Answer:
1. The surface must be thoroughly prepared—it is often found that there are remnants such as template chips, iron wire, loose stones, and floating debris; if these are not treated, the effect is greatly reduced.
2. The corners must first be reinforced; the concept of reinforcement is divided into two types:
- Structural reinforcement.(Increase the water pressure or the bearing capacity of the covering layer)。
- Reinforcement of the waterproof material.(Layered effect, increasing tensile strength and elongation)。
3. The bonding function of reinforcement materials and waterproof materials.
4. The end of the waterproof layer must be treated properly.
- Coating waterproofing material ── Substrate coating, thickness control.
Baked and thin-sheet waterproof material — Metal edge sealing strips are used to fix the material and seal the seams.
