Sikagard®-703 GroutSeal

A ready-to-use, low viscosity silane/siloxane water repellent impregnation in aqueous phase. Deeply penetrates tile joints, concrete, and building surfaces to provide strong water resistance without changing the substrate appearance. Reduces dirt pick-up and inhibits fungal and algal growth. Water-based and environmentally friendly.

  • Protection: Protect the treated surface from rain for at least 3 hours at +20°C after application.
  • Overcoating: Can be overcoated with water or solvent-based polymer paints – contact the paint manufacturer for compatibility details. For Sikagard® polymer paint, wait at least 5 hours before applying.
  • Cleaning: Clean all tools and equipment with water immediately after use. Hardened or cured material can only be removed mechanically.
