Is thinset waterproof? - Kylon Powell

Writer John Campbell

What happens if the thinset becomes wet?

Thinset is typically 80% cured after 24 hours in moderate indoor temperatures. 80 percent is sufficient to complete any task. You had some water on your floor after 18 hours. Water now has little to do with your thinset.

How long does it take for thinset to cure completely?

Thinset. Thinset mortar, also known as dry set or dry bond mortar, contains a water retaining additive that aids in curing and hydration. It is commonly used for tiles and counter-tops. Also, thinset mortar takes 24 to 48 hours to cure.

Is it possible to grout while the thinset is still wet?

Before grouting the tiles, you should wait at least 24 hours. You may notice that the thinset edges or thinset showing through the grout lines appear dry. Don’t be taken in by this. Because the thinset beneath the tiles is not receiving as much air as the edges, it is not fully cured.

Is it possible to use Thinset outside?
