♀? Evaluate the wall surface

Evaluate the wall, accurately measure the room area, wall humidity and other wall conditions, and choose colors and products according to the decoration style of the home. Before construction, we should protect furniture, household appliances and other objects and handle every detail.

Clean the wall

Cleaning the wall: clean the loose putty layer on the wall with a shovel. The putty layer that cannot be removed with a shovel can be tapped with a small hammer. If there is no empty drum sound, the original base can be retained where it is still not loose after knocking.

Clean the wall

Cleaning the wall: clean the floating dust and oil stains on the surface. Use water-resistant putty to completely repair the local damaged part and level the wall surface.

Polishing: Try to use fine sandpaper. Generally, 400-500# sandpaper is used for soft putty (such as 82 1), and 360-400# sandpaper is better for hard putty (such as wall lining and easy gunning). If the sandpaper is too thick, it will leave a deep sand mark and cannot be covered with paint. The polished wall must be thoroughly cleaned to avoid too much dust and affect the adhesion of paint. Uneven difference is less than 3 mm

primer

Primer: Primer must be brushed evenly to ensure that the wall is brushed everywhere. If the wall eats a lot of paint, it is best to add a little more water to the primer to ensure uniform painting. Don't think it's just a primer, just use a similar roller. The brushing effect of primer will directly affect the effect of topcoat. Use a roller with the same texture as the top coat.

Top coat: The paintings here are suitable for ordinary paintings. Do not add too much water, which will affect the thickness, feel and hardness of the paint film. Try to choose better tools. The hair of the roller should not be too short, but it must be thin, so that the paint film drawn will have a delicate feeling. Pay attention to the corners, indirect stubble and paint collection direction of each roll.

Pay attention to your health

Maintenance: latex paint will dry after 4 hours, but the dried paint film has not reached a certain hardness, so be careful. It's simple. 7- 10 days, just don't paint the wall or touch it.
