Sakrete 60205002 Concrete Bonder Fortifier 1 Gallon

Product Description

The SAKRETE OF NORTH AMERICA 60205002 Concrete Bonder Fortifier is a liquid bonding agent and admixture formulated to significantly improve the performance of concrete, mortar, and plaster assemblies. Applied by brush as a bond coat or mixed directly into the batch as an admixture, it increases bond strength 8 to 10 times over untreated surfaces. The fortifier also improves adhesion, impact strength, abrasion resistance, and resistance to freeze-thaw damage. Each container holds 1 gallon and is intended for use by professional concrete and masonry tradespeople on both residential and commercial projects.

This product is designed for repair and resurfacing applications where new concrete, mortar, or plaster must bond to an existing substrate. Typical uses include patching spalled concrete flatwork, resurfacing slabs, bonding fresh mortar to cured masonry, and applying plaster coats over existing surfaces. It is suited for interior and exterior use and addresses common failure points such as delamination, surface wear, and cold-weather freeze-thaw cycling that weakens repair layers over time.

Key Features

• Increases bond strength 8 to 10 times compared to unbonded applications
• Dual-use formulation: apply as a brush-on bond coat or blend as an admixture into the mix
• Improves adhesion and impact strength at the substrate-to-repair interface
• Enhances abrasion resistance for high-traffic concrete and mortar surfaces
• Increases resistance to freeze-thaw damage in cold-climate installations
• Compatible with concrete, mortar, and plaster applications

Compatibility

Designed for use with concrete, mortar, and plaster mixes where bonding new material to existing cured substrates is required. Suitable for residential and commercial masonry and flatwork repair applications.

Installation Notes

Installation is typically performed by concrete finishers, masonry contractors, or experienced tradespeople familiar with surface preparation requirements. The existing substrate must be clean, sound, and free of dust, oil, and loose material before application. When used as a bond coat, allow the applied layer to become tacky before placing the new concrete or mortar. Follow all applicable building codes and manufacturer mixing instructions; do not apply to frozen surfaces or when ambient temperatures are expected to drop below freezing before the repair has cured.
