2. Qualification standard: The waterproof coating film on the bathroom floor and wall (non-additional layer part) is well formed and has no delamination. The average thickness of the waterproof layer of the coating film should be in line with the design, and the minimum thickness should be greater than the design thickness
3. Measuring tools: vernier caliper, 5m tape measure.
4. Measurement methods and data recording:
1) Measurement area and pass rate calculation point: every 1 bathroom is 1 measurement area, a total of 6 measurement areas, when less than 6, the number of measured suites needs to be increased. One measured value is taken for each measured area. Each measured value is counted as 1 counting point.
2) Measurement Method:
In the construction stage of the coating film, in the same measurement area, within the range of non-additional layers, select one part with the thinnest suspected thickness, use the needle measurement method or cut 20 20mm real samples, visually inspect the film formation and delamination of the coating film, and measure the thickness with calipers;
In the completion stage of the protective layer, in the same measurement area, within the scope of the non-additional layer, randomly select a point (different locations are selected in different measurement areas, such as different high positions on the ground and bathroom walls, etc.), peel off the waterproof protective layer, use the needle measurement method or cut 20 20mm real samples, visually inspect the film-forming and layering of the waterproof coating film, and measure the thickness with calipers;
If the decorative surface has been finished, it will pass the closed water test and do not measure this index.
3) Data recording: when the waterproof coating film slice of a measurement area is found to have no film-forming or delamination, the measured value is unqualified; When the slice thickness is less than 80 of the design thickness, the measured value is unqualified; When there is no delamination and the thickness meets the requirements, it will be counted as qualified; Unqualified tap 1 to record, pass tap 0 to record. 5. Examples:
A total of 1 household, 2 measurement areas, and 6 measurement points).
Now the bathroom waterproofing is basically used, waterproof coating: polyurethane waterproof coating, waterproof membrane: polymer self-adhesive waterproof membrane, cross membrane waterproof membrane. Polypropylene cloth is not recommended because it has little crack resistance. It will be easy to leak now.
The kitchen and bathroom floor bai degree is constructed according to the design requirements, and according to the ground >>>More
The coating film has no waterproof effect in the case of not being able to resist drying, the role of coating film waterproofing is to overcome rigidity with softness, seal capillary pores and micro-cracks, no matter what the reason is sprinkled with dry ash on the paint that has not dried, it is also wrong, the microscopic view is obvious that the waterproof coating structure is destroyed, and the paint ratio is the same, resulting in a decline in flexibility, not a film, in the waterproof at least 24 hours after the completion of the coating film, the surface is useless. In this case, the landlord has not considered the water storage test 24H, just go into the search Qi to take the next process construction, it is not desirable, the conventional 24 solid wall is not needed 180CM as long as 50CM can be, of course, if the effect is better, the 12CM partition wall is required 180CM height, the wall also needs to be drenched in the water test, dry after the wall paint is painted 5 times, and the last time must be sprinkled with dry cement sand while the paint is painted, and the roughness is built, and the tiles are easy and reliable. The waterproof layer of the bathroom is formed at one time, the overall fortification, and there is no waterproof layer to do after the tiles, which is deceptive.
According to the understanding of the home improvement waterproof industry, it seems that impermeable membranes will not be used in the bathroom now, and cement-based coatings are used to meet the needs of waterproof, moisture-proof and leakage-proof.
45-65 yuan per square meter, depending on the region and materials.
