New houses and old houses, problems encountered in improper decoration, cracks and peeling on the wall, according to incomplete statistics, 60% of the interior wall surface layer will appear peeling off. It has become a problem for thousands of families.
What is the reason for the interior wall paint peeling? The general interior wall paint peeling is mainly due to the unbalanced settlement of the wall, the temperature crack, the uneven acceptance or the putty is not completely dry. The following points are summarized by interviewing professionals:
1. The putty is not completely dry, and the interior wall paint is painted.
2. The interior wall paint brush is too thick, or the paint is too thick. The interior wall coatings currently on the market are all viscous. After buying them, you need to match the water according to the product description. Follow the instructions carefully. Do not think that the viscosity is sticky, the thick coating is not easy to dry, and After drying, it is prone to skin cracking.
3, the indoor humidity is too large, do not dry it again to paint the second time.
In order to prevent this phenomenon from appearing, Xiao Bian has interviewed the painters for many years, and the following points are summarized as follows:
1. The base layer is well treated, the loose layer is shoveled off, and impurities such as floating and sinking, mildew, oil, rust and other impurities are cleaned up to reduce the influence of the outside on the painting.
2. If the wall surface is uneven and the sand grain is rough, it needs to be smoothed; if there are cracks or holes in the wall, it needs to be filled flat.
3. According to the specific conditions of the wall and the type of coating used, choose a putty with good bonding strength, especially in places where the kitchen and bathroom are more demanding. Water-resistant putty should be used. The layer of putty should not be too thick, usually by leveling the wall. The body shall prevail, and the paint must be applied after the putty is dried.
4, due to material application. Choose the type of coating to be adapted to the wall and the local environment.
5, try not to work under humidity or cold weather (temperature below 5 ° C, humidity greater than 85%), this will affect the production of continuous paint film, there will also be skin cracking phenomenon.
Straight flute taps are the most versatile. It can be used for tapping through holes or blind holes, non-ferrous metals or ferrous metals. The price is also the cheapest, but the targeting is also poor. The cutting cone section can have 2, 4, and 6 teeth. Short cones are used for blind holes and long cones are used for through holes. If the bottom of the hole is deep enough, try to use a longer cutting cone, so that the teeth sharing the cutting load are more and the service life is longer.
