How to remedy the low waterproofing of the bathroom wall

1. Inspect and accept the appearance, variety, specification, packaging, size and quantity of materials, and form corresponding acceptance records.

2. Check the quality certification documents of the materials and include them in the engineering and technical files.

3. After the material enters the site, the material inspection report shall be issued according to the specification.

4. When all the indicators of the physical properties of the material meet the standards, it is qualified; If an index does not meet the requirements of the standard, the index should be re-sampled in the tested product for re-inspection, and the re-test result meets the requirements of the standard, and the batch of materials will be judged to be qualified.

5. Waterproof material. There are three main categories: waterproofing membranes; 911 polyurethane waterproofing material; New polymer cementitious waterproofing material.

The last category is divided into general-purpose GS waterproofing materials and flexible JS waterproofing materials. Among them, the universal waterproof material is suitable for the waterproofing of the indoor floor and wall of the family.

How high do you waterproof your bathroom? Is there a water leak now? What tiles are used? It is better to add a few photos of the bathroom (four walls).

First of all, the bathroom is waterproof, the standard practice is that the ground needs to be done all, the wall should be at least meters high, it is recommended to do full height, if it is a light wall, then it must be done full height.

Secondly, if the waterproof height of the bathroom wall is low, and there is no tiling yet, you can re-use the waterproof slurry of the kitchen and bathroom to do waterproofing in the area above, but if the tiles have been pasted, it is recommended to pay more attention to the shower in the future, so as not to leak prematurely.

Generally do rice、In order to be a little more safe from the bottom。

What is the current situation? Have you just received the house, or have you already put bricks on it?

The bathroom is narrow, and there are pipelines passing through the floor, so coatings are commonly used for waterproofing.

There are two common types of coating waterproofing: synthetic polymer --- polyurethane waterproof coating (polyester cloth and glass fiber cloth are added to corners, etc.), polymer modified asphalt--- SBS waterproof coating (carcass reinforcement material, polyester cloth, glass fiber cloth, etc.) asphalt-based waterproof coating is basically not used.

The practice of polyurethane waterproof coating is as follows:

1: The ground is facing the slope of the floor drain direction, cement mortar or bean stone concrete can be, but the surface should be smooth. The slope near the door is small, and the slope near the floor drain is large, so you can grasp it according to the specific situation.

2: The pipeline passes through the root of the floor slab to strengthen the waterproofing. After the pipe root building sealing paste is sealed tightly, and the cement is smoothed and the foot pads are smoothed, the glass wire cloth reinforcement layer is 1 or 2 layers when brushing the waterproof coating. The same measures are taken near the floor drain.

3: The wall is clean and flat, without floating ash and small particles, and the junction of the wall and the ground is wiped with small original corners or slope corners. When brushing waterproof coating, paste 1 2 layers of glass wire cloth reinforcement.

4: The total thickness of the polyurethane waterproof coating film is required to be more than millimeters. It can't be decided by the number of passes.

The pipe root and the corner of the reinforcing layer are brushed first, and after the surface is dried at room temperature for 4h, then a large area is brushed and scraped. There shall be no leakage and bubbling. Brush a large area for 24 hours and then apply the next layer after curing.

6: The waterproof layer on the ground should be painted 300 wide outside the door of the bathroom. The waterproof floor waterproof layer should be 200 above the ground, and the wall waterproof layer of the bathroom with shower should be 1800 above the ground (L8 recommends waterproofing the full wall).

7: Do the closed water test according to the requirements (the closed water test method is omitted).

8: There is a package riser practice (package riser method details l8 old post), it is recommended to do the waterproof and then do the package riser, and then make up the waterproofing locally, if the ground waterproof layer is not damaged, you can avoid the closed water experiment.
