Construction parameters

Construction structure drawing:

Supporting scheme:
※ Polyurethane primer/epoxy zinc-rich primer/epoxy primer/inorganic zinc-rich primer/graphene zinc powder primer, etc. + polyurethane intermediate paint/epoxy cloud iron intermediate paint/epoxy thick paste intermediate paint + polyurethane topcoat
Construction precautions:
※ The temperature of the substrate must be above the dew point of 3℃, when the temperature of the substrate is below 5℃, the paint film is not solidified, and it is not suitable for construction.
※ In the high temperature season construction, easy to occur dry spray, in order

to avoid dry spray can be adjusted to dry spray until the diluent.
※ This product should be used by professional painting operators according to the product packaging or the instructions in this manual.
Steel surface:
※ It is necessary to thoroughly remove oil and rust, etc., to achieve the rust removal standard Sa2.5, and the roughness reaches 30um-75um; Adopt manual rust removal method, need to reach the rust removal standard St3 level.
Concrete surface:
※ Concrete surface should be flat, dry, no seepage floating and water. The base that has been polluted by grease and chemicals can be washed with detergent, lye or solvent, and can also be treated by fire baking, steam blowing, etc., but it must not damage the base.
