What preparation steps are different when applying adhesive with a roller?

Before applying adhesive with a roller, it is crucial to ensure that the substrate is extremely clean. When you are standing to apply the adhesive with a roller, you may not see grains of dirt or other debris that you might otherwise would have noticed with a trowel application. It is always a good idea to vacuum the floor with a high-quality vacuum system before application. In addition, make sure that your floor is flat (as opposed to smooth). Roller-applied adhesives go down very thinly, so any substrate defect left on the floor is probably going to show through. We recommend using a MAPEI self-leveling compound before installing Ultrabond ECO 379 to ensure a flat, porous substrate on which to work.

What substrates can Mapecoat TNS systems be installed on?

Mapecoat TNS systems can be installed on new or existing asphalt or concrete slabs. On fresh concrete, a layer of Mapecoat TNS Primer EPW is applied first to provide excellent adhesion under the selected hard or cushioned system. For existing slabs with cracking, either the Mapecoat TNS Reinforced or Mapecoat TNS Comfort Elite system can be used to prevent non-structural cracks from coming through the new surface.

Which is better, a water-based or solvent-based sealer?

In today’s world, we have water-based technology that is equal to, or better than, solvent-based products. Because of their unique molecular construction, MAPEI’s UltraCare Penetrating Plus Stone, Tile & Grout Sealer and UltraCare Penetrating Plus SB Stone & Porcelain Tile Sealer are formulated for use on both porous and dense surfaces.

Why did my grout dry lighter than the color I purchased?

There can be different explanations of why this happened. The grout may have been washed too soon or too much during the cleaning process, causing pigment to be removed from the grout. Or, the grout powder may not have been dry-blended before mixing in order to avoid color variation.

Why does Ultracolor Plus FA sometimes bleed and come out when I rub my finger on it?

This indicates that too much water may have been used either in the mix or the cleaning process.
