Recently, many owners who are engaged in home decoration have consulted Chenyang Water Paint customer service whether they must apply primer when choosing wall paint.
Highlights: The use of primer is crucial during the renovation process, and this is especially critical for homeowners who live in southern or coastal areas!! Let's talk about this problem in detail.
[1] Is it okay to paint the topcoat without primer?
It is not possible to brush the top coat without the primer.
The role of primer and topcoat in wall decoration is complementary, and the main role of primer is to close the wall, enhance adhesion and improve hiding power. Applying primer can save the amount of topcoat, and the amount of topcoat used on the wall without primer is about 20% more than that of the wall with primer.
The main role of the topcoat is to decorate and protect the base layer. The primer provides a good base for the topcoat, which further enhances the decorative effect and protective properties of the coating.
Therefore, in order to achieve the best coating effect on the wall, it is recommended to follow the construction process of priming first and then painting.
[2] Why do many masters say that they don't need to paint primer?
Chenyang Water Paint Answer: This is mostly related to the local climate problem. If you don't paint primer, it may come from Shaanxi, Beijing, etc., where the climate is dry all year round, and there is no need to worry about the problem of anti-alkali on the wall. However, in the south or coastal areas, the primer must be brushed, otherwise the problems of mildew and alkali return will be very serious.
[3] wall construction process steps:
(1) After the putty is dry and sanded, the ash is removed and the primer is brushed once.
(2) The topcoat is 2 to 3 times, and each process should be brushed after the paint of the previous process is dry.
(3) During the primer construction, the wall absorbs a large amount of paint, and a little more water can be added when the primer is diluted to ensure that the coating is uniform.
(4) The topcoat should be mixed with water in proportion, and do not add too much water, otherwise it will affect the thickness of the paint film, feel and hiding power.
In order to make your wall show a better decorative effect, Chenyang Water Paint hereby reminds you that you must not ignore the key step of primer, which is very important to improve the quality of your wall!
