Can the cement floor be directly carpeted? Can the cement wall be directly painted with latex paint or paint?

& gt First, cement walls cannot be directly painted.

First of all, Bian Xiao clearly tells you that the cement wall can't be brushed directly, because the construction wall is flat and easy to contain dirt such as floating ash. Direct painting will not only pit the wall, but also easily lead to falling off. Moreover, cement contains alkalinity, and it is easy to take alkali flowers when it is directly brushed on the wall.

Second, the cement wall painting-cement wall painting steps

First, clean up the grass-roots level → fill putty, locally blow putty, smooth it → scrape putty for the first time, smooth it → scrape putty for the second time, smooth it → brush closed primer → brush paint for the first time → repair putty, smooth it → brush paint for the second time → polish it.

Third, paint the cement wall-paint the cement wall to ensure the quality.

The key link of construction quality is absolutely grass-roots treatment, and the basic guarantee condition is that the wall must be completely dry, usually for ten days; At least two layers of putty should be scraped on the wall to ensure the smoothness of the wall. Putty should match the performance of paint. Water-resistant putty should be used in wet places such as toilets, and special putty should be used for interior and exterior walls. After putty, the exterior wall needs alkali-resistant primer, and the interior wall can be directly coated without alkali-resistant primer.

Four, cement wall painting-cement wall painting method

When painting, the construction method can be hand brushing, roller coating and spraying. When painting, the method should be continuous and rapid, and painting should be completed at one time. Bian Xiao thinks that the material loss of hand brush is relatively small, and the quality can be guaranteed. However, the construction period is long, so it can be combined with roller coating, which is used for large areas and hand brushing for corners. This can not only improve efficiency but also ensure quality, which is very practical.

The coating liquid must be fully stirred evenly. If the viscosity is too high, water can be added appropriately, and if the viscosity is low, thickener can be added appropriately. Pay attention to the wall painting construction to ensure that the temperature is higher than 10 degrees Celsius, there can be no large amount of dust indoors, and it is best to avoid rainy days.

Well, that's Bian Xiao's introduction to the process of painting the wall. I hope that friends who are decorating or planning to decorate will read it carefully or collect this article. Don't brush the cement wall directly to avoid greater losses. Another thing to remind friends is that the edges and corners should be painted evenly and carefully to avoid missing painting. When painting in a high place such as a shed, you must pay attention to safety, choose a ladder with a suitable height, avoid dangerous actions such as tiptoeing, and let relatives or friends hold the ladder below if necessary. In short, remember that safety comes first!
