The waterproof coating is a general term for a material which forms a tough waterproof film on the base layer after being coated by a viscous liquid polymer synthetic material having a non-fixed shape at a normal temperature and being volatilized by a solvent or evaporated or reacted.
In fact, waterproof coatings are not as simple as everyone imagined, but also divided into many types, and naturally have different effects. Some bad businesses often shoddy in order to obtain huge profits. So today I am going to introduce you to the purchase techniques of waterproof coatings, so that you can know the secrets you don't know about waterproof coatings.
Waterproof is very important, environmental protection is more important
Waterproof coatings are used for waterproofing, but in fact, we are also very environmentally friendly! If you choose a product that is not environmentally friendly, although you can't see us after the waterproofing layer is finished, it is actually thick floor tiles or cement. Below, the harmful gases are slowly released, can the air quality in your home be good? This is the reason why many consumers are confused, why the main materials in the house have chosen environmentally friendly materials, and one of the reasons why harmful gases are still exceeding the standard .
Therefore, if you want to buy waterproof materials, you must go to a formal building materials store or supermarket, choose a well-known brand, generally good brand products are equipped with product testing reports, product certification and China Environmental Labeling certification ten ring mark or The CTC logo, these are the identity symbols of good products, so you must look carefully.
The body is not stiff and waterproof.
In fact, the stiffness of my body refers to our characteristics. Generally speaking, our physical characteristics are divided into two types: rigid and flexible. Generally, rigid refers to cement mortar, although this type has high resistance after molding. Pressure penetration, but the extension of such products is not good, a little earthquake, ground fracture or small slits, it is easy to cause water leakage, thus losing the effect of waterproofing.
The flexible waterproof layer is relatively much better. Generally speaking, the acrylic waterproof coating has better elastoplasticity and can adapt to partial deformation of the structure, so the waterproofness is better. According to the research, in fact, after the renovation of the new house, due to the structural problems of the engineering structure or the building materials itself, there will be subtle changes in the ground or the wall. Usually these extremely small changes do not affect the normal use of the house, but for the waterproof layer. It's a bit challenging, so if you choose a waterproof coating, it's best to choose a body that is not stiff.
Where to waterproof, you must know
So which piece of the family needs us to make a big difference? Simply speaking, it is the wall surface of the bathroom, the wall surface of the kitchen, and the balcony floor where the water system needs to be installed. If you live on the first floor and do a waterproof layer, the moisture-proof effect will be better.
Generally, the height of the shower and the sprinkler of the bathroom is about 1.8 meters, so the waterproofing should be done so high, otherwise it is difficult to play a waterproof role, instead of installing the shower wall, only 1.5 meters is enough. Of course, if you don't care about one or two hundred dollars, then the waterproofing here will be 1.8 meters.
How to do waterproofing of the kitchen? The key is to see which places are easy to be related to water. It is generally recommended to turn the kitchen floor and wall over 0.3 meters for waterproofing. It is best to set the waterproof layer on the wall placed in the sink. .
Performance is different, each has its own good
According to the personality characteristics of our family members, they can be divided into four types of waterproof materials, acrylic, polyurethane, polymer polymer, also referred to as JS, flexible cement mortar, but each has its own personality, such as polyurethane waterproof coating It has good elasticity and extensibility. If it is from the effect of forming a waterproof membrane, it is the most comprehensive performance of various types of coatings, but it also has its own shortcomings, that is, it is subject to time limitation and long construction time. And the price is more expensive.
It is worth noting that due to the good performance of the products, there are already many counterfeit products on the market with polyurethane signs. Most of them are not pure polyurethanes. The environmental performance is not very good, but the price has dropped, so it must be selected. Pay attention to; acrylic waterproof coating, convenient construction, environmental protection, film performance is also good, the price is moderate, the general home decoration waterproof will use this kind of paint; and JS is a rigid and soft waterproof coating, easy to construct, environmentally friendly and non-toxic, also At present, the waterproofing mortar coatings are widely recognized and recommended for use in waterproofing. The waterproof mortar coatings have high strength when combined with waterproofing membranes. At the same time, they are well bonded to the base layer. After construction, the tiles can be directly pasted, which saves construction time. The price is also relatively more economical and practical, but its shortcoming is that it is a rigid waterproof material and is not suitable for new home decoration where there may be settlement.
How much is calculated by the material?
Many consumers will feel headaches when they buy us. How much should we buy? In fact, we also have certain calculation formulas. If you master this rule, you will definitely buy it just right. According to the construction height of the bathroom introduced for you, the waterproof area of ​​the bathroom (square meter) = (the perimeter of the bathroom floor - the width of the door) × 1.8 meters (height) + (the floor area), of course, this refers to the wall The waterproof surface is made to a height of 1.8 meters. If you want to make 1.5 meters, you can change the height; the waterproof area of ​​the kitchen (square meter) = (the width of the kitchen floor - the width of the door) × 0.3 meters (high ) + (ground area) + the width of the wall of the sink × 1.5 meters.
Although I know the area, in general, when buying waterproof coatings, they are calculated by weight. How to convert them? Don’t worry, this formula also has acrylic, which is 3 kg per square meter; The amount of rice is about 2 kg; the polymer polymer is about 3 kg per square meter; the flexible cement mortar is about 3 kg per square meter.
