All Lao Li's waterproof process: ground leveling--- waterproof layer 1 (300 high) - cushion (buried pipeline and slope at the same time, commonly used light aggregate concrete or coke slag - due to less coal burning, coke slag is not easy to find) - leveling layer--- waterproof layer 2 (connecting the wall 1800 high, it is recommended to fill the wall) - leveling layer (protective layer) - facing layer (ground tiles). If it is done in one step, the penultimate leveling cover and the cement mortar for the floor tiles are combined into one.
If you do stone-plastic flooring, etc., you should make the second-to-last leveling protective layer, and paste the "stone-plastic flooring" after the end. This kind of cushion has pipelines in the practice, after the construction of each waterproof layer, to do a closed water test, after the completion of the surface layer, it is recommended to do it again. The purpose of the two waterproofs is not the same:
The lower waterproof layer is to prevent the rupture and leakage of the pipeline in the cushion, especially the old three-way drain method of buried sewer pipes. The upper waterproofing layer is to prevent the normal use of surface water leakage.

Anonymous users2024-01-23Generally, there is a 10cm cement mortar protective layer under the bathroom floor, which will not damage the waterproof layer, but if the rough construction, or the master does not do enough thickness of the protective layer after painting the waterproof layer, it is easy to destroy the waterproof layer, no matter how much the waterproof layer is damaged, it is extremely difficult to repair the old waterproof layer to achieve a good waterproof effect, in order to avoid water leakage and water seepage in the future, the most thorough protection method is to redo the waterproofing.
Specific construction methods:
Remove the old waterproofing layer from the ground as much as possible; Knock off the tiles at the baseboard to expose the old waterproof layer of the wall10 or so; Use cement mortar (cement: sand = 1:2) to level the ground, so that the leveled ground is flat, firm and clean, without cracks and pores, etc.; It is recommended to use Jiashi multi-plugging king or nozzle grouting material for nozzle filling; The corners of the wall should be plastered into an arc shape (or V-shaped); Make sure the base surface is well moistened, but there is no open water.
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 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;
Prepare the polymer cement-based waterproof coating according to the product instructions. 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 brush is carried out (just non-sticky, generally 1-2 hours apart), and the front and back two vertical cross brushes, 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. When painting the ground, there should be about 10 overlaps with the old waterproof layer of the exposed wall.

After the water circuit transformation is completed, you can do it before tiling, and remember to do a 48-hour closed water experiment after you finish it.
Personally, it is recommended to use Guoerjia acrylic waterproof coating, combined with reinforced polyester cloth, and implement the construction process of three coats and one cloth or four coats and one cloth, so that the effect can achieve the ideal appearance and no leakage for more than 30 years.
The bathroom must be waterproof, if the wall of the bathroom is the outer wall of the building, that is, there are no neighbors, then the side wall is also best waterproof to prevent the return of moisture in winter.
Generally, the waterproofing of the bathroom is done after the floor heat is paved, and the water pipe should be sealed with cement when the floor heat is paved, including the water pipe of the bathroom. When collecting the house, you need to do the water test of the kitchen and bathroom, and the waterproof test can be divided into two times or three times when the bathroom is renovated, the first time the caisson floor is cleaned up and done once, and then after air drying, the second flooding slope is done, and then the third time is done after drying, and then filled with ceramsite after air drying, and then cement sand leveling, and then the bricks are paved.
Silicon PU is a kind of ergonomic principle and meet the needs of sports physical characteristics, with the characteristics of hard and elastic structure and can be directly constructed on the basis of cement or asphalt on the basis of a healthy professional elastic synthetic stadium surface material system, with a one-component silicone modified polyurethane to form a buffer rebound structure, two-component modified acrylic as a wear-resistant surface layer, by Jiangmen Changhe Group in January 2005 successfully developed, and named "silicon PU".
