Elastomeric Membrane
EPDM FULLY ADHERED SPECIFICATIONS

Why EPDM?

EPDM (Ethylene Propylene Diene Monomer) refers to the chemical make up of the rubber used in the  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  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  state-of-the-art seaming operation, you are assured of the very finest single-ply material available anywhere.

We has access to the most sophisticated research and development center available today in the independent rubber and plastics business, making us the only name you need to remember for your single-ply business.

3.4 INSTALLATION OF EPDM MEMBRANE

The EPDM membrane may be installed in a fully adhered application directly over the exsiting BUR, modified or other acceptable exsiting roof material as long as such is clean, not saturated with water, and is acceptable as a base system by Lottes Roofing. In the alternative you may install 1/2" or larger plywood decking, 1/2" OSB board or 1/2" wood fiberboard directly over the existing roof system, if the deck support is considered adequate for the roof load as determined by Lottes Roofing, and the roof installation meets local building 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.

3.5 LAP JOINTS
A. USE OF SPLICING ADHESIVE
All lap joints: Shall be a minimum of 4' wide. All lap joints shall be shingled where possible toward drains or scuppers. Remove all talc and construction dirt from seaming area with approved cleaners. Allow to dry before application of Splicing Adhesive. Apply splicing Adhesive to both bonding surfaces with 4" paint brush at a rate of 120 lineal feet of 4" lap per gallon. Apply cement in a smooth even coat without globs, puddles, or uncoated areas. Allow Splicing Adhesive to dry until tacky but not stringy.

Join bonding surfaces, taking care to avoid stretching or fishmouths. Roll lap joint thoroughly with a roller in the direction perpendicular to one length of the joint.

Apply Seam Sealer to exposed edge and tool to assure positive contact with both sheets. Apply Seam Sealer to all lap joints completed during each workday. Seam Sealer is not required on tape systems

Lottes Roofing requires that all seams in the deck sheet be covered using 6" wide uncured FLASHING TAPE to qualify for a 15 or 20 year warranty.

B. SELF VULCANIZING LAP JOINTS
All lap joints: shall be sealed using RUBBER TO RUBBER TAPE. All lap joints shall be shingled to shed water toward the drains, scuppers, etc.

Contact surfaces for the RUBBER TO RUBBER TAPE shall be cleaned to remove construction dirt using a light application of unleaded gas on a clean, lint-free rag. After cleaning apply Anjon primer to surfaces before applying seam tape.

The RUBBER TO RUBBER TAPE shall be securely bonded to the bottom deck sheet along the previously mark proper edge alignment of the seam tape on the bottom sheet. The top sheet shall then be lapped onto the lower sheet. The release paper shall be carefully removed without disturbing the placement of either sheet.

The lap joint shall be "walked in" to fix placement and thoroughly rolled with a 2" metal roller in the direction perpendicular to the length of the joint.

3.6 MECHANICAL ATTACHMENT
The membrane shall be secured to the roof deck at the perimeter, large penetrations and the expansion joints.

3.7 FLASHING
A. Flashing: Shall comply with details published by Lottes Roofing. Any deviation from details published by Lottes Roofing is subject to the written approval of Lottes Roofing. Side wall and Unit Curb Flashing shall extend a minimum 4" above the roof deck. Flashing configurations which require field forming shall be flashed using Lottes Roofing approved Flashings.

B. Uncured flashing without tape: Flashing without tape shall be bonded to the roof membrane using Splicing Adhesive. Splice Adhesive shall be applied to both surfaces with a solvent resistant brush or roller. Splice Adhesive shall be allowed to dry until tacky but not stringy.

C. Application of Flashing Tape:

1. Clean entire surface where Lottes Roofing EPDM Flashing Tape will be applied.
2. Apply EPDM primer to entire surface to be mated with the flashing tape. using a stiff bristle paint brush or application pad.  NOTE:  Use caution when installing at temperatures below 40oF (5oC) to prevent blushing of EPDM primer (formation of condensation on surface of primer).
3. Allow the primer to dry to the touch (no material transfer, typically less than 20 minutes).  Dry time will vary depending on ambient temperature and humidity.
4. Once the primer is dry immediately install EPDM Flashing Tape.
5. Position Flashing Tape over primed area and remove release liner.  Press down and form Flashing Tape by hand.
6. Roll the flashing with a 2” (5.08cm) wide silicon or stainless steel roller.
7. Seal edges of flashing detail with  EPDM Edge Sealant IF required.

Work flashing into place, taking care to avoid entrapped air. All flashing shall be hand rolled to assure proper adhesion.

Apply Seam Sealer to exposed edge and tool to assure positive contact with both sheets. Tape flashing is not required to have edge seam sealer. Apply Seam Sealer to all flashings completed during each workday.

D. Uncured flashing without tape: Use the same application procedure as in using uncured flashing without tape, but use the primer in lieu of Splice Adhesive on the deck sheet while using no primer or Splicing Adhesive on the tape product itself. 

 

3.8 TEMPORARY SEAL
All areas of installed membrane shall be sealed at the end of each workday to assure against moisture infiltration beneath completed areas. Methods for temporary seal are at the applicator's option with Lottes Roofing approval.

3.9 CLEANING
Applicators shall remove all debris related to this work from the project site.

3.9 CLEANING

---



COLD WEATHER:


1. When the outside temperature is below 40 °F (4.4 °C), certain combinations of temperature
and humidity may cause condensation on the surface of solvent-based adhesives and
primers. If this condition occurs, discontinue the application. When the ambient air
conditions no longer cause condensation on adhesive surfaces, and the membrane is clean
and dry, then re-apply additional adhesive or primer.


2. The consistency of sealants, adhesives and primers will begin to thicken as the temperature
drops. To minimize this, the following is recommended:
a) Start work with sealants, adhesives and primers that have been stored between 60 F and
80F (15.5 C and 26.7 C). Insulated and heated boxes may be helpful.
b) Complete test areas to determine if conditions will cause problems such as condensation
with the application of the material.
c) Stop the operation or change to another warm container when material becomes too
thick to properly apply.

3. Do not use heat guns or open flames to dry adhesives and primers.


4. No-fold or single fold panels are easier to apply in cold weather and are recommended for
fully adhered systems.


5. When the outside temperature is below 40 F (4.4 C), installation of the Lottes Roofing
EPDM System requires additional application procedures:


 Ensure that the roof surface is dry. Moisture may cause poor adhesion, and may lead to moisture
entrapment within the roofing system.
 Use of temporary roofs should be considered when roof applications must occur in cold or potentially
wet weather to permit continued interior construction or roof-top work to proceed.

 Use of heat guns to warm flashing material should be considered to increase flashing flexibility if
flashing material is difficult to form. By preheating (warming) the tape flashing before installation to the primed

EPDM deck sheet, the possibility of shrinkage or pull back is greatly reduced. When applying tape flashings with ambient temperatures

below the recommended installation temperature minimums the possibility of shrinkage and pull back of the uncured tape flashings can result.

ADHESIVE PRIMER/ACTIVATOR
APPLICATION RECOMMENDATIONS

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.
