FAQs
Should I use a sanded grout like Keracolor S?
Sanded grouts like MAPEI's Keracolor S grout are generally recommended for grout joints 1/8" and larger. Because sanded grouts contain sand, they typically don't work well in grout joints smaller than 1/8" wide. Keracolor S should always be tested in an inconspicuous area before grouting.
Can Keracolor S be used in joints 1/8" or smaller?
MAPEI's Keracolor S contains sand. So, when it is used for joints narrower than 1/8", it will be difficult to pack the grout fully into the joint. This often results in voids below the surface of the grout, which turn into areas of missing grout over time. It is best to use MAPEI's Keracolor® U, Ultracolor® Plus FA or MAPEI Flexcolor® CQ grout for joints less than 1/8" wide.
Can I use Keracolor S with installations of natural stone?
MAPEI's Keracolor S grout contains sand. So, it is generally not recommended with installations of polished stone tile. If grouting honed or tumbled stone, it is recommended to build a mockup (sample board) or, at the very least, test Keracolor S in an inconspicuous area before grouting.
Can Keracolor S be used to grout unfilled travertine and limestone tile?
It is best to use MAPEI's Keracolor U grout or MAPEI Flexcolor® CQ grout when grouting unfilled travertine tile.
Can Keracolor S be used to grout pebble tile?
It is best to use MAPEI's Ultracolor® Plus FA grout when grouting pebble stone and river rock mosaics.
Can I use Keracolor S with installations of glass tile?
MAPEI's Keracolor S grout contains sand and may scratch glass surfaces. It is best to use Keracolor® U grout for glass tile and delicate glass tile. If a sanded appearance is desired, a colored-quartz (CQ) grout such as MAPEI Flexcolor® CQ can sometimes be used successfully, but a test panel should be grouted and inspected for unacceptable scratching before grouting.
Can I use Keracolor S with glossy wall tile?
MAPEI's Keracolor S grout contains sand and may scratch delicate finishes. It is best to use Keracolor® U grout for glossy wall tile. If a sanded appearance is desired, a colored-quartz (CQ) grout such as MAPEI Flexcolor® CQ can sometimes be used successfully, but a test panel should be grouted and inspected for unacceptable scratching before grouting.
Is Keracolor S recommended with wood-look tile?
It is best to use MAPEI's Ultracolor® Plus FA grout or MAPEI Flexcolor® CQ grout for grouting installations of wood-look plank tile.
Can Keracolor S be used in a pool?
MAPEI's Keracolor S grout can be used in submerged applications such as pools, but a 21-day curing time is required before filling the pool. MAPEI’s Ultracolor® Plus FA grout is a better choice for pool installations.
Can I use Keracolor S to regrout over old grout?
Cement-based grouts like MAPEI's Keracolor S 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 Keracolor S be mixed with an additive?
MAPEI's Keracolor S grout can be mixed with MAPEI’s UltraCare™ Grout Maximizer. • One 10 lbs. of Keracolor S grout requires 26 U.S. oz. of UltraCare Grout Maximizer. • One 25 lbs. of Keracolor S grout requires 64 U.S. oz. of UltraCare Grout Maximizer.
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 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. If using a grout additive such as MAPEI's UltraCare™ Grout Maximizer, keep the correct ratios of liquid additive to grout powder, do not add water, and adhere to the mixing and resting times. Use a drill rather than mixing by hand. Do not add more liquid additive or add water if the product begins to thicken.
Do I have to mix the entire bag of Keracolor S grout at once?
If preferred, MAPEI's Keracolor S grout can be mixed in small amounts. First, dry-blend the grout, because color pigments can settle to the bottom of the bag during shipping. Then, mix 1 U.S. cup of water to 4 U.S. cups of grout powder.
Does Keracolor S need to be sealed?
MAPEI's Keracolor S is a cement-based grout and is porous. Therefore, it will absorb stains and should be sealed. Sealing Keracolor S grout will help to maintain it, keep it clean and minimize discoloration. Choose a high-quality grout sealer.
How long until Keracolor S can be sealed?
Wait at least 5 days before applying a sealer over MAPEI's Keracolor S grout.
