The wall paint not only plays a role in protecting and decorating the wall, it is also developing towards the trend of rich color, environmental protection and development. It can be said that people in this era are becoming more and more picky, and the requirements are also increasing. In the process of home decoration, the decoration is required to achieve good results, and the walls decorated with paint should bring beautiful effects., It also requires energy conservation and environmental protection. The important thing is that it is non-toxic and harmless, and does not harm people's health. So this in the choice of paint but to add some difficulty, because the market a wide variety of coatings, it is difficult to take into account their own multiple requirements. So wall paint in the end have those? The next article in the small and medium-sized will give you a detailed introduction.
What are the 1. wall coatings?
(I) interior wall paint
The main function of the interior wall paint is to decorate and protect the interior wall (including the ceiling), make it beautiful and clean, and let people live in a pleasant living environment.
Interior wall coatings use environmental conditions are better than exterior wall coatings, so in terms of weather resistance, water resistance, stain resistance and coating temperature resistance, etc., the requirements are lower than exterior wall coatings. In terms of performance, exterior wall coatings can be used for interior walls, while interior wall coatings cannot be used for exterior walls. However, interior wall coatings are often higher than exterior wall coatings in terms of environmental protection.
1. Water-soluble coatings
Water-soluble interior wall coatings are made by using water-soluble polymers as the base material, adding a certain amount of pigments, fillers, additives and water, and grinding and dispersing them. For example, polyvinyl alcohol water glass interior wall coatings, polyvinyl alcohol methanol interior wall coatings and imitation porcelain interior wall coatings are all water-soluble interior wall coatings.
2. Resin emulsion coating
Also known as interior wall latex paint, it is made of resin emulsion with pigments, fillers, additives and water. The main feature of the interior wall latex paint is water as the dispersion medium, so it is safe and non-toxic, does not pollute the environment, and is an environment-friendly paint.
(II) exterior wall coating
Exterior wall coatings are coatings applied to the exterior of buildings or buildings. After the film is formed, the coating film is exposed to the external environment for a long time, and it must be subjected to sun and rain, freezing and thawing alternation, dry and wet changes, harmful substances erosion and air pollution, etc., to maintain lasting protection and decorative effects, that is to say, there is a For a relatively long service life, exterior wall coatings must have certain performance. National and industry standards for exterior wall coatings are as follows:
1. Inorganic coating for exterior wall
Inorganic architectural coatings for exterior walls are based on alkali silicates and silica sol as the main binders.
2. Building coatings
Multi-layer architectural coatings are composed of multi-layer coating films, such as primer, primary coating and top coating. Multi-layer architectural coatings can be divided into four categories according to different binders used in the main coating, namely, polymer cement, silicate, resin emulsion and reaction curing resin emulsion.
3. Sand wall architectural coating
Sand wall exterior wall coatings are a class of coatings with a coating finish as coarse as a sand wall. It is made from the base material, different colors, different particle size of gravel, pigments, fillers or slices, etc., and is mostly used for the exterior wall coating of buildings. It is characterized by strong three-dimensional sense, can be constructed into imitation granite and imitation brick and other various, good decorative effect, giving people a classical and elegant feeling, thick coating, good weather resistance, but poor stain resistance.
4. Inorganic coating for exterior wall
The exterior wall inorganic architectural coating is an exterior wall architectural coating that uses alkali metal silicate and silica sol as the main binder and uses brushing, spraying or rolling to form a thin decorative coating on the building.
5. Hot-melt fluorine resin coating
6. Crosslinked fluorocarbon resin material
7. Texture coating
Texture paint is mainly the use of special tools on the wall to create different shapes and patterns, so that your space is more three-dimensional and true and beautiful. Texture coatings are mainly elastic texture coatings, dry powder texture, wet slurry texture, etc., different series, to achieve the effect is not the same.
Texture paint with its infinitely changing three-dimensional texture, multi-choice personality collocation, show a unique spatial perspective, rich and vivid, refreshing. And to create a personality to meet the overall decorative style, making the texture paint in the decoration to show their own unique style! Texture paint can also be called art paint.
Construction Technology of 2. Interior Wall Coating
The following is an example of latex paint to introduce the construction process of interior wall paint:
1. Now the concrete is evenly sprayed with glue, and the ratio of water to emulsion is 5:1;
2, in the construction surface scraping putty twice, the first time horizontal scraping, the second time vertical scraping, each putty after drying application sandpaper grinding and dust removal;
3, the following began to brush the first time paint, first up and then down, after the paint dries to fill putty, putty after drying with sandpaper polish, brush the second time paint the next day;
4. It is not advisable to brush the paint back and forth for many times when brushing the paint for the second time, which will loosen the paint film for the first time or leave traces of coating, seriously affecting the appearance and quality;
5, the third coating construction to ensure the uniformity of the coating color, pay attention to the coating hiding power, at any time to grasp and adjust the tightness of the coating. After the completion of the work, the wall shall be properly protected and shall not be bumped or polluted.
