Best Granite Sealer


QUESTION:

I'm wanting to find the best granite sealer available, but not sure how to know.


Application has to be simple enough for a novice (but handy) person like myself can handle.

New construction so this will be its first sealing.

Also, do most granite installers seal their installations? Thanks.

ANSWER:

Choosing the best granite sealer can be challenging. Many sealers on the market will do an adequate job sealing granite countertops. But yes... there are significant differences.

We've used all the top brands, but have found some that are more effective, durable, and cheaper. You'll find all our recommended sealers at the Stone Care Center.

We'll explore why as we go, but cut to the chase...

The best granite sealer currently available is SenGuard Marble & Granite Sealer. Conveniently, it is also easy to apply and comes in a kit with all needed materials including both DVD and written instructions.

Let's take a closer look and learn why one is better than all the others...

Common granite sealers now available from the most recognized brands (Dupont/Stone Tech, Miracle 511, Aqua, SCI) are of the fluorcarbon type, which we refer to as "standard" or "last generation" sealers.

In other words, the chemical technology is good (and was the very best a few years ago), but durability and effectiveness vary and all will need to be re-applied periodically.

Obviously, a key consideration for choosing a granite sealer is "how long will it last". That answer is not cut n' dried. Each sealer will have a range depending on certain variables.

Frequency of re-application depends on the quality of sealer, quality of application, absorbency of stone, and type/quality of the cleaning products used.

The majority of "last generation" sealers will last between 1-3 years before re-application is needed.

There is one "last generation" sealer that is more durable and will commonly last 5-6 years under ideal conditions & treatment. Naturally, this is our pick in the "last generation" class and can be found at the Stone Care Center.

SenGuard is in a higher class than those described above. "Top shelf" so to speak.

The SenGuard granite & marble sealer employs the most advanced chemical technology forming permanent bonds for the most effective and durable coverage requiring only one application.

This is much different from how standard sealers work.

We refer to this type as a "next generation" sealer. No other retail sealer is capable of this which is a MAJOR advantage providing better long-term value and performance.

Two or three coats may still be needed (depending on the porosity of your stone countertop) during that one application in order to effectively seal the granite, but then no resealing is necessary.

Senguard sealer is a more expensive sealer up front, but is cheaper in the long run since you don't have to re-apply it every few years like you do with the "last generation" type.

But first, you should perform the water test for sealing granite countertops to determine if your natural stone even needs sealing.

All the sealer manufacturers and many installers will tell you (incorrectly) that "all" granite, marble and stone "must be" sealed.

Well, this is just not true, but good for sealer sales!

Some granites (and many marble and travertine slabs) are so dense that a sealer won't absorb properly or at all, so no need to try. Nothing else will absorb either, so no risk of staining.

Testing is the best way to determine if and when a stone needs sealing or re-sealing. Even if the absorbency characteristics of the your stone are well known, you should still test. Natural stone products don't always behave exactly the same.

If testing shows that you should apply a granite sealer, then Senguard is the "best granite sealer" to apply.

For "last generation" sealers (that will need re-application), then I'd suggest using one of these recommended marble and granite sealers.

Most installers do not apply a sealer. Applying a granite sealer is not considered a "standard" part of a granite countertop installation.

It is an add on... as it should be since the installer will never know if the stone you buy will even need sealing (until testing it as explained above).

Inexplicably, many installers are ignorant about sealer application and will apply or tell the client to apply a sealer when unnecessary or provide incorrect instructions such as to "let it dry on the surface".... wrong. But again, testing will remove all the mystery and give you a definitive answer.

So, really it is best just to tackle this easy job and apply a granite sealer yourself when needed. It doesn't require any skill other than following simple directions. It is basically a pour on, let absorb, wipe off procedure.

There are a couple key points to ensure proper application, but again very simple instructions to follow.
