The classification knowledge of several coatings commonly used in exterior walls is popularized

Exterior wall coatings, basically divided into latex paint, elastic paint, texture paint, real stone paint, colorful paint, metal paint (currently used less); Others, there are some special processes, such as the effect of clear concrete, such as the board directly glued to the finished product of the imitation sandstone effect.

1. Exterior wall latex paint:

1) Price, from 30 to more than 100 have.

2) Only cleaning effect, good latex paint can still be as new after a few years. No elasticity, no anti-cracking effect.

3) Can only be used in Guangdong, Hong Kong and other areas without external insulation. It is more commonly used for the renewal of old buildings (the settlement of old buildings has been completed).

2. Elastic coating:

1) Used in areas with external insulation, because external insulation is plate splicing, it will cause dislocation with the settlement of the building, resulting in dislocation tension of the external wall coating, which will make the paint crack. Therefore, it is necessary to make the exterior wall coating elastic anti-cracking function (resin).

2) The price ranges from dozens to hundreds of pieces, and the main difference is in the different quality of the resin used. The price of the conventional elastic paint is a few dollars, and this is a little more.

3) Elastic coatings are divided into two kinds: a single layer and a multi-layer. When originally originated in Japan, there was only a multi-layer elastic coating, that is, the sandwich that plays an elastic anti-cracking function and the surface layer that plays a cleaning function are separated, which is more expensive, so after entering the Chinese market, a single layer of elastic coating was developed, that is, the two functions were integrated into the surface layer. The cleaning function and anti-cracking function of the elastic coating are actually a contradiction, and different brands will have different focuses (materials with good elasticity, such as certain viscosity, will inevitably have the performance of absorbing pollutants, and its plot performance will inevitably decline).

4) According to the project shape and construction technology, it can be divided into flat, small latte, large latte or relief modeling, but its texture is bound to be monotonous than the texture paint.

5) As shown in the figure, it is a relief modeling, which adds a special relief modeling layer under the surface layer.

6) The elastic coating falls off, often due to quality problems such as putty and air base, or because of water seepage.

3. Metallic paint:

1) Mainly imitation aluminum plate effect.

2) No elastic effect, so it is not suitable for areas with external insulation.

3) If you need to add an elastic layer, it can prevent cracking, but it lacks a metallic feeling.

4. Real stone paint:

1) The material of real stone paint is mainly made of natural stone crushed particles, real stone paint is generally divided into single color or colorful (also called multi-color, different from multi-colored stone), the price of real stone paint is basically more than 100, and the domestic brand is about 70 yuan.

5. Multi-colored stone (colorful paint) :

1) Multi-colored stone paint and real stone paint is still different, at present, only a few foreign brands can do multi-colored stone, domestic generally can not do.

2) Its raw materials and real stone paint is different, does not contain stone particles, is made of resin. Multicolor is made of resin or emulsion. When it is liquid, it has a similar effect to bubble tea. After spraying, it has small dots of other colors, similar to the effect of granite.

3) Construction process: It is basically a one-time construction, which is different from real stone paint and requires multiple and multi-layer spraying.

4) Compared with real stone paint, its effect lacks convex texture.

5) The price is not necessarily low, basically about 100 yuan, see different manufacturers, more than 100. Imitation stone depends on what kind of imitation stone, and the price of real stone paint and colorful paint on the market is almost the same. Individual stone, sometimes the real stone paint is expensive and sometimes the colorful class is expensive, the past two years have used a lot, because relative to the real stone paint, some stone, this product can be more like some imitation.

6) Multicolored stone:

6. Texture coating:

1) Texture paint is made of quartz sand... It's just kind of like a little sand.

2) The advantage of texture paint is that it can make more different textures, more rich.

3) The disadvantage is that the texture paint is basically monochrome (it can also be combined to do multi-color), so it is often more suitable for Spanish rural style and Southern California style.

4) Price: To see what shape, generally the simplest shape, basically 60 pieces, some will go to more than 100.

5) The difference between elastic paint and texture paint: elastic paint can only make a small amount of texture effect, and other can not be done.
