Polymer modified grout is a type of grout that has polymers added to its mixture to improve its properties. These polymers enhance the grout's adhesion strength, flexibility, and durability. This type of grout is often used in construction and repair work where better bonding and resistance to cracking or water are needed. It provides improved performance compared to traditional grout by reducing shrinkage and increasing resistance to chemicals and moisture. Polymer modified grout is suitable for both indoor and outdoor applications.
