matters needing attention
Do not lay self-adhesive coiled materials on the frozen base surface;
It is not allowed to construct on the polluted base course with high moisture content;
The packaging and separation paper of self-adhesive coiled materials can only be removed before and during paving;
When the sealant is not used up, the container shall be tightened and sealed in time;
Storage and transportation
Materials shall be stored in a dry and ventilated environment to prevent exposure to the sun and rain. Coils of different types and specifications shall be stacked separately.
The stacking height shall not exceed 5 layers, and the vertical stacking height shall not exceed 2 layers.
Under normal conditions, the storage date is one year (from the date of production).
