Can the Walls be Painted Directly?
As a Custom Soft Pattern Roller Exporter, share it with you.
The cement wall cannot be painted directly, because the construction wall is 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, and the cement is alkaline, so directly apply the wall paint. Waiting for a long time is easy to take lye.

Cement wall painting method
Hand brushing, rolling and spraying can be used as the construction method when painting, and the technique should be continuous and rapid when painting. 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.
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.
