Which Granite Sealer To Use?
Marble & Granite Sealer Comparison
QUESTION: I was wondering... are there any reviews or studies ranking the performance of the different granite sealers?
I just purchased granite counter-tops (crystal yellow), and I want to seal them. However, there are many different sealers out there.
I have looked at two in particular: MB-4 Impregnator/Sealer for Stone, and Stonetech Bulletproof Stone Sealer. Any other suggestions? Thanks for your help. Sincerely, LJ
LJ, I understand your confusion. Although sealing granite and marble is a simple task, getting the right answers and deciding how to go about it can give people fits sometimes. 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.
The chemicals /ingredients have evolved (and are still evolving), so they get better and better, but there are still plenty of low-grade sealers on the market.An explanation of sealer technology
, different types of chemical formulations, how sealers work, how to apply sealers correctly is found in 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.
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 accelerated process that simulates years of use in a short time.
Either way... quite a project and maybe 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 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-4 Stone Sealer is far better
... very good product, much more durable and longer-lasting than Stonetech. In fact, it used to be the best on the market until recent technological advances discussed below.
Stone Care Pro Impregnating Sealer
is also very good in this class and cheaper than MB for essentially the same performance.
However, today... none of the above would rank as the best
. Sealer technology has advanced far beyond how those two sealers work. Development of high-quality permanent stone sealers
has left these behind. 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
utilizing the most advanced and durable chemical technology yet invented forming permanent bonds with the stone, which means... only one application necessary... no re-sealing!
Obviously, this is a big step up from "traditional" 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 Pro Impregnating Sealer
and MB-4 Sealer
. These are by far the best of the "last generation" sealers.
The cost is less than SenGuard up front, so these are good choices if on a tight budget or when sealing a large floor. However, both 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. 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
