Quikrete Companies 8620-17 Concrete Crack Sealant 10 Oz

Product Description

The QUIKRETE COMPANIES 8620-17 is a polyurethane concrete crack sealant formulated for construction-grade waterproofing and sealing applications. Packaged in a 10 oz tube, it delivers a textured, non-sag formula that dries to a firm, flexible consistency. This sealant is suited for both vertical and horizontal surfaces, making it a versatile option for repair work on concrete, masonry, and stucco. Licensed contractors and experienced tradeworkers use it to stop water infiltration at cracks before they propagate or allow moisture damage to structural surfaces.

This sealant is designed for use on concrete flatwork, foundation walls, masonry block, and stucco exteriors in residential and light commercial construction. The non-sag characteristic makes it especially practical on vertical surfaces such as foundation walls and retaining structures where runoff or slumping would compromise the seal. It fits standard caulk guns for controlled application in tight or irregular crack profiles.

Key Features

• Polyurethane construction-grade formula provides durable, flexible crack sealing
• Non-sag consistency holds position on vertical and horizontal surfaces
• Waterproofing performance seals cracks against moisture infiltration
• Textured finish blends with concrete, masonry, and stucco surfaces

Installation Notes

Application is typically performed by masonry contractors, general contractors, or experienced maintenance technicians familiar with surface preparation requirements. Clean the crack of loose debris, dust, and standing moisture before applying the sealant. Follow manufacturer cure time guidance before exposing the sealed area to water or traffic loads. Consult applicable building codes for structural crack repair requirements on load-bearing assemblies.
