The ClassicBond SPB Spray Contact Adhesive is a quick and effective alternative to standard bonding adhesive when securing membrane to upstands and detailing or adhering a large ClassicBond sheet.
SPB adhesive is a spray applied, high-strength adhesive, formulated especially for gun application and bonding ClassicBond & ClassicBond Pro EPDM to a variety of substrates.
Suitable for a range of surfaces e.g. timber, brickwork, metal, PVC & concrete.
Note: It is not possible to re-position the membrane once stuck down using contact adhesive.
Application Up-stands:
- Spray the contact bonding adhesive onto the upstand and the back of the membrane from a distance of 100mm-150mm.
- It is also good practice to secure the membrane to the deck perimeter with a 150mm width strip of contact adhesive.
- Ensure that the contact adhesive is touch dry before rolling the membrane onto the substrate/up-stand.
Application Non-Permeable Deck:
- Spray the adhesive on to both the deck and underside of membrane evenly from an approximate distance of 100-150mm.
- Ensure that the contact adhesive is touch dry before rolling the membrane onto the deck.
Installation Tip - Allow sufficient time for the the contact adhesive to become touch dry dependant on weather conditions. If the membrane is bonded whilst the contact adhesive is still wet you may notice air bubbles appearing under the membrane. These will disappear within a short period of time due to the rubber roofing membrane being partially breathable.
