Suitable Surfaces:

• Steel and non-ferrous metals properly blast cleaned to SIS-Sa 21/2 minimum, dry, dust free and wit no soluble salts present.
• 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 aluminum substrates , thorough washing and sweeping with a nonmetallic blast medium is required.

Application Conditions:

Substrate temperature should be 5°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 material has been thoroughly mixed.

Brush and Roller:

Thin if required with 0-10% COLORAMA Thinner 921.

Conventional Air Spraying:

• Thin with 5-15% COLORAMA Thinner 921, as required.
• Tip size – 2.0 mm.
• Tip pressure – 60 psi (0. 4Mpa) approximately.

Airless Spraying:

• Thin with 0-10% COLORAMA Thinner 921, as required.
• Tip size – (0.2-0.3mm) approximately.
• Tip pressure – (120-150) atm. approximately.

Cleaning Thinner:

Equipment should be cleaned immediately after use with COLORAMA Thinner 921.

Drying time:

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