TUFF-POXY 607-WB is one of the primer/sealers used in the various TUFFLEX moisture-curing polyurethane pedestrian and vehicular deck coating systems. TUFF-POXY 607-WB is also used as a primer/sealer for various substrates including surface treated metal, wood, plywood, and concrete. It is insensitive to humid application conditions and will cure and adhere well on damp concrete and damp wood which has surface dried. Tests have shown that the use of TUFF-POXY 607-WB as a barrier coat significantly reduces the incidence of pinholing and surface imperfections in polyurethane waterproofing membrane installations as compared to similar applications on an untreated substrate. TUFF-POXY 607-WB enhances the long term adhesion of the waterproofing membrane to the substrate.
- Limitations
Surfaces to be coated should be surface dry, clean, and free of foreign material. The TUFF-POXY 607-WB coating must be allowed to cure for a minimum of 3 to 4 hours at 75oF if substrate coated is in the shade or indoors and 1 to 2 hours if exposed to direct sunlight. The base coat must be applied over the TUFF-POXY 607-WB within 24 hours; 16 hours if substrate temperature is 85oF or above. TUFF-POXY 607-WB cures faster when applied under warm temperatures and low humidity conditions and slower when applied during cool weather and high humidity conditions.
- Installation
Surface Preparation: All surfaces to be coated with TUFF-POXY 607- WB must be free of all contamination including curing compounds, oil, grease, paint, and dirt. All joints should be caulked with a polyurethane elastomeric sealant. Concrete surfaces should be free of roughness which will show through and be noticeable in the completed application. Concrete should be cleaned by shotblasting, hydro-blasting or acid etching (followed by neutralizing and thorough rinsing with a pressure washer) and allowed to dry for at least 24 hours.
Application: TUFF-POXY 607-WB Part A and Part 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. TUFF-POXY 607-WB is white in color when first applied, but dries to a clear finish. TUFF-POXY 607-WB should be applied at a rate of 250 to 350 square feet per gallon. Cure time will vary with temperature and humidity and if exposed to direct sunlight; the higher the temperature and greater exposure to sunlight the faster the cure. A minimum cure of 3 to 4 hours at 75oF in shady areas is recommended or two hours if exposed to direct sunlight at temperatures below 75ºF. Under normal conditions the top coat should be applied over the cured TUFF-POXY 607-WB primer within 16 hours for proper adhesion.
