Which Granite Sealer To Use?
Marble & Granite Sealer Comparison
QUESTION: I'm wanting to find the best granite sealer available, but not sure how to know.
I was wondering... are there any reviews or studies ranking the performance of the different granite sealers?
I have looked at two in particular: MB Impregnator/Sealer for stone and Stonetech Bulletproof Stone Sealer. Any other suggestions?
I understand your confusion. 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
. The following granite sealer review
and discussion will provide the desired perspective, answers and advice to help you confidently compare, evaluate, and decide which sealer to use.
Stone Sealer Evolution"How long will it last"
is typically the key question. That answer is not cut n' dried. Each sealer will have a range depending on certain variables.
The chemicals and ingredients used in stone sealers have evolved (and are still evolving), so they get better and more durable, but there are still plenty of low-grade sealers on the market.
A scientific sealer comparison would be great, but that's a tricky task.
A true comparative test would need several years with samples undergoing "normal" use and cleaning, or at least some type of an accelerated process that simulates years of use in a short time.
Either way... quite a project and may be of little use by the time completed as new or improved products hit the market.Years ago Stonetech was cutting-edge
, and I've recommended bulletproof in the past. It's a fluorocarbon aliphatic sealer that works by plugging up the pores (as most sealers do).
Fluorocarbon aliphatic sealers were once the very best class of sealers. Most of the recognized brands are now of this type (which is no longer the most advanced formulation).
Stonetech is still a decent
, but average product similar to others in its class like Miracle 511, Marble Life, Stonecare International, Rock Doctor, Black Diamond, Weiman, Aqua Mix, etc. MB Stone Sealer is far better
... very good product, much more durable and longer-lasting than Stonetech and the rest of the "last generation" sealers.None of the above are the best
anymore, though. Sealer technology has advanced far beyond how "standard" sealers (like Stonetech, MB, 511) work.
Development of high-quality permanent stone sealers
has left these behind.
Which Marble & Granite Sealer is Best?The top product now
for sealing granite & marble countertops (and other natural
stone or porous surfaces) is the SenGuard DIY Sealer Kit
.SenGuard is currently the best sealer available.
Using nano-technology it's the most advanced and durable sealer technology yet invented. Senguard forms permanent
bonds with the stone, which means... only one application necessary... no re-sealing!
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.
Obviously, this is a big step up from the "last generation" fluorocarbon aliphatic sealers that require re-application.
SenGuard is also super-easy to apply and comes with instructional DVD and book, etc... everything you need to do the job properly.We still recommend
the Stone Care Impregnating Sealer by MB
. It is by far the best of the "last generation" sealers.
The cost is less than SenGuard up front, so it's a good choice if on a tight budget or when sealing a large floor. However, it will need periodic re-application
, so time / effort / cost catches up with you in the end.
All considered (total lifetime cost, performance) SenGuard is easily the best value for all countertops and vanities.

A couple other permanent sealers (Granite Shield, Permatreat) are also on the market, however, they are much more complicated to apply.
Granite Shield requires a multi-step application procedure and is more expensive than Senguard which is very simple to apply.
Permatreat can only be applied by a licensed technician (expensive). For a complete explanation of sealer technology
, different types of chemical formulations, how sealers work and how to apply sealers correctly check out the All About Sealing Granite & Marble
e-book. It doesn't break down every brand, but it does thoroughly cover this topic, so consumers can get a detailed understanding about sealers. Just remember
that no sealer will work as well as designed without proper application. It's not a difficult job, but you must completely saturate the stone without letting the sealer dry on top.
Follow the directions carefully and you'll do fine.First and foremost, be sure to perform
the sealer application test
to determine if you even need to seal the stone. If you don't know...
and many don't... some stones just don't need sealing and trying to apply one can cause problems with a hazy film
Now, Crystal Yellow almost certainly will need sealing, but it's always best to test any natural stone first.
