Conklin Tack Coat™ Primer

Product Description

Conklin Tack Coat™ is a primer for application over approved roofing membranes. When used in combination with Wac II™, Conklin’s high-strength and weathered acrylic roof cleaner, Tack Coat™ prepares aged and hard-to-adhere roof substrates for the application of base coats and top coats.

Also acting as a promoter of adhesion or bonding, Tack Coat™ prepares the following types of roofing substrates:

• Hypalon
• EPDM
• TPO
• PVC

After priming these roof surfaces, you can apply the following of Conklin’s base coats and top coats:

• Rapid Roof™ III Acrylic Latex Roof Coating
• Equinox™ Acrylic Latex Roof Coating
• Benchmark™ Acrylic Roof Coating
• PUMA XL™ Polyurethane-Modified Acrylic Roof Coating

Coverage Rate

• Approximate coverage rate is 1 gallon per 250-300 square feet (sq. ft.)
• Exact coverage rate depends on the roof condition

Application

• Ensure that the personnel have read and completely understood the safety data sheet
• Also, ensure the personnel are wearing other, relevant personal protective equipment (PPE) because the primer:
  • Includes chemicals that the State of California recognizes as possible causatives for birth defects, cancer, and reproductive disorders
  • Is combustible
  • Can cause extreme irritation for the respiratory system if you inhale its vapor
  • May severely irritate skin and eyes
  • Is harmful when swallowed
• Other safety considerations during application:
  • Prevent prolonged or repeated contact with skin
  • Use only in well-ventilated locations
  • Protect from sparks, heat, and open flame
• Temperature and Moisture guidelines:
  • Ambient temperature must be above 40^°F and below 100^°F
  • Relative humidity must be below 80%
  • Surface temperature should be at least 5^°F above dew point but less than 120^°F
  • Do not apply in inclement weather
• You can apply Tack Coat™ only after completely cleaning the roofing substrate with Wac II™ as recommended by the manufacturer
• Before application, mix Tack Coat™ completely with itself in the container (you can use a drill-mounted jiffy mixer for mixing the primer available in 55-gallon drums)
• Apply Tack Coat™ at full strength – do not dilute or thin the primer
• Use a brush, conventional airless sprayer, roller, or portable tank sprayer for application
• Tack Coat™ is clear when applied and when it has dried thoroughly
• Allow it to dry completely after application (drying time is between 2 and 8 hours with the exact time depending on temperature and humidity)
• Excessive application or exposure to moisture before it has cured will turn the primer milky white and require extra time for drying
• Dispose the primer in compliance with relevant local, state, and federal regulations

Storage Requirements

• Store the primers at a cool location that is:
  • Above 40^°F
  • Shielded from open flame, sparks, and heat
  • Well ventilated
  • Protected from freezing
  • Out of reach of children
• Close containers tightly when not using the primer
