PROFLEX PRIMER®
BB-1501 White

SUMMARY DATA SHEET

Once the ProFlex is applied, the Liquid EPDM must be applied within 24-48 hours to ensure proper adhesion. The ProFlex needs to be a little tacky when applying the Liquid EPDM. If the ProFlex is tacky but does not pull up when you walk on it that is the ideal condition to apply the Liquid EPDM. If the ProFlex is allowed to dry the Liquid EPDM will not adhere properly. This will necessitate you waiting until the ProFlex has fully dried and then sand and recoat before re-applying the Liquid Rubber. The day which you apply the ProFlex primer needs to be above 50 degrees. Lower temperatures at night will slow the cure but will not affect the product. Do not apply ProFlex if you anticipate freezing temperatures BEFORE you are able to apply the Liquid EPDM Rubber. NOTE: The above procedure is not recommended for use in climate zones that experience temperatures below zero degrees F.

NOTE:

For our customers who are applying the primer over asphalt, please you should not have any visible separation of the layers. For any cracked areas around ridges they must be first cut out and filled in with the (ProFlex) primer and reinforced with our polyester fabric. For the Asphalt substrates there cannot be any separation between layers. Cracked ridges must be cut out and filled with PROFLEX and rubber mix and then reinforced with POLY FABRIC.
If you are using the Proflex Primer for an ASPHALT or TAR application it cannot be used areas of the country that are susceptible for prolonged “zero” degree temperatures. This does not mean wind-chill temps but actual ambient air temperatures.

Applications

application_for_uses

After the primer is applied and depending on your temperatures in your state it may be possible to apply the liquid EPDM the same day; however, most of our customers will wait until the next day. What is important to remember about the primer is that you cannot let it dry. The primer actually still needs to be tacky when applying the top coat. A general rule of thumb is if you can walk over the primer and when you lift you shoes you hear your shoe lifting but you are not picking any of the material up on your shoes you are now ready to apply the Liquid EPDM. Now we are not suggesting walking around your roof and ruining your shoes. Simply pressing your hands into the primer slowly and lifting up will give you a good barometer to see how close you are. We suggest checking about eight hours after it has been applied to see how quickly it is setting up.

Its Usage

  • Existing Epoxies and even Urethanes coatings cannot be readily recoated without encountering intercoat adhesion problems. Proflex Primer® makes it possible to recoat them with the same or different type of coating.
  • Badly deteriorated wood and foams which have degraded surfaces
  • Proflex Primer® when applied to EPDM rubber membrane will prevent swelling caused by absorption of oils, fats and solvents around restaurant roof vents.
  • Thermoplastic membranes for example Hypalon

Properties and Appearance

Proflex is not meant to be used as the final coat as it will start to chalk normally after 2-3 months of continual exposure to the sun.

The film after the product cures is very flexible but also has significant tensile strength. It is for this reason that permits the product to reconstitute and ultimately stabilizes severely weathered and deteriorated surfaces.

Many people have asked us about the water and chemical resistance. The product has been tested and does in fact perform very well in these environments but it really is designed as a middle or “intermediate” coat to bond to existing surfaces or substrates which the Liquid EPDM cannot by itself.

Preparing the Surface

Substrate must be dry, and clean of any loose debris such as algea, dirt or living moss or oils. You want to be sure nothing is picked up in the nap of the roller during the application. Any loose chips or peeling must be removed. You should also either replace or make any necessary repairs to fasteners before applying the primer. If you have access to it many of our customers have used a power wash and let it dry.

Applying the Product

For flat surfaces the easiest method is a squeegee and a medium nap roller (1/4 inch short nap). In certain circumstances a pot sprayer can be used if the pot life limitations are not an issue for the installer.

Recommended Spreading Rate

The spread rate is 150 sq. ft. per gallon or (200 sq ft per gallon set). This will result in a 9-10 mil dry film assuming a flat surface. Rough or porous surfaces will require a lower coverage per gallon.

Product Data

  • Percent of volume solids is volume 86% by weight 89%
  • Gallon weight nine pounds
  • Spread rate at 1 mil 1379 square feet (this is NOT the required coverage but theoretical coverage)
  • Ratio equal parts of A and B
  • Viscosity at @ 77° F is 71-KU
  • Time to use product once mixed is 45 minutes at 70° F
  • Cure Time 10 hours to touch at 70° F
  • Strength is 250 psi

      The epdm rubber roof was easy to work with. I am very pleased after having a leaky roof that will be good for many years to come. Roof had mold on it so we first killed the mold with Clorox and water and scrubbed I down and then cleaned the roof with Dawn dish detergent. Attached are the before and after pictures. ThanksRick M.

    • Staff at EPDM Coatings,

      My 29, RV had a couple leaks, at the front where the aluminum and rubber roof came together under a molding, and under the radio antenna. I purchased the 5 gallon bucket. I mixed as directed, then poured mixed product into another clean bucket, scraped it clean, and mixed a few more minutes. After preparation, I applied the liquid rubber around all edges and roof fixtures, I poured small amounts out of the bucket onto the roof and distributed with squeegee or roller as needed, until product was gone and… Read more

    • Hello,

      My name is Jeremy Berkheimer and I purchased the liquid roof coating earlier this spring. I am attaching the before and after photos of my 38 sandpiper roof. This coating was awesome. It took some real cleaning before hand and a I got a bit of extra exercise spreading it but the finished product seems well worth it. Thanks!

    • Hi

      Please find attached before and after photos for my camper roof. I forgot to snap a pic of the before, so I had already started applying the Proflex primer when I took the picture. You can still see the condition of the roof though! Also, the after pic was after the newly coated roof endured it’s first rainfall.

      Hi Everyone, I completed my project and it was much easier than I thought, I wish I had done this years ago, and glad I chose this coating versus the other offerings out there. I will send you 2 more emails, this is the start of cleaning, next is primer, the third is the coating. Hope they are worth of a gift card. Thanks
