High-Performance Silicone Water-Repellent for External Walls
Mapei Antipluviol is a high-performance, colourless silicone water-repellent designed to protect external walls from heavy rain while maintaining breathability and appearance. Unlike film-forming treatments, it penetrates deeply into pores and capillaries, creating a long-lasting hydrophobic barrier without altering the look or vapour permeability of the surface.
