Surfaces must be stable, dry, free of grease and dust and must not contain adhesive repellent coatings. Porous surfaces may need to be primed using a suitable primer. BOSIG butyl strip EPDM is recommended for application to windows and doors.
The BOSIG EPDM membrane can be bonded to a substrate using a suitable adhesive sealant or contact adhesive – BOSIG Fasatan Sausage 600ml. If the BOSIG EPDM is to be used as an airtight vapour barrier membrane, the membrane should overlap by 20mm at the seams and be sealed with a suitable adhesive sealant.
The installer must first apply a sample of the BOSIG EPDM and test the adhesion to see if it’s appropriate.
