What waterproof materials are needed for bathroom decoration? What are the main construction steps?

It is recommended that waterproof materials use polymer cement-based waterproof coating slurry, 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, especially suitable for the construction of many pipelines and small sites, and cement substrate bonding is tight, long service life, strong waterproof effect, moderate price and other significant characteristics. Choose big brands with good quality and good reputation, such as:

JCDecaux, Lei Bangshi, etc.

First of all, deal with the base surface (substrate) of the waterproof position. 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. Second, 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. 3. Pay attention to the position and height of the 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. Fourth, 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. Fifth, the later decoration should do a good job of protecting the waterproof layer to avoid damaging the waterproof layer.

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

JCDecaux waterproof universal type.

Features: It has the function of permeation crystallization, which can be used for positive and negative waterproofing.

Good adhesion to the base surface and high bonding strength;

Good water resistance, can be used in long-term immersion environment, such as pools, etc.;

The construction is simple and convenient;

Can be used on wet substrates;

Environmentally friendly and non-toxic. Construction technology:

Use a brush, roller or batter to evenly spray the mixture on the damp substrate and carefully inspect for any defects or holes.

Generally, it is necessary to apply more than two layers. The second layer can be carried out in about 1-2 hours after the first layer is coated, when the first layer is not completely dry, but the hand touch will not fall off, at this time there will be the best combination between the two layers. If the first layer has dried completely before proceeding to the second layer, spray a small amount of water before finishing.

The thickness of a single brush shall not exceed 2mm, which is conducive to curing and curing.

When doing the second layer, the direction of the brush should be at a 90-degree angle to the first layer to achieve the best coverage.

After the construction is completed, it is forbidden to step on it within 24 hours, and the next process is carried out after all the waterproof layers are completely dry.

It is forbidden to use in an environment below 5 degrees Celsius.

Avoid construction in high temperature and dry environments.

Dosage: Moisture-proof ground and exterior walls, dosage per square meter;

Bathrooms, sinks and still water under pressure (negative waterproofing), dosage per square meter;

High hydrostatic pressure (negative waterproofing), dosage per square.

Specifications: Color: Green.

Bathroom waterproofing, it is recommended to use kitchen and bathroom waterproof slurry, it is specially developed for the most leaking yin and yang corners, pipes, sanitary ware, floor drains and other peripherals, and the use of key parts of the repair first, and then the overall rental waterproof concept, so the waterproof effect is better than the general waterproof material.

Main construction steps:

Clean the base surface, sprinkle water to moisten but do not accumulate water.

Prepare the quick-setting repair mortar, add water to the quick-setting repair mortar according to the ratio of 3:1, and the adjusted mortar needs to be used up within 5 minutes. The quick-setting repair mortar is evenly brushed on the yin and yang corners, pipes, sanitary ware, floor drain periphery and other parts that are prone to water seepage.

Pour the waterproof liquid and powder into the bucket, then stir evenly with an electric rod, let stand for 3 minutes and stir again for later use.

Paint waterproof coating, the bathroom floor needs to be done, the wall needs to be painted at least to the meter, it is recommended to do the full height. Brush 2-3 times, the total thickness is in.
