All surfaces to be coated should be clean, absolutely dry and oil or moisture free before painting application. Oil and grease should be removed by solvent cleaning.
ABS Components : Can be applied directly after proper solvent cleaning (preferably by Isopropyl Alcohal) or sanding of ABS surface by emery paper 320/ 400 for proper adhesion. Existing system should be dry and free from loose paint, salt, grease and other contaminants prior to overcoating.
New steel : Abrasive blasting to Sa 2½ (ISO 8501-1:2007). For sheet metal, phosphating cleaning through 3 or 7 tank process are ideal surface prepration techniques. All damage of earlier coating or contamination from storage and fabrication should be thoroughly cleaned prior to final painting.
Maintenance : Remove oil and grease etc. thoroughly with suitable detergent. Remove salts and other contaminants by high pressure fresh water cleaning. Clean damaged areas thoroughly by power tool cleaning to St 3 (ISO 8501-1:2007) (minor areas) or by abrasive blasting to min. Sa 2, preferably to Sa 2½ (ISO 8501-1:2007). Improved surface preparation will improve the performance of the product.
Wood : To be sanded by power grinding or emery paper to a uniform, sharp, smooth profile corresponding to Rz minimum 50 micron. Any dirt, grease, oil, etc. to be removed before application is commenced.
