What colors are available for 2-1/2 to 1?

MAPEI's 2-1/2 to 1 professional Saltillo tile grout is only available in the color gray.

Can I use 2-1/2 to 1 to regrout over old grout?

Cement-based grouts like MAPEI's 2-1/2 to 1 grout won’t effectively bond to themselves. So if the existing grout is damaged, then at least 2/3 of the depth of the grout joint must be removed before regrouting. Note: If the existing grout is simply discolored, MAPEI’s UltraCare™ Grout Refresh™ can restore the look without removal of the existing grout.

Can 2-1/2 to 1 be mixed with an additive?

Additives are not recommended with MAPEI's 2-1/2 to 1 grout.

What is the proper way to mix a cement-based grout?

Be sure to follow the packaging instructions carefully when mixing. Keep the water-to-powder mixing ratios correct and adhere to the mixing and resting times. Use a drill rather than mixing by hand. Do not add more water if the product begins to thicken.

Does 2-1/2 to 1 need to be sealed?

MAPEI's 2-1/2 to 1 is a cement-based grout and is porous. Therefore, it will absorb stains and should be sealed. Sealing 2-1/2 to 1 grout will help to maintain it, keep it clean and minimize discoloration. Choose a high-quality grout sealer.

How soon can 2-1/2 to 1 be sealed?

Wait at least 5 days before applying a sealer over MAPEI's 2-1/2 to 1 grout.
