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 4.5m2 per litre
Bonding adhesives
Wet applied
- 5L tub – approx. 7.5m2
- 5L tub – approx. 15m2
- 10L tub – approx. 30m2
Spray adhesives
- We stock Elevate spray adhesives, which have a coverage rate of up to 3m2 per litre.
Alternatively, you can let PermaRoof do the calculations for you. We can custom-build a complete EPDM roof kit to suit your needs – give us a call and we’ll talk through the project with you or you can buy a kit online. Simply enter the project measurements in our online store and we’ll do the rest. Roof kits include sufficient membrane, water based adhesive (for timber decks), sealant and trim where applicable.
