GBS Penetrating Concrete Sealer was designed to prevent moisture intrusion. It will certainly stop some food from staining but it will not prevent all oils or strong acids or alkaline cleaners. Normally veneer plasters are very porous and should be sealed topically for this type of application in a kitchen. For that we suggest our AFM WaterShield or even our AFM Zero VOC Semi-gloss paint.
