GET MORE INFORMATION

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

After you have applied the ProFlex primer you may be able to apply the liquid rubber that very same day depending on temperatures. The ideal time to apply the Liquid EPDM is normally within 24 hours after application that is because it is tacky enough that you are able to walk on your roof without getting any of the primer up on your shoes but you are able to hear you shoes lifting from the primer. If you wait too long, normally after 48 hours the primer will have dried out and you would need to recoat the surface again. We always suggest to our customers that they check the primer about 8 hours after it has been applied to see how quickly it is setting up. The higher temperature the less time you need to wait to apply the Liquid Rubber.

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 250 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.
