450 VOC ALKYD ENAMEL PRIMERS

Form: GDH-1090 Rev.: 032416

.DESCRIPTION AND USES .

Damp Proof Red Primer is a special modified alkyd primer designed specifically to protect rusted steel against further rust and corrosion. Use on rusted steel surfaces where only minimal surface preparation (scraping and wire brushing) is practical.

Heavy Duty Rust-Inhibitive Primers are special high solids alkyd primers with rust-inhibitive pigmentation for heavy-duty corrosion protection of steel surfaces subjected to extreme rust-producing environments, such as coastal areas or heavy industrial atmospheres. Use on clean, heavily rusted, lightly rusted, abrasive blasted or previously painted surfaces.

Zinc Chromate Primers are general purpose, rust-inhibitive, modified alkyd primers designed for lightly rusted, bare, abrasive blasted or previously painted surfaces. These primers may be used as intermediate coats for maximum corrosion protection. These primers are not for use on galvanized steel.

PRODUCT APPLICATION .

SURFACE PREPARATION

ALL SURFACES: Remove all dirt, grease, oil, salt and chemical contaminants by washing the surface with Pure Strength

Cleaner/Degreaser, item #3599402, commercial detergent or other suitable cleaner. Rinse thoroughly with fresh water and allow to fully dry. All surfaces must be dry at time of application.

STEEL: Hand tool clean (SSPC-SP-2) or power tool clean (SSPC-SP-3) to remove all loose rust, mill scale, and deteriorated previous coatings. Abrasive blasting to a minimum Commercial Grade (SSPC-SP-6, NACE 3) with a 1-2 mils (25-50µ) surface profile is recommended for optimal performance. Abrasive blast cleaned steel requires two coats of primer. 769 Primer is intended for sound rusted steel only. Do not use 769 Primer on clean or abrasive clean steel.

PREVIOUSLY COATED: Previously coated surfaces must be sound and in good condition. Smooth, hard, or glossy finishes should be scarified by sanding to create a surface profile. The Rust-Oleum Industrial Enamel Primers are compatible with most coatings, but a test patch is suggested.

APPLICATION

Apply only when the air and surface temperatures are between 32-100°F (0-38°C) and the surface temperature is at least 5°F (3°C) above the dew point. Abrasive blast clean steel requires two coats of primer.
