The aging of doors and windows is the most common problem encountered in the decoration of second-hand wedding houses. So, what are the construction points for the renovation of second-hand houses and windows? First, the sandpaper is sanded and repaired and damaged. If the surface of the wooden door is damaged, you should first put the putty on the damaged place, then sand it with sandpaper, then brush the primer and topcoat. This is because, in general, the finished door is waxed, and the surface will have grease. After polishing it, it can improve the adhesion of the paint. There is no difference in quality between refurbishment and first-time painting, so don't worry about shorter life or other quality problems. Second, the base material does not hurt the overall situation. One problem with wooden door refurbishment is that the wood door was originally made of oil-based paint or water-based paint. If the same type of paint is not used during renovation, it may result in poor quality. Experts say that this issue is not a concern. In general, there are three types of oil paints: polyester paint, nitrocellulose paint and alkyd paint. Alkyd paint is an early product, it is slow to dry, and it is used less and less in decoration; nitro paint is dry quickly but the paint film is thin, it needs to be brushed many times, and it is easy to white when humidity is high; polyester paint It is used more often, and the film formation is fast and the effect is better. If you are using an oil paint, consider using the same paint or water-based paint. It should be noted that when the wooden door is refurbished, the first time the paint is sprayed, the better. Third, dark oil is not easy to cover. Although any substrate and material can be refurbished, if the original oil is used and the color is darker, it will not be covered with a light paint when refurbished, unless the original color is covered with a darker color. And if it was originally mixed, there is no limit on the color, and you can change it to any color.
