QUESTION:

Do granite countertops need sealing? From what I understand dark/dense granite countertops do not require sealing at all.

I have the BUTTERFLY GREEN (Brazil) countertops and would like to know if this particular granite requires sealing. Thanks.

ANSWER:

Very often Verde Butterfly will not need sealing, but since all granite is a natural product even granite countertops of the same color or variety can have slightly different characteristics.

With some colors it can be stated with near certainty that it will or will not need sealing. I'll say that most likely your butterfly green (verde butterfly) will not need it, but......

The best way to determine for sure if your particular slab needs a granite sealer is to run the test for sealing granite countertops.

Very simple and you'll get a definitive answer.

If the test shows you should apply a granite sealer, I suggest using one of these recommended impregnating sealers.

And thanks for the photo... always helpful.

Good Luck,
Ryan

Does Dark Granite Need Sealing

QUESTION:

Does dark granite countertops need sealing?

ANSWER:

While it is true that many dark granite countertops do not need application of a granite sealer (since they are already too dense to absorb liquids and stain) and while it's also true that many colors/varieties are know to either always need sealing or never need it... the only correct answer is... maybe... or it depends.

Granite is a natural product, therefore, the particular characteristics (like absorbency) of different colors and even different granite slabs of the same color can vary... sometimes widely.

So, the only way to know for sure if sealing granite would be beneficial (or re-sealing) is to perform the "water test" noted above.

Using this test will give you the most accurate answer for your unique granite countertop, so you can confidently answer the question... do granite countertops need sealing.

If testing shows your countertop could use a granite sealer then the best sealers will be one of those we recommend at the Stone Care Center with SenGuard being the very best currently available.

However, you should not apply a granite sealer "just to be safe" when testing shows your countertop or floor doesn't need it. This just creates unwanted problems and the sealer won't absorb anyway, so it's an exercise in futility.

Another great thing about the water test is that you don't even have to know the name or anything else about the stone.

The water test will tell you if it could be / should be sealed, which is why you should perform the test (and/or the Lemon Juice test) prior to purchasing any stone so you know what it's characteristics are and what will be required for maintenance, etc.

Good Luck,
Ryan

Should Kashmir Gold Be Sealed

by John M
(PA, USA)

QUESTION:

I am having kitchen countertops installed using Kashmir Gold granite, from India.

The absoption is given as 0.38%, I don't know if this is average or better.

I was wondering if this is a good choice and if this type of granite should be sealed and how often?

ANSWER:

Yes, Kashmir Gold must be sealed and often, so you're smart for looking at absorbency rates and asking before installation because I would advise that you do not install this stone in your kitchen.

Kashmir granite is typically highly absorbent and easily stained even after sealing.

In fact, this stone tends to be difficult to seal.... it's just too porous. You may end up having to apply several coats and then re-seal every year. I've known some Kashmir to need re-sealing every 3-6 months.

Of course, every slab is different (kashmir can range from .3 to .5!), so one slab of Kashmir may seal well enough to be satisfactorily stain-resistant, but you are risking endless frustration with this stone.

Even if you got a great deal on this stone, it's worth it to pay more for a better quality stone.

There are so many beautiful granites that have low absorbency rates (.05 - .3 where .2 is essentially non-absorbent), not prone to staining or staining can be easily controlled with a granite sealer... so why chance it with Kashmir.

Look for something else and perform the "water or lemon-juice test" (links above) on a sample chipped off the exact slab you are considering to determine if it will be suitable for the kitchen.

Good Luck,
Ryan

To Seal or Not To Seal Tropical Brown


(West Salem, WI USA)

QUESTION:

We are purchasing Tropical Brown granite countertops (not installed yet).

We've never had anything but laminate countertops until now. I have read about people having trouble with etching and hazy or discoloration issues with their countertops.

You mention that sometimes sealing granite is unnecessary. How do I know if mine needs sealing?

Have you heard of a product line called "Granite Gold"? I also have seen a product called "Perfect Counters". How do I know if a cleaner is good or will be harmful to my countertop over time?

ANSWER:

Tropical Brown is a very dense granite with low absorbency. Good choice! Granite does not etch. Marble, travertine, limestone and slate can etch or become discolored upon contact with acids... not granite, so you're safe there.

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.

Accordingly, you should never apply a granite sealer "just to be safe." You should only apply it if testing (described above) reveals liquids absorb quickly.

This is the case with any stone. Even though we know of many stones that don't need sealing, it is a natural product and variations can and do exist.

So, test your granite and you'll get a definitive answer for yourself whether or not to seal it. But I'll tell you that this is one variety/color of granite that I'd be surprised if it needed or could be sealed.

Regarding granite countertop care products....

There are many out there and I have used plenty, but still there are some I haven't used or heard of. Many new "granite cleaners" have popped onto the market in the last few years as stone countertops and floors have become so common.

Some are good and some are mediocre to worthless.

The products I think are the very best and recommend with complete confidence are found at our Stone Care Center.

Good Luck,
Ryan

To Seal or Not To Seal New Granite Countertops

by monica
(omaha, ne usa)

QUESTION:

not sure if new granite counter top (uba tuba) needs sealed.

ANSWER:

Whether or not to seal granite countertops is a common question and point of confusion for many.

Unfortunately, even many working in the stone industry don't have accurate knowledge regarding granite sealers and sealing granite countertops.

In reality, it's very easy to determine if and/or when you should seal or re-seal or not. All you need to do is perform the water test for sealing granite countertops.

This simple test will give you all the information you need to know to decide if you should apply a granite sealer or not to any stone even if you don't have a clue what the name or type of stone it is.

Ubatuba granite most often does not need sealing because it is typically a very dense, low-absorbency stone that is naturally stain-resistant.

Of course, being a natural product performance characteristics such as absorbency can vary (like the color and pattern), which is why you test it.

If testing reveals that your ubatuba is absorbent enough to warrant application of a granite sealer, then use one of the sealers we suggest (links above) with Senguard being the most advanced, durable and best granite sealer currently on the market.

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.

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.

And you should never apply a sealer "just to be safe". Doesn't work that way. All that will happen is the sealer won't absorb and will leave a streaky, hazy film that will require chemical stripping.

So, perform the water test and you'll have your answer!

Do Granite Countertops Need Re-Sealing

by Carolyn
(New York)

QUESTION:

I just bought a house with granite countertops. I know the kitchen was re done within the last 6 years.

I don't know much about granite, are they installed already sealed? Do they need to be resealed and how often should this be done?

Does the color of it change the frequency of sealing? It is on the darker side, it has brown, gold, black and tan. By the condition of the house the previous owners were not very good at maintaining.

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. Any help you can give would be appreciated. Thank you!

ANSWER:

Most granite countertops will need a granite sealer at least on install. "Most" not "all". Many granite countertop colors and patterns are dense enough that they never need sealing and don't stain.... they just don't absorb any liquid.

Mostly these non-sealing types are the darker colors.

Whether or not the granite countertop needs resealing is a function of:

1. How porous the particular granite is
2. What type/how good of sealer was used
3. How well it was applied
4. 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.

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.

All you need to do is perform the "water test" or "lemon juice test" as noted above.

If it does need a granite sealer re-applied we recommend using SenGuard Marble & Granite Sealer. It's by far the most advanced and durable available forming permanent bonds.

Frequency of sealing is not exact. You may read (mainly from granite sealer manufacturers) that you should do it every 3-5 years. Well it all depends as noted above.

So, you re-seal when testing shows you need to re-seal whether in 1 year, 3 years or 10 years.

Cheers,
Ryan
