Does latex paint need primer?

Common misunderstandings in brushing latex paint?

1, the finished wall looks as smooth as possible.

For the sprayed wall, the smoother the surface, the better, but not for roller coating. The wall looks smooth after roller coating, which is actually caused by more water in the coating. However, if too much water is added, the paint will easily fall off, and the surface paint film will be thin, which will not protect the wall well, and will also reduce the elasticity of the paint and make it difficult to cover the tiny cracks in the putty layer.

There is white powder in hand, which indicates that the paint has quality problems.

In the process of construction, there will be a lot of dust attached to the wall, and there will be a similar phenomenon of powder falling after touching it by hand. At this time, you can wipe off the dust with a duster and solve it. Therefore, when purchasing latex paint, you should ask the merchants about the grade of latex paint. The lower the grade, the worse the wear resistance of paint, and the easier it is to lose powder.

3, latex paint roller can't roll without water.

Because the dark paint has poor concealment, it is easy to paint the wall if you add water when you roll, so don't add water when you paint. For the same area of wall surface, the amount of dark paint used for roller coating is at least twice as much as that of light paint.

4. Primer is of little use and can be used without it.

As long as the wall is painted with putty, it is necessary to brush the primer, because putty is water-resistant and alkali-resistant, and the primer has the effect of alkali resistance. If you don't brush the primer, the putty will return to alkali and the wall will turn into flowers.

5. The more expensive latex paint is, the better the effect will be.

After the construction of latex paint, the wall effect is good. The higher the coating grade, the higher the content of latex raw materials and the higher the construction technology requirements. If you don't pay attention to the construction, it is easy to paint the wall. Therefore, before construction, construction personnel should strictly follow the construction requirements in the product description.
