Why does the grout keep cracking?

Too much water or polymer additive in the grout mix is a common problem. Cracked grout is frequently the result of weak grout structure. The liquid in the grout mixture inevitably evaporates, as it was designed to do, but excessive evaporation can leave pinholes that will leave it vulnerable to cracking.

How many coats of grout sealer is needed?

(Generally speaking, it takes one to three coats of sealer to achieve adequate protection.) After the second coat dries, test the surface with a few drops of water.
