How to use self-adhesive waterproofing membrane?
7) on the interface seal: the use of additional self-adhesive seal seal. When sealing the interface, first remove the diaphragm on the surface of the membrane overlap parts, and then paste the additional self-adhesive seal. If the overlap is contaminated, clean it first. (When the upper and lower layers between the use of lap, no self-adhesive seal, lap width of not less than 60mm)
8) Self-adhesive waterproofing membrane in the wall when the paving, the coil should be temporarily sealed at the mouth (available tape or thickened cement slurry seal), to prevent the wall of the head of the water too quickly lost.
9) node to strengthen the processing: node in the large surface after the completion of the construction of reinforced processing.
4) shop self-adhesive waterproofing membrane: the self-adhesive waterproofing membrane tile in the cement waterproof mortar. The web is parallel to the adjacent web, and the joints should be made as far as possible. (When the lap mode is used, the upper surface of the lower layer is separated from the upper surface of the membrane and the upper surface of the upper membrane is removed and then overlapped.
5) beat the surface of the membrane, mention pulp: with a wooden trowel or rubber plate tapping the surface of the coil, mention pulp, discharge the membrane under the surface of the air, so that the membrane and cement mortar close fit.
6) to put on: dry for 24 hours to 48 hours (depending on the specific time depending on the ambient temperature, under normal circumstances, the higher the temperature the shorter the time required).
1) grass-roots treatment: grass-roots surface should be treated first, so that the grass-roots solid, clean, and fully moist, no water.
2) wiping cement (waterproof) mortar: its thickness is generally 10 mm ~ 20 mm (depending on the level of formation may be), paving should pay attention to compaction, smoothing. In the corner, should be wiped into a radius of 50mm or more fillet. Paving the thickness of cement mortar than the length of the coil, short side should be wide out of 100 ~ 300mm, and in the process of spreading the use of rail to ensure smoothness.
3) peel off the self-adhesive waterproof membrane under the surface of the isolation film.
Second, the cement mortar paste self - adhesive waterproofing membrane (mainly applicable to the basement is not leveling the basement roof, roof and other waterproofing works.
1. Cement mortar with the wiping paste self-adhesive waterproofing membrane
Construction process: grass-roots treatment - → wiping cement (waterproof) mortar - → peel off the self-adhesive waterproof membrane under the surface of the isolation film - → shop self-adhesive waterproofing membrane - → tapping the surface of the membrane, mention pulp - → (24 hours to 48 hours) - → on the interface seal - → node reinforcement - → quality acceptance
Construction Technology of Double - sided Self - adhesive Waterproof Coil
First, the empty shop self - adhesive waterproofing membrane (mainly applicable to the basement floor and other suitable for the empty parts of the waterproofing works.
Construction process: grass-roots treatment - → node strengthening treatment - → empty sheet - → long, short side lap bond - → quality acceptance
1) grass-roots treatment: grass-roots should be smooth, solid, no clear water, the grass-roots protrusions clean.
2) node to strengthen the processing: the node at the regulatory requirements to strengthen the treatment.
3) empty shop coil: coil length, short side of the overlap width of not less than 60mm.
4) long, short side lap bond: the length of the coil, short lap edge of the isolation film removed,
5) Adhesive on polystyrene board protection
