Mix lightly prior to application of the coating. KARNAK 404 Corrosion Proof may be applied by brush, spray equipment or roller. For applications in higher temperatures (above 90 °F) KARNAK recommends application in multiple thin coats to prevent trapped moisture problems. Commencement of work by the contractor implies his approval of the deck surface. SPRAY APPLICATION Utilize a standard paint spray pump or airless spray pump. Equipment manufacturer should be consulted for more complete information. Spray application should be done with a 50% over-spray pattern.
- Surface Preparations
Surfaces to be coated should be dry, clean, and free of dirt, dust, grease, oil and loose rust or coating. Power wash surfaces with KARNAK 799 Wash-N-Prep Roof Cleaner and water. Wash roof surfaces with a minimum of 2000 psi. taking all necessary precautions to avoid damage to the roof system. Seal fasteners, seams and flashings with KARNAK 550 Patch-N-Go Fleece self-sealing tape or KARNAK 5540 Resat-Mat and 505MS Karna-Flex WB or appropriate sealants or caulking materials.

- Coverage Rate
Apply KARNAK 404 Corrosion Proof over the surface at the rate of 1.5 gallons per 100 sq. ft. Allow to dry 12 hours then apply the selected finish coating. The total dry mil thickness of KARNAK 404 Corrosion Proof and finish coating should be 20 to 24 mils. Coverage will vary depending on the surface to be coated.

Safety & Health
- Caution
Do not apply when rain is imminent. Protect from freezing. Coating must be dried before exposure to water. Store in a heated room and keep container covered when not in use. Do not thin. Keep out of reach of children. Avoid prolonged contact with skin. Dispose of in an environmentally safe manner. Cover air intakes during application and while drying. For exterior use only. Cold-process systems and coatings, either emulsion or solvent-based, should only be installed on decks with positive drainage. Per NRCA (National Roofing Contractors Association), “The criteria for judging proper slope for drainage is that there be no evidence of standing water on a deck 48 hours after it stops raining.”
