Grout Renew is a waterborne acrylic stain and sealer for renewing or changing the color of cement grout joints. Formulated with fade-resistant pigments, Grout Renew seals the grout against stains while it colors. Available in all 40 Polyblend® Plus colors to complement any tile or stone installation.
Instead, use UltraCare Grout Refresh, a water-based colorant and sealer that is available in MAPEI's full palette of grout colors. UltraCare Grout Refresh is made for refreshing the look of old, discolored grout or completely changing the color of the existing grout.
Yes new grout can be installed on old grout. Make sure the old grout is thoroughly cleaned and then wet before installation. I do this all the time. There is absolutely no need to start over and given the quality of the install you have had so far I would say that starting over might introduce more issues.
Unglazed tile will require sealing prior to coloring to ensure Grout Renew isn't absorbed into the tile. We recommend TileLab® SurfaceGard® Sealer. Do not apply when ambient temperature is below 50°F (10°C) or above 80°F (27°C).

Moisture can penetrate the grout, causing it to expand and contract, leading to cracks and gaps between tiles. These openings not only look unsightly but can also allow further moisture intrusion, potentially leading to structural damage to the underlying substrate.
When mixing the grout together, you want to use an additive instead of water. This will ensure that the grout is stronger and more consistent in color.
There are two ways you can change the colour of your grout. You can either remove the old and replace it with new, or you can dye your existing grout. The latter will only work if you currently have light grout and you want to dye it darker.
You can use either cold or warm water to rinse, but cover the scrubbing area thoroughly to ensure you end up with clean tile grout.
Do You Regrout or Retile? The average cost of tiling a shower is about $1,800–$5,000. Retiling a shower will be a few hundred dollars more once you factor in $2–$5 per square foot to remove the old tiles. Regrouting shower tiles costs significantly less, with an average price range of $700–$1,500.
Before you decide to regrout, evaluate the state of the existing grout. If it's severely damaged, crumbling, or has mold, it may be necessary to remove it entirely.
Choosing the correct grout is a basic step in the process of regrouting over existing grout. The most common grout types are cementitious (which is unsanded or sanded) or epoxy (which is also sanded or unsanded).
Carefully apply to the grout joint and allow to dry 30-60 minutes. Work small areas at a time. Ready for light traffic in 2 to 4 hours, normal traffic in 24 hours. Do not expose to water for 72 hours.
Baking powder is actually a tried-and-true way to clean bathroom grout. First, mix some baking powder with water to create a thick paste. Then apply this paste to the grout and let it sit for about an hour. The grout can then be rinsed with clean water and any reside that remains can be wiped away with a cloth.
Final Verdict. Our favorite grout cleaner is the Black Diamond Ultimate Grout Cleaner Spray for Tile with Brush. It can be used to lift various household messes and stains on many surface types. We also love that it comes with a firm-bristled scrub brush.
Grout pens will only temporarily cover your grout's discoloration. That's probably why they are the cheapest option available. We run into the infamous grout pen issue nearly every other week. The project usually goes awry when the homeowner applies the grout pen to the grout and some bleeds over onto the tile.
Replacing grout is certainly one way to fix the problem. Instead, use UltraCare Grout Refresh, a water-based color seal, available in 40 standard grout colors. It's made for refreshing the look of old, discolored grout, or completely changing the color of the existing grout.
Waiting too long to wipe grout could result in unsightly grout haze. Don't wait too long to wipe off grout!
Whoever installed your floors most likely did not seal the grout because it needs time to harden and cure completely.
Remember the tip on avoiding bleach, ammonia, and other harsh chemicals to clean grout. It would be best if you also avoided vigorous scrubbing. A rough brush and too much elbow grease will remove the dirt, but it could also remove the grout. Another way to prevent grout damage is to use a squeegee on shower walls.
The average cost to regrout a shower ranges between $900 and $2,500. Key factors that affect the cost include the shower's dimensions, the type of grout used—such as high-quality epoxy grout known for its mould and stain resistance—and the labor involved in removing the old grout.
Epoxy grout doesn't need to be sealed at all.
The shelf life of grout once opened is typically 6 months, but this will vary depending on the brand and how it is stored.
