Mapei Antipluviol

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.

Key Benefits:

• Protects against heavy rain and aggressive atmospheric agents

• Preserves natural water vapour permeability

• Does not alter the appearance of the treated surface

• UV and alkali resistant for long-lasting protection

• Suitable for cementitious renders, cellular concrete, facing bricks, natural and artificial stone

Where to Use:

• External walls exposed to heavy rain

• Cement-based renders

• Cellular concrete

• Brick facades

• Natural and artificial stone surfaces
