If you want to help the room to carry out moisture-proof, you can take a variety of waterproof coatings, among which pvc waterproof board is more, and what is the construction scheme of pvc waterproof board? When using such waterproof coating to carry out the construction, it is also necessary to consider what matters needing attention in the construction of pvc waterproof board to ensure the construction effect.

pvc防水板施工有哪些注意事项?

First, pvc waterproof board construction plan

1, before the construction, remove the dirt and slag on the bottom surface, the bottom must be cleaned up, the surface is not sharp objects, and then the project acceptance, all qualified again gradually construction.

2, first pave a layer of polyethylene plastic, polyethylene plastic lapping with self-adhesive strips to carry out bonding, so that the construction will be more convenient.

3, pavement flame retardant plastic foam plastic thermal insulation material, with special standard parts fixed heat insulation board.

4, prelay pvc waterproof coil, pvc waterproof coil according to the payout control position is set on the heat insulation layer, pavement bearing and press plate wavy vertical, of course loose pvc waterproof coil is set on the heat insulation layer according to the wheel gallery. The waterproof coil must be smooth and flat. It cannot be distorted. The total width of the lap joint should be 120mm, and appropriate cutting should be done.

5. The pvc waterproof coil is fixed. Standard parts and gaskets are fixed 30mm from the edge of the waterproof coil along the identification line.

6. Waterproof coil lapping: a pair of pvc waterproof coil is lapped on another piece of pvc waterproof coil, so that standard parts and gaskets are covered under the waterproof layer. Weld each lap edge with automatic welding electromechanical welding. If double welding is taken, air test is required.

7, the connection point solution: cut appropriate pvc waterproof coil plastic plate corresponding to the connection point, the selection of portable welder plastic plate electric welding on the large surface of pvc waterproof coil.

8, to develop pvc waterproof coil closing, the closing part of the selection of decorative strips to carry out fixed, must pay attention to the sealant to help fixed.

Second, what are the precautions for the construction of pvc waterproof board

1. Pavement pvc waterproof coil needs to pay attention to the construction working temperature. The application environment temperature of waterproof coil should be about -5℃, and if full adhesion method is selected for construction, the application environment temperature of pvc waterproof coil should be about 5℃.

2, when paving pvc waterproof coil, solve some special parts to do additional layer. Then the construction and maintenance should be carried out every day before the end of the construction should be temporarily fixed pvc waterproof coil, to prevent it from being blown away.

3, the construction of waterproof layer should be carried out after the completion of the upper process, no construction steps can not cross, to prevent the impact on the actual effect of construction. If you need to assemble some machinery and equipment on the roof of paved pvc waterproof coil, it needs to be solved in the basic part of the machine for additional layer, such as the need to build a high waterproof layer, you need to check and accept the waterproof layer project, to be accepted after acceptance.
