Suitable Surfaces
 Steel and non ferrous metals properly prepared and blast cleaned to ISO-Sa2½
 Concrete free of contamination, dust and efflorescence, and properly prepared
 Wood must be abraded with sand paper No. 320 and primed with PU or polyester wood
sealer
Application Conditions
Substrate temperature should be 10°C or above for applicaƟon and during cure and a minimum of 3°C above the dew point. Adequate dry air venƟlaƟon is recommended for optimum drying.
Application Information
Thinning should only take place after the two components have been thoroughly mixed.
Brush and Roller Thin if required with 0-5% Paint Thinner Colorama TH908UE or.
Conventional Air Spraying
 Thin with 5-25% Paint Thinner Colorama TH908UE, as required.
