The latest formula Elevate contact spray adhesives have an improved coverage rate of up to 3m2 per litre. The aerosol spray is 0.75l and the large spray cannister could cover up to 75m2.

It is always best to allow concrete to dry out properly before applying adhesive or roofing materials. This is typically around three weeks but can be longer, depending on weather conditions and local temperatures.

It is important to use only contact/bonding adhesive when adhering EPDM or any other membrane to a concrete roof deck. Water based adhesives are used on timber decks only and will not adhere membrane properly to concrete and other types of roof deck. This is because the surface of the concrete is porous. Often, primer is also used in conjunction with bonding adhesive to further prepare

Yes, contact adhesive is also widely known as bonding adhesive across the industry. The products in both categories are the same in our online store.

What is the best way to apply water based adhesive? Water based adhesives can be applied quickly and easily with a good quality roller, such as a paint roller. For smaller areas, a pad can also be useful to help apply an even coat. When installing EPDM, the adhesive coverage should be complete and even across the entire surface area to ensure full adhesion of the

To calculate the quantity of adhesive needed, you will need the same measurements you used to order the membrane. Use the following coverage rates as a guide: PermaRoof liquid waterbased adhesives 5 Litre – coverage approx. 10-12m2 onto dry timber 5 Litre – coverage approx. 20-22m2 onto dry timber 10 Litre - coverage approx. 40-44m2 onto dry timber Elevate water based adhesives Coverage rates up to

5 Litre – coverage approx. 10-12m2 onto dry timber 5 Litre – coverage approx. 20-22m2 onto dry timber 10 Litre - coverage approx. 40-44m2 onto dry timber

Waterbased adhesive is used with EPDM onto timber roof decks only. For adhering EPDM to concrete, bonding or contact adhesive will be needed.
