Will UltraCare Grout Refresh stick to dirty grout?

It's important for the existing grout to be porous and completely clean before applying MAPEI's UltraCare Grout Refresh. So the first step is to clean the existing grout using a heavy-duty, tile and grout cleaner. Next, test the porosity of the grout with a few drops of water. If the grout does not absorb the water drops within a few minutes, this indicates that the grout was probably sealed. Note: UltraCare Grout Refresh will not bond to sealed grout.

Will UltraCare Grout Refresh stick to sealed grout?

In order for MAPEI's UltraCare Grout Refresh to bond effectively, all sealers on the existing grout must be removed. MAPEI recommends contacting the sealer manufacturer for removal instructions.

Can I use UltraCare Grout Refresh if my grout was mixed with an additive?

If the existing cement-based grout was mixed with an additive such as MAPEI’s UltraCare Grout Refresh, the grout should be scrubbed clean using a grout brush and an acid-based, heavy-duty tile and grout cleaner. Follow all directions for the cleaner, neutralize the grout area with water and allow it to dry completely before the application of MAPEI's UltraCare Grout Refresh. Note: Do not use acid-based cleaners with installations of natural stone.

Can I put UltraCare Grout Refresh on ready-to-use (pre-mixed) grouts?
