Quikrete 866010 Gray Polyurethane Sealant 10.1 Oz

Product Description

The QUIKRETE COMPANIES 866010 is a construction-grade, self-leveling polyurethane sealant supplied in a 10.1-ounce tube. It is formulated for sealing cracks and expansion joints in horizontal concrete surfaces where gravity can be used to aid leveling. The self-leveling formula flows into irregular voids and cures to a flexible, durable seal that resists movement from thermal cycling and structural settling. Licensed contractors and experienced DIYers working on concrete flatwork rely on this product to protect joints from water infiltration and debris intrusion.

This sealant is intended for horizontal concrete applications in residential and light commercial settings. Typical use cases include expansion joints in concrete slabs, cracks in concrete floors, driveways, patios, steps, basements, and pool decks. Because the formula is self-leveling, it is not suited for vertical or overhead surfaces without additional support. It is sold in a package quantity of 6 tubes per case.

Key Features

• Self-leveling formula flows into cracks and joints without tooling on horizontal surfaces
• Polyurethane chemistry provides superior adhesion to concrete substrates
• Flexible cure accommodates joint movement from thermal expansion and contraction
• Construction-grade durability suitable for driveways, patios, pool decks, and basement floors
• Standard 10.1-ounce tube fits common caulk guns used in the trade

Compatibility

Designed for use on horizontal concrete surfaces including expansion joints in slabs, cracks in concrete floors, driveways, patios, steps, basements, and pool decks.

Installation Notes

Surface preparation is critical — concrete must be clean, dry, and free of dust, oil, and loose material before application. A licensed contractor or experienced tradesperson should ensure joint width and depth are within the product's intended range before dispensing. Follow local building codes for joint sealant specifications on flatwork and pool deck applications. Do not apply to vertical or overhead surfaces, and keep the product away from open flame during installation.
