FAQs

Dusts & Salts
These can physically get in between the powder and the object that is being coated causing the coating to not bond. Care must be taken to ensure that the object to be coated is properly cleaned.


Oils/Grease/Silicon
Powder Coatings will not stick to oily, greasy or waxy surfaces. Feeling the surface to detect oils is not good enough as oils cannot always be detect in this way. High pressure water cleaning and grit blasting do not guarantee to remove oils use of a degreasing chemical is usually the best solution.


Dampness
Moisture can be a problem in both the form of water droplets and high humidity. Moisture can be both static and migrating. Care must be taken to ensure that the correct powder is used for this situation as many powders will fail to stick to damp surfaces and where moisture migrates water filled blisters can often be generated.
