Can Stone Preserve products be used over other brands and types of sealer and care products that may already be on existing countertops?
Yes. However, the sealer will only be effective if it can penetrate into the surface of the stone. Therefore, if the stone has a different brand or type of sealer already on it, the Stone Preserve sealer may or may not be able to penetrate into the stone depending on how much of the previous product remains. As for the care products, they can be used effectively over other brands or types of sealer.
