Sealing Ultracolor Plus FA by Mapei
Hey Coach,
From the Mapei site-
Although MAPEI's Ultracolor Plus FA grout does not require a sealer, it can be sealed. Select a high-performance, penetrating grout sealer, such as ourUltraCare® Penetrating Plus SB Stone & Porcelain Tile Sealer.

Sealer will make it easier to keep clean. In order to perform at its best, it will need to be reapplied every year no matter what they say on the bottle. At least or the first 3-4 years or so.
