Thermo-Shield® Interior Wall Coats are high-performance, water-based acrylic coatings designed to waterproof interior walls while improving durability, comfort, and safety. Formulated with vacuum ceramic microsphere technology, they create a seamless, flexible membrane that bridges hairline cracks and provides thermal and sound insulation.
These non-toxic, low-VOC coatings are fully washable, resist chemicals and dirt pickup, reduce condensation, and help maintain even temperatures from floor to ceiling. With excellent fire resistance and very low smoke development, Thermo-Shield® Interior Wall Coats are ideal for residential, commercial, and institutional interiors. Available in a range of architectural colours with a smooth matte finish.
