How to Paint the Cement Wall?

As a Custom Painting Rubber Roller Exporter, let me share with you.

1.The editor clearly tells you that cement walls cannot be painted directly, because the construction walls are flat and easy to contain dust and other dirt. Direct painting will not only cause pits on the wall, but also easily lead to peeling. In addition, the cement contains alkaline, so it is easy to take alkali bloom after waiting for a long time.

2. The steps of painting cement walls

First, clean the base layer → fill the putty, scrape the putty locally, smooth → the first pass full scraping putty, smooth → the second pass full scraping putty, smooth → apply the sealing primer → apply the first coating → refill Putty, smoothing → brushing the second coating → polishing and working.

3.Paint the cement wall to ensure the quality

The key link of the construction quality is definitely the grassroots treatment. The basic guarantee condition is that the wall must be completely dry, usually for more than ten days; the wall needs to be scraped with at least two layers of putty to ensure the smoothness of the wall. The putty should follow The performance of the coating is matched. Water-resistant putty should be used in wet places such as toilets, and special putty should be used for internal and external walls. After putty, the external wall needs to use alkali-resistant primer, and the interior wall can be directly coated without alkali-resistant primer.

4. The method of painting cement walls

Hand brushing, roller coating and spraying can be used as the construction method when painting. The technique should be continuous and rapid, and the brush should be finished at one time. The editor feels that the loss of materials by hand brush is relatively less, and the quality can be guaranteed, but the construction period is longer, so it can be combined with roller coating, using roller coating for large areas, and hand brushing for corners. In this way, it can improve efficiency and ensure quality, which is very practical.

5. Precautions for painting cement walls

The coating solution must be fully stirred and evenly mixed. If the viscosity is too high, add water appropriately, and if the viscosity is small, add a thickener appropriately. Pay attention to the wall painting construction to ensure that the temperature is higher than ten degrees celsius. There should be no large amounts of dust indoors, and it is best to avoid Open rainy days.

Well, the above is the introduction of the editor on the wall painting process. I hope that friends who are decorating or planning to decorate will read it carefully, or collect this article. Don't paint directly on the cement wall, so as not to lose money. Also, I want to remind friends that the corners and corners should be applied evenly and carefully to avoid omission. When brushing in higher places such as sheds, you must pay attention to safety. Choose a ladder of appropriate height and avoid dangerous actions such as tiptoeing. At this time, a relative or friend can hold the ladder below. In short, remember that safety comes first. Our company also has 6 "Pattern Roller on sale, welcome to contact us.
