Intended Use
Hydro Stop Siloxane Water Repellent Impregnation by BAYRIS is designed for the surface hydrophobisation of substrates to provide a durable water-repellent finish. Suitable for application on concrete, brick, natural sandstone, mineral renders and other porous substrates. It can also be used to improve the water-repellent properties of emulsion paints and acrylic renders. Recommended for the treatment of sculptures, façades, stone structures, slate, clay products and aerated concrete. The product is less suitable for low-absorbency, dense natural stone surfaces, particularly limestone and marble. Suitable for both interior and exterior use.
Characteristics
Hydro Stop Water Repellent Impregnation is a ready-to-use product with no strong odour and no toxic substances. It penetrates deeply into the substrate and creates a hydrophobic barrier that effectively repels water and provides a self-cleaning effect. It helps prevent efflorescence and surface contamination, while reducing the risk of fungal and mould growth. It improves frost resistance, does not form a film and does not create a glossy finish.
Surface Preparation
Prepare the substrate in accordance with applicable construction standards and best practice. The surface must be visibly clean, dry and free from loose material. If necessary, remove dirt, dust, grease, biological contamination and other impurities.
Application
Apply when the substrate and ambient temperature are between +8°C and +30°C (avoiding direct sunlight) and relative humidity is between 50% and 80%. Do not dilute with water. Stir thoroughly before use. Apply evenly in a continuous “wet-on-wet” method using a brush, roller, masonry brush or spray equipment, following the recommended coverage rates. Clean tools with water immediately after use.
Warning! Any modification of the product, use for purposes other than those intended and/or failure to follow the manufacturer’s instructions may significantly affect product performance. The suitability of the product for specific materials and/or compatibility with other materials must be determined by the user through testing. The manufacturer accepts no liability for direct or indirect losses resulting from product use, as it is not possible to control all application conditions.
Coverage
Approximately 0.15–0.3 L/m² per coat depending on the type of surface and its absorbency.
Safety and Disposal
Avoid direct contact with skin and eyes. In case of contact, rinse thoroughly with plenty of water. Seek medical advice if necessary. Construction waste must not be disposed of in general household waste containers. Dispose of waste materials in accordance with local regulations. Empty containers and liquid residues should be taken to authorised hazardous waste collection facilities.
VOC Content
The VOC content of Hydro Stop Siloxane Water Repellent Impregnation by BAYRIS complies with the requirements for VOC emission limits for primers, maximum 30 g/L. The actual VOC content of the ready-to-use product does not exceed 9 g/L.
