FLEXI PROOF™ Contact Bonding Adhesive is a high strength solvent contact bonding adhesive that is designed and manufactured to withstand the temperature extremes of many flat roofing installations.

This contact bonding adhesive should be used to secure edges of the EPDM Membrane and any up stands or angle changes. FLEXI PROOF™ Contact Bonding adhesive can be suitable for a wide range of surfaces e.g brickwork, timber, metal, GRP and concrete

For commercial installations over 100 square meters, the entire roof area should be fully bonded with FLEXI PROOF™ Contact Bonding Adhesive 

The FLEXI PROOF™ Contact Bonding Adhesive is great for bonding EPDM membranes to horizontal and vertical roofs. Best applied with a solvent resistant roller; no other specialist tools required.

  • Roofing surfaces should be clean and free from dust, grease and loose materials.

  • The surface of timber and composite boards must be sound and not degraded.

  • Ensure adhesive is stirred before use.

  • Being in storage of temperatures over 30°C for long periods of time can affect quality.


  • Applied using a short pile roller or brush to achieve a thin coating on both surfaces. A larger quantity of adhesive is necessary for open texture and rough surfaces.

  • Before bonding the materials, ensure the solvent content is evaporated. Time may range from approx. 5 to 15 minutes after application assuming average UK weather conditions.

  • Take time to align the Flexi Proof™ to the surface to be mated. Apply pressure using a roller to remove any trapped air.

  • Trim away any excess membrane.
