If looking for a cold bitumen adhesive type system for an external outbuilding/ garage there are three options to consider:
– IKO Trade Underlay with IKO Trade Top Sheet – Up to 10 years life expectancy
– IKO Challenger 180 Sand Underlay and IKO Challenger 180 Green APP Cap Sheet – 10 years material guarantee
– IKO Challenger 180 Sand Underlay and IKO Challenger 250 Green SBS Cap Sheet – 15 years material guarantee
Each system product above can be bonded using IKOpro HP Roofing Felt Adhesive.
As a membrane adhesive, the coverage for IKOpro HP Roofing Felt Adhesive is 1-1.5m2 per litre (1- 0.67L/m2) dependant on porosity of substrate…
So, for an 8x3m roof… enough adhesive would be needed to cover 48m2 (24m2 underlay + 24m2 cap sheet)…
This would equate to 32-48L of adhesive.
