The temperature and humidity in autumn is very suitable for wall decoration. Whether it is putty, paint or gypsum leveling, it will dry faster. However, it is also easy to crack the wall due to excessive drying. For this situation, take a look at what methods you can prevent.
1, the interface agent can not brush too thin
When the old wall surface is treated, no interface agent is applied, or the interface agent is too thin. If the indoor humidity changes, the wall putty is likely to appear hollow, cracks, and fall off.
2, can only continue construction after dry paint film
If the first coating is too thick and not completely dry, it will begin to coat the second track. Due to the difference in the drying speed between inside and outside, it is easy to cause cracking of the coating. Therefore, it is important to keep in mind that during construction, the first pass of the paint film should not be applied too thick, and the next painting should be carried out after drying.3, putty, coating ratio to be accurate
Improper matching will affect the toughness and tension of the wall. The proportion of wall putty, latex paint and the ratio of water should be identified. For example, if the dilution ratio of wall paint is too high and the dilution is excessive, the molecular structure of the wall paint will be damaged and the tension of the paint film will be insufficient. Cracks occur.
4, paint the wall should be naturally cloudyAfter the wall painting is completed in summer, the doors and windows are usually opened to allow the walls to form a film in a short time. This cannot be done in the fall. Since the weather is already dry, the wall will dry faster and the water will be lost too quickly, and there will be the possibility of contraction and deformation. Therefore, within 1 to 2 days after the paint is applied on the wall, keep the doors and windows closed, or ventilate only in the morning and evening, and always keep the wall dry.
5, putty can not brush too thick
Putty on the wall cannot be too thick, because the air in the room is dry and the water loss is fast. It is easy to cause emptying, cracking, and wall inequality. In addition, the wall scraping putty can not rely on temperature drying, but rely on the wind to dry, so the putty must be very thin shave, you can scrape several times. The dry putty on the wall will not crack, reducing the trouble of repeated maintenance in the future.
After a period of time, the floor in the fall is shrinking and cracking. Dry weather is one of the reasons. The improper construction of the floor can easily lead to various cracking problems in the floor. Therefore, in order to prevent cracking caused by improper construction, some details of construction must be properly handled.
1, the floor should be properly preserved before construction
Before the construction of the floor, the materials need to be properly preserved. First of all, avoid disposing the floor and placing it in the vents to prevent over-ventilation from causing excessive cracks in the water loss of the floor; at the same time, avoid placing them in places where sunlight can reach directly, and avoiding them in the shade.
3, floor pavement expansion joints should not be too largeWhen the air is dry in the fall, the floor will shrink due to water loss. Therefore, the gap between the floors will become larger. If the solid wood floor leaves too large a gap during construction, it will result in larger gaps in the later period, and it is easy to collect filth and is not easy to clean. Solid parquet and laminate flooring can be seamlessly spliced ​​without the need for expansion joints.
2, the floor before the floor to be leveled
In the case of uneven floors, the floor is paved, and after a period of time, the floor is covered with glue, and the glue between the floors is easily released to create gaps. Therefore, before the floor is laid, it is necessary to clean the floor and remove grease or dust sand to ensure that the floor is flat and clean.4, pay attention to product protection after shop
Don't hurry to open the window after the floor is plastered or use air-conditioning to let the glue dry. This will make the floor dry and fragile. The floor must be allowed to adjust to the temperature and humidity of the room.
