SURFACE PREPARATION
New surface
Let the concrete, cement plaster and mortar must be cured at least 28 days in ambient conditions (average temperature is 25°C -30°C, relative humidity is under <75%), the surface moisture is not exceeded 16% (specialized measuring testing equipment). pH value is about 6-9.
Remove all dust, grease, wax, laitance, chalking and other contaminants from the surface by specialized machine as: grinding, sanding, vacuum cleaner, high pressure water jet and proper cleaning.
Apply 2 coats TOA PRO PUTTY or SUPERTECH PRO PUTTY INTERIOR for smooth surface.
Old surface
Remove all dust, fungus, algae, old loose paint or other contaminants from the surface by specialized machine as: grinding, sanding, vacuum cleaner, high pressure water jet and proper cleaning.
Then, treat the areas attacked by fungus or algae with proper chemicals.
Wash the surface if required, and let it fully dry, the substrate moisture must be less than 16% (specialized measuring testing equipment).
Repair the damaged area. Cracks greater than 0.1mm must be fixed and make smooth by TOA Pro Putty or Supertech Pro Putty interior.
Apply 1 coat of premium multipurpose primer - TOA HYDRO QUICK PRIMER for chalky or powdery surfaces after making the surface clean.
APPLICATION METHOD
Film thickness:
