MASTERSEAL® 303 

Clear Water Repellent Based on Alkyl Alkoxysilane for the Protection of Concrete Surfaces

MASTERSEAL® 303 is a single component clear, deeply penetrating water repellent used to protect both vertical and horizontal concrete surfaces from deterioration by atmospheric pollution, salt attack and freeze thaw cycles etc.

Features and Benefits

  • Provides a long-lasting protection: MASTERSEAL 303 penetrates deep into the surface acting as a water repellent that prevents water, salts (chloride ion), atmospheric pollution and freeze/thaw cycles from deteriorating the concrete
  • Improves the aesthetics by reducing efflorescence, algae growth and dirt build-up
  • Surface appearance remains unchanged
  • Reduces volatile organic emissions into the atmosphere in comparison with today’s commonly used organic-solvent-based repellents
  • Provides a safer working environment for the applicator by minimising health hazards associated with organic solvents
  • Ready for use; no dilution on site, which means constant quality
  • One coat, no primer
  • Masking window plate glass is not necessary before spray application
  • May be applied to damp substrates
  • Application equipment easily cleaned with soapy water
  • Virtually no product evaporates during spray application, therefore more active silane can reach its intended target, so minimising wastage and maximising coverage
