Installation Instructions

These step-by-step Firestone Rubber Cover installation instructions will assist professional installers to cover a roof with a Firestone RubberCover™ EPDM System in accordance with the high standards specified by Firestone Building Products.

Adhering the membrane

Firestone RubberCover™ EPDM membranes must always be fully adhered to the substrate by applying RubberCover™ Bonding Adhesive both to the membrane and the substrate. Compatible substrates are wood, bitumen, PIR and PUR insulation, concrete, aluminum and zinc. Firestone RubberCover™ EPDM membranes can be installed on both new and existing roofs.
Firestone RubberCover™ EPDM can overlay virtually any old roof provided the roof decking is sound and the existing structure can carry the load of the new roofing system.

  • Step 1:
    1. Position the membrane on the substrate.
    2. Let it relax for 30 minutes.
    3. Fold back half of the membrane.
  • Step 2:
    1. Apply RubberCover™ Bonding Adhesive to the underside of the folded membrane.
    2. Apply RubberCover™ Bonding Adhesive to the substrate to be covered.
  • Step 3:
    1. Let both surfaces dry until adhesive no longer sticks to the finger when touched.
  • Step 4:
    1. Roll the membrane onto the substrate.
    2. Sweep with a soft brush.
    3. Repeat these steps for the other half of the membrane.

On site seaming

Firestone RubberCover™ EPDM membranes are available in large, seamless sheets so that most small
residential roofs can be covered with one single sheet. If there is a need to splice two adjoining EPDM membranes
on site, this can be performed with the use of RubberCover™, QuickPrime Plus and RubberCover™ QuickSeam Batten Cover Strip.
Do not leave space between adjacent EPDM membranes (a slight overlap is allowed).

  • Step 1:
    1. Apply RubberCover™ QuickPrime Plus to both sides of the joint to a total width of 20 cm.
    2. Wait until the primer is dry to the touch.
  • Step 2:
    1. Remove a piece of the release paper from the RubberCover™ QuickSeam Cover Strip.
    2. Position it over the seam area treated with RubberCover™ QuickPrime Plus.
    3. Pull the release paper at a 45° angle from under the RubberCover™ QuickSeam Cover Strip.
    4. Adhere the strip to the membrane with a flat hand. Make sure no air bubbles are trapped inside.
  • Step 3:
    1. Roll the strip with a hand roller, rolling at right angles over the seam.
