Wet weather, dry and so on for the wall is a test, is the most prone to problems on the wall. In the rainy spring wall is easy to appear some problems such as bubbling, cracking and so on. These problems are of course related to the weather, but most of the reasons are still caused by poor decoration materials and techniques. The following by us to introduce solutions to common problems on the wall, I hope to help you.
Wall problem one: foaming
Sometimes the wall will have a bubble like protrusion, but also contain sand, a little touch will fall. The cause of the wall bubbling is to add too much pigment in the paint deployment or mixed with debris; Paint buckets, brushes, rollers or spray guns are not clean; Before the paint is completely dry, the moisture penetrates into the paint, causing the paint film to lose its adhesion. When brushing the wall, the wall is not cleaned up.
In order to solve the problem of metope bubbling, first of all to avoid in the humidity of the season or weather for brushing, then brush times interval, must wait for putty or paint film dry after coating the next layer, and clean up the construction environment before the paint construction, and clean up the object of brushing.
When bubbles appear on the wall, all bubbles and peeling parts should be removed first, but if the problem is caused by the putty on the base of the wall, you need to remove the putty, and choose a good putty to scrape again. Local wall foam can only do part of the scraping, and the scraping part of the edge grinding smooth, and then on the primer, and then paint again; If it is a large area of bubbling must be all scraped off, until the wall dry when the construction.
Wall problem two: mold
Because the indoor is too humid, or long-term water immersion, the wall is easy to have spots of mold, or a large area of mold, and some even grow moss.
The treatment of wall mildew should first scrape off the moldy wall skin with a scraper, scrape off the area is bigger than the moldy area, and then ventilate to dry, to ensure that the moisture is not conducive to the later repair work. The wall skin has been scraped off the wall cleaning, coated with good putty powder, putty dry and then coated with lime, lime can absorb moisture, keep dry; Then on the waterproof paint and latex paint, finally grinding the wall can be.
Wall problem three: cracking
Before the skin of the wall, one kind of wall problem will appear is the wall cracking, spiderweb cracks appear on the wall little by little until they join together, causing the wall to fall off. The reason for the wall cracking may be caused by the shrinkage of putty. In the construction, the first putty is not dry before scraping down the putty, and the second putty is not dry before painting, resulting in the cracking of the layer behind the putty dry.
The remedy of cracking can be adjusted putty, paint on the crack, but can not completely eliminate. To prevent this problem, in the construction should wait for a putty dry again after scraping again, each time the thickness of putty should not exceed 2 mm. When reworking and repairing, the cracking should be scraped clean first, and then repaired with putty. After the putty is dry, the finishing paint should be painted.
Wall problem four: peeling
Sometimes the decoration is completed soon, the wall will appear into blocks of putty floating, falling phenomenon, the main reasons are poor construction technology, putty, paint adhesion and shrinkage performance is poor.
The quality of the construction process needs a professional construction team and experienced construction personnel, which reminds us that we must be careful when looking for the decoration company, do not covet cheap.
The solution to this problem requires the reinforcement of the base, the peeling area of the wall after shoveling, thoroughly remove the debris on the wall, brush putty and paint again.
The paint applied to the interior and exterior walls is different. The interior wall latex paint has high requirements on the performance of scrubbing resistance. It is easier to dirty the wall in household 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, and interior wall paint does not have sun resistance function, so it can not be used for exterior wall painting.
