If HDPE polymer self-adhesive film waterproofing membrane is used as a wall waterproofing material, weak adhesion or large gaps may be encountered when pasting the waterproofing membrane. Therefore, more attention should be paid during construction. Below are the precautions for using HDPE polymer self-adhesive film waterproofing membrane:

1. It is not suitable for construction when the temperature is below 5 ℃ or above 38 ℃, nor is it suitable for construction in rainy weather or wind energy above level 5.

2. It is necessary to ensure that the HDPE polymer self-adhesive film waterproofing membrane is aged for 10 days under natural environmental conditions. If the time is tight, it should also be aged for 5 days under steam curing conditions at 60 ℃. If the aging time is insufficient, coupled with shrinkage after the wall, it may cause cracking, warping, or deformation.

3. When pasting, if adjusting the flatness, please use a rubber hammer to strike and do not move left, right, up, and down to prevent the adhesive from overflowing into the gaps between the coils, forming a cold bridge and affecting the waterproof effect.

4. During the construction of the outer corners, the HDPE polymer self-adhesive film waterproofing roll should be appropriately extended to a certain distance outside the wall to ensure the verticality of the outer corners. After pasting all the films, uniform elastic line cutting can be carried out, and compression and flattening can be carried out.

5. After compacting the HDPE polymer self-adhesive film waterproofing roll, the flatness needs to be controlled within a certain range. If there is unevenness, it cannot be repaired by other methods.
