of a craftsperson. Who knows what the future holds?

Stone and Tile Setters
One might think that tile setters could never be replaced. How could a robot ever install a bathroom shower, which requires detailed waterproofing and tile setting knowledge and skills? In recent years, companies have developed some amazing technologies. For example, SurePods(surepods.com) manufacturers complete bathroom pods that include a sink, vanity, shower, and toilet all in one unit manufactured with CNC machines. Each unit is lifted into a building, then the plumbing and electrical are hooked up, and BADA-BING, it's ready for use.

Stone Carvers

Can automation replace art? It sure can. CNC machines are already being programed to carve stone to the exact copy of famous sculptures, such as the Venus De Milo. Also large, 3D printers are already widely used. They are even capable of building a home.

Future generations will see more and more automation being introduced to the stone and tile industry. A study by Midwest Economic Policy Institute (MEPI) estimates that by 2057, robots could replace or displace 2.7 million jobs in construction. There is no need to hang up your trowel or put away your floor machine just yet, but you have been warned. The Jetsons era has arrived.

Is Natural Stone the Right Choice for your Home

 

Is Natural Stone the Right Choice for your Home

By Frederick M. Hueston, stoneforensics.com

 

This last year has seen a large increase in the number of people having natural stone, marble, granite, limestone, sandstone or slate fitted into their homes either as work surfaces or as flooring. No man-made product can rival the beauty of well-presented natural stone with its myriad of colors and patterns which are unique to your individual stone.

With this increased interest in returning to natural stone products has come an avalanche of products to clean, shine and seal the stones. Importers, tile retailers, builders and chemical firms have all jumped on the band wagon and see big profits in natural stone. Unfortunately, it would seem that very few of these companies have any understanding of the products they are selling or fitting or advising customers to purchase.

In the past most of my calls was concerned with restoring old marble, granite or limestone but increasingly I am getting called out to deal with brand new tiles which have developed problems.

Some of these problems are;

Tiles being laid so that there is significant lippage between them
Grouting gaps being too large
Tiles smeared with grout after sealing
Incorrect sealant being used
Acrylic sealants being applied
Polish or wax being applied to the surface
Marble and limestone being used in kitchens
Slate being used in showers
Not sealing the stone
Applying a seal and then assuming that it is now protected from all possible sources of damage
Discoloration of the tiles because sealant is left on the surface
Use of acidic cleaners in the builders clean
Poor or non existent care and maintenance programs provided to the client

How do you ensure you are not left with a big bill after the builders have moved out?

Buy your tiles from a supplier that provides good advice and has an installation service,
Research the topic prior to purchase so that you can ask pertinent questions. If you get suspect or glib answers walk away and shop elsewhere
Do not simply go for the cheapest, they may prove to more expensive in the long run
If possible retain some of the money until the job is completed to your satisfaction. That way if there is a problem you can insist on it being rectified.

Your biggest protection is to get acquainted with the properties of natural stone and its care and maintenance before setting out to purchase your preferred stone type. You can do this by carrying out the appropriate search on the Web.

Slate tile flooring dos and don’ts

 

Slate tile flooring dos and don’ts

By Frederick M. Hueston, stoneforensics.com

 

Slate tile flooring is available in a wide variety of colors. You can choose from green, pink, blue and yellow shades. You may also go for natural surface textures of slate tile flooring and these textures come in different variety. The flooring is slip-resistant and hence makes a premium choice for most people across the globe.

Slate tile flooring is ideal for residential and commercial interiors and exteriors. It is easy to install and available with decorative color variation and slip-resistance quality.

Here are some do’s and don’ts you need to keep in mind with slate tile flooring.

Do’s:

a)         You should be sure of the fact that area in which you desire to install your slate tile flooring is apt for the climate, foot traffic and other important factors. A sales representative will be able to help you in this matter.

b)         It is very important to consider the substrate over which you wish to install the slate tiles. The tile should suit your requirements. You should always ask your sales representative about the suitability of your substrate with respect to the slate tile product you wish to purchase.

c)         You must expect color variations when it comes to slate tile flooring and utilize them to your advantage.

d)         It is necessary to keep yourself informed with the warranty details. Try to read all the instructions or information related to the slate tile flooring purchase.

e)         Before making a purchase, test the color patterns, thickness variation and overall spacing of the slate you choose via laying out the slate in a dry run.

f)         You require using a special type of mortar for slate tile. The mortar should be compatible to your interior and exterior installation. Try taking expert advice from sales representative about some brands and varieties of mortar available on the market. You should never forget to read the instructions available on the products you plan to purchase.

g)         Slate tile flooring sealant is very important. You can choose from several varieties available such a high-gloss sealant that provides the tile a lustrous look, low sheen that is reflective and no sheen that provides slate a natural look.

h)         You should look forward to consult an experienced flooring professional in case, you don’t have any experience in laying slate tile all by yourself. This will also help you stay miles away from mistakes that may make your wallet lighter.

 

Don’ts:

a)         Never ever forget to allow for breakage and waste while placing your order. Remember that accidents can happen anytime.

b)         You should not fail to supervise your substrate for dirt or loose materials. A clear, clean and level substrate is very important for a perfect slate tile flooring installation.

c)         Don’t install slate tile flooring on a wet surface. The moisture trapped on the surface may make installation difficult for you.

d)         Don’t apply a sealer to a slate tile floor that has been oiled or waxed and not cured. The marks can prove to be very difficult to remove later.

e)         Grouting soon is not a good idea. Always allow the mortar to properly set.

Care and Maintenance for Butcher Block Countertops

 

Care and Maintenance for Butcher Block Countertops

By Frederick M. Hueston, stoneforensics.com

 

 Butcher block wood is widely considered the healthiest building material in the world. The solid wood represents a reliable, sturdy material that can last very long without requiring excessive protection. However, Butcher Block is a natural living material and, unlike man-made materials, it reacts to different environments in specific ways. We would like to draw your attention to the basic maintenance instructions for Butcher Block countertops. Following these directions will result in having a great looking, easy to maintain custom countertop that will last for many years.

Tops with a Mineral Oil Finish

The countertop must be oiled carefully on top, bottom and sides, giving a special attention to the end-grain area, as the section that the wood is most likely to absorb humidity through. Each cut or drill you make in the countertop (either for size adjustment, sink cutout or other purposes) must also be oiled thoroughly. Proterra mineral oil (Hesse, Germany) is a product that we recommend for kitchen tops applications given that it was specially designed to come in contact with foods. For situations where there is a great deal of humidity involved (like sinks, water faucets, etc) the mineral oil only will not assure the best protection and it is advisable to use polyurethane or any other similar finishing instead.

With a soft brush, oil the wood generously on all sides or simply pour a small quantity of oil on the wood and then spread it with the brush. Let the wood soak the oil for about 20-30 minutes and then remove the excess with an absorbent paper towel. When the top is first installed, it is advisable to apply 2-3 successive coats of oil, after which, the oil can be applied once several months or whenever needed. Every time you sand the area to remove scratches or cut marks, a new coat of oil must applied.

Maintenance

In order to keep your top clean, periodically scrape or brush away any food residues existing on its surface, wash with warm soapy water and dry it well using either a dry cloth or paper towels. Apply a new coat of oil any time needed. Alternatively, you can warm up a 1:4 combination of beeswax and mineral oil until the mixture becomes homogenized and then apply it uniformly on top’s surface, thus getting supplementary protection against both stains and humidity.

Avoid setting your butcher block next to extreme heat sources like stoves unless there is appropriate insulation between the heat source and the top. Avoid spilling vinegar on a wood top having a mineral oil finishing, as it can cause cupping or cracking. Do not use corrosive chemicals or excessively harsh detergents on a wooden top having a mineral oil finishing, as they can cause irreversible depreciation.

 

 

Repairing

If properly installed and sealed and periodically oiled, there is no reason that your top won’t last a long period of time in the same good shape it was when new. Sometimes however, due to poor maintenance and improper environmental conditions, some problems might arise; it is our duty, therefore to inform about these problems and the way to solve them.

·           Cupping and warping

Are prone to appear whenever there is a significant difference of moisture between the topside and the bottom side of the panel. If possible, place the top on a flat, hard surface, concave side facing down. On the convex side, uniformly place some fairly heavy objects. It will take up to 12 hours until the panel will straighten completely, after which, oil it abundantly on all sides.

If it is not possible to manipulate the top, simply apply generously mineral oil on the concave side until the panels straightens. In this case, however, you might need to repeat this operation several times to obtain the desired result.

·           End splits

Will manifest whenever the panel is placed in an excessive dry environment without being properly sealed. To repair, mix wood sand with a small amount of water-based wood glue and fill the cracks thoroughly. Allow 15-20 minutes to cure, sand the area with a 120 grit sand paper and then oil the top freely.

·           Scratches, cut marks and food stains

Can be removed by sanding uniformly the affected area, brushing away the resulting wood dust and applying a new coat of mineral oil. The finger-jointed panels can be sanded to a 3/8” depth, while for the continuous lamella panels and the end-grain butcher blocks, there are no such restrictions.

Tops with a Polyurethane Finishing

A solid wood surface finished with polyurethane based finishing requires no maintenance at all. However, scratches, cut marks and other damages will be difficult to repair; therefore extra care is required.

Cleaning Granite Countertops

 

Cleaning Granite Countertops

By Frederick M. Hueston, Stoneforensics.com

 

Homeowners who are seeking to increase value to their homes enjoy the durability and easy maintenance when upgrading to granite countertops. Granite is the most durable of all stones, second only to diamonds. Granite, being created from molten rock, can withstand the heat from a hot pot without a trivet. The hardness of the surface is excellent for handling dough and confectionery. While durable and low maintenance, however, they are not impervious to damage.

Properly installed granite countertops should last a lifetime, one justification for the higher costs associated with the material and installation. The granite suppler should provide personalized instructions for care with each slab, since all granite is made up of many different minerals. Even if two different stone slabs come from the same part of the world, there will be variances in the granite that require different kinds of attention.

Proper care ensures the longevity and beauty expected from this premium product. In addition to the polished finish, it's possible to get a “honed” or flat finish. Although a honed finish can be very attractive, it is not recommended for kitchen use. Over time, everyday use will tend to lend a polish to some areas, and the additional necessary sealers will distract from the beauty of the surface. A polished finish is easiest to maintain with regular care that includes proper cleaning and the use of sealers to prevent staining.

Care for a polished finish begins with daily attention to what is placed on the surface. Granite countertops are hard and can withstand a falling can of soup, but the polished surface is a bit more delicate. Never use the granite as a cutting surface, always use a cutting board. Avoid allowing acidic foods such as lemon juice, vinegar and soft drinks to be left on the surface for any amount of time, as they can etch the surface. Another thing that removes the polished shine are harsh cleaning products or abrasive cleansers (liquid or powder). To clean the surface without leaving streaks, use only a small amount of warm water with a ph balanced dishwashing liquid or a neutral stone cleaner.

Although granite is extremely hard, some of the minerals in it may be very soft. The existence of different minerals is what makes the granite easy to scratch, be chipped or break along the grain. In order to protect the surface, it is recommended to avoid dragging pots, pans or appliances across the stone. Scooting something across the countertop that has even a grain of sugar under it can scratch the polished surface.

Once a year, a penetrating sealant should be applied.  Regular polishing will keep the finish gleaming. Use a penetrating sealant recommended by the supplier or the home builder. Avoid using a stone sealer that will not penetrate the stone, as it will create a cloudy surface that will have to be removed by stripping the entire countertop, using harsh solvents. Remember, the glossy shine isn't caused by a coating on the surface, but by expert polishing using diamond polishing tools.

 

If there is minor damage to a granite countertop, it can be resolved by the homeowner. If a pot or pan leaves a grey or black mark on the surface, it can be polished out using fine steel wool. If a glue-like substance is stuck on the countertop, it is possible to scrape it off with a credit card or single sided razor blade. Small marks made during the removal can be polished out with a fine steel wool. If the granite is chipped or cracked, a professional should be called in to perform invisible repairs.

In addition to its strength, granite is a very beautiful stone that adds color and warmth to any kitchen. With just a little care to protect their beauty and utility, granite countertops will last a lifetime.
