Tamoseal Waterproofing Finish for Long-Lasting Protection
Tamoseal waterproofing finish is a cement-based, polymer-modified coating engineered to waterproof and decorate concrete and masonry surfaces. When combined with AKKRO-7T or FLEX-CON acrylic admixture, it forms a tenacious bond that becomes an integral part of the substrate, creating a durable barrier for both vertical and light-duty horizontal surfaces. Its breathable formulation helps control moisture while allowing the structure to release trapped vapor, ensuring long-term stability and protection.
