BETOPROOF 4210
Water repellent and saturating
Colorless based on nano compounds
Description;
BETOPROOF 4210 is a single-component product based on nano-silicone compounds that, when applied to concrete and masonry surfaces, creates a water-resistant and water-repellent surface without altering the color. When combined with mortar or concrete, it provides impermeability and strong waterproofing properties.
Application areas:
- Suitable for surfaces with high slopes
- Waterproofing and protecting surfaces with high water absorption and infiltration, such as concrete, brick, lightweight concrete, tile, ceramic, natural and artificial stone, historical buildings, statues, and surfaces with mineral colors
- Not recommended for underground waterproofing with high pressure, galvanized surfaces, structures under hydrostatic pressure, and painted surfaces.
- Creating strong waterproof grouts for installing tiles, ceramics, and stones.
Colorless and does not create a film on the surface
Suitable for structures where no change in appearance should occur
Water-repellent effect
Allows the underlying surface to breathe
After application and treatment, there will be no color changes
Does not form a layer on the surface
Protects structures from dust, dirt, and the growth of fungi and algae
