Primer Application Instructions
STEEL: Degrease the surface with Thinner 910. Gritblast to SSPC-SP10/NACE2 (Sa 2.5) near white metal surface. If gritblasting is not possible, grind metal surface with 24-36 grit abrasive discs to a uniform, clean, bright metal surface with 2-3 mils to an SSPC-SP-3 / St3 standard. Use an angle grinder on smaller areas. Ensure that the substrate is contaminant and rust free prior to application of coating. Apply the first coat as soon as possible after the surface preparation.
STEEL with a Shop Primer: Degrease the surface with Thinner 910. Clean the surface with contaminant-free rags and ensure rust, dust, oil, grease, and dirt are removed. NOTE: Shop primer should have been applied to a substrate where standard profile requirements have been achieved.
ALUMINUM: For dry areas: degrease the surface with Thinner 910. For wet areas: degrease the surface with Thinner 910 and scrub well using a marron, 3M Scotch-Brite™ pad (7447).
STAINLESS STEEL: Degrease the surface with Thinner 910. Light gritblast to product a profile of 2 mils.
BARE WOOD: Sand with 120 grit paper. Remove oil from oil woods (teak) using Thinner 910. Change cloths frequently.
LAMINATE: Closed and sound condition laminate only. NOTE: Fibers are impregnated with resin, no fibers exposed. Degrease the surface with Thinner 910. Scrub well using a maroon, 3M Scotch-Brite™ (7447) pad.
GELCOAT: Degrease surface with Fiberglass Solvent Wash 202 using the two-cloth method. Sand with 80 grit paper. Ensure sanding debris is removed by wiping down with Fiberglass Solvent Wash 202 before proceeding.
POWDER COATED SURFACES: Degrease the surface with Thinner 910. Scrub well using a maroon, 3M Scotch-Brite™ (7447) pad.
