Step 1 - Surface Preparation:
- New surface:
+ Let the surface dry after 28 days in normal condition (average temperature is 25°C -30°C, relative humidity under 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 other contamination from the surface by specialized machine as: grinding, sanding, vacuum cleaner, high pressure water jet and proper cleanness.
+ Apply 2 coats TOA PRO PUTTY for smooth surface.
- Old surface:
+ Remove all dust, contamination, loose old paint from the surface by specialized machine as: Grinding, sanding, vacuum cleaner, high pressure water jet and proper cleanness. Treat the area 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 smoothed by TOA PRO PUTTY.
+ Apply 1 coat of TOA HYDRO QUICK PRIMER - Premium multipurpose primer for chalky or powdery surface after making surface clean.
Step 2 - Sealer: Apply 1 coat of SuperShield Super Sealer.
Step 3 - Topcoat: Apply 2 coats of TOA 7in1, SuperShield or SuperShield DuraClean A+.
* Note: Stir well before use and once opened, entire content should be used. Apply when temperature is from 10°C to 35°C and relative humidity under 75%.
