Construction description


Construction condition:

Coating substrate temperature: Minimum 5℃maximum of 45℃

Relative humidity below 90%, the substrate surface temperature above the dew point temperature above 3 degrees, temperature and humidity should be measured near the substrate.

Outdoor painting is not allowed in rainy, snowy, foggy or strongly windy days

Construction method: Using single spraying equipment or brush coating

 


Non gas sprayingbrush coating
Spray pressure8~12MPa
Nozzle diameter525


Spraying pressure and nozzle size may be adjusted according to appropriate requirements of painting performance.

Tool cleaning: Methyl ethyl ketone

Surface treatment: After the concrete be completely dryd (newly prepared concrete should be cured for 28 days), the surface should be sanding or shot blasted to remove loose impurities on the surface. Old concrete is used to repair the holes and cracks with putty.
