1. How to budget for waterproof material usage?
The amount of waterproof coating = waterproof construction area * per square meter of coating amount.
2. What is the amount of single square meter of various waterproof materials?
According to the usage instructions of the Shuanghong brand of various types of waterproof coatings, the brushing is 1.5mm thick, and the theoretical amount of material needed is as follows:
(1) Acrylic: Amount of about 3 kg / ?
(2) Polyurethanes: Amount of about 2.5 kg / ?
(3) Polymer polymers: Amount of about 1.5 kg / ?
(4) Flexible cement mortar: dosage about 2 kg/?
3, buy waterproof material should pay attention to what?
At present, the management of the building materials market is not standardized. There are many counterfeit products on the market, and relatively well-known brands should be selected at the time of purchase. The true environmental protection waterproof material should have ten ring certification or CTC environmental protection 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-sales, sales and after-sales services when selling products.
4. Why do you recommend building materials to buy materials?
General building materials supermarket products, clearly marked price, more regular sources of goods, it is not prone to fake and shoddy products, in addition to return disputes and other disputes is relatively easy to solve.
5, the cost of various types of waterproof material?
All kinds of waterproof coatings sold on the market, as long as they are in line with national standards, should be used as home waterproof. These coatings have their own advantages, you can choose to buy according to your needs. Polyurethane waterproof coating has good elasticity and extensibility. In terms of coating quality alone, it is the most outstanding performance 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 no-name products currently on the market are not pure polyurethane, and the environmental performance is not very good; acrylic waterproof coating, convenient construction, environmental protection, coating performance is also relatively good, and the price is moderate. Coatings; JS waterproof coating, convenient construction, environmental protection and non-toxic, is also a good choice; waterproof mortar coating, high coating strength, and grass-roots combination, can be directly paste tiles, economical and practical.
6. What are the main considerations for purchasing materials?
The first is waterproof performance, then the environmental performance. Waterproofing is a hidden project. After waterproofing, it is tiling. If toxic materials are used, it is like having poison gas bombs buried at home. And it is difficult to re-replace, so the environmental protection of materials is also an important aspect of purchasing materials.
7, how to buy environmentally friendly waterproof coating?
To regular building materials city (supermarket), choose products that have passed the China Environmental Labeling Certification and CTC Certification.
8. What is the simplest way to identify true and false waterproof coatings?
Look at the packaging, whether it meets the requirements of branded product packaging, bright colors, clear writing, according to the standard product name, net weight, place of production, certification and so on. Most of the well-known brands have their own anti-counterfeiting labels and should pay attention when buying.
9, buy polymer polymer materials to guard against being fooled?
At present, many of these materials are not called polyurethanes, and instead they are called polymer polymer materials. The real polymer polymer materials are simply referred to as JS waterproof materials. What is more, some manufacturers produce polyurethane, in order to confuse the audiovisual even known as GS polymer material, so G behalf of the other J, real 'good intentions'. The price of such materials 20 kg / barrel more than 20 yuan -100 yuan, mostly for small decoration companies choose.
10, how to judge the quality of waterproof material?
Judging waterproof material mainly considers the following three aspects:
(1) The coating should be free from sedimentation, delamination, agglomeration; (2) there is no strong pungent odor; (3) construction is convenient.
