How to maintain local water leakage in rainy season?
Local water leakage mainly depends on which part leaks, such as moldy putty layer and leaking pipe root.
In this case, only local repairs are needed, such as removing the original surface layer, protective layer and waterproof layer, slotting the pipe root, embedding the water stop, wiping the arc with a rain rainbow, then re-waterproofing, and restoring the surface layer after passing the closed water test.
What is the waterproof construction process of the new house?
Waterproof construction of new houses is generally divided into the following steps:
Waterproofing is done, and it usually needs to be brushed 2-3 times. After the first waterproofing, if water leakage is found in the test, we must first find the water leakage point and the reason. Balcony, roof and kitchen, wall and ground, scene leakage and general leakage are all different. Choose different maintenance schemes according to different situations. Three points for materials and seven points for construction. According to different situations, select corresponding waterproof products for secondary waterproof reinforcement.
If the new house is waterproof, will it not leak in the later period?
Waterproofing in the early stage can only ensure that there will be no water leakage under normal circumstances. If some external factors lead to the rupture of the waterproof layer in the later period, water leakage will also occur. And waterproof layer rupture, generally there are three reasons:
1. After the new house is completed, there may be different degrees of settlement of the building structure in a few years. In the process of settlement, there may be fine cracks in the building, which may be caused by external forces.
2. Newly-built buildings are prone to slight structural deformation and micro-cracks at the grass-roots level due to cement hydration, which damages the waterproof layer;
3. After the waterproof layer is finished, it will face a series of processes such as sticking bricks, which may cause slight damage to the previous waterproof layer, thus causing micro-cracks in the waterproof layer.
Will the tiny cracks in the house definitely lead to the rupture of the waterproof layer?
Cracks in the building may not necessarily lead to the rupture of the waterproof layer, but whether it will rupture depends mainly on the tear resistance of the waterproof coating. For example, Yuhong 300 self-repairing waterproof coating has super tear resistance, and the tear strength is 18- 19N/mm, which is equivalent to polyurethane waterproof coating and far exceeds the tear strength of 9- 10N/mm of other brands at the same price. Using this waterproof coating, the waterproof layer of buildings is not easy to break.
What is the difference between self-repairing waterproof coating and ordinary waterproof coating?
Self-repairing waterproof coating adopts self-repairing technology, which is a patented technology of Yuhong waterproof, and its repairing principle is as follows:
1. Waterproof coating contains many special components, which can form gel after absorbing water and repair damage. This repair factor is the main factor that the product has self-repair function;
2. The polymer in the coating film has excellent flexibility at low temperature, and the viscoelasticity of the polymer is mainly reflected in the viscosity at room temperature, and the molecular thermal movement speed is fast. After the damage, the polymer components in the coating film are bonded together again because of the viscosity shown by molecular thermal motion, which plays a role in repairing;
3. After the film is formed, the product will swell to a certain extent in water or wet environment, which will narrow the cracks and promote the repair.
What is the safety and environmental protection of self-repairing waterproof coatings?
We judge the environmental protection of a waterproof coating mainly by its environmental certification and TVOC release. Yuhong 300 self-repairing waterproof coating has passed the environmental protection certification of German EC and is one of the highest environmental protection standards in Europe.
TVOC is one of the three kinds of pollution that affect indoor air quality. It exists in the air in the form of evaporation at room temperature. It is toxic, irritating, carcinogenic and has a special smell, which will affect the skin and mucosa and cause acute damage to the human body.
The TVOC release of this product within 28 days is1150 ~1/200 of similar products on the market, and its TSVOC release is less than 5 μ g/m3, which is almost the limit value that can be achieved by current technical means, and the VOC of the product is infinitely close to zero. Therefore, in terms of environmental protection, it is still very secure.
Are there any special requirements for repairing waterproof coatings during construction?
Without special requirements, the construction difficulty of workers can be greatly reduced. Because the self-repairing waterproof coating adopts special dispersion technology, the dispersion speed of powder in liquid material is improved, and the construction is smoother and more efficient.
Wide application range, suitable for waterproof, moisture-proof and exposed roofs of bathrooms, kitchens, balconies and other floors and walls during renovation of new houses.
In addition, what problems should be paid attention to during construction?
1. During construction, the temperature should be between 5-35℃, and outdoor construction is prohibited in windy or rainy and snowy weather;
2. The prepared waterproof coating should be used within 1 hour, and it is forbidden to add water again when painting;
3. It is forbidden to add water or any other materials during the batching process;
4. Pay attention to protect the waterproof coating from damage during construction.
