RE: Marble and Granite Countertop Sealers (Follow-Up #4)

Cat mom -

Can you share who the manufacturer of KR-33 is?

There are lots of products out there - some good, some not
so good, so I always try to test them myself - so I can
see for myself what works best for us and our customers.

I have had outstanding results using "511 Porous Plus"
that is made by Miracle Sealants.
I have used 511 PP for almost 15 years
now - without a call back.
It lasts anywhere from 5 to 7 years after
one application. I use it in my own
home too - so that should say something
about it's integritty.

Another product that I have heard nothing
but good things about is
Surface Treatment Technologies -
I will be testing their sealer here in AZ soon.

Let me know who KR-33 is made by, or where it can be obtained - I'd like to try it too.....

Kevin--I don't know where how to get the K.R. 33 except from my fabricators. I know they import it from Italy (according to them). It is made by (?) Industria Chimica General in Modena/Italy. http//

On the can it says: Brightens, polishes, protects marbles and granite. It definitely shined up/polished the granite on the island, which was NOT as shiny/polished looking as the granite on the other counter spaces.

I don't think it's supposed to last 5-7 years though, so I don't know how it would compare to the 511PP.

I have to tell you, that I had posted on another thread a few months ago, about some whitish rings that appeared on our granite after placing a chilled wine bottle on it (different bottles, different occasions, and it happened with a beer bottle, too, I think). Some of our very helpful resident advisors here on GW suggested that our granite (Labrador Golden Flake) wouldn't need to be sealed, as it is a black granite, and that it was likely an excess of sealer that caused the rings to appear. I can't imagine not using it though, it really did a fantastic job of polishing up the stone, and I feel better knowing that it is protected against staining (however likely or unlikely that is to happen). Care to weigh in?

KR 33. It's an Italian sealer/polish or restorer (I don't remember exactly what it says on the can); it's the only one our fabricator uses. It's a penetrating sealer and is very easy to apply. Our island granite for some reason, didn't look as polished or glossy as the rest of the granite in the kitchen after install. A few months later, after I'd gotten my own can of the stuff, I went over it with some of the KR 33. What a difference! It really brought out the shine or lustre of the stone.
