The key to anti-crack treatment in paint construction
In the construction focus of paint, the crack prevention of the wall is the most basic and the most important. It is very much at the joints and some joints. Due to the difference in material, cracks are often easily caused, for example, the wall of the room is newly built. With the original structure of the beam, column joints are prone to cracking, so the wall base layer often requires multiple processes:
The foaming agent is first applied to the seams to make the joints of the building impermeable and airtight.
The second is the use of special paper tape for sealing, and finally sealed with adhesive yellow tape, which can effectively ensure the stability and stability of the base layer, to avoid future wall cracking. At this point, the owner can communicate with the painter during the renovation to ensure that the grassroots management is in place.
The technical requirements for paint are high, and the man-hours are also relatively large. Taking a new three-bedroom, two-bedroom house as an example, the paint process takes about 10 days, which includes grassroots processing, mixed oil brushing, and so on. In the paint, the most worrying thing for consumers is the cracking of the wall.
Of course, some cracking problems are caused by the late putty shrinkage. When the first time in the construction, the putty is not dry enough, immediately scrape putty, and then brush the paint, it will easily lead to cracking of the surface layer after the putty dry, it is very much like now This kind of typhoon and rainy weather, in particular, should pay attention to extending the time of wall drying after the first pass. After continuous rainy days, the air is too humid and the walls are not easy to dry. If the construction is sloppy in order to catch off the working hours, it may leave sequelae. After the surface is cracked, the repair is more troublesome. First, the cracked area must be scraped first, and then scraped up with a putty. After the paint is dry, it is painted. In addition, whether or not it will crack again after repair is also a problem. Owners who are often in the construction site can also try to use the sun light to illuminate the wall surface to speed up the wall drying.
