TUFF-POXY PRIMER #2 is a two-component, solvent borne epoxy primer/sealer. It is a high penetration primer/sealer for use with urethane deck coating and waterproofing membrane systems where solvent based primers can be tolerated.

Basic uses: TUFF-POXY PRIMER #2 is also used as a primer/sealer for porous substrates such as wood, plywood, concrete and for surface treated (pre-primed) metal. It is insensitive to humid application conditions and will cure well in the desert as well as tropical environments. Tests have shown that the use of TUFF-POXY PRIMER #2 as a barrier coat significantly reduces the incidence of pinholing and surface imperfections in polyurethane waterproofing installations as compared to similar applications on an untreated substrate. TUFF-POXY PRIMER #2 enhances the long-term adhesion of the polyurethane membrane to the substrate. It is also an excellent coating for dust proofing concrete. TUFF-POXY PRIMER #2 also has good adhesion to properly cleaned ferrous metal.

Color:   Side-A: Clear

Side-B: Amber

Packaging: TUFF-POXY PRIMER #2 is packaged in kit form. The VOLUME MIXING ratio is 1 part Side-A to 1 part Side-B (Side-A / Side-B = 1:1). TUFF-POXY PRIMER #2 is available in kits of two (2) and ten (10) gallons.

Warning: The A & B-Sides of this product are considered Dangerous Goods. They are classified as: RESIN SOLUTION, Class 3, UN 1866, PG II, FLAMMABLE LIQUID.

Surface preparation: All surfaces to be coated with TUFF-POXY PRIMER #2 must be free of all contamination including visible water, curing compounds, oils, grease, paint, and dirt. Concrete surfaces should be free of roughness which will show through and be noticeable in the completed application. Concrete can be cleaned by shot blasting, hydroblasting or acid etching (followed by neutralizing and thorough rinsing with a pressure-washer) and allowed to completely dry.

Mixing instructions: TUFF-POXY PRIMER #2 Side-A and Side-B should be thoroughly agitated prior to mixing to ensure a homogeneous material. TUFF-POXY PRIMER #2 must always be mixed using equal amounts of Side-A and Side-B. The combined components should be thoroughly mixed using a mechanical mixer at slow speed for a couple of minutes or mixed for at least 5 minutes if mixed by hand.

Optional: (If odor or the use of flammable solvents is not a concern.) Additional small amounts of solvent can be added if desired and if allowed by local VOC regulations. Contact the factory to determine the amount of solvent which can be added in fluid ounces per gallon of mixed A & B. Blend with a mechanical mixer (explosion proof) for 3 minutes. Induction time is not required.

Application: TUFF-POXY PRIMER #2 Side-A and Side-B must be mixed thoroughly and in the proper ratios to assure proper curing. The mixed viscosity is suitable for roller coating, brushing, or spraying with a pressure pot. TUFF-POXY PRIMER #2 should be applied at a rate of 300-350 square feet per gallon depending upon the profile, texture and porosity of the surface being primed. Cure time will vary with temperature and weather and if exposed to direct sunlight. The higher the temperature and greater the exposure to sunlight, the faster the cure. A typical cure of 3-4 hours at warm daytime temperatures in shady areas is recommended or two hours if exposed to hot direct sunlight. The coating must be applied over the cured primer the same day for proper adhesion.

Equipment cleanup: Equipment should be cleaned with an environmentally-safe solvent, as permitted under local regulations, immediately after use. The primer is difficult to clean up after it has cured.
