ClassicBond® Contact Adhesive
This adhesive is specifically designed and manufactured for flat roofing installations. It is for adhering to horizontal and vertical surfaces and is suitable to be used on timber, brickwork, metal, PVC and concrete. A sheepskin roller or a brush is used to apply to the surface and backing of the membrane.

Size: 5.0 Litres (Coverage 7 to 10 sqm)
Size: 10 Litres (Coverage 15 to 20 sqm)
Application Up-stands: Use a 4″ mini roller to apply contact adhesive to both the up-stand and rubber roofing membrane. It is also good practice to secure the membrane to the deck perimeter with a 150mm width strip of contact adhesive. This will stop the membrane from lifting due to shrinkage. Ensure that the contact adhesive is touch dry (tacky) before rolling the membrane onto the substrate/up-stand.
Application Non-Permeable Deck: Using a sheepskin roller apply contact adhesive to both the deck and underside of membrane evenly. Ensure that the contact adhesive is touch dry before rolling the membrane onto the deck.
Note: It is not possible to re-position the membrane once stuck down using contact adhesive.
Installation Tip: Dependant of weather conditions, the contact adhesive will be touch dry in approximately 5-20 minutes. 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.
