Transportation issues
During the transportation, it is necessary to prevent the decoration materials from being exposed to rain or moisture. Considering that there is much moisture in the rainy season, some wood products and plaster lines should be left in place when leaving the seams.
Paint should avoid rainy days
1, wood lacquer: For wood products, whether it is brush varnish or nitrocellulose paint when mixing, do not carry out when it is raining. Because the surface of wood products will gather a layer of water vapor in the rainy day, if paint is applied, water vapor will be trapped in the paint film, making the surface of wood products cloudy and unclear. For example, nitrocellulose lacquer on rainy days will lead to uneven color, while brushing will cause whitening. If it is necessary to meet the deadline, a certain amount of white powder may be added to the paint. White powder can absorb the moisture in the air and accelerate the drying speed, but it will also have a negative impact on the quality of the project. So under normal circumstances, even if the construction team has to do something else or stop working for two days, it should not paint as much as possible on rainy days.
2, latex paint: rain wall paint brush latex paint should pay attention to extend the wall after the first pass after the dry time. In general, the normal interval is about 2 hours, and the rainy days can be extended according to the weather conditions. Scraper putty can be used as early as some processes need to have a dry process, such as the wall putty scraper above the wall, each pass through a period of drying, each time dry and then can be scraped again, it is more difficult to dry in the rainy season. After a putty has been scraped, it is not uncommon for a week to be dry. Therefore, during construction, this process should not be carried out when the project is nearing the end of the project. It is better to arrange it early so that the interval can be longer to allow it to dry. If you are unlucky enough to encounter continuous rain, the air is too humid and the wall is not easy to dry, you can use the sun light to illuminate the wall surface, so as to promote its drying as soon as possible, to avoid problems such as yellowing, bubbling in the future.
Special reminder: Putty putty usually takes 1-3 times, during which the normal dry time is 1-2 days. When puttying is done on rainy days, use a dry cloth to wipe off the wall vapour to keep the wall dry as much as possible.
Short circuit to moisture to prevent
When rainy days are renovated, attention should be paid to the standardized operation of the circuit transformation, especially in places where balconies and other places are prone to rain and rain. Be sure to wrap copper wires that are exposed on the outside of the wires when they are not buried to prevent the wires from getting wet. Short circuit. This should be taken into account when it comes to wires that surround wood products such as damp wood keels and large core boards. If you do not care about these parts, it is likely to cause a fire. If it is rainy, you can adjust the process. For example, the waterway renovation in the pre-renovation period is an indoor project, so it is not affected by rain.
Special reminder: In thunderstorm days, the circuit renovation in home renovation must be stopped, otherwise it is very dangerous.
Cement moisture treatment
Cement easily absorbs moisture from the ground and causes moisture in the air to cause agglomeration. After agglomerated cement tiles are used to cause emptying, cement should be kept away from the wet sand after entering the site. The cement should be placed on dry ground or Place a layer of plastic cloth before placing and cover the cement with a protective film. The cement in the basement is prohibited.
Drying wooden materials
At the construction site, bundles of wooden materials should be opened for a few days to allow the package to be air-conditioned for a few days to bring it closer to the air humidity. The wooden material has a water content of less than 12% at the time of shipment. The humidity of the air during the rainy season is more than 40%, which is quite different. It is easily deformed.
