Description

Advanced Protection Against Moisture

Protecta Waterproofer is a high-viscosity, silane-based impregnating cream designed for deep penetration into porous building materials. It enhances water resistance without affecting breathability, making it ideal for stone, concrete, and brick surfaces. The product prevents moisture ingress, protecting against efflorescence, frost damage, and pollutants.



Where It Can Be Used

  • Protecta EX Mortar
  • Plaster and other mortars
  • Porous concrete and concrete structures
  • Limestone, natural stone, and industrial bricks
  • Clinker facades and masonry



Limitations and Application Restrictions

This product should not be applied to non-porous materials such as polished marble, granite, or Belgian hard stone. It is unsuitable for submerged conditions or application over bitumen, synthetic resins, or acrylic-based coatings. Avoid applying on insulated surfaces, as damage may occur. If the product contacts an unsuitable surface, it must be removed immediately with cold water.



Application Instructions

Ensure surfaces are clean, dry, and free from contaminants before application. The product is applied in a single coat using a roller or brush, ensuring even coverage of at least 50 g/m². It penetrates the substrate within 30 minutes to several hours, depending on porosity. The milky-white cream dries clear without altering surface appearance. A test area is recommended to determine the correct application rate.



Health and Safety

Protecta Waterproofer is classified as an industrial-use product. Repeated exposure may cause skin dryness or cracking (EUH066). Avoid contact with skin and eyes. In case of skin exposure, wash immediately with soap and water. For eye contact, rinse with running water for 15 minutes and seek medical advice. The product contains hydrotreated hydrocarbons. Always store in original packaging in a cool, well-ventilated area.
