How Do I Paint Over Powder Coated Surfaces?
Powder coating is a type of coating that is applied as a free-flowing, dry powder. Unlike conventional liquid paint which is delivered via an evaporating solvent, powder coating is typically applied electrostatically and then cured under heat or with ultraviolet light. These surfaces are tough to cover over as conventional paints won’t adhere to the surface
Surface Preparation
Clean down the surface and ensure it is dry and free from anything that could interfere or affect adhesion of the primer and materials to be applied. Remove loose and failing material from the surface through scraping or brushing, using a stiff-bristled brush, to a sound edge before feathering with a fine-grade abrasive paper.
Remove all visible signs of organic growth and use Tikkurila's mould removal solution, to treat the affected areas and allow to dry.
If any sound paint remains, clean the area down with Tikkurila's cleaning solution to remove any remaining contaminants and rinse with clean water thoroughly before allowing the surface to dry.
Priming
Prime all over with one full coat of Temaprime EE
Tikkurila's range of two pack polyurethane coatings, Temadur 10 and Temadur 20 are also suitable for priming but are recommended for professional use only
Decoration
If topcoating over Temaprime EE, there are a wide range of interior and exterior products that can be used
If the Temadur range has been used for priming, it should also be used for topcoat.
- Temadur 10, Temadur 20, Temadur 50 or Temadur 90, our range of 2 pack polyurethanes
