Construction precautions

Grassroots treatment: Before construction, the base should be thoroughly cleaned and treated to ensure that it is flat, clean, free of oil stains and loose materials.

Laying technique: When laying asphalt glass cloth felt, attention should be paid to the overlap width and overlap method between the rolls to ensure a tight bond between the rolls and the integrity of the waterproof layer.

Temperature control: During the construction process, the temperature and viscosity of the asphalt should be strictly controlled to ensure that the asphalt can be evenly coated on the fiberglass fabric and form a good bonding effect.

Post maintenance: After construction is completed, necessary maintenance and protection should be carried out on the waterproof layer to avoid damage or destruction.
