Polyurethane

b. Surface Preparation: All surfaces shall be thoroughly clean to levels defined by

SSPC-SP WJ-4/NACE WJ-4 Light Cleaning by use of Low-Pressure Water Cleaning (LP WC) and dry prior to overcoating. Thoroughly power wash surfaces using hot water and detergent at sufficient pressure and flow rate to remove all chalk and surface contaminants. This can usually be accomplished using a rotating nozzle with 140F biodegradable detergent/water solution (1-2 oz. detergent per gallon of water) at 1,000-2,000 psi with 3-5 gallons per minute flow rater. If may be necessary to use some means of additional mechanical agitation during power-washing to help facilitate the removal of chalk or non-water-soluble contaminants.

Rinse surfaces with clean water. If mildew is present, allow the surface to dry and wet mildewed surfaces with bleach solution consisting of 3 parts warm water and 1 part household bleach. Allow the bleach solution to remain on the surface until dry then rinse with clean tap water. If present, clear coats must be thoroughly and uniformly abraded to degloss. De-gloss any areas where coating remains gloss by feasible means. Prepare bare metal and rusty areas according to SSPC-SP11 Power Tool Cleaning to Bare Metal and feather edges for smooth transition into tightly adhered coating. Prepare areas of exposed epoxy according to SSPC-SP3 Power Tool Cleaning and feather edges for smooth transition into tightly adhered coating.
