FAQ's (Frequently asked questions)

Does this product cover a concrete roof with tar and gravel, or would I need to remove the gravel prior to installation?

We have several systems that require Benchmark base coat and Benchmark top coat, but any gravel would have to be removed prior to the installation of these systems. Please call the Conklin Building Products division for details. 800-888-8838

What are the application rates for Conklin® coatings over sprayed-in-place polyurethane roofing foam?

Conklin® has three coatings suitable for application over sprayed-polyurethane roofing foam: Benchmark®, Rapid Roof III® and PUMA.

PUMA is a revolutionary single coat polyurethane modified acrylic that can be applied in one coat. This material does not require a basecoat and is applied at 1.9 gallons per square (100 square feet) at a minimum dry film thickness (dft) of 13.5 mils. Application rates are dependent on the smoothness of the foam surface. Rougher foam surfaces will require additional coating.

Benchmark base and top coats are each applied at a rate of 1.9 gallons per 100 square feet. Minimum dry mil thickness for base coat is 13.5 mils. Minimum dry mil thickness for top coat is 13.5 mils. The total coating thickness should be no less than 27 dry mils. Application rates are dependent on the smoothness of the foam surface. Rougher foam surfaces will require additional coating.

Rapid Roof III base and top coats are each applied at a rate of 1.9 gallons per 100 square feet. Minimum dry mil thickness for base coat is 12 mils. Minimum dry mil thickness for top coat is 13 mils. The total coating thickness should be no less than 25 dry mils. Application rates are dependent on the smoothness of the foam surface. Rougher foam sur

Is a spore of mold able to get through pores in Benchmark® or Rapid Roof® and grow?

When applied properly, both Benchmark and Rapid Roof form a monlithic film that would not have "holes" to promote the growth of mold. 

The roof coatings are considered breathable to allow moisture vapor transmission to pass through them, but this function is separate from a mold spore growing in/on a coating. The mold could take hold and spread from dirt and other contaminants ON the surface of the coating but would not grow IN the coating. 

Can I apply Conklin® spray foam insulation?

Knowledgeable applicators and special equipment are required for application of spray-in-place foam (SPF). The product consists of two components. The mixing ratio is 1:1. The two components are heated and mixed at the spray gun.

The mixed material emerges as a liquid and froths into a layer of foam. The foam becomes hard within seconds. Benchmark® or Rapid Roof lll® is then applied to protect the foam from the elements. Please call 800.888.8838 and ask for one of the Building & Roofing specialists for further information.

How can I obtain a Benchmark® Roofing Application Guide?

This Specification Guide contains all information on a successful Benchmark roofing application, including steps for preparation, application and application rates.

What are the optimal temperature ranges for application of Conklin® roofing and interior wall foams?

Conklin spray polyurethane foam is formulated to provide optimal yields when applied within their designed temperature ranges.Temperature ranges for application of Conklin spray foam are as follows:

3.0# Roof Foam
Should yield approximately 2400-2800 board feet/per set (board foot equals square foot at one inch thickness) depending on surface texture, temperature, sunlight, humidity level and wind.

  • CD-348S      90°F +
  • CD-348M     60-90°F
  • CD-348W     45-60°F

2.0# Interior Wall Foam
Should yield approximately 4300-4700 board feet/per set depending on surface texture and temperature.

  • CD-158S      90°F+
  • CD-158M     60-90°F
  • CD-158W     50-60°F
  • CD-178F       >75°F
  • CD-178XF    25-75°F

Spray Foam Adhesive
Foam adhesive should yield 10,000 square feet per set on smooth surfaces (concrete, wood, steel, etc.) and 6,000 square feet on rough or irregular surfaces (BUR/Gravel).

  • Adhesive     40-90°F

Does Benchmark® come in a tan color?

Benchmark Top Coat comes in white or gray only.  Once the Benchmark is dry,you have the option to use Rapid Roof III® (available in tan or gray) or Kolor Kote® Exterior paint to achieve the color of choice.

Does Conklin® carry roofing products that are approved by Florida building codes?

Yes, Benchmark® has been approved. The product application, FL3529 submitted by Conklin Company Inc. on the Florida Building Code information system has been approved. The Florida certificate of product approval number is FL3529. Please visit the link below to view credentials.

What is the shelf life of Conklin® roof coatings?

Conklin® roof coatings, which include Benchmark, Rapid Roof® III, Rapid Roof® HV, Equinox, Puma and Puma XL are manufactured with the highest quality raw materials available. While there is not a definite shelf life, when stored in a controlled environment away from temperature extremes, we recommend you use them within two years of purchase.

A quick inspection of the roofing material as follows will help you determine if it is usable:

  • Material must be smooth and creamy. Any yellow-colored residue or settling solids should be thoroughly reblended with a slow speed mixer.
  • If material smells bad or has a cottage cheese type texture, the material is not usable and should be disposed of according to the laws in your area. Many municipalities sponsor paint drop off days at no charge.
  • Test the coating by spreading on a piece of cardboard or similar material, then evaluate.

What is Benchmark®?

Benchmark is a premium acrylic elastomeric roof coating.  The superior elongation (flexibility) and tensile strength (toughness) of Benchmark combine to make it an industry leader among liquid applied coatings. 

It can be used on metal roofs, over spray-applied foam, and with fabric in a ply system. The Benchmark System consists of a light blue base coat and an Energy Star approved 85%  light reflective top coat.

The use of Benchmark in a retrofit application, over tear off and redo, may have tax advantages and may also qualify the owner for a utilities rebate.  Benchmark allows the building owner to use less heat and air conditioning thus contributing to the bottom line.  It has a UL-790 Class A approval and is also approved by Factory Mutual (FM), International Code Conference (ICC), and Miami Dade.

Benchmark is available in 5-gallon buckets, 55-gallon drums and 220-gallon mini-bulk totes.  Should a color other than white be desired, Benchmark can be top coated with Kolor Kote, available in almost one thousand colors.

Can Conklin® roof coatings or spray foam be applied directly over existing silicone coatings?

Conklin acrylic roof coatings and spray polyurethane foam do not adhere well to silicone coatings.For coating applications, the silicone either needs to be removed or overlaid with an approved substrate, such as plywood, OSB or isocyanurate boardstock before applying a Conklin coating system.

For foam applications, the best procedure is to scarify the top layer of foam off the roof, clean the surface and lightly prime. Install 1/2" of new foam to seal, then another lift of 1" thickness. Finally, top off with a Conklin coating system, such as Benchmark ® or Rapid Roof® III®.

What is the difference in the base coat and top coats of Conklin® elastomeric roof coatings?

The base coats provide better adhesion and are less costly. The top coats provide the utmost in UV protection and are slightly more expensive because of the UV protective components manufactured into it. In addition, Conklin top coats are traditionally bright white to maximize energy efficiency while the base coats are darker colors (Benchmark®, Rapid Roof III®-tan and Rapid Roof® HV-dark gray) to help identify the roofing system, to aid the applicator in applying the correct amount of top coat product for the project and to help the building owner and the contractor in determining when the system is in need of a recoat. Conklin offers Rapid Roof lll, Benchmark, and Equinox  in both base coat and top coat
