Recently, Ms. Li called the hotline to complain. The house renovated last summer, this year, found that the floor and cabinets were cracked to varying degrees, but because they were looking for the "road guerrillas", they could not be guaranteed after the sale. They could only help this newspaper. After contacting the manager of the engineering department such as Lily Decoration, Mingwei Decoration and Shichuang Decoration, the reporter came to the owner's house and found that there were some signs of moldy in the cracked wall. When communicating with the owner, Ms. Li said that the materials were correct during the renovation last year. Some were moldy, but they couldn't be thrown away and bought again, so they dealt with things. I didn't expect the later problems to be so serious. According to this case, several experts said that if Ms. Li can handle the mildew materials in time, maintain ventilation, prevent moisture on the site, and control humidity, they can also install satisfactory projects.

After exposure to the sun and rain, the material of the Lily Decoration Engineering Manager Zhang Lei said that the regular construction party will select the products with qualified moisture content in the market, avoid buying exposed materials that have been exposed to the sun, rain, or rainforest. The paint will age and feel extremely dry or extremely moist, with odor. After the wood comes into the field, it should be placed for one or two days, but not in the direct sunlight area. The wood should be adapted to the humidity of the surrounding environment, and the bottom layer should be covered with moisture-proof mats or wooden blocks. Like the problem of Ms. Li’s family, the floor, cabinet and wall surface are cracked. It can be repaired in the fall and the effect will be better.

Anti-mildew must be ventilated frequently. Some people may ask how the summer decoration should prevent mildew. The chief engineer who has been engaged in decoration for many years reminds the owner to open the window frequently or remind the workers to ventilate the work in addition to supervision. In the rainy season, the wall paint can not be shortened in order to catch up with the construction period. According to the foreman, the wall surface after the latex paint is applied for 3 to 6 days, and the drying time in the rainy season needs to be increased. After 8 to 10 days, as long as the base layer is not completely dried, it must not be painted. If the construction period is urgent, in the case of allowing cross-construction, the wall treatment can be put into the construction in advance, so that it is enough to allow enough time to dry out later.
