SURFACE PREPARATION
New surface
Let the concrete, cement plaster and mortar must be cured at least 28 days in ambient condition (average temperature is 25°C -30°C, relative humidity <75%), the surface moisture is not exceed 16% (specialized measuring testing equipment). pH value is about 6-9.
Remove all dust, grease, wax, laitance, chalking and others contamination from the surface by specialized machine as: grinding, sanding, vacuum cleaner, high pressure water jet and proper cleanness.
Old surface
Remove all dust, fungus, algae, loose old paint or others contamination from the surface by specialized machine as: grinding, sanding, vacuum cleaner, high pressure water jet and proper cleanness.
Then, treat the areas attacked by fungus, algae with proper chemicals.
Wash the surface if required, let it fully dry, the substrate moisture must be lower than 16% (specialized measuring testing equipment).
Repair the damaged area. Cracks bigger than 0.1mm must be fixed and make smooth by plasters.
The surface must be hard, firm before application.
APPLICATION
Reference application:
1. Use a high pressure "hopper" spray gun, spray a thin layer spread over the entire surface at the rate of approx. 2.0 kg/m2. Application area should be divided into several appropriate small areas to avoid difference in the finished patterns
2. Then reduce the pressure and spray a thin layer to create arbitrary patterns at the rate of approx. 1.0 kg/m2. Specialized tools such as trowel, etc. could be used to create special patterns.
3. Allow the paint film to dry for at least 24 -48 hours before spraying with TOA DECOR CLEARCOAT
