Frequently Asked Questions (FAQ)

No, this grout requires no sealer and cures naturally from evaporation of the low level of water in the formulation; in any event, sealants do not adhere well to Flexcolor CQ grout, due to its formulation.

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 UltraCare Grout MAXimizer, a water-based additive for grout that fortifies the flexibility and stain resistance of the grout.

Yes, you can apply Flexcolor CQ grout over existing Flexcolor CQ grout on deeper grout joints. The key is to leave only a thin layer on the joint surface. For details, see our “Grout Troubleshooting Guide.”

Yes, on deeper grout joints, you can re-apply Kerapoxy grout over an existing layer of Kerapoxy grout (or Kerapoxy CQ over Kerapoxy CQ). The key is to leave only a thin layer on the joint surface.

No, a cement-based grout needs 2/3 the thickness of the tile for proper placement. Scrape it away and re-grout any grout joints with this condition.

Excess moisture in a plywood or wood substrate is a probably just as damaging to a floor installation as high moisture content in a concrete slab. According to industry standards, the moisture content of a plywood substrate should be in the range of 10% to 15%. Dryer than that risks extreme adhesive absorption and subsequently poor adhesive transfer to the flooring. Wetter than that (such as through exposure to rain before installation) and the adhesives will take longer to dry; then when you have installed the flooring and the plywood has dried out, you will see the result of the plywood panel shrinkage through the surface of the flooring. A critical success factor for any floor installation is to make sure that the substrate you are working on is stable and acclimated to the working environment. Anytime you step outside that playing field, you will find yourself in trouble.

Although not required, for optimal results, Ultracolor­ Plus FA or Ultracolor Plus Max may be sealed - especially in places such as showers. Sealers make grout maintenance easier in the long run. The solution: UltraCare Grout Sealer.

You can use our UltraCare Acidic Tile & Grout Cleaner.

A thin layer of residue, or grout haze, left on the tile surface can usually be removed with a dry cloth. If it is more stubborn to remove, use the appropriate UltraCare product recommended in our technical document: “Removing Grout Haze.”

There are a few great reasons why applying a flooring adhesive with a paint roller is a good idea. The first, and probably the most obvious, is that you get to apply the flooring adhesive from a standing position. It's no longer necessary to crawl across the floor on your hands and knees when you can stand up and apply using a roller. Another advantage is that your coverage will increase on a per-gallon basis. Roller-applied adhesives typically are applied rather thinly, which extends the coverage by as much as 50% – a real savings on a per-square-foot basis. Yet another advantage to applying adhesive with a roller is that the drying time is much faster than with traditional trowel applications. Being that it is applied in a thin coat, the adhesive flashes off quickly, allowing for flooring installation much faster than with traditional methods.
