Yes. In determining the quantities of mortar to order, it is important to know the added amount you will need for coverage with these membranes, and to make your calculations accordingly. Mapeheat™Membrane requires more mortar for coverage than Mapeguard® UM membrane, for example.
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.
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: UltraCareGrout Sealer.
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.”
