Sika Concrete Bonding Adhesive 1 gal.

Sika Concrete Bonding Adhesive is a high-performance, acrylic-polymer latex bonding agent designed to dramatically improve adhesion and durability in concrete and mortar applications. This milky white liquid can be used as a primer for bonding new concrete to old or as an admixture to fortify repair mortars. By substituting SikaLatex R for a portion of the mixing water, you’ll achieve a denser, tougher surface that resists freeze-thaw cycling and stands up to heavy traffic.

Ideal for both professional contractors and DIY enthusiasts, this versatile bonding adhesive ensures long-lasting, crack-resistant results on indoor and outdoor projects. Whether you’re repairing a driveway, overlaying a patio, or patching masonry, Sika Concrete Bonding Adhesive delivers consistent, reliable performance.
