Sakrete 65450009 Polyurethane Non-sag Caulk 10.3 Oz

Product Description

The SAKRETE OF NORTH AMERICA 65450009 is a single-component polyurethane non-sag sealant caulk packaged in a 10.3 oz tube. It forms a flexible, durable joint with strong adhesion to concrete and masonry substrates. The non-sag formula holds position on vertical and overhead surfaces without slumping, making it the right choice for repairs that cannot be done flat. Contractors and trade professionals use it to seal and repair cracks in concrete and masonry as part of routine maintenance or restoration work.

This sealant is designed for use on concrete walks, driveways, foundations, and steps, as well as masonry block and brick surfaces. Its non-sag characteristic makes it particularly suited for vertical joints, overhead seams, and any surface orientation where a standard sag-prone caulk would fail to stay in place before curing. It is appropriate for both residential and light commercial applications where flexible crack repair is required.

Key Features

• Single-component polyurethane formula — no mixing required
• Non-sag consistency holds on vertical and overhead surfaces
• Forms a flexible joint to accommodate minor substrate movement
• Excellent adhesion to concrete, masonry block, and brick
• Suitable for walks, driveways, foundations, steps, and masonry repairs

Compatibility

Designed as a direct-application sealant for concrete and masonry substrates including poured concrete, masonry block, and brick. Suitable for exterior crack and joint repair on horizontal, vertical, and overhead surfaces.

Installation Notes

Application is typically performed by a mason, concrete contractor, or qualified tradesperson. The substrate should be clean, dry, and free of loose material before applying the sealant. Cut the tube nozzle to the desired bead width and apply using a standard caulk gun with steady, consistent pressure. Follow all applicable local building codes and the manufacturer cure time guidelines before exposing the repair to water or traffic.
