    Conklin Prime Time Plus™ stands out with top-class fire-resistance. It is best suited for application over spray-in-place polyurethane foam and can also be applied on other materials that need a fire-rated coating. Prime Time™ is more useful for preparing very weathered, rough, and irregular substrates of the mentioned type.

    Following top coats work well on surfaces primed by Prime Time™ and Prime Time Plus™:

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

    Coverage Rate

    Following are the coverage rates for both primers, Prime Time™ and Prime Time Plus™:

    • Approximate coverage rate is 1 gallon over 100-130 square feet (sq. ft.) of roof surface
    • Precise coverage rates depend on the actual roof conditions


    When applying Prime Time™ and Prime Time Plus™:

    • Ensure that the personnel have read and completely understood the safety data sheet
    • If personnel are spraying the primers, make sure they use a NIOSH-approved mist / dust mask
    • Also, ensure the personnel are wearing other, relevant personal protective equipment (PPE) because the primers:
      • Contain chemicals that the State of California recognizes as those that may cause birth defects, cancer, and reproductive disorders
      • Are harmful when swallowed
      • Can cause irritation for skin, eyes, and the respiratory system
    • Mix the primers completely with themselves before use (i.e. mix Prime Time™ with itself in the container before use). Similarly, mix Prime Time Plus™ with itself before use
    • Temperature and Moisture guidelines:
      • Ambient temperature must be (a) above 40°F and below 90°F for Prime Time™; (b) above 40°F and below 100°F for Prime Time Plus™
      • Relative humidity must be below 80%
      • Surface temperature should be (a) at least 5°F above dew point but less than 100°F for Prime Time™; (b) at least 5°F above dew point but less than 120°F for Prime Time Plus™
      • Do not apply in inclement weather
    • The surface / roof where you apply the primers should have:
      • Less than 36 sq. ft. of water in any area with a depth of ¼-inch or more at a time of 48 hours after rains
      • Less than 5% of the total surface area under bird baths (i.e. small, irrelevant water ponds on roofs that evaporate rapidly)
      • Arrangements to quickly drain away water
      • Zero ponding water if the surface is polyurethane foam
    • Clean and agitate the roof surfaces thoroughly before applying the primers
    • For touch-up jobs and for application on small-area surfaces, use a natural fiber brush of good quality
    • For application on large-area surfaces, use spray equipment or rollers
    • Allow the primers to dry before applying the top coat
    • Dispose the primers in a manner that adheres to relevant local, state, and federal regulations

    Storage Requirements

    • Store the primers at a cool location that is:
      • Above 40°F
      • Protected from freezing
      • Out of reach of children
    • Close containers tightly when not using the primers
