Sealing resined granite

[oldhousejunkie]

Any advice appreciated. I am looking at installing resined Giallo Vicenza as a kitchen counter top. The stone is fairly water absorbant. I want to seal it. I am debating using a water based flouroplymer vs. a solvent based flouropolymer sealer, but am concerned about reaction with the resin and/or safety of the flouropolymer etc. as a kitchen counter top. Also the resined test slabs we obtained from the yard have hair-line cracks on the surface. Is this normal after handling a resined slab or is this a sign of trouble? Thanks. Oldhousejunkie

Hi there :) What should we call you?

I would reject the slabs if they didn't look the way I wanted them to. Why by something that creates questions in your mind?

Water based versus solvent based. I choose solvent, but, I would like to know which brand you are using.

The resin on the slab will not react negatively with the impregnating sealer. The worse case scenario you will have is that you wipe off as muchg as you apply in the final cleaning stage.

I only use oil based penetrater, like miracle in the green jug or 511. Seal your stone twice with liberal amounts and buff dry after a few minutes. Most resined slabs will be darker on the surface, leaving the edges lighter. And depending if the edge is laminated and how its laminated, you may see a cross secton of the resin on the edge at the lam line. It the edge is alot lighter, then your fabricator should be able to apply something to darken it prermantly.

A note on fissures, Most stone has some kind of fissures or "hairline cracks". They add character. If the stone holds together during the fabrication and install process, then its going to be ok.

A fissure has characteristics of simple cracks, if you note one during the slab review phase of the process and it causes you to question the material, then I still say pass on it and get something else.
