Autumn is the construction season, update the construction points of wall paint.

Autumn high-spirited, is the golden season of decoration and construction, the following small editor and we discuss the next autumn paint construction precautions. Renovation friends pay attention, now start to draw the focus!
1, test wall moisture content
wall moisture content can be tested with water content tester; Water content is too high in the case to do a good job of ventilation and drying, this is also the biggest benefit of autumn construction, autumn high air cool, dry fast, full, it is not easy to return to

.
II, test wall alkaline
pH value can be tested with pH test paper - first with distilled water to wet the test paper, attached to the substation to be tested, according to the degree of color change can be known the alkalinity of the wall. PH value to neutral as good, the common problem is too high alkaline, alkaline too high will lead to wall flowering and other problems. Serious need to first use lysate to meal, not very serious cases can be remedied by brushing primers.
Three, putty, paint ratio ratio to be accurate
ratio is not allowed to affect the wall toughness and strain, if the dilution ratio of wall paint is too high, excessive dilution, will destroy the molecular structure of wall paint, resulting in paint film strain is not enough, easy to produce cracks.
the wall putty can not scrape too thick, because the indoor air is dry, water loss is faster, it is easy to cause empty drums, cracking, wall inequality. In addition, the wall scraper putty can not rely on the temperature drying, but to rely on the wind natural blow drying, so putty must not be too thick, can be blown several times. The putty on the wall is dry enough not to crack, reducing the hassle of repeated repairs in the future.
I, wall polishing
the purpose is mainly for the flatness of the putty layer, so that after painting before flat good-looking, if the east bump west bump, when the light shines, the whole wall is very ugly. It also makes the surface of the putty layer delicate and uniform, and improves the adhesion and performance effect of the paint. It is generally recommended to polish the walls at night, with 200 watts of high lamps, so that where not polished well, you can see at a glance. Autumn air dry, after the putty, generally 3-5 days can enter the grinding process. Note that there will be dust in the polishing, and construction personnel should wear masks.
5, paste grid cloth
the owners who are about to decorate also pay attention to see if there is a grid cloth on the wall of their home, not necessarily in the decoration time to be re-affixed. The role of the mesh cloth has two, the first is to prevent the wall from cracking later, and the second is to make the re-scratched putty or gypsum can be firmly bonded to the original wall.
, primer wall paint must be brushed
primer is usually used to seal the wall substrate, enhance adhesion, play an anti-alkali, rust-proof and other role. The use of primer can usually improve the overall effect of the paint, save the amount of finish and shorten the construction time. Direct construction without primer will affect the surface and texture of the paint film, and may also cause problems such as powdering. Metal coating without primer can not obtain effective anti-rust effect. For wall paint, primers are usually brushed once.
Pay attention to the primer will be marked primer, and paint is completely different, some companies because of cost considerations, will fool consumers with cheap primer to do primer, primer and finisher efficacy have a division of labor, can not be confused with the use.
primer completely dry paint film molding (generally 1-3 days, low temperature, humidity conference correspondingly extended drying time, autumn temperature and air humidity are conducive to drying and paint film rapid molding, which is one of the main reasons for the construction season in autumn.) Autumn weather conditions to see the scene can generally start the next day to move on to the next step), you can start painting. There is no difference between the painting method of the paint and the method of painting the primer, after the first brush, and so on completely dry paint film molding, and then brush the second time.
General paint brush twice the best effect, if it is dark paint, but also pay attention to reduce the addition of water or no water (primer and finish water added must pay attention to the technical requirements, different paint requirements are different, the general barrel will be explained. Too much water is a common problem, will lead to bad paint film molding, late prone to powdering off and other problems), sometimes in order to the best results need to brush 3 to 4 times. During the maintenance of the paint film should pay attention to the protection of the paint film, try to avoid the pollution of external pollutants, as well as mechanical bumps.
according to these standards, you can generally judge whether the construction team responsible for construction is professional, can also be used as a reference for process acceptance. Autumn is the construction season, and autumn pleasant weather relationship is relatively large, less rain, suitable temperature, moderate air humidity, multi-process benefits, in the construction effect and length are of great help. And according to the schedule calculation, can generally be completed before the winter weather changes, but also avoid the end of the busy work period, which is more and more people will be the main reason for the decoration schedule into the autumn.
