Here is a breakdown of the problem of home improvement waterproofing:
The first is the selection of waterproof materials. At present, there are many kinds of waterproof materials used in home decoration on the market, but there are no more than two categories: hard and flexible. The hard waterproof material is represented by waterproof mortar, and the flexible waterproof material is represented by polyurethane. These two types of waterproof materials are currently the mainstream products used in the home improvement field, and there are many other types of waterproof materials, such as coils, non-woven fabrics, and other waterproof materials. I will not go into details here.
The two major types of waterproof materials currently used in home improvement give you talk about their advantages and disadvantages:
1. Hard waterproof material (some people call it rigid), has the advantages of non-toxic, odorless, simple and quick construction, but it does not crack, in case of related changes in the building due to settlement and other reasons it will crack lead to leakage, the general stability Slightly inferior brick-concrete structures, kitchens with non-load-bearing walls, and guards should not be used as much as possible.
2. Polyurethane type flexible waterproof material also has the advantages of simple and quick construction. Due to its good flexibility, its anti-fission function is particularly prominent. It is applicable to any structure of the building, and must be applied to the coating film. Divide it over and over again (requiring more than three times), it is not possible to thicken the coating film in order to save time and reduce the number of passes. The thickness of the coating film should not exceed 0.5 mm each time, and the total thickness of the coating film layer should not be less than 1.5 mm. Polyurethane flexible waterproof material is inadequate in terms of taste and toxicity.
3. The above two kinds of waterproof materials If you have strong hands-on ability, you can refer to the manual DIY yourself, do not regard the waterproof thing as an unattainable high-tech, in fact, hanging blocks of meat dogs will do! And can save about 100 yuan per square meter of expenditure.
Precautions before home construction waterproof construction:
1. Inevitably, when the kitchen and toilet hydropower is reformed, there will be ground slotting and redistribution of water pipes. We remind everyone that the groove of the ground will cause damage to the original waterproof layer. For safety reasons, I suggest that everyone should first After doing waterproofing and then cloth pipeline, remember that: after the transformation of the water pipe must be pressure test, the pressure of 6-8 kg, within 10 minutes, no obvious discontinuation of the table as qualified.
2. The grooving of non-load-bearing walls should take into account the infiltration of condensed water condensation in the tap water pipe in summer. It is better to go to the place where the waterproof material is to be sold and buy some water pipe jackets to wrap the water pipe and then seal it to prevent condensation of the water pipe. Infiltration of the outer wall, some people think that this move is a lot of things, but the old Zhang taught you is a foolproof trick, listen to you!
3. Before applying the waterproof material on the surface of the grassroots, dust and other debris should be cleaned. The residual grout and the high part of the surface should be leveled as far as possible, and the brush should be cleaned with emphasis on the difficult-to-clean parts around the pipe root. Departments, yin and yang corners should be rounded.
4. Waterproof construction can be carried out after careful inspection. If the non-load-bearing wall is a shower wall, the waterproof should be made as high as possible. The other walls can be checked by water resistance from the ground by 30 cm.
1. Closed water test is the most effective and effective means of verifying that waterproof is good or bad. It will temporarily block all the water outlets and doorways of rooms that are waterproof, and put it into an inch or so of deep water. Called closed water test. The national standard is based on the inspection after 24 hours, but personally think that the longer the more it can test the quality of waterproof construction, it is best to 48 hours after the inspection to the same location downstairs whether the roof is dripping, dampness and other phenomena, through At the end of observations such as listening and watching, it was found that the above phenomenon indicates that the waterproof is qualified.
2. The above inspection of the owner is best to participate in, sign after passing, be aware of.
