I don't care if I can do wall paint directly, but I should make an anti-alkali primer because the epoxy cement will destroy the wall paint film immediately after the alkali is reversed, to be precise, the vast majority of moisturizing emulsions are all acrylic.

raw material, touching the partial alkali in the epoxy cement destroys the molecular formula. However, in the middle and later stages, if the putty is batched, a layer of waterproof putty must be made first.

Wall Treatment Process:

Step 1 Check.

Situation 1: Cement wall. Comprehensively check whether the cement wall that needs to be painted in the blank room is solid and smooth.

If the plastering layer on the wall is not strong enough or there are large cracks and holes, it is advisable to complain to the developer or the property and ask it to be redone. Individual holes can be filled with plaster if repaired by yourself. If the flatness of the wall is poor (the error is greater than plus or minus 5mm), then it should be considered to do plaster leveling first.

Situation 2: Putty wall. Be sure to check whether the wall putty is qualified water-resistant putty, if not, you must shovel off and redo the water-resistant putty. Other projects are the same as in case 1.

The process of brushing latex paint:

1.First use water to mix latex paint, the proportion of water added to the roller coating is generally controlled to 20% to 30% according to the volume ratio is the appropriate ratio, if there is too much water, it is easy to cause poor film formation of latex paint.

2.Stir the paint and water evenly and then stand for 20 minutes to achieve the purpose of defoaming, so as to avoid needle holes or small bubbles after the latex trace shed is painted on the wall.

3.Still time passes. It's time to paint. Then moisten your tools with water, such as the wool brush and roller at the corner of the shade, first moisten with water, and then dip the material. The next step is painting.

4.Latex paint is painted according to the standard process, which is applied in a bottom-to-bottom and two-sided way.

1) first brush the primer to close the alkalinity and increase the mechanical bite (adhesion) of the bottom coat, the painting process is the living room and then the bedroom, the top plate (ceiling board) and then the wall.

2) If you feel that the wall is not delicate enough, you can also gently remove some small particles on the wall with water sand before brushing the second topcoat.

3) After each painting, the interval is 2 to 4 hours before painting, or you can feel it with your own empty fingers, if the paint surface pressed with your fingers does not feel sticky (acupressure dry), then it means that you can paint.

4) The position of the switch box and door cover and window cover should be covered with masking paper before painting. Masking paper can be bought together with a roller and a wool brush.

The wall surface of the blank room before direct painting is treated, so that it can be more convenient when painting, and the treatment effect of painting will be better. There is a lot of knowledge about wall painting, and when you want to paint the wall when you do decoration, you should find a good decoration master to complete it for you.

OK. If you don't care about the flatness, you can directly do latex paint, but you need to do a layer of alkali-resistant primer, because the cement-based anti-alkali directly destroys the latex paint film, to be precise, most of the emulsion is acrylic raw materials, and the alkalinity in the cement-based destroys the molecular structure.

However, in the later stage, if the putty is scraped, a layer of interface agent needs to be made first. The unevenness of the cement blank wall itself has little effect on the adhesion of the greasy grip in the later stage. If you consider that you still plan to decorate in the later stage, then it is recommended to scrape the water-resistant putty and leave it blank.

Because after the water-resistant putty is primed, there is no need to scrape the putty again in the later stage of the wall material.
