It is often heard that some people complain that the walls of the home have been chalked, faded, and peeled for a long time. How can these phenomena be solved? Do not worry, here we take a look at the solution!
Powdering problem:
First of all, it is necessary to thoroughly deal with the wall surface, use old powder and other materials (preferably use special wall putty) to paint the wall surface and polish it. Keep in mind that no matter what grade of latex knee is used, the quality standards for handling walls cannot be reduced. Second, first coat it with a water-based or oily back cover primer, and then coat it twice. (Some brands of latex paint have been specially treated, but no primer is required). Third, it must be mixed with water according to the prescribed ratio, and construction at low temperatures must be avoided.
Discoloration and fading problems:
Some wall temperatures are too high (long sunshine hours), water-soluble salts crystallize on the surface of the wall (weathering) resulting in discoloration and discoloration; some walls contain too high basic values, infringe the anti-alkaline pigments or Resins cause discoloration and discoloration; some are improperly constructed and applied at the same time as polyurethane paints. The TD1 components contained in these paints will discolor the latex paint. Solution: The first case is relatively rare and can be consulted with the person concerned; for the second case, the above-mentioned treatment method for the wall body can be used; in the third case, the paint can be recoated after two days (25°C). Latex paint, or until the latex paint is completely dry (25°C temperature), paint after 7 days.
Peeling and peeling problems:
Observe before construction, if any leakage occurs, please promptly ask the relevant department to solve it; if the house is newly built, then the phenomenon of evaporating water from the wall is inevitable. It is recommended to use a durable and waterproof elastic putty. Walls are pretreated and then treated as usual.
