Does GBS Penetrating Sealer penetrate concrete of all densities i.e., 2-4 inches?
A. Yes. Most concrete is poured 3,000-4,000 psi and GBS Penetrating Sealer penetrates extremely well. Our GBS Penetrating Sealer was used on a Nuclear Power Plant on which the concrete that was poured was 8,000 psi (extremely dense and hard) and then GBS Penetrating Sealer was applied. Two cores were diamond sawed out to test for penetration via ASTM Test 123D by Keeler & Long of Pittsburgh Plate Glass. The results showed that it penetrated 2.25 inches. Q. Is GBS Penetrating Sealer affected by under floor heating? A. Since under floor heat does not get that hot, GBS Penetrating Sealer in the concrete will not dry out or lose effectiveness. Also GBS Penetrating Sealer will not affect the plastic tubes since the polyester polymer is inert. Q. Is the curing time the same on an aggregate, as on a masonry floor? A. The curing time for aggregate should be the same as concrete. If the aggregate is stones, they won’t absorb very much. The concrete that is bonding the stones is what you need to
