How to deal with the exterior wall of a stone house in the 90s? 75

1) It is not recommended to solve the leakage of the exterior wall of the new house, the main reasons are as follows: the search for the leakage point of the exterior wall may be relatively troublesome, especially in the case of no obvious damage to the exterior wall, self-treatment, which may cause damage to the exterior wall finishing layer treatment, insulation layer treatment, etc., and at the same time, because it is an outdoor aerial operation, it is likely to cause safety accidents.

2) If there is a leak in the exterior wall of the old house, it is recommended to find the property to solve it, the exterior wall belongs to the public part of the building, and if it is damaged, the property can use public maintenance ** for maintenance.

The first reason is that there is a problem with the waterproofing layer of the bathroom. In accordance with the relevant regulations, the house delivered by the builder should have a waterproof layer in the bathroom and kitchen, in order to avoid the failure or damage of the waterproof layer, the bathroom and kitchen floor should be checked for water storage during decoration, and the waterproof layer seepage must be re-waterproofed. At present, the waterproof material commonly used in home decoration is acrylic waterproof coating, which belongs to the coating film waterproof material.

Generally speaking, the construction of the waterproof layer on the ground should be painted in two layers, reaching a millimeter thickness according to the regulations, extending to the wall and 30 cm above the ground. The height of the waterproof layer on the wall of the bathroom near the shower head is not less than a meter. After the construction of the ground waterproof layer is completed, the water must be stored for 24 hours for the test.

Zhang Xiulian's house only achieves a height of 1 meter, which obviously does not meet the norms. Moisture passes through the capillary pipes in the wall to cause moisture and water seepage on the wall next door. This is also the reason why the back panel of Zhang Xiulian's wardrobe is deformed.

The second reason is that the water supply pipe is running, dripping, and leaking. There was a period of time when most of the water pipes used in home decoration were aluminum-plastic composite pipes. This type of pipe is produced using ultrasonic lap welding technology, and the aluminum interlayer thickness is different and the compressive capacity is low.

Moreover, the connection with the metal pipe fittings is easy to cause the water pipe to run, drip and leak due to thermal expansion and cold contraction; At present, PPR pipes are mostly used in waterway transformation, which not only has a longer service life, but also has stronger pressure resistance and high temperature resistance, and more reliable hot melt connection performance. After the waterway is reconstructed, the pressure test should be carried out to check that there is no leakage before the next process can be constructed.

Considering that the hardness of the stone material is not enough and it is easy to absorb water, and the plan for decoration is to restore the original appearance of the exterior wall, hook the joints, and spray a protective layer on the original stone wall (spray it directly on the wall with overprint paint). Based on these circumstances, it feels that it is better to use cyanide waterproofing instead of overcoat varnish. After the construction of the cyanide waterproof coating, it is colorless and transparent, which can maintain the original appearance of the stone, the surface is bright, and has a good waterproof effect, and can play a certain degree of protection against the hardness of the stone texture and easy to absorb water.

A small range of sample tests can be done to determine the comparison effect.
