Why EPDM?
EPDM (Ethylene Propylene Diene Monomer) refers to the chemical make up of the rubber used in the RPU membrane.
EPDM is excellent for both new construction and roof replacement. It is capable of withstanding temperature variations from -50 degrees F to 240 degrees F without cracking or deteriorating. EPDM offers high tensile strength, extreme elongation capabilities, and is generally compatible with other materials used in most roofing applications.
Our 120� calendering operation is the largest in the industry, allowing us fewer seams in wider material. The major advantage to you is a quality standard no other manufacturer can match for on-site durability. Added to the RPU state-of-the-art seaming operation, you are assured of the very finest single-ply material available anywhere.
RPU has access to the most sophisticated research and development center available today in the independent rubber and plastics business, making RPU the only name you need to remember for your single-ply business.

codes.
Position the EPDM membrane over the substrate, wood decking, concrete, or insulation, without stretching the sheet. Allow sufficient materials for perimeter attachment. When the new membrane is to be sealed to an abutting membrane, overlap the edge of the new membrane 5� onto the "in place" membrane.
Bond the new sheet to the substrate by folding the sheet lengthwise on to itself so that one half of the underside is exposed. Smooth out all the wrinkles and buckles along the folded edge. Apply the bonding adhesive evenly at the rate of 120 sq. ft. per gallon per surface using a 9" plastic core paint core paint roller or approved spray application equipment. Allow the adhesive to dry until it is tacky and string free to the touch. Roll the membrane onto the substrate taking care to avoid wrinkling by using a "wave" air motion at the leading edge to "roll" the sheet into place. Bond the adhered half of the membrane with a 18" to 24" heavy duty push broom using a pushing motion to achieve maximum contact. Pull back the unbonded half of the sheet and repeat this procedure. Do not apply adhesive to the top surface of any abutting membrane that is to be used as the seam joint.

3.9 CLEANING
1. Area of sheet to
be bonded should first be cleaned with white or unleaded gasoline.
CAUTION: USE CLEANING
SOLVENT SPARINGLY. Do not saturate sheet. Noticeable swelling of sheet
indicates that too much cleaning solvent is being used.
2. Always wear gloves and safety glasses when applying RPU Primer/Activator.
3. BEFORE USE, ALWAYS STIR OR SHAKE Primer/Activator. Be sure that there are no visual signs of separation.
4. Use
Primer/Activator sparingly.
CAUTION: EXCESS
PRIMER/ACTIVATOR MAY REDUCE ADHESION. AVOID SATURATION OF SHEET.
Noticeable swelling of sheet indicates that too much Primer/Activator
is being applied.
5. Never leave Primer/Activator containers open for long periods of time. Evaporation of solvent will cause the primer to thicken which may cause excess swelling of sheet and may reduce adhesion.
6. Apply Primer/Activator with a stiff bristle paint brush. Application on deck sheet should be wet but not saturated with excess solvent. NEVER pour Primer Activator onto sheet and spread. Frequent refreshing of the applicator, while AVOIDING excess saturation of the sheet, is recommended.
7. Prevent contamination of Primer/Activator by frequent changing the paint brush.
8. Dry time is determined by air temperature and quantity of Primer/Activator used. Primer/Activator will dry in 15 minutes when application recommendations are followed. Cold weather (under 50 degrees F) will require additional dry time with 30 minutes being sufficient under the coldest conditions.
9. Proper
application of Primer/Activator will result in no noticeable swelling
of the sheet and a surface totally dry to the touch after sufficient
dry time.
