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

Bare Steel:

Cleanliness: Blast – cleaning to Sa2 1/2 (ISO-8501-1:2007). Power tool cleaning to min. St2 (ISO 8501-1:2007) may be acceptable, subject to exposure conditions.

Shopprimed Steel:

Clean, dry and undamaged approved shopprimer

Coated Surfaces:

Clean, dry and undamaged compatible primer .

Other Surfaces:

For aluminium substrates , thorough washing and sweeping with a nonmetallic blast medium is required.

Application Conditions

Substrate temperature should be 10°C or above for application and during cure and a minimum of  3°C above the dew point. Adequate dry air ventilation 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 TH921.

Conventional Air Spraying

-Thin with 5-25% Paint Thinner Colorama TH921, as required.
-Tip size – 2.0 mm
-Tip pressure – 60 psi (0.4Mpa) approximately

Airless Spraying

-Thin with 0-20% Paint Thinner Colorama TH921, as required
-Tip size – 0.58-.79 mm approximately
-Tip pressure – 2100 psi (15Mpa) approximately

Cleaning Thinner

Equipment should be cleaned immediately after use with Paint Thinner Colorama TH921.

Drying time:

Drying times are affected by air ventilation, temperature, film thickness and number of coats.
