They are chosen by professional contractors for sealing granite, marble, and slate countertops. It also resists the penetration of oil, the liquid that most easily stains natural stone countertops. When completely dry, use another clean, dry cloth to apply the sealer. Wet the cloth with impregnating sealer, and wipe the sealer onto the surface of the counter.

Make sure the entire surface including edges and backsplashes are wet but not soaked. When the second coat is dry, your stone countertop sealing job is complete. When properly sealed with an impregnating product, the surface of your slate, granite or marble countertops will repel moisture and oil, virtually eliminating the risk of stains.

Allow the first coat to dry for five to ten minutes, and apply a second coat. The full repellant effect is achieved within 24 hours, so wait a day before preparing food on the countertop. However, it still makes sense to dry spills on the countertop and clean oil from them promptly. The results will be the lasting beauty and durability of your stone counters in the years ahead.

Serious Problems With Granite Countertops That Cannot Be by decordezine.com

Granite countertops have to be sealed on a yearly basis to maintain their shine and luster. Kitchen sinks have to be carefully purchased, because replacing the sink installed in-between the granite countertop will prove expensive, as it will require the removal of the entire granite slab. The expensive granite you invested in, can lose its sparkle and shine. If the surface is not sealed regularly, it may become more susceptible to stains. You can either seal the granite countertop on your own or seek professional assistance. This allegation has been mostly made by competing countertop material distributors. It is also believed that not every type of granite is harmful, thus, worried homeowners can get their homes tested for radon gas, with do-it-yourself radon test kits to check if they are living in high levels of radon. This is because the hard granite stones comprises some soft, thin strips of granite, which cannot absorb all the heat applied to its surface. Once installed, granite is difficult to remove and on removal, will damage the kitchen cabinets; thus, replacing them would mean remodeling the kitchen. It does have its disadvantages, however, mostly all products in the market have some or the other drawback.

Despite these cons, granite countertops are elegant, unique and enhance the beauty of one’s kitchen.

Nonetheless, like every raw material, it has its share of drawbacks as well. Its heat-resistant and scratch-resistant qualities make it an ideal choice for kitchen countertops. It comes in various colors and styles and its speckled, salt and peppered appearance enhances the beauty of the kitchen.

Its installation requires new cabinetry to be placed as a part of the entire kitchen makeover. Neglecting sealing on a regular basis can cause the granite countertop to become cloudy and stained. As far as possible, to minimize the damage, clean spills right away. Granite needs to be maintained on a yearly basis, which means the surface needs to be sealed every 12 to 14 months. Besides, stains and bacteria can find their way into the crevices of the granite surface. This sealing has to be done before staining has occurred, or else the stain will remain for life. However, it’s important to carry out sealing regularly or else the stone will get ruined.

Radon gas is a radioactive element and is a leading cause for lung cancer. However, the safe level of radon exposure is not yet known to man; neglecting this fact is quite difficult. Thus, one must be careful to place hot dishes on trivets and hot pads.

This is because these common household cleaning agents contain acids, alkalies and other chemicals, which can harm the granite. If you get bored of the color or pattern of the granite over the years, you cannot replace the granite easily. While deciding on which countertop material to buy, one must weigh the pros and cons.

Sealing Removing Stains From Granite Countertops by thespruce.com

Sealing your granite is one of the many things you just need to put up with if you want to own this type of countertop. Keep in mind, the price is really not much of an issue as this stuff goes a long way. But certainly seal before the water gets on your counters, and especially before any kind of stains occurs.

People buy granite countertops more for natural beauty than for pure practicality (in fact, granite is also susceptible to scorching from hot pans). Just a few squirts are usually enough to fully coat an average-sized bathroom counter.

If you don’t get it on right away, it’s not like your granite is permanently damaged for life. Out of desperation to cure the problem we stumbled on to this guy and his stain remover worked!

How To Seal Your Granite Or Marble Countertops: by archcitygranite.com

Obviously, all the daily used objects should be removed from your countertops before you start cleaning. If you find some debris, you can clean with a mild soap and warm water and then wipe off again with a clean, dry cloth. Be generous while spraying and make sure you have a good layer of liquid on the countertops.

Depending on the type of stone, you may find some hazy spots after you wipe off the excess liquid.

In strict sense stone sealers are stain repellents rather than sealers.

Feel the countertops with your hand to feel if any food or debris is still present on the countertop. Wear kitchen gloves and spray the stone sealer on the surface of the granite. This is to make sure there is enough liquid to penetrate the naturally occurring pores in the granite. Wait about 15 minutes and then wipe off the excess liquid from the countertops with a clean, dry cloth.

If this happens pour a very small amount of sealant on a clean cloth and wipe off the hazy spots. Stone sealer is a misnomer because the sealer is actually an ‘ impregnator ‘ that penetrates the pores of the stone surface rather than sealing the pores.

A properly sealed countertop will cause liquids to bead on the surface. Pizza grease can be a culprit, too, when it soaks through the bottom of the pizza box and onto the countertop. Keep in mind that different pieces of granite have different porosities. To determine if it’s time to reseal a countertop, dribble some water onto the countertop. Before making the decision about granite countertops, it’s important to know the benefits and costs. Can you guess what material is the most popular for creating an everlasting on a headstone?

In small areas where the faucets, sinks and stovetops lie, you should apply sealer after the countertop is installed. Generally, you should seal most kitchen granite countertops annually. Some countertop areas may need to be sealed more often than others.

When sealing, work in small areas, allowing the sealer to absorb for the recommended amount of time before applying the second application. Read on to learn about the pros and cons of granite countertops. Granite countertops are so durable they can literally outlast the building in which they reside.

However, these chemical compounds contain much larger molecules that do not penetrate as deeply or bond as well. These molecules are thousands of times smaller than other sealer types. This is especially important for sealing granite countertops in the kitchen.

The specialized molecule then breaks apart while displacing the water molecules.



Sealers | What You Need To Know | Duration 1 Minutes 44 Seconds

The remaining molecule chemically repels oil and water like opposing magnets repel each other. The net effect of this reaction is to change the “surface energy” of the stone.

A low surface energy liquid like oil will penetrate a high surface energy material like granite.

Thus, when you spill something, instead of the stone quickly absorbing the liquid like a hard sponge, it just beads up on top of the stone dramatically delaying absorption for easy cleaning. One properly applied coat is much better than two thin ones. So, the advantage of applying a sealer is that it allows far more time to clean up a spill. We discovered after we left a bottle of mouthwash on the bathroom granite that it was never sealed because the chemicals from the mouthwash seeped from the bottle into the granite! Not only did it make the granite shiny but now nothing sticks to the granite and it actually appears brighter. I purchased the installation from a box store with the promise that they were adequately sealed. I think it has paid for itself in just the savings on 6 month reapplications of regular sealer. It remained looking “wet” for quite some time when applied, leading me to think the stone had very little porosity. According to photos provided by the customer the “stains” were actually etch marks which sealers cannot prevent. In some cases, 2 or 3 coats are needed to effectively seal the countertops and achieve maximum time to absorption / stain resistance where water readily beads on the surface.

There are clear instructions on how to apply the sealer and the actual application was pretty straightforward. It left no shine or residue on the stone and we are hoping it will reduce mildew due to its nano chemical bonding properties. Fumes quickly dissipate as the liquid part of the sealer totally evaporates and the sealer cures. Sealers dramatically increase time for liquid to absorb giving you more time to clean.

After, they take at least 15 minutes to absorb water and the water initially beads up. More importantly, water beads and spills wipe right up without leaving a mark. The price reflects the advanced chemistry and permanent bonding, which no other retail sealer provides. Senguard covers/seals 40% more than standard sealers, so you need a lot less volume. I had a question about the product after receiving it and their customer service answered promptly and was very helpful. One tip – make sure your countertops are totally clean before starting.

One bottle covers an estimated 50 – 200 square feet depending on the porosity of the stone.

In most cases, you will need to re-apply the sealer in 2 to 5 years. However, long-term it is the better value when you consider that you’ll have to buy and apply any other sealer many times to get the same protection.

Thus, these molecules are able to penetrate far deeper into the stone and to spread into every pore, crack, fissure and crevice more effectively so you get more consistent and complete coverage. These molecules are also engineered to form chemical bonds directly with the stone that are as strong as the bonds holding the stone itself together. Part of the molecule is attracted to water, so it is drawn into the stone by water molecules in the stone. It leaves behind a hydrophobic and olephobic molecule that binds directly with the stone lattice. Other marble & granite sealers rely on weak hydrogen bonding and mechanical holding (clogging the pores). It’s important to let the stone absorb as much sealant as possible (without letting it dry on top) rather than trying to spread the sealer around to cover as much as possible. Also, depending on the porosity of the stone two coats (or even three for very porous stones) may be necessary to properly seal the stone in one application.

Performing the water test after the first coat has cured for 24 hours will help determine if the stone is effectively sealed or if a second coat is necessary.

Sealers work by radically reducing the rate of absorption of a stone. If neglected, a liquid exposed to the surface for an extended period could still potentially stain no matter what type or brand of sealer used. No impregnating sealer will prevent chemical etching that leaves dull and light-colored spots on calcitic stones like marble, travertine, limestone and (rarely) some granites. We recently purchased a home and it had the darkest and cheapest granite in the kitchen and bathrooms but that wasn’t the worst part.

So we decided that even though we didn’t like the granite we could not afford to replace it so we had better protect it until we could replace it. I can see reflections in it so it looks lighter since the items reflecting are light. My kitchen is the sole focal point in the house so protecting my investment is the highest priority. I finished sealing them several days ago and see a remarkable difference already. Yes, all sealers have a smell, however, the smell will dissipate quickly with open windows. We are about to buy another bottle for our new bathroom counters.

The added protection makes it much easier to maintain the stones against usage stains. Your method of answering questions online by a ticket number is very efficient. In most cases it is sufficient to simply open windows to provide good ventilation during application. Once sealer cures it is completely inert, non-toxic and safe for food prep. Taking 5 hours to absorb water and darken after sealing is excellent.

The counters look great and the water beads up very nicely. The installers sealed the countertops with another product.

How To Seal Granite Countertops by countertopbracketsonline.com

But why should you seal granite countertops in the first place? It’s the result of ignorance in the stone industry and maybe even malicious intent by sales and marketing people representing competing countertop materials. The stone industry set out to solve the concerns of granite countertop staining by soliciting chemists to develop the best sealer for stone.

The sealing substance is delivered inside the stone by natural absorption. This prevents changes to the color or the finish of your stone surfaces. Several commercial granites won’t absorb anything because they’re so dense. If you apply it anyway, some will remain on the surface of the stone and it will give the impression that the stone is damaged. Some of the best stone surfaces can look “stained” after sealing them. Very dark stone and dense stone won’t need sealing, but light color, less dense, and porous stones will. Some granites never need sealer and should never be sealed (especially black stones). Granite is very different than marble or limestone, so make sure you are dealing with granite before anything. Test your stone to see if it needs sealer by putting a few drops of lemon juice in an inconspicuous place. If the drops take a minute or so to be absorbed, you can protect the top with sealer.

And contrary to what you may have heard, sealing granite isn’t always a necessary part of granite care. These sealers are unfortunately very common and many of the misconceptions about sealing granite come from their widespread use.

Unlike silicon sealers, these will not evaporate or go through any type of natural degradation. Fluorocarbon alphatic resin is more expensive than lesser quality sealers, but you get what you pay for. And if you’re using a high quality alphatic resin granite sealer , you don’t need to keep re-applying over the years. Denatured alcohol, it turns out, does wonders for cleaning granite and cutting through film buildup on your counters.

Check out the full line of hidden quartz and granite countertop supports. Sealing granite has become such a misunderstood practice and worse, a misused marketing weapon. Just because a material like natural stone is delicate and hard to maintain, doesn’t mean it should be sealed.

Stone sealers or impregnators are below-surface penetrating sealers, not topical hard shell sealers such as those used on wood floors or furniture. The most important part of stone sealing is to thoroughly clean the surface prior to sealer application.

If you’re going to place food or drinks on a granite table, you will probably need to seal it. If you have a marble table or limestone table, you will definitely need to seal it. If dark spots appear quickly, the stone is potentially a problem since it is reacting with an acid. If the lemon juice doesn’t absorb at all, the stone does not need to be sealed. As a granite fabricator and installer, we always degrease countertops and give them their final cleaning with denatured alcohol.

How To Protect A Granite Countertop: 7 Steps by wikihow.com

Learning how to protect a granite countertop will allow you to keep it looking beautiful for years. The first step in protecting your granite countertop is making sure the installation is safe and secure. Otherwise, the cabinets may partially collapse, leaving the granite to crack as it falls. This is especially true for liquids with a deep color like red wine on a lighter granite. To test if your granite requires a sealant you will need water, lemon, and baby oil and a sample of your stone.

Apply a drop each of lemon juice, water, and mineral oil and allow it to sit for 10 minutes then wipe away. If your sample of stone foams when the lemon juice is applied or the surface appears dull and pitted, this indicates that your stone has calcite and is susceptible to acids. It will be damaged by coffee, soda, orange juice, and other acidic products. If you find that your granite does indeed require a sealer, be careful to use only the cleaning products on it that the sealant manufacturer recommends.

While it is remarkably durable, granite is still susceptible to damage of various sorts if not properly protected. Because of the granite’s weight, your lower cabinets need to be of sturdy construction and affixed properly to the wall. A licensed contractor can make the assessment of your cabinets’ strength if you are unsure. The next important step in preventing discoloration is to clean up spills. Containers such as olive oil bottles are often hard to keep completely dry, acetone from fingernail polish remover can remove your sealant, cosmetics and beauty aids may contain chemical residues on the outside that will react with your counter over time. Water and mineral oil will evaporate, lemon juice tests for etching (calcite reaction to acid) which can permanently damage the stone. Dark stains from the water or mineral oil indicate that your stone is absorbent and a sealer may help to protect your stone from stains.

In general, maintaining a granite counter is wiping it down with a damp absorbent cloth or sponge then weekly cleaning with a mild detergent.

It creates a barrier to protect all natural stone against staining, etching and soil buildup.

To allow the sealer to cure to the surface, wait 24 hours before polishing. But, suggest that you let the sealant work its way thru for at least 12 hours before polishing. It is made for natural stone and the sealer is not supposed to be for shine. It went right on just like the instructions said and seems to be sealing very well. You can see that water is penetrating the seal-coat when a wet washcloth is placed on the granite.

Another factor could be the length of time since the stone was last sealed. As a result many chemicals particularly cleaning chemicals can damage the stone. When used daily it cleans the surfaces and reinforces the anti-stain protective treatment. It easily removes burned on foods and will not scratch delicate glass/ceramic surfaces.

It creates a barrier to protect all natural stone against staining, etching and soil buildup. Granite and all other natural stone varies in porosity depending upon from where it was quarried as well as the color of the stone. We want to help you care for and maintain your natural-stone surfaces. Neutral product ideal also for the most delicate natural stone surfaces. Use regularly to keep new ranges looking beautiful or to bring older ranges back to life.

Do Granite Countertops Need Sealing by countertopspecialty.com

You risk creating unwanted sealer haze problems and/or the sealer simply won’t absorb, so it’s an exercise in futility. In other words, testing tells you if the granite you want to buy will stain easily or if a particular stone etches from acids.

For your kitchen countertops, you want a stone with very low absorbency and does not etch. With some colors it can be stated with near certainty that it will or will not need sealing. We’re noticing pitting in many places and we’re worried that it’ll worsen into deeper divots. Now, a month later, we’re seeing and feeling several more rough pitting areas (on flat areas and especially on edge surfaces where there is a black spot) and don’t know if we should call back, or expect that they can help.

Also, using soap to clean is okay, but not the greatest suggestion. You may end up having to apply several coats and then re-seal every year. Even though we know of many stones that don’t need sealing, it is a natural product and variations can and do exist. In reality, it’s very easy to determine if and/or when you should seal or re-seal or not. Ubatuba granite most often does not need sealing because it is typically a very dense, low-absorbency stone that is naturally stain-resistant. In fact, if this is the case, then this stone likely cannot be sealed even if you try since the granite sealer must absorb to work.

All that will happen is the sealer won’t absorb and will leave a streaky, hazy film that will require chemical stripping. So my concern is that if the granite countertop needed to be sealed more often than every few years that the previous owners did not do the required maintenance on it. The great thing is that it’s easy to determine if and when your granite countertops or any stone installation needs sealing or re-sealing. You may read (mainly from granite sealer manufacturers) that you should do it every 3-5 years.

Some say “all” granite needs sealing every year and others say only sometimes. You can’t simply go by the “name” or “color” of the granite (or any stone). No need to guess, just test your granite to accurately determine if it needs sealing. You should not apply a granite sealer “just to be safe” when testing shows your countertop or floor doesn’t need it. Another great thing about the water test is that you don’t even have to know the name, or type of stone, or anything else about the stone.

You’ll learn the characteristics of that stone are and what will be required for maintenance. Staining can be controlled by sealing but, in general, more porous stones and those that etch from acids are way more troublesome as kitchen countertops.

I understand dark/dense granite countertops do not require sealing at all. The best way to determine for sure if your particular slab needs a granite sealer is to run the test for sealing granite countertops. Recently our installer come out to fill 2 divots/chips were told that the rest should be fine. Should we re-seal though we were told we shouldn’t have to but every 2 years, or, knowing granite, does this sound like a defect that we should address further with the installer/fabricator? Do you have any recommendations to halt the pitting or are we alright and just need to live with the pitting and try not to worry. We want to preserve the investment but don’t know what is reasonable or a concern to deal with. It’s very easy to use, dries clear, allowing the natural color / pattern to show for an invisible repair.

Typically granite countertop installers will use color-matching epoxy resins that are always very obvious, but that was the best that could be done until the above product, which is far superior. It won’t harm the granite, but it builds up over time & makes granite look dull. Even if you got a great deal on this stone, it’s worth it to pay more for a better quality stone.

Is this typically absorbent, and so would typically need a sealant? Stone pros can make very good guesses on many stones, but the only accurate method to know for sure is to water test the stone. I have read about people having trouble with etching and hazy or discoloration issues with their countertops. Tropical brown granite is very stain-resistant (nearly stain-proof really) and almost certainly will not need sealing and would just create a problem with it drying on the surface creating a dull haze if you tried to apply it. So, test your granite and you’ll get a definitive answer for yourself whether or not to seal it. Many new “granite cleaners” have popped onto the market in the last few years as stone countertops and floors have become so common. Unfortunately , even many working in the stone industry don’t have accurate knowledge regarding granite sealers and sealing granite countertops. Of course, being a natural product performance characteristics such as absorbency can vary (like the color and pattern), which is why you test it. However, if testing shows that it takes a long time for liquids to absorb into your ubatuba granite countertop then sealing won’t be of any benefit. I don’t know much about granite, are they installed already sealed?

By the condition of the house the previous owners were not very good at maintaining. Most granite countertops will need a granite sealer at least on install. What type of cleaning products used (harsh cleaners will degrade the sealer, which is why you should only use products safe for cleaning marble & granite countertops. All you need to do is perform the “water test” or “lemon juice test” as noted above.
