In the home renovation to buy wall paint, we will find in the building materials store will now be divided into a lot of wall paint primer and topcoat, primer used in contact with the wall layer, the top layer of surface paint, You may know this kind of simple distinction, but the difference between the price of primer and topcoat is not small. What is the difference between the two? What is the primer? The primer is a liquid that is usually white in color and has a certain viscosity. It can be directly applied to the surface of the object. It is the first layer of the paint system and is used to improve the adhesion of the top coat and increase the fullness of the top coat. Improve the finish of the paint, provide anti-alkaline, provide anti-corrosion function, etc. At the same time, it can ensure the uniform absorption of the top coat and make the paint system exert the best effect. Generally, it can be divided into the first coat primer and the second coat base according to the coating requirements. Paint and so on. The role of primer 1. Closed Primer can effectively seal the base layer, so that the wall base is more solid. Some of the walls are more basic and produce alkali after soaking with moisture and water. The scientific name is “alkaline.†This condition causes craters to form on the surface of the paint film. In severe cases, a layer of alkali cream forms on the surface of the paint film. Ultimately the paint film is destroyed. Latex primers can act as a seal to ease this situation. However, if your house wall is relatively dry and the floors are high, it is not possible and there will be no problem, but it is recommended that you use it, so it is more insurance. 2, adhesion The primer can enhance the adhesion of the topcoat and improve the adhesion of the latex paint film to the wall to avoid peeling off of the wall. 3, fill in The primer can make up for minor cracks and improve the flatness of the wall. If your wall is flat, you can use no primer. Of course, the effect will be better. 4, cost savings The price of the primer is generally cheaper than the top coat, so applying the primer before applying the top coat can save the decoration cost. Wood paint primer and paint difference 1. Composition From the point of view of the composition of the paint, the wood paint primer is mainly composed of: film-forming substances, fillers, solvents, auxiliaries, etc.; wood paint finishes are mainly composed of: film-forming substances, solvents, auxiliaries and the like. The composition of the two is different 2, the effect of the effect From the perspective of the effect and effect, the primary role of the primer is to fill the pores, increase the thickness of the coating, and make the objects achieve a certain decorative effect, thereby reducing the amount of topcoats, generally have a certain degree of filling, grinding, hiding power, etc. The topcoat is mainly used for decorative and protective purposes, with a certain degree of gloss, color retention, hardness, adhesion, leveling and other effects. From this point of view, the roles of the two are different. 3, price From the price point of view, the price of the primer is lower than that of the topcoat. In general, the price of the primer under the same conditions is about two-thirds of that of the topcoat. The use of a primer in the decoration can reduce the amount of topcoat used. As a result, decoration costs can be saved. The use of primers and topcoats Primers and topcoats are all latex paints, and they usually need to be used together. When painting a wall, the primer is usually applied after the putty is completely dry. Usually, the primer needs to be brushed twice. Since the wall has a relatively large amount of paint, the primer is adjusted. When you need to add some water in a modest amount, you can ensure that the primer is applied evenly. The topcoat usually needs to be painted three times on the wall when it is applied, and it cannot add as much water as the primer. Adding too much water will affect the feel, thickness, and hardness of the paint film. Therefore, only a small amount of water may be added at the last time when the paint is applied. Summary: The above is the difference between the wood lacquer primer and topcoat that Xiaobian introduced for everyone. I hope you can help us effectively.
