UltraCare Grout Maximizer is not a sealer. It is a polymer additive that is formulated specifically for use in standard cement-based grout mixtures to fortify the grout and help resist staining that is caused by water-borne contaminants. To learn more about MAPEI sealers, watch the video below.
Cement-based grouts have been around for decades and are very reliable, but are also the most porous and stain-susceptible of all the grouts. Instead of using just plain water to mix the grout, use MAPEI’s UltraCare Grout Maximizer, a water-based additive for grout that fortifies the flexibility and stain resistance of the grout.
