Proflex Primer® has two parts and is an easy, one to one mix ratio that makes application simple.
KEEP IN MIND:
You must repair cracked ridges with PROFLEX and a rubber mix before applying Proflex Primer on asphalt.
Applications for Use
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.
Where Can I Use It?
- Exceptionally weathered insultation foam and wood can be vastly reinforced with Proflex Primer® if you apply a top coat afterward.
- Thermoplastic roofs are a great surface for Proflex Primer®.
- EPDM rubber and Proflex Primer® are a great fit, and it can reduce swelling.
- Current epoxy or urethane coatings are optimal matches for Proflex Primer®.
What’s Proflex Primer For?
Proflex Primer is a great water resistant, chemical resistant coating. However, you should only use it as a middle coating. It’s best to apply a top coat, whether it’s Liquid Rubber or Liquid Roof. By itself, it’s flexible and strong, but not designed as a stand-alone coating.
Prepare Your Surface
Make sure there’s no dirt, algae, oil, mildew, flaking paint, or areas that need repair. A good pressure washing can effectively clean surfaces.
Apply Proflex Primer
All you need is a roller, brush, and squeegee for flat surfaces. You may also use a pressure pot spray.
How Fast Should It Spread?
You should aim for 200 square feet per gallon to achieve a 5.5 mil. coating. This can be tough. If you apply the primer by hand (squeegee or roller), you can expect to cover about 160 square feet per gallon. You’ll need more primer if the surface is porous or rough.

This information was obtained using a controlled lab, but your results might vary. Outside temperatures, oxygen, and how quickly you work can all impact the results. Remember the hot temperatures speed up cure time, which can be good—but not if you’re a slower worker. Make sure the contents are completely mixed and never left out. Plan to work in half hour increments. For more information, call us at 855-281-0940.
