Preparation of K-Rend Silicone TC15 Topcoat

  • A test panel to check colour and final appearance is recommended
  • Backgrounds should be clean, level, dry and free from efflorescence
  • Mask all adjacent surfaces including windows, sills, doors, timber, glass, brick & flooring
  • Protect weather exposed surfaces

Application of K-Rend Silicone TC15 Topcoat

  • The temperature of the substrate and surrounding air should be a minimum of 5oC
  • Do not apply in conditions of strong sunshine or wind; do not apply onto damp or frozen substrates
  • Allow freshly applied render basecoats a minimum of 14 days before work commences
  • Prime walls using Primer TC colour co-ordinated to topcoat and allow 24 hours drying time for primer before applying topcoat
  • Stir bucket contents thoroughly using a slow speed mixer. A small amount of water can be mixed with the product to achieve the best working consistency
  • Apply the product to the thickness of the largest grain size using a stainless steel float; allow to take up slightly.The surface is then rubbed up in a circular motion using a plastic float to create the texture
  • Complete continuous surfaces without interruption, working to a wet edge at all times
  • Drying times may be prolonged by lower temperatures and/or high humidity
  • The fresh render must be protected from rain and from drying too fast
