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:  1) Waterproof materials should be stored under dry and ventilated conditions.  2) Different types of membranes must be piled separately.  3) Under usual condition, storage period is one year since production date.  4) Waterproof materials should be put vertically during transportation.  5)  It should be kept away from sunshine and rainwater.  6) Transport and storage process should be away from the fire source, storage temperature does not exceed 35 ºC, the storage period is 1 year.
