The required quality of surface preparation can vary depending on the area of use, expected durability and if applicable, project specification. It is important that all hot work is completed before coating commences. zinc epoxy Surface preparation and coating should normally be commenced only after all welding, degreasing, removal of sharp edges, weld spatter and treatment of welds is complete. When using standards from other regions it is recommended to reference only one corresponding standard for the substrate being treated. Referred standards Reference is generally made to ISO Standards. The Application Guide (AG) must be read in conjunction with the relevant specification, Technical Data Sheet (TDS) and Safety Data Sheet (SDS) for all the products used as part of the coating system.
