- Mixing
It is important to remember that TUFF-POXY #7-WB has a limited pot life (1 hour). #7-WB Primer Base Resin (Part A) is black in color and #7-WB Curing Agent (Part B) is amber in color.
- Pre-mix Part A and B components briefly
- Add 0.9 gallon of Curing Agent (Part B) to 2.25 gallons of Base Resin (Part A)
- Mix thoroughly with a Jiffy blade for 3 minutes. Mix until the color reaches a uniform black color
- Slowly add 1.85 gallons of potable water to the mixture while under agitation
- Mix for an additional 2 minutes until the contents are fully dispersed. The fully mixed material will appear as a thin to medium thickness black liquid. Do not mix material in an up and down motion to avoid trapping bubbles or creating a foam
- Application
TUFF-POXY #7-WB Primer should be applied by airless spray onto a properly prepared substrate or applied by spreading the material using a flat squeegee followed by strong backrolling. TUFF-POXY #7-WB is a medium viscosity product and it is recommended to let it flow out in front of the squeegee. Strongly backroll the primer in order to allow for sufficient wetting of the surface and to ensure that the recommended coverage gate (300-350 square feet / gal.) is achieved. Immediately follow the spray or squeegee application by backrolling the covered area, utilizing a ¼” nap roller, to eliminate any puddles on the surface. Minimize the overlap from batch to batch applications while achieving complete surface coverage. The primer cures more rapidly when applied in sunny warm conditions.
- Recoat Window
TUFF-POXY #7-WB has a recoat window of 8 to 24 hours. If the maximum recoat window is missed (24 hours), re-sand the surface with 80 grit sand paper, followed by a thorough sweeping and vacuuming of the area. Then lightly re-prime.
- Limitations
- Substrate temperature must be 5°F (3°C) above measured dew point. Conduct quantitative anhydrous calcium chloride testing in accordance with ASTM-F 1869. Maximum acceptance test results is 8 pounds per 1,000 sq. ft. per 24 hours. TUFF-POXY #7-WB Primer is NOT designed for exterior exposure, immersion, or any use where moisture can reach the underside of the resurfacer. Freshly applied TUFF-POXY #7-WB Primer should be protected from dampness, condensation and water for at least 24 hrs.
- Do not add any type of thinner to TUFF-POXY #7-WB Primer. Addition of thinners will slow the cure rate and reduce the ultimate properties of TUFF-POXY #7-WB Primer.
- TUFF-POXY #7-WB Primer will discolor when exposed to sunlight (UV) and under certain artificial lighting conditions. It must always be coated with a UV resistant, light stable top coat.
- Do not use if TUFF-POXY #7-WB Primer is frozen. Minimum/maximum substrate temperature: 60°F / 90°F (15.5°C / 32°C). Minimum/maximum relative humidity: 10% / 85%.
