The paint must be protected from rain and dust contamination when it is applied and before it is dried. Note that it is not advisable to work under a wall surface temperature of less than 10 degrees Celsius. In the second decoration, before the latex paint is applied, the original paint layer must be removed. Then use the fly powder and cooked rubber powder to mix the bottom. Then paint latex paint. The surface layer needs to be painted 2 to 3 times. It must be reminded that many industrial paints have more or less toxicity. Attention should be paid to ventilation during construction. After construction, they must be volatilized at least for more than one week before they can be accommodated. In order to avoid harm to the health of the family. In the purchase of latex paint, in general, the words used for the production site and the manufacturer's name marked on the paint bucket are one of the traditional Chinese characters, and the other one is in uppercase English. The former is slightly inferior to the latter in quality. Although this appraisal method is "earth", it is still useful.

In terms of construction, the putty on the wall should be prepared from special white old powder, white cement, water, chemical paste, and 801 construction glue. In the preparation, the white cement is first opened with a small amount of water, and then an appropriate amount of 801 glue, chemical paste, and old powder are sequentially added, and the mixture is stirred until the appropriate concentration is reached. One of the quality requirements is to be flat, and the other is light, and there should be no pores. The test method can use a light bulb to observe from the four corners of the wall and whether the brush is smooth or not, at a glance. After the putty is approved, it shall be completely dry, painted with a seal primer matching the optional latex paint, and then be painted with a top coat. Both the primer and the top coat can be adjusted slightly thin to avoid leaving traces of paint. Every time the paint is to be dried, it can be painted a second time. In addition, if there is a paint construction at the same time, after the old powder is approved, the paint should be completely finished, and then the latex paint should be applied so as to prevent the paint from evaporating out of the paint and causing unnecessary losses.
