Are sealers non toxic after drying or still be unsafe?
Sealers - We are making a granite kitchen countertop. Would like to seal it to prevent the grout from staining. Are sealers non toxic after drying or will the residue left over still be unsafe?
ANSWER – I assume you are using granite tiles since you mention grout joints, rather than seams which are the joints between larger slabs of granite.
There are a variety of sealers on the market that are recommended for granite tile countertop application. I would assume they are safe, but the only way to be sure is to look at the specific products Material Safety Data Sheet (MSDS) where they must disclose any information about their product which could be harmful.
If you go to our Cleaners and Sealers on this website there is a list of sealer manufacturers with links to their websites. Click here to go to Sealers. Good Luck!
