The ClassicBond fully-adhered system will adhere to wood, wood fibreboard and lightweight concrete. This product may NOT be applied to polystyrene insulation. The ClassicBond Water Based Acrylic Adhesive is intended for bonding to timber surfaces only. Other surfaces must be bonded with ClassicBond Contact Bonding Adhesive. Roofs over 100m² must also be installed with Contact Bonding Adhesive.

Be sure the roof surface is clean, free of dust, dirt, rust, oil, grease, and loose material. The roof surface must be dry.

This product will not adhere to wet or damp surfaces. Trapped moisture may vaporize and negatively affect the performance of this product.

Good roofing practice dictates that ponding water be prevented. The roof surface should have a positive slope of at least 1 in 80 to prevent ponding water conditions. Before starting please consult the “Precautions” section at the beginning of this manual.

If the Contact Bonding Adhesive is not allowed to properly dry, gas bubbles or blisters may form under the membrane sheet. These bubbles or blisters may subside over time.

Due to solvent flash off, condensation may form on freshly applied adhesive when the ambient temperature is near the dew point. If condensation develops, possible surface contamination may occur and the application of adhesive must be discontinued. Allow the surface to dry and when conditions allow apply a thin refresher coat at a coverage rate that is approximately half of the normal coverage rate when re-adhering a previously coated surface.

Extreme care must be exercised when working on ladders, roofs, or at elevations above ground. If used as an emergency repair to a roofing system, contact the roofing system manufacturer for compatibility and to ensure compliance with terms and limitations of the warranty.

Surface can be slippery when wet, damp, or frost covered.

Do not stretch the product during installation.

Do not expose product to temperatures in excess of 82° C (180°F).

This product is not intended for use where roof top traffic or activity is anticipated without a protective layer installed on its surface.



ClassicBond Contact Bonding Adhesive is used on all vertical surfaces on the roof area, e.g. wall upstands, batten and sky light edges. This adhesive will work on porous and non-porous surfaces, providing they are clean and dry. The Bonding glue will enable tight angles to be formed quickly and easily to give great product versatility.


Step 1


Apply the Contact Bonding Adhesive to the side of the RUSS strip or exposed decking. Also apply the contact bonding adhesive to the relevant upstand termination or step down and to the back side of the ClassicBond EPDM rubber roofing membrane.

Step 2


Once the adhesive has become touch dry with no wet puddles, mate the two surfaces together. Leaving no voids between the ClassicBond membrane and the receiving surface

Step 3


Applying positive pressure to the membrane work the membrane up the upstand to the desired height. These areas should be rolled to achieve a strong bond between membrane and substrate.
