Patch / Repair / Smoothing Compound - UZIN NC 890 HYDROPATCH

High-performance portland-based fine smoothing compound

Formulated primarily to repair concrete substrates with up to 100% RH to fulfill today's higher moisture-resistant adhesive and floor covering requirements. UZIN NC 890 HYDROPATCH is also recommended to fill joints, cracks, and localized repair areas before using UZIN PE 460 and UZIN PE 414 TURBO moisture vapor retarder coatings. Mixed with water, this polymer-modified compound of portland and select hydraulic cement can be applied to various surfaces, often without the requirement of a primer. Suitable for use with all floor coverings and adhesives.
