Renovation specification brushing wall attention process

Wall projects often run through the entire process of construction. If there are wooden walls or shapes, they will be entered in the early stages of construction. If only the paint is applied, it will start work in the middle and later stages. However, for the construction of the wall, the paint painting is often done through scraping, sanding, brushing, primer, and other procedures. If it is not done in strict accordance with the construction specifications, if the brushing is not in place, or if it does not wait until the previous one. If the process is dry enough to proceed to the next process, wall cracks, cracks, etc. will easily occur.

Brush wall lining should be strictly controlled. It is necessary to scrape the wall lining before brushing the wall paint. Generally, it needs to be scraped 3 times. The normal dry time is 1-2 days. Since spring is a rainy season, the selected wall ash must be waterproof, moisture-proof, anti-powdering, and mildew-proof.

The role of the primer is to close the wall and resist the alkali material that the cement layer of the wall seeps out. The primer can also increase the hardness of the gray layer of the wall, and can also improve the adhesion of the topcoat because of the primer to the wall. The body is closed, preventing the wall from absorbing the top coat. The top coat stays on the surface, thus increasing the fullness of the finish.

Only in the extremely low-demand project renovation (such as whitewashing of walls or underground works), the use of primer is not considered due to price and use environment. The effect of home decoration is required by advanced decoration and the service life is relatively long. The cost can also be affordable, it is recommended to use a primer.
