HardSeal is designed to block off-gassing of VOCs and formaldehyde usually found in composite wood products. To seal slate, order a sample of our AFM Mexeseal
Mexeseal is a non-toxic topical type sealer that may work if the stone has some porosity. The only way to know for sure is to test with the sample to see if it bonds well and if you like the look. It comes in both satin and semi-gloss finishes.
