1. How to budget the amount of waterproof material used?
The amount of waterproof coating = waterproof construction area * the amount of paint per square meter.
2. What is the amount of single square meter for all kinds of waterproof materials?
According to the instructions of the various types of waterproof coatings of Yuhong brand, the 1.5MM thick coating requires the theoretical budget of the material as follows:
(1) Acrylic, 3 kg/m2 per square meter
(2) Polyurethane: the dosage is about 2 kg / m2
(3) Polymer polymer: the dosage is about 3 kg / m2
(4) Flexible cement mortar: the dosage is about 3 kg / m2
3. What should I pay attention to when purchasing waterproof materials?
At present, the management of building materials market is not standardized. There are many fake and inferior products on the market. When purchasing, you should choose relatively well-known brands. The real environmental protection waterproof material should have ten ring certification or CTC environmental certification and product certification.
In addition, pay attention to the manufacturer's service measures when purchasing waterproof coatings. Generally, regular manufacturers will have relatively standardized pre-sale, sale and after-sales services when selling products.
4. Why do you recommend to the building materials supermarket to buy materials?
The products in the general building materials supermarket, the price is clearly marked, the supply is relatively regular, so the products are not prone to counterfeit and shoddy products, and the disputes such as return and exchange are relatively better.
5. What is the price/performance ratio of various waterproof materials?
All kinds of waterproof coatings sold on the market, as long as they are products that meet the national standards, should be used as waterproof for home improvement. These coatings have their own advantages and you can choose to buy them according to your needs. Polyurethane waterproof coatings have good elasticity and extensibility. In terms of film quality, they are the most comprehensive in all kinds of coatings, but the construction period is longer and the price is more expensive. It is worth noting that most of the miscellaneous products currently on the market are not pure polyurethane, and the environmental performance is not very good; acrylic waterproof coating, convenient construction, environmental protection, film performance is also good, the price is moderate, the general home decoration waterproof will use this type Coating; JS is a waterproof coating with softness and softness. It is convenient to construct, environmentally friendly and non-toxic. It is also a good choice. Waterproof mortar coating has high film strength and good bonding with the base layer. It can be directly pasted with tiles, which is economical and practical. However, because it is a rigid waterproof material, it is not suitable for the renovation of new houses that may have settlement.
In general, among the various types of coatings, the best performance is polyurethane, the most cost-effective is acrylic and JS coating, while the mortar coating is economical and practical.
6. What are the main considerations for purchasing materials?
The first is waterproof performance, then environmental performance. Waterproof is a concealed project. After waterproofing, it is tiling. If toxic materials are used, it is like “gas bomb†buried in Canada. It will release poison gas for a long time, and it is difficult to re-replace it. Therefore, the environmental protection of materials is also A very important aspect of purchasing materials.
7. How can I buy environmentally friendly waterproof coatings?
Go to the formal building materials city (supermarket) and purchase environmental protection and quality certification products that have passed the China Environmental Labeling Certification and CTC products.
8. What is the easiest way to identify true and false waterproof coatings?
First look at the packaging, whether it meets the requirements of the brand's outer packaging, the color is clear, the writing is clear, according to the specification, the product name, net weight, description of the origin, certificate and other requirements. Most well-known brands have their own anti-counterfeiting labels. Pay attention when buying.
9, buy polymer polymer materials to guard against being fooled?
At present, many of these materials are not called polyurethane, but what is called polymer polymer material, and the real polymer polymer material is only referred to as JS waterproof material, and some of the manufacturers produce polyurethane in order to confuse the audio and video called GS high. The molecular material is one of the G's, and the practicality is good. The price of this kind of material 20 kg / barrel is more than 20 yuan - 100 yuan, mostly for small decoration companies.
10. How to judge whether the waterproof material is good or bad?
Judging the waterproof material mainly consider the following three aspects: (1) the coating should be free of sedimentation, delamination, agglomeration; (2) no strong pungent odor; (3) whether the construction is convenient.
