All-Purpose Primer for Self-Leveling Underlayments
Primer T is a low-VOC, water-based acrylic primer that enhances the performance and adhesion of self-leveling underlayments (SLUs) on nonabsorbent surfaces such as ceramic tile, vinyl composition tile (VCT), epoxy moisture barriers and adhesive residue, as well as profiled, absorbent surfaces. Suitable for a wide variety of substrates, Primer T combines excellent versatility with an easy, low-odor application.
Should I use Primer T™ at full strength?
When using MAPEI's Primer T over plywood, cement board and smooth concrete, or existing flooring such as ceramic tile, porcelain tile, natural stone and VCT, apply Primer T at full strength (do not add any water). Primer T should also be used at full strength between multiple layers of MAPEI's Ultraplan® 1 Plus.
