Includes slate derived from shale, quartz-based stone from quartzitic sand, and true marble from limestone. One of the hardest minerals that compose stones such as sandstone, granite, and quartzite. A radius can be applied to a countertop edge profile or to moderate an exposed countertop outside corner. The resin fills any voids in the face of the stone giving the surface a smoother, nearly flawless finish.An elastic adhesive compound used to seal stone veneer joints.

A chemical treatment applied to the face of stone used as a protectant to retard staining. Characterized by an excellent parallel cleavage, and entirely independent of original bedding, slate may be split easily into relatively thin slabs.

Some varieties of travertine take a polish and are known commercially as marble. Not all commercial granites are true geologic granites.

In the commercial realm, “granite” gets classified as a hard natural stone which can be polished and requires more aggressive tools and abrasive than what would be used on marble.

This is a pretty broad and not very scientific kind of description, which leaves some really wide wiggle room. It has been used as cladding for buildings and for monuments and gravestones for many, many years, though. What makes the commercial “granites” so appealing is the fact they are so diverse. There are virtually hundreds of different colors and patterns.

Testing for absorption issues on granite samples would be as easy as dripping some water on your sample and letting it sit for a while. If it darkens the stone a little, a sealer might help. If the stone immediately becomes darker and maintains the dark spot for some time, stay away! Etching is another “must-do” test for stones to be used in a kitchen. Etches will show up as dull spots on an otherwise shiny surface. Sealers will not prevent etches because etches are chemical reactions and have nothing to do with the absorption rate of the stone in question. There are two ways to work around this issue. One is to avoid the stone that etched in testing and the other is to hone and enhance the stone. To test for etching, place a wedge of lemon or lime, cut side down, on the sample overnight. Wipe the sample in the morning and hold it at an angle to the light. If there is a rough looking spot where the shine is absent, you have etched the stone. Etching will normally occur where calcium or calcite is present in the make-up of the stone. The last item to consider is resinated slabs.

Resining is a process where resins get impregnated into the stone slabs before they are finished. The remaining surface resin is removed through the polishing process, leaving the resin in the pits and fissures.

Even though it is quite an absorbent material, once it is resined, may not require the application of a sealer) 3. This provides a smooth finish to the polished slabs) 4. Another side effect of the resining process is enhanced colors.

The geologic classification has virtually no impact on the performance of the material in a kitchen. Others are practically impervious to stains and only slightly softer than diamond.


True Granite ≫ The Fabricator Network

A good fabricator will make certain you understand the material properties of the stone you selected. Many stones are treated in the polishing process with a resin which is applied before polishing. The resin treatment process also makes the stone much more stain resistant. The fabricator has to treat the edges during the finishing process so the edge color matches the top. A good fabricator will make sure you know there is fill and where it will be in your countertops as it could easily be much more conspicious in your countertop than as part of the slab. Many stones used in countertops are very stain resistant. Others, like the various limestones and marble colors, are very easily stained even when properly sealed. These stone are so porous and hydrophillic that when placed on a wet saw table the top of the stone will start showing wet spots from water wicked up thru the stone after only a few minutes.

Also, some stones can be rock pitched easily and on others it’s almost impossible. If a fabricator calls you and says a particular edge isn’t working on your stone it’snot because he doesn’t want to do it; it’s because the stone won’t let him. Which granite stones are harder and less porous in general if they are quality? It’s so hard as a consumer to know if you are getting something that will work well for you in your kitchen. Can you speak a little about different kinds of sealers and how effective they are? What is your experience with different sealers? Class 5 granites are the hardest although most actual granites are planty hard enough to be durable. Soibean; generally there are normal and “porous plus” type sealers.

In my experience the solvent based sealers are more effective. More often than not if a stone is stained the stain can be removed with a poultice application using the correct solvent for the stain. Anyway, do you see anything wrong with us giving it another seal treatment now?

At least around here, the class or grade the stoneyard gives to a slab has nothing whatsoever to do with its quality or hardnessabsorption rate. I have spoken with my fabricator who said he would try to hone the island as it is the worst. There are no fissures but there are some fill places that are about the size of a pencil eraser. Is there anything that can be done now to the stone? In summary, is there a product to smooth out a stone after the installation? The stone will be a little glossier when done but your shedding problem should be gone. The supplier granite yard is out of business and the fabricator although it was one of their suppliers says there is nothing they can do about it. It snags my dish cloth and the sink recently cracked and has to be replaced. The sink is a mystery as to why that happened. The island is the worst thank goodness since we could just replace that to keep down the cost. I really wasn’t planning on an expense like this coming up this soon!Both brands are available on-line and most fab shops carry sealer in consumer size containers.

Some sealers include an “enhancer” which helps bring out the color in honed stone. Most granites don’t even need it that often but it will never hurt to do it too often. If you have existing stone and don’t know what sealer (if any) is on there you can strip it with acetone (which won’t hurt the stone) and then reseal. A flamed finish is very coarse used primarily for stair treads or other flooring applications.

In many areas you can get a honed or other finish on a polished slab for an upcharge.

Watch out here is that removing the polish “washes out” the color so you need to be certain you want the finish as it is a non-refundable special order when done as a treatment to a polished slab. Some slab suppliers deliberately create their own name for stones to limit the ability of the consumer to compare pricing. Somewhat chippy for the fabricator which imposes some limitations on suitable edge profiles.

Some stones are quarried at the point of origin and then shipped as blocks to another country for processing into slabs.

This could result in differeent “origins” for the same stone as one supplier might do the slab processing local to the quarry and another could be in a different country. I would still seal any granite that hasn’t been resined. Sealant will actually mar those stones’ appearance with streaks, hazing, and film until the sealer is removed. Sealers only protect stone from staining through absorption, so in stones with low absorption co-efficients, sealing would be superfluous.

We did a trial run with granite in our master bath to see how we like it. I really wanted the black granite in the kitchen, but having it in the master bath has shown me that a dark countertop might be too high maintenance. I just wish that names were more standardized, so that you could be more sure of what you’re getting when you go look at the stone yards.

I stand by my assertion that it’s ok to seal any granite. We did once have some black that had smeary streaks but it was traced to the stone itself which had been dyed inconsistently.I thought to look at some of the remnants from the job and was able to prove the smears were in the stone itself as the remnants had never been sealed. We can’t leave anything with any kind of acidity on it without a gray ring forming. We are trying to resolve the issue with the fabricator, but their solution is to remove existing sealer and re-seal. I think it’s the sealer that’s etching, and we would be better off without one. They types of liquids that are producing the rings are white grape juice, ice tea with lemon, and of course, red wine. It’s normally a problem limited to stones with calcium carbonate like marble and limestone although the acid in household rust remover products can etch many granites.

I would strip the tops with acetone and then use a different sealer. The company is scheduled to come over tomorrow. Because we can only find granite 124 inches not anything longer and really didn’t want a seam. If the granite has more of an all-over pattern, then a good, tight, neat seam isn’t that visible anyway. They did not seal the granite when it was installed, but for our bathroom we bought a pre-fab counter to save money. We just went and looked at the slabs the other day. The 15 year sealer isn’t a bad product but it a load of bull in a pretty marketed package. Alcohol is used on granite counters for people who want alcohol’s antibacterial properties, not to remove spots.

I read on a stone website that f you buy a commercial granite cleaner, it might contain alcohol at 5% at most. So, you may have made your counter worse if you used a lot of alcohol. Anyway, it could be that the spots on your bathroom counter are etching caused by toothpaste and/or mouthwash. I have some etching in my kids’ bathroom caused by acne medications.

And my final point is that sealer is to prevent staining.

Is granite tiles cheaper than using a granite slab? While not all granites have the same physical characteristics, most granites have naturally low moisture absorption rates.

Therefore, staining of your granite top, especially when highly polished, is normally not an issue. With that, few materials have the ability to scratch your granite. Therefore, one can rest assured that granite will not scratch under normal conditions.

While one of the most aesthetically pleasing stones, granite is also one of the hardest. Unless you are heavily abusing your countertop with a hammer or another excessive force, granite is unlikely to chip. Are granite countertops easy to care for? Simply wipe your countertops down with mild soap and water mix or an ammonia-free window cleaner to keep them looking new for years to come. Blot the spill with a paper towel immediately. Do not wipe the area, it will only spread the spill. How does granite compare with synthetic countertops in the long run? Countertops made from acrylic and other manufactured materials may have the “look” of granite, but the similarities end there. Some marbles with honed or matte finishes also make high quality kitchen countertops.

Granite is an excellent choice for kitchen countertops, floors, tabletops, and other heavily used surfaces.

While some synthetic surfaces scratch easily and melt under hot cookware, granite resists heat. Limestone is widely used as a building stone because it is readily available and easy to handle. Sandstone and slate are often used for exterior paving stones, or pavers.

The term “natural stone” refers to a variety of mountain-born mineral substances that stand in contrast to any synthetic or manufactured stone products . It’s important to understand the characteristics of the type of stone flooring tile you are purchasing in order to determine whether it is appropriate for a specific location. As you shop for natural stone tiles, these are a number of general factors that you should consider. The more absorbent it is, the more susceptible the stone will be to stain. Absorbent stone can also be prone to cracking damage if it is subjected to freezing conditions.

Natural stones vary greatly in their absorption rates, with sandstone being the most porous and granite the most impervious to water absorption. They are often used in high-traffic commercial applications.This can refer to the size, shape, and thickness of the tile, as well as the condition of its surface. Grade 2 consists of materials with minor defects, such as chips, scratches, or irregular surfaces.

The higher the coefficient, the more traction a tile will have. This number is especially important in moist environments such as bathrooms and kitchens, as well as high-traffic commercial areas.

Many of the factors above will determine whether a material should be used in an open air environment. Non-vitreous materials will be subject to staining through dirt and acid rain, as well as cracking when absorbed materials freeze and expand. Sometimes iron is present in these materials, which can manifest as bright red and amber hues in the surface of the stone. The problem in an outdoor environment is that those traces of iron can oxidize, a process more commonly known as rusting. Purchasing stones which were acquired locally can cut down on the environmental impact of transport. Some polished materials such as marble can scratch easily. Some stones are very brittle and will chip easily. Find out whether it is appropriate for your specific application and how much maintenance it will require.


Granite Questions Often Asked

Each natural stone has unique characteristics and maintenance requirements.

It depends on your lifestyle and the application of the material, as some types of stone may be more suitable than others.

It is always possible to scratch a surface, even a diamond, if it is subjected to sufficient force. However, granite is an extremely hard surface and will not scratch under normal use. Why is one particular color of granite more expensive than another? The price of granite is based on its availability – the lesser the supply the higher the cost. The color, availability and movement of the stone determine the price. Are stones from certain countries considered better than others? Natural stone is produced by nature the same way regardless of geographic origin. The finishing and manufacturing process reveals the remarkable beauty of natural stone. Is it better to get a lighter color than a darker color? The color and shade is strictly a matter of taste and what best suits your lifestyle. Dark and light colors are comparable in quality. As quarry and manufacturing technologies improve, the cost of natural stone has become more affordable and is comparable to other solid surface materials.

Marble and granite, in particular, have reduced in price in recent years.

Natural stone is more durable; therefore, it is a better value in the long term. The price of stone depends on the capacity of the quarry and its production volume. The higher the production, the less expensive the price. Natural stone dramatically transforms any room or outdoor space. Its natural beauty and durability make it an excellent investment.Natural stone can be cut-to-size for almost any space inside or outside your home. About 90% of all our granites are resin treated at the quarry. As added protection from staining, the granite surface should be sealed. Most stains that do occur in granite can be removed. Please check with your industry professional for more information. You should never have a problem with chipping or cracking under normal kitchen conditions.

You should not drop very heavy, hard objects onto your countertop, and although it may seem obvious, you shouldn’t stand on granite countertops either.The natural stone industry standard is a seam width of 1/16 of an inch. There is a maximum lippage (amount one piece will protrude above another) for the industry of 3/32 of an inch at the center point of the countertop with no lippage at the ends.

Granite is formed by extreme heat and pressure combined beneath the earth’s crust. It cannot be affected by heat from a cook top or frying pan. A lit flame placed under the granite will have no melting effect and will not leave any burned or scarred marks.

Although it can be sealed, marble is much more porous than granite making it susceptible to staining in heavy use areas such as kitchens.


Facts About Granite Slab Quality Variables

Marble also is much softer than granite increasing the likelihood of scratching and chipping under frequent use. Further, the mineral composition of marble can react with certain acidic products like citrus juice and vinegar causing the polished finish to etch. Bacteria requires several things in order to thrive and grow: oxygen, sunlight, water, nutrients and a substrate to form on. As a result, granite is not a habitable environment for bacteria to live and grow. Granite ranked first in cleanability and was second only to stainless steel in inhibiting bacteria growth. Mont porcelain has color consistency that is thru the body not just on the surface. Because porcelain can withstand high levels of heat, it is a valuable choice for countertops and fireplaces.

Maintenance is simple with mild detergent and clean water. Yes and can easily be cleaned with a mild cleanser and damp cloth or sponge. Can porcelain be used in an exterior application? Mont porcelain surfaces are rated frost-proof and can be used in exterior applications.

What is the difference between glazed and full-body porcelain surfaces? Mont full-body porcelain does not show wear because its color is absorbed through the screening process, making it ideal for commercial applications unlike other glazed surfaces which are coated with a liquid glass and then baked into just the surface of the clay. Mont features color-body porcelain meaning the color is absorbed through the screening process.

A concrete board underlayment should be installed over your wood sub floor prior to the porcelain installation. This will provide the rigidity needed to minimize floor movement so your installation remains stable. Does using a larger porcelain piece make a room appear larger? Using large, porcelain pieces gives any size room a larger feel. What’s the difference between ceramic and porcelain? Mont porcelain is made from porcelain clay and fired at a very high temperature, which makes the material stronger and more chip resistant than ceramic. What is the best tile for exterior applications? Mont’s through-body porcelain tile is best for outdoor applications.

Our porcelain is pressed under higher pressure and fired at higher temperatures than ceramic. A large format porcelain slab is 118 inches long by 59 inches high and only ¼ inch in thickness.
