Wall problem one: bubbling
Sometimes there will be blister-like protrusions on the wall, and it will contain sand particles that will fall off when touched. The cause of wall foaming is that there are too many pigments added in the paint preparation or mixed with debris; the paint bucket, brush, roller or spray gun is not clean; before the paint surface is completely dried, the moisture penetrates into the paint and the paint film loses adhesion. ; the wall surface is not cleaned when the wall is painted.
In order to solve the problem of wall foaming, first of all, avoid the seasoning in the humidity or the weather, and the time interval of the number of times of brushing must be applied after the putty or the paint film is dry, before the paint is applied. Clean up the construction environment and clean up the painted objects.
When bubbles appear on the wall, all the foaming and peeling parts should be removed first. However, if it is caused by the putty on the wall base, you need to remove the putty and choose a suitable putty to scrape it again. Local wall foaming can only be partially scraped, and the edge of the scraped part is smoothed, then the primer is applied and repainted again; if it is a large area of ​​foaming, it must be scraped off, wait until the wall Construction will be carried out when the surface is dry.
Wall problem 2: peeling
Sometimes the decoration is completed soon, and the phenomenon of floating and falling of the putty on the wall appears. The main reasons are poor construction technology, poor adhesion of the putty, paint and shrinkage.
The quality of the construction process requires a professional construction team and experienced construction personnel, which reminds us to be cautious when looking for a decoration company, not to be cheap.
The solution to this problem requires reinforcement of the base layer, shovel the wall surface of the peeled area, completely remove debris from the wall surface, and repaint the putty and paint.
The paint used for the inner and outer walls is different. The interior wall latex paint has high requirements for scrub resistance, and it is easy to soil the wall in the home life, and can be wiped with water at any time. Exterior wall paint can be used for interior wall painting because it also has water resistance, while interior wall paint does not have anti-sun function, so it cannot be used to paint exterior walls.
Wall problem three: cracking
A wall problem that occurs before the wall is peeled off is the cracking of the wall. Spider-like cracks appear on the wall a little bit until they are connected together, causing the wall to fall off. The cause of cracking of the wall may be caused by the shrinkage of the putty. The putty is scraped after the putty is not dried before the construction. The second time the putty is not dried, the paint is sprayed, causing the crack of the dry layer of the putty.
The remedy for cracking can put the adjusted putty and paint on the crack, but it cannot be completely eliminated. To prevent this from happening, the plaster should be dried and then scraped again during the construction. The thickness of the putty should not exceed 2 mm. When reworking, the crack should be scraped first, then scraped with putty, and the top coat should be painted after the putty is dry.
Wall problem four: moldy
Because the room is too humid, or is soaked in water for a long time, the wall surface is prone to spotted mildew, or a large area of ​​mold, and some may even grow moss.
The moldy treatment of the wall must first scrape off the moldy wall skin with a scraper. The scraped area is larger than the moldy area, and then aired and aired to ensure that it is not wet, which is beneficial to the later repair work. Clean the wall surface that has been scraped off the wall and apply the adjusted putty powder. After the putty is dried, apply lime. The lime can absorb the moisture and keep it dry. Then apply the waterproof coating and latex paint, and finally polish the wall. Just fine.
If every step is done strictly as required during the renovation process, there will not be so many problems later. Therefore, prevention is far more important than remediation. The selection of construction teams must be serious.
