Any area affected by mould, algae, lichen, moss and fungus shall be treated with TOA Micro Kill. Make good any surface imperfection with suitable weather resistant putty or sealant. Ensure surface is dry, clean, and free from dirt, grease or wax prior to application of paint. Porous surface with high absorption should first prime with Wallsila 800 or Wallsila 900 sealers.
