Application
General Preparation considerations for all surfaces
The key to optimum performance with Keim products is preparation prior to decoration.
- Remove flaking and unstable material back to a sound edge.
- Check that any remaining coatings are stable and feather the edges with sand paper.
- Flat down any shiny surfaces with sandpaper to create a good key
- Remove any Mould and Fungal growth and treat the affected area with Keim Algicid.
- Repair cracks with Keim Spachtel filler
- Ensure air and surface temperatures are between 5-30ºC
Clean all surfaces with clean cold water to remove dirt, dust and contaminants. Leave surfaces to dry naturally.
