The product can be used on natural and artificial stone, concrete, aerated concrete, sand-lime brick, brickwork, unglazed pottery, fiber cement, mineral plasters, and mineral paint coatings. The decisive technical point is its function as an impregnation, not as a sealant: The capillaries are not sealed but narrowed. This prevents water molecules from penetrating the substrate, while smaller water vapor molecules continue to escape from the stone. The building component remains diffusion-open, preventing damage from trapped moisture. SILOXAN W 290 hydrolyzes under atmospheric humidity and condenses into a non-tacky polysiloxane with very high penetration depth, extremely high alkali resistance, and high aging resistance. For businesses, this means slower weathering, prevented efflorescence, less mold, algae, and moss formation, and longer cleaning intervals on facades. Application is done by spraying, brushing, or dipping in at least two wet-on-wet coats, as effective hydrophobization is only achieved with substrate-saturating application.\u003c\/p\u003e\u003ch3\u003eYour Advantages at a Glance\u003c\/h3\u003e\u003cul\u003e\n\n\u003cli\u003eVery high penetration depth with substrate-saturating application\u003c\/li\u003e\n\n\u003cli\u003eExtremely high alkali resistance and high aging resistance\u003c\/li\u003e\n\n\u003cli\u003eNon-tacky drying without optical change\u003c\/li\u003e\n\n\u003cli\u003eDiffusion-open, narrows capillaries instead of sealing them\u003c\/li\u003e\n\n\u003cli\u003eAlso applicable on damp, absorbent substrates\u003c\/li\u003e\n\n\n\u003c\/ul\u003e\u003ch3\u003eProduct Application\u003c\/h3\u003e\u003cp\u003eApply SILOXAN W 290 by spraying, brushing, or dipping. Application must be done in at least two coats, working very generously and evenly wet-on-wet. Effective hydrophobization is only achieved with substrate-saturating application. Consumption depends on the absorbency of the substrate and is empirically between 100 and 250 milliliters per square meter, and in extreme cases even more. Sufficiently dimensioned test areas provide information about quantity and effect, especially on differently absorbent substrates such as shell limestone. Application on damp but absorbent substrates is possible. The product is harmful if swallowed and in contact with skin, can be fatal if swallowed and enters airways, and causes skin irritation. Ensure good ventilation, keep away from ignition sources, and wear personal protective equipment.\u003c\/p\u003e\u003ch3\u003eDosage\u003c\/h3\u003e\u003cp\u003eReady to use, do not dilute.

A 10-liter container thus covers approximately 40 to 100 square meters, a 30-liter container about 120 to 300 square meters. For highly absorbent substrates, the value can be significantly exceeded.\u003c\/p\u003e\u003ch3\u003eAreas of Application\u003c\/h3\u003e\u003cp\u003eNatural and artificial stone facades, exposed concrete and aerated concrete, sand-lime brick and brickwork, unglazed pottery, fiber cement panels, mineral plasters, and mineral paint coatings on buildings, monuments, retaining walls, and outdoor facilities.\u003c\/p\u003e\u003ch3\u003eMaterial Compatibility\u003c\/h3\u003e\u003cp\u003eSuitable for mineral, absorbent building materials of all kinds. Application on damp but absorbent substrates is possible. Do not use as a sealant and do not apply to non-absorbent or already densely coated substrates, as complete insulation by incorrect impregnation can destroy the substrate.
