OTTO Siloxan 290L


Surface water-repellent product

OTTO Siloxan 290L - The silicone for surface impregnation. Characteristics: • Ready-to-use silicone surface impregnation • High penetration depth • UV-resistant • Can also be applied on moist substrates (not rain-wet) • Forms a water- and dirtrepelling surface • The hydrophobe effect prevents the penetration of moisture from the outside to the inside but it lets the internal moisture escape to the outside • Bridges hair cracks up to a width of 0.3 mm • Reduces the tendency of treated surfaces to pick up dirt • Avoids humidity in the construction material thus avoids salt efflorescence as well as moss and algae growth • Paintable with commercial dispersion paints • Low odour • Colourless • Slight deepening of colour is possible. Fields of application: • Hydrophobic treatment of façades and building components made of concrete, cellular concrete, fibre cement, brickwork, natural and artificial stone, mineralic plasters and coatings • Drainage of moist and cracked surfaces, which are then painted using dispersion paints • Only for vertical surfaces.
