How to lay waterproof walls in the bathroom

The waterproofing project of the bathroom is the place where the current home decoration is more prone to problems, and special attention should be paid to the "sensitive areas" in these home decorations. At present, there are many kinds of materials used for waterproofing in toilets, and basically the waterproof effect is good, but it is necessary to pay attention to the specific construction details.

Make a flat floor. If you want to replace the floor tiles in the bathroom, after chiseling the original floor tiles, you should first level the floor with cement mortar and then do the waterproofing treatment. This avoids leakage of the waterproofing coating due to uneven thickness. The joints between the walls and floors of the bathroom and the joints between the water and water pipes and the floor are the most problematic areas.

During construction, the joints should be painted in place.

Treat the wall. In the general waterproofing treatment of toilets, the wall should also be coated with a waterproof paint about 30cm high to prevent water from penetrating the wall. If you use two screens, the two walls that are connected should also be painted. If you use a bathtub in your home, the wall adjacent to the bathtub should also have a higher height of the waterproof paint than the top edge of the bathtub.

Waterproof experiment. After the construction of the toilet is completed, all the sewers of the toilet are blocked, and a 25cm thick "threshold" is built at the door, and then 20cm high water is poured into the bathroom. After 24 hours, you will check the surrounding walls and floors for leaks.

The waterproof layer of the bathroom is very easy to be damaged during decoration, especially the joints between the sewer pipe and the floor slab are the most likely to leak, which will bring trouble to the residents on the lower floor. The traditional practice is a waterproof layer of two felts and three oils or three felts and four oils. In the decoration project, this kind of hot processing has been basically eliminated.

At present, most construction units use waterproof coatings. Although this is simpler than the construction procedure of two felts and three oils, there is a strong peculiar smell in the construction, and the floor pipe joint is slightly larger, which will cause hidden dangers. The best solution is to mix the cement mortar with waterproofing agent, with South Korea's "PSC Laoyal" waterproofing agent as the best, after the cement and sand are mixed in the ratio of 1 3, then mix with waterproofing agent instead of water, and then use the construction like plastering the wall and plastering the ground, which is simple and reliable, and will never produce cracks and aging.

If the bathroom is waterproof, waterproof wallpaper will not play a role, and it is recommended that you do it again again

1. Because your home is an old house renovation, the age of its own waterproof material is estimated to be not long 2If there is a shower area in the bathroom, according to the national regulations, the wall waterproofing is to return to the high meter, and the splash water in the bathroom will make the wall damp

Therefore, it is better to do waterproofing once, and it is more assured that waterproofing will not cost many meters
