Brush off the walls of the powder out, there are many reasons: the one hand, perhaps the foundation of the wall was not dealt with clean, inaccurate or cement grade housing structure inherent in the hollowing of a large area, and renovation construction failed to deal with; there may be leveling processing after the wall is not dry on the next step of construction, the use of electric heating and other heating equipment indoors this winter construction problems that need attention, usually the construction, an appropriate increase in room temperature, so that wall grass-roots completely dry.

Technological aspects, the powder out material. Dilution of paint before brushing, use thinner watered, if watered too much, the paint film will be thinner, not only covering the substrate could not wall, there will be out powder phenomenon. Pan Qi, said the qualified products will provide a clear watered ratio, in theory this is the most scientific. But consumers are not demanding workers in strict accordance with the proportion of watered down, construction workers own experience is worth learning, and on this basis, appropriate adjustments for different environments do. But pay attention to the span of control, if watered too much, there will be out powder, crack, and other phenomena. To identify those responsible reasons, consumers may request the re-decoration of the construction side.

Typically, wall brushing the end of 7 days to fully film. Not go beyond this time period in order to finish the work, part of the decoration the appropriate choice of primer to seal the deal with the wall substrate and improve topcoat adhesion, it can effectively prevent the emergence of late out powder.
