How to pay attention to the waterproofing of the bathroom and kitchen in the renovation

It must be re-waterproofed.

The floor of the bathroom must be all waterproof, and the wall must be no less than meters or full. With a 2-meter-wide and 3-meter-long bathroom, the waterproof area must be at least about 25 square meters.

The floor and wall of the kitchen also need to be waterproof, the ground must be full, the wall surface is not less than meters, and the wall placed in the washing basin is the best meter. Based on a 3-meter-wide and 4-meter-long kitchen, the area that must be waterproofed must be at least about 16 square meters.

The floor and walls of the balcony also need to be waterproofed, and like the kitchen, the floor must be full, and the wall surface must not be less than meters. Based on a balcony with a width of one meter and a length of 3 meters, the area that must be waterproof must be at least about 7 square meters.

In addition, if you live on the first floor, all floors and walls of the house (back to height meters), as well as all floors and walls in the basement, should be waterproof and moisture-proof.

The waterproof layer should be scraped and coated in accordance with the principle of first detailing (pipe roots, leakage holes, etc.) and then (wall and floor).

The yin and yang angles should be made into an arc shape, before the large-area waterproof construction, according to the design requirements, the sealing material should be embedded in the concave and convex grooves, and the gutters, gutters, yin and yang angles, pipe roots and other nodes should be painted twice with a brush.

The waterproof coating must be fully applied, without omission, and firmly bonded to the base layer. No bubbles, no cracks, no delamination, smooth surface, the height of the rolled up part is basically the same and uniform, and the thickness needs to meet the specified requirements of the product. The waterproof coating construction should be operated in accordance with the time, progress and step-by-step operation specified in the product manual, and other follow-up engineering construction should be carried out after the construction link is completely completed.

Wall waterproofing and joints, yin and yang corners, water pipes, floor drains and sanitary ware around and laying hot and cold pipes are key waterproof parts, but they are often ignored, once there is leakage will cause huge losses, so we should strictly and carefully check the construction of these places.

Re-brush waterproof, at least twice, the first time is completely dry, and then brush the second time, pay attention to the drain, but also brush well, the height is about 5-6cm

Have you finished tiling? If you finish tiling, you can only throw away the tiles and redo it, and you can do it again if you don't have tiles.

If it hasn't been concealed, just do it again according to the original waterproof material.

The original waterproof layer was destroyed, and the waterproofing had to be done again.

The waterproof material should be bought well...
