Quikrete Companies 866011 Polyurethane Non-sag Sealant 10.1 Oz

Product Description

The QUIKRETE COMPANIES 866011 is a construction-grade polyurethane non-sag sealant packaged in a 10.1 oz tube. It is formulated specifically for vertical and overhead surfaces where a standard sag-prone sealant would fail to stay in place. The non-sag formula delivers strong adhesion and flexibility, making it suitable for sealing expansion joints, cracks, and openings in concrete, stucco, and masonry assemblies. Licensed contractors and experienced tradespeople apply this product wherever a durable, flexible seal is needed on surfaces that are not horizontal. The polyurethane base resists movement and weathering over time.

This sealant is designed for use on exterior and interior construction surfaces including concrete wall panels, stucco walls, and masonry. Common applications include sealing expansion joints in concrete and stucco, sealing around window and door openings, and filling cracks in concrete and masonry surfaces. The non-sag characteristic makes it practical for overhead work and vertical joints where the material must hold position while curing. It is a standard tool for concrete and masonry contractors, general contractors, and restoration crews working on commercial or residential structures.

Installation Notes
