The threshold of the toilet and the outer wall of the water pipe are difficult to prevent water, and the toilet with poor construction quality is prone to water seepage at the two places.
Chinese patent No. CN103147547B discloses a waterproof construction method for toilet, which comprises the following steps: (1) cleaning the wall and ground base layer of the toilet; (2) cleaning the root parts of the upper and lower water pipes and performing plugging treatment; (3) pasting the contour line by the masking paper; (4) coating waterproof emulsion and drying for 18-24 hours; (5) painting waterproof emulsion for the second time, and drying for 18-24 hours; (6) after the surface cement mortar is napped, the ceramic tile is stuck. The waterproof construction method for the toilet is simple to operate, good in waterproof performance, and free of leakage within 48 hours, and the water discharge height is 30-50mm in a 24-hour water closing test.
The toilet waterproof construction method carries out leakage stoppage treatment on the root of the water pipe so as to prevent water flow from leaking from a gap between the outer side of the water pipe and a cement ground. However, the leak stopping treatment is usually performed by plugging the gap with waterproof concrete, and after the waterproof concrete is used for a long time, the bonding capability of the waterproof concrete is reduced, and the gap is easily generated between the waterproof concrete and the outer wall of the water pipe, so that the water seepage phenomenon exists, and the long-term waterproof effect is poor and needs to be improved.
