Nakładanie membran dachowych na rózne podłoża dachowe – w tym wypadku na „rigid roof insulation boards”. Jak się to nazywa „w handlu”.

Adhesion to rigid roof insulation boards varies. Porous and dusty surfaces such as Perlite Board, wood fiberboard and some of the glass scrims, provide poor initial adhesion. The use of a primer, such as Perm-A Barrier® WB Primer will help adhesion to these surfaces. If the primer is necessary, it should be applied at the rate of 6-8 m2/L (250-350 ft2/gal).
