Description
JAYCOCRETE STANDARD is a synthetic rubber latex admixture formulated for use with cement and cementitious mixtures. It significantly enhances adhesion, flexural strength, and water resistance in mortars, screeds, renders, and repair compounds. When mixed with cement, it forms a tough, flexible film that improves durability and reduces cracking. The product is ideal for waterproof bonding, patch repairs, and floor toppings where superior adhesion and flexibility are required.
