For the interior, do surface preparation by light sweep-blasting with garnet. Use 1 coat epoxy primer at 50 microns and 1 coat polyaspartic finish at 250 microns. A polyaspartic coating provides the same corrosion protection as an amine epoxy coating but has weatherability and UV resistance comparable to aliphatic polyurethtane. A polyurethane finish is not recommended for immersion service. For the exterior, use the same surface preparation and a 2-coat amine epoxy system of 300 microns. DFT minimum.
