Due to the corrosive effects of various natural elements, the paint is greatly affected by the natural environment. Therefore, before the construction of the project, how to choose the coating is an important step. In the face of more than 100 types of coatings currently on the market, attention should be paid to the following points when choosing.
1, according to the different data of the building structure selection. The different materials and materials of the building structure have different requirements for coatings. The concrete and cement mortar base layer should be preferentially selected for the polymer-based water-based paint; the lime-water base layer is preferred to use the polyvinyl alcohol-based water-based paint; the wood base layer and the metal base layer are preferentially selected. Solvent coating.
2, according to the different parts of the building selection. Different parts of a building have different requests for their exterior decoration and maintenance. For example, interior wall paints used in interior walls are close to people, they are clearly seen and touched, so they require strong adhesion and fine texture. Resistance to differentiation, good air permeability; kitchen, bathroom, toilet paint should have waterproof, mildew, easy to scrub performance.
3, according to the distance between the time of the decoration of the building and the next decoration. If the distance from the decoration of the building to the next decoration is long, the durable paint should be used; if the distance is short, the paint with poor durability can be used.
