Installation Instructions
- Step 1: make sure the wall surface is firm, clean, smooth, dry and free from dust or loose materials. The substrate moisture content should be below 9% and the pH value below 12.
- Step 2: mix the primer with clean water at a 1:1 ratio and stir thoroughly. apply evenly to the wall surface using a roller.
- Step 3: after approximately 2 hours, mix the primer with clean water at a 1:0.5 ratio and apply a second coat evenly. the original instructions recommend a two-coat application.
- Step 4: allow the primer to dry completely before wallpaper or wallcovering installation. surface drying takes approximately 1–2 hours, while complete drying takes approximately 4–24 hours at 25–30°C, depending on temperature, humidity and site conditions.
Application Conditions
