Contact Adhesive for Roofing

High performance contact adhesive is important when installing EPDM to ensure the integrity of the project. We stock a range of contact adhesives and offer expert advice to help you find the right products for your projects.

PermaRoof and branded bonding or contact adhesives are available with improved coverage rates in a range of sizes and with spray and liquid options to suit your needs.

To calculate the quantity of adhesive needed, you will need the same measurements you used to order the membrane (length and width in metres). Multiplying these two figures will give the square meterage:

E.G. 4 metres (length) x 3 metres (width) = 12 square metres (m2)

If you were looking for a contact adhesive, from the guide below, you can see that you’d need the 5 litre PermaRoof option.

Use the following coverage rates as a guide:

Elevate Bonding adhesives

Traditionally troublesome flat roofing has come a long way in the last two decades, today providing the capability of a long term approach. EPDM membranes now carry a service life expectancy of over 50 years and as such, require careful installation and the use of adhesive and accessories that can keep up.

This is why we developed and selected only high performance adhesives to work alongside RubberCover EPDM in our online store. Find all product, technical and safety information in the downloads section below.

Making the decision whether to use contact adhesive or a water-based option depends on the project substrate – and the weather. If you’re unsure which to choose, here are a few top tips:

Water-based deck adhesive is the ideal choice for timber decks. It bonds best in mild temperatures and may dry too quickly in warmer weather (above 23°C). If that happens, the adhesive may not bond evenly, leading to air pockets. Deck adhesive isn’t too keen on the cold either and may not behave well in temps under 5°C. In these scenarios, it would be better to wait for a mild, dry day or switch to contact adhesive instead.

Contact adhesive (also known as bonding adhesive) can be rollered on (liquid form) or applied using a spray gun and pressurised cannister. It is the one to choose when working on surfaces like concrete, where you would use it in conjunction with a primer. It it more well-behaved than water-based in the heat, as long as you allow it to fully tack off on both the substrate and the membrane.

We offer genuine EPDM membranes at the same price as the people that are selling ‘similar’ membranes, that’s right. With PermaRoof price promise, we are guaranteed to be the best priced, for the same product, with a CE certificate, membrane warranty, and the peace of mind that the products are genuine.
