SAKRETE Concrete Bonder & Fortifier is a high-solids acrylic liquid bonding agent designed to enhance the performance of concrete projects. This versatile product can be used straight from the bottle as a paint-on bonder to improve adhesion between new and existing concrete surfaces, or as a fortifier and admixture for mortar, cement, and sand mixes. When used as a concrete bonding agent or concrete acrylic fortifier, it increases tensile, flexural, and compressive strength, while also boosting resistance to water penetration and freeze/thaw cycles. SAKRETE Concrete Bonder & Fortifier helps reduce shrinkage, minimizes the need for wet curing, and strengthens the bond in unmodified concrete mortars, patches, and grouts. Ideal for both professional contractors and DIY enthusiasts, this 1 gal bottle offers a reliable solution for concrete repair, restoration, and new construction. Use this concrete strengthener to achieve durable, long-lasting results in your next project, whether you are fixing cracks, resurfacing, or enhancing the durability of your concrete surfaces.
