Discuss Does Sealing The Back Of Stone Impair Adhesion? in the Canada Tile Advice area at TilersForums.com.
I do know one thing is that I would rather tile a room and then seal it before and after grouting rather take all the tiles home and spend the evening sealing them up
What are your opinions regarding sealing stone by sealing the full tile, front, back and sides before fixing. Do you think it would impair the adhesive bond ?
I always seal tiles before grouting on edges and top.
Bottom of tiles have full buttered surface in adhesive.
I don't seal the back edge because it's completely buttered. If it was sealed the addy wouldn't completely grab the tile due to using porosity to mechanically bond the two together.
Look at it from a different angle,
I prime all substrates so it helps adhere and regulates the porosity and dusting.
If I was to use something which impregnated the substrate for the use of stopping staining and absorption then the adhesive wouldn't properly adhere to the substrate..?
The only stone I have sealed the back of is basalt. Don't see a problem with sealing the back of stone, depending on the type of sealer. Eg. Fila PW10 is specificially for sealing the reverse of stone.
