we are going the have white river granite countertop (from Granite outlet) installed. please help us ...because we get mixed info from contractors and stores about the glue/adhesive that we should use. some contractors said that they will use liquinails, or 100% sillicone, or others said nonsillicone...we don't know what is the best for white granite. they said that sillicone will 'bleed" in and leve permanent spots, other that liquinails should not be use for granite even if it said is for granite. other said that granite beeing so heavy should not pe glued at all? also about sealant, should we apply sealant same day after the granite was installed(the addesive not yet dry)...wait couple days...how many layers, after how many minutes between layers? or we should have the fabricators/contractors apply sealant before installing? please help us with info.
