The IKO Easyseal Self-Adhesive Fully Bonded Underlay consists of a glass-fibre reinforced carrier coated on either side with self-adhesive bitumen SBS elastomeric coating.
The upper surface is protected with a polythene film that facilitates rapid bonding of the subsequent self-adhesive waterproofing layers. A release film protects the self-adhesive coating on the underside of the IKO Easyseal Self-Adhesive Fully Bonded Underlay. The self-adhesive bitumen coating on the underside provides a full bond to primed substrates.
The IKO Easyseal Self-Adhesive Fully Bonded Underlay is used with all associated detailing, abutments, internal gutters, and penetrations as part of a two-layer built-up roofing system application. It may also be considered for use on main flat areas in cold roof build-ups.
Ideal for new build and refurbishment projects, and commercial and domestic projects, this underlay is suitable for roof pitches up to 5° if reliant on adhesion alone. For roof pitches over 5°, the underlay should also be mechanically fastened in accordance with BS8217 table 5.
The underlay must be used in conjunction with an IKO Easyseal Self-Adhesive Capsheet and be installed in accordance with IKO recommendations.
