Bathroom waterproofing project, how to do toilet waterproofing project

First of all, choose a waterproof material that is suitable for home decoration. It is recommended to choose the polymer cement-based waterproof coating slurry commonly used in home decoration, that is, the name on the market is: general-purpose, flexible, K11, JS, GS waterproof coating slurry, this kind of product is water-based coating, non-toxic, harmless and pollution-free, simple and fast construction, and cement substrate bonding tightly, long service life, strong waterproof effect, moderate and medium significant characteristics.

A brand with good quality and good reputation.

Clause. Second, the base surface (substrate) of the waterproof position should be treated. The base surface is treated into a firm, flat and clean surface, free of dust, greasy, wax and other debris substances; If there are pores, cracks and unequal defects on the base surface, it must be repaired and smoothed with cement mortar in advance, plastic strips are recommended to be pasted on the expansion joints, a layer of non-woven fabric must be added to the node, and the nozzle is recommended to use plugging king or nozzle grout; The corners of the wall should be plastered into an arc shape (or V-shaped); Make sure the base surface is sufficiently wet, but there is no open water;

Clause. Third, pay attention to the waterproof construction in place. Use a brush or roller brush to apply directly to the base surface, and the strength is used evenly, and the brush should not be missed; Generally, it needs to be brushed twice (according to the requirements of use), and the thickness of each brush should not exceed 1mm; After the previous one is slightly dry, the next one is brushed (just non-sticky, generally at an interval of 1-2 hours), and the front and rear vertical cross brushing, the total thickness of the brush is generally 1-2mm; If the coating has already cured, moisten it with water first when applying another layer.

Special attention should be paid to the corner part of the wall to be treated into an arc type and then painted, and the painting can not be too thick (the total thickness does not exceed 2); The pipe through the wall should be sleeved with a casing, and the holes of the casing and the wall should be filled with a plugging king, and the waterproof material should be brushed to the height of the casing 10 and not too thick;

Clause. Fourth, pay attention to the position and height of waterproof painting. Ground; Generally, the wall is repainted and brushed 30 high; Paint the wall around the shower area 180 high or to the top of the wall; There is a bathtub where the upper brush is 30 higher than the bathtub.

Clause. Fifth, do a good job of water test. After the waterproof coating is painted to form a waterproof layer (about 24 hours later), the water storage is 20 high, and after 24 to 48 hours, see if the water is significantly reduced or go downstairs to see if there are wet water spots on the roof, and if not, it means that the waterproof construction is successful.

Clause. Sixth, the later decoration should do a good job of protecting the waterproof layer to avoid damaging the waterproof layer.

If you do the above six points completely, you will definitely be able to achieve the waterproof bathroom without any "wet".

Make the hole first, after it is done, install the pipe, backfill and level, and do it again. The waterproofing of the bathroom is still relatively simple.

Masons do a good job of the floor, buy a good waterproof coating, brush twice, the next day put water on the floor, soak for a day, if the water is not less than the waterproof is more qualified.

1. Treatment of the grassroots:

First clean the wall and floor of the bathroom, carefully check the wall and floor, if you find holes, sand, etc., you need to use the corresponding grade of cement mortar to re-repair the ground and face. Ensure the strength of the ground, in addition, before the waterproof construction, be sure to ensure that the bathroom floor can not have any dust.

2. Strengthen the handling of weak links

First, use waterproof mortar to wipe out a figure-eight waterproof platform at the root of the pipe, and use this method to treat the whole thing. Then use waterproof mortar to paint these weak links in advance, at least twice, to ensure that the waterproof mortar on the brush is tight and there is no leakage.

3. Waterproof large-area construction:

After the weak links are treated, you can start the construction of large-scale waterproofing of the bathroom. We have to keep in mind that the waterproof paint should be applied three times as required. For the first time, all the places that need to be waterproofed, walls, and floors should be fully brushed in place.

Then wait for the first coat of waterproof paint to solidify, and then proceed to a second large area of waterproofing. When the waterproof paint applied for the second pass is dried and solidified, the waterproof paint for the third pass is finally applied. When applying waterproof paint, be sure to press it again and again.

Paint them sequentially, so that no part of the waterproof paint is missed.

4. Closed water test:

The method of the closed water experiment is to block all the pipe openings in the bathroom and fill the bathroom with water. Wait 24 hours for observation, and it is recommended that you wait 48 hours before coming back.

What materials are used for waterproof toilets 1, cement slurry is reasonable, waterproof effect is good, is currently very popular with the preparation of a bathroom waterproof material. Toilet waterproofing material is an emerging waterproof material, but when choosing, we should pay attention to the solidity of sand and gray.

2. The acrylic bathroom waterproof material is colorless and odorless, which is used to achieve the purpose of waterproofing through the condensation film of the material, which has good ductility and elasticity, and is also a good toilet waterproof material. However, the cost of this type of material is higher, so the choice should be cautious.

3. Polyurethane waterproof coatings are mainly liquid, which are divided into two types: tar type and non-tar type. The non-tar type is mostly used, which is to use non-tar substances as curing agents, such as curing agents composed of asphalt, additives and fillers. This material has stable quality, stable cavity and rolling track, low pollution, good aging resistance, good adhesion and water enhancement.
