Application Steps
- Substrate Preparation: Surface must be clean, sound, and properly cured. Remove all loose materials with a wire brush. Iron and steel surfaces must be free of rust.
- Without Membrane: For porous substrates, apply primer coat diluted with 10% water (~0.3 kg/m²). Allow to dry >3 hours. Apply 2 coats of Sika® RainTite (~0.3 kg/m² each) by brush or roller.
- With Membrane: Apply primer if needed (~0.3 kg/m², diluted 10%). Allow to dry >3 hours. Apply 1st coat (0.8–1.0 kg/m²). Embed Sika® RainTite membrane into wet 1st coat, smooth out air pockets and creases. Overlap adjacent membrane min. 50 mm. Immediately apply 2nd coat (0.8–1.0 kg/m²) wet-on-wet to fully saturate membrane. When dry, apply final top coat (~0.4 kg/m²). Protect from rain until dry.
- Cleaning: Remove uncured material with water. Cured material can only be removed mechanically.
