Suitable for atmospherically exposed surfaces but not recommended for exposure to severe chemical environments. May be spray applied to blast cleaned surfaces. Recommended curing temperature above 10°C. Extended drying times will be observed at lower temperatures.

Sherwin Williams Macropoxy M902 is recommended alternative for low temperature application and curing.


Recommended application via brush or airless spray onto blast cleaned surfaces. Recommended cleanser / thinner no5 for thinning, no9 or no13 for cleaning. Recommended undercoat Transgard TG116.

Ensure the surface to be coated are clean, dry and free from all surface contamination.
