China EPDM Rubber Impermeable Underlayment Roofing Membrane

Self adhesive EPDM waterproof membrane is made from ethylene propylene diene monomer (EPDM), adding into some chemical auxiliaries, for example, carbon black, nanophase modifier, plasticizer, vulcanization accelerator and others, the surface covered with polyethylene film, aluminum foil or fine sand, the base covered with a self-adhesive paper protection kind of self-adhesive flexible waterproof membrane. The product has a good self-adhesive and bending property, it easy to pave. it is one of the most excellent high elastic waterproof membrane with excellent performance elasticity.

Thickness(mm):2mm(1.2+0.8), 3mm(1.5+1.5), 3.5mm(1.5+2.0)Allowable deviation(%):-10to+15Width(mm): 1000,1200Type: Vulcanized & weldable

Advantage:
1).Self adhesive without bonding agent and torching.

Construction Method:
1). Ensure all surface are clean,dry and dust-free. Remove any loose particles and any rust with a wire brush & soft broom.
2).Roll out the membrane.
3).Remove the backing paper and place the adhesive side to the previously prepared surface.
4).To ensure a tight contact-smooth the tape down with a dry cloth, remocing all the air bubbles;
5).Press the tape to the surface firmly once in position.
6).Smooth flat all edages with a wallpaper roller or trowel.
7).After use reseal pack and store upright in cool,dry condition.

Storage and Transportation:
