PROFLEX PRIMER®
F1501 White
1:1
PRODUCT DATA SHEET

Proflex Primer® is a two-component, ready to apply, flexible epoxy primer with a one to one volume mix ratio.

NOTE:
The Asphalt substrates cannot have 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 in areas of the country that are prone to snow. If you are using the Primer in conjunction with the Liquid EPDM, snow is not an issue.

Applications

Built-Up Asphalt Roofs	Asphalt Shingles There cannot be any separation between layers. Cracked ridges must be cut out and filled with Proflex and rubber mix plus reinforced with Poly Fabric	Galvanized Steel
Copper	Concrete and Masonry	Stainless Steel
Wood and Masonite	Rigid and Flexible Foams	Rubber Membranes
Epoxy Coatings	Thermoplastic Membranes	Urethane Coatings
Plastics	Elastomeric Coatings	Fiberglass
Elastomerics	Acrylic and Alkyd Coatings	Polyurethane Foam
BUR	Modified Asphalt Roll Roofing	Modified Asphalt
	Hot Mop

IMPORTANT: LIQUID EPDM MUST BE APPLIED NO LESS THAN 24 AND NO MORE THAN 48 HOURS FOR OPTIMUM ADHESION. ONCE THE EPOXY HAS FULLY CURED, THE RUBBER WILL NOT ADHERE WELL WITHOUT FIRST A VIGOROUS ABRASION.

Usage

• Existing Epoxy and Urethane coatings cannot be readily recoated without encountering inter-coat adhesion problems. Proflex Primer makes it possible to recoat them with the same or different type of coating.
• Severely weathered wood and insulating foams have degraded surfaces that can be "reconstituted" with an application of Proflex Primer that can then be-topcoated.
• Proflex Primer when applied to EPDM rubber membrane, will prevent swelling caused by absorption of oils, fats and solvents around restaurant roof vents.
• Thermoplastic roofing membranes such as Hypalon and others can be recoated after applying  Proflex Primer.

Properties and Appearance

Cured films are quite flexible, yet have high bond and tensile strength. This enables the product to reconstitute and stabilize severely deteriorated surfaces.

Although Proflex Primer has good water, solvent and chemical resistance it is primarily designed to be an intermediate bond coat so that high performance and special purpose coatings can be applied to existing substrates.

Surface Prep

Substrate should be dry, free of debris, dirt, moss, algae, mildew and oil. Loose or peeling paint must be removed. Make repairs and tighten or replace fasteners prior to the application of primer. High pressure washing is an effective cleaning method.

Method of Application

A combination of rubber squeegee, roller and brush are most practical on flat surfaces. A pressure pot spray system may be used if pot life limitations can be adhered to.

Recommended Spreading Rate

When spread at 250 sq. ft. per gallon a 5.5 mil dry film will result on a smooth surface. Although this is sufficient for bonding to the substrate it may be difficult to achieve in practice. A squeegee and roller application will usually result in covering 150-175 sq. ft. per gallon which results in an average dry film thickness of 8-9 mils. Rough or porous surfaces will require a lower coverage per gallon.

The above data is gathered in a controlled Laboratory environment. Your conditions will vary. Pot Life, Gel Time, Dry Time and Cure Time will all be affected by ambient as well as surface temperatures. Higher temperatures shorten the time you have to work with the product. Always mix thoroughly and immediately pour the product onto the surface to be coated. Only mix the amount you can easily spread within 30 minutes.
