What size of grout joints can be used with Ultracolor Plus FA?

1/16" to 1/8"

Which is better, a water-based or solvent-based sealer?

It used to be said that solvent-based products were more durable and longer lasting than water-based products. In today’s world, we have water-based technology that is equal to, or better than, solvent-based products. Because of their unique molecular construction, MAPEI’s UltraCare Penetrating Plus Stone, Tile & Grout Sealer and UltraCare Penetrating Plus SB Stone & Porcelain Tile Sealer are formulated for use on both porous and dense surfaces.

Where to buy

Why did my grout dry lighter than the color I purchased?

There can be different explanations of why this happened. The grout may have been washed too soon or too much during the cleaning process, causing pigment to be removed from the grout. Or, the grout powder may not have been dry-blended before mixing in order to avoid color variation.
