NC 888 MT PREMIUM PLUS – Moisture Tolerant Turbo Patching Compound

Polymer-modified portland-based fine smoothing compound

Moisture-tolerant, rapid-drying, fine repair mortar used to smooth and fill imperfections on interior surfaces before installing floor covering materials. When mixed with water, this polymer-modified compound of Portland and select hydraulic cement can be applied to various surfaces, often without the need for a primer. It is suitable for use with all floor coverings and adhesives.

Applications

Interior use only
Use over concrete substrates without an RH% limit
Use over cement-based leveling compounds
Use over wood, plywood, OSB, and underlayment panels
Use over well-bonded adhesive residues, including cutback adhesive*
