Two part Flexible Epoxy primer

This product is a unique, extremely flexible, two-component epoxy membrane. It is solvent-free and exhibits excellent tensile strength and elongation under ambient as well as colder temperatures.

It will give strength back to the substrate and is used as the primer with all the Liquid Rubber EPDMs where required, inlcuding Liquid Roof for motor home and caravan roofs.


ADVANTAGES
• 100% solids for low odor during installation
• Less hazardous.
• Self-priming and leveling on properly prepared surfaces.
• Strong adhesion to wide variety of substrates.
• Self-leveling when sufficient material is applied.
• Fills depressions, spalled areas and cracks.
• Absorbs movement to help prevent reflective cracking.
• Remains flexible over a wide range of temperatures.
• Adheres to asphalt substrates.

Applying ProFlex over smooth non porous surfaces 

Smooth Aluminum, New Galvanized Steel, Glass and Plastics such as ABS, Polypropylene, PVC, Polystyrene, and Acrylic must be primed with Proflex Primer® to improve adhesion. Hypalon and other Thermoplastic Olefin membranes must also be primed with Proflex Primer.

Using ProFlex Primer on spray On Urethane Foams

Since there can be considerable variations in density we recommend priming all roof foams with Proflex Primer in order to produce a uniform surface and improve adhesion to the rubber. 

Applying ProFlex Primer over Previously Painted Surfaces

Epoxy and Urethane patching products, caulks and coatings must be primed with Proflex Primer to improve adhesion.

Applying over porous surfaces

When applying over porous substrates, use Proflex Primer to stabilize the surface.

Applying over Masonry or Concrete 

With masonry / concrete, the surface to be coated must be relatively smooth (steel troweled) and uniform (not honey-combed, full of imbedded stones or aggregate breaking the surface, etc.). The surface must be structurally stable, dry, non-porous, and free of oils, debris, and flaking or loose paint. New (green) concrete should be aged 10 days. Fill any cracks, or spalling or other surface defects on the concrete surface with Proflex Flexible Epoxy, Butt Putty Crack Filler Gel or ProFill to level and smooth out the surface. 

When to use Proflex with Liquid EPDM

Using Proflex Primer with EPDM Liquid Rubber An example of substrates that need to be coated with Proflex Primer prior to application of EPDM Liquid Rubber are:


• Wood
• Plywood
• Concrete

ProFlex Primer Application Guidelines

• Rigid Foams
• Previously Painted Surfaces
• Spray on Urethane Foams


When applying over the above substrates, use Proflex Primer to stabilize the surface. The “porosity” of concrete / masonry can be somewhat subjective and needs to be addressed prior to applying EPDM Liquid Rubber on such surfaces. When in doubt and when time permits, prepare the surface as above and apply a 20 mils dft coat of EPDM Liquid Rubber to a test section. Check when cured in about 4 to 10 days, for surface “bubbling” and adhesion. Bad adhesion and “bubbling” indicates that the structure is too porous. In such a case, or when testing times do not permit, it is recommended you apply a coat of Proflex Primer on the concrete first, to “fill in the pores”, let partially cure, and then apply the EPDM Liquid Rubber over the Proflex Primer following the instructions.
