OTTO Siloxane 290L

• Hydrophobization of facades and building elements made of concrete, aerated concrete, fiber cement, masonry, sand-lime brick, natural and artificial stones, mineral plaster and paint layers
• Drying damp and cracked surfaces, which can then be painted over with dispersion paint
• Only for vertical surfaces

• Ready-to-use silicone surfaces hydrophobization
• High penetration depth
• UV resistant
• Can also be used on damp surfaces (not rain wet)
• Forms a water and dirt-repellent surface
• The hydrophobic effect prevents moisture from entering from the outside, but allows moisture from the inside to escape.
• Bridges hairline cracks up to 0.3 mm wide
• Reduces the tendency to soil the treated surfaces
• Prevents the building material from becoming thoroughly damp and thus salt efflorescence, as well as damage by moss and algae
• Can be painted over with commercially available dispersion paints
• Low odor
• Colourless
• Color may darken slightly
