Paint is an indispensable material in decoration. I believe we all know that there are many types of paint, such as wall paint, primer, exterior paint, and top paint, but different types of paint have different uses. The following Xiao Bian will introduce to you the difference between the primer and the topcoat, and the difference between them is clearer.
1, the primer
Primer is a coating that is applied directly to the surface of a surface as a solid foundation for a topcoat. This material requires a firm adhesion on the surface of the material, while it increases the adhesion of the upper coating, and the use of it is to improve the decorative properties of the topcoat. According to the coating requirements in general can be divided into the first primer, second primer and so on.
2, topcoat
This is also called finish paint and is the last coat of paint in a multi-layer coating. This product has a good resistance to external conditions, but also must have the necessary hue and decorative, and protective effect of the primer. If you are using a topcoat for outdoor use, then it is recommended that you use a paint with good weatherability. 3, different composition
Primer is used as the auxiliary paint for topcoats. Among them, transparent paint and solid primer are composed of film-forming substances, fillers, solvents, and auxiliaries; while the transparent colored topcoats in topcoats are made of transparent topcoats and Color fine composition. The difference in composition between the primer and the topcoat is also due to its own characteristics, properties and uses. The topcoat has a strong decorative effect and anti-aging effect. At the same time, the primer has a relatively strong adhesion and texture.
3, different performance
Primers and topcoats are also very different in terms of performance. Primers are generally divided into sealers and primers. Sealers are used mainly as a substrate for closures, to protect sheets and to ensure coating quality. Primer It is mainly used to fill pores, increase coating thickness, reduce the amount of topcoat, etc.; the function of the topcoat also plays a role of decoration and protection, must be gloss, color retention, hardness, adhesion, leveling, etc. .
4, the price is different
The price of paint and topcoat on the market is also different because of its own use and composition, but the price is also high or low. Those who attach importance to the quality of the decoration will choose a good primer, such as the emphasis on decorative effects, then they will choose a better finish.
5, from the concept of
The difference between wall primer and topcoat is that one is applied directly to the wall and one is painted on the surface. Primers and topcoats exist at the same time, but primers and topcoats are complementary, and they also have their own roles. The color of the topcoat needs to be backed by a primer, while the topcoat is a primer that supports the face.
Summary: What is the difference between the primer and the topcoat? The difference between the two is clearer than the difference between the primer and the topcoat. The primer and the topcoat have their own functions. The two are complementary alternatives. I believe that the above is introduced so that they have a certain understanding.
