Slab combines the durability, flexibility, and adhesion you need for lasting concrete crack repairs. This easy-to-apply, 100% acrylic latex water-based product is textured to simulate concrete so repairs blend in. Plus, Slab contains no isocyanates or solvents, which means it is easy on your nose and on your planet.
