User decoration teaches you how to maintain and refurbish wooden doors

First, the base material does not hurt the overall situation on the wooden door refurbishment Everyone will be concerned about the problem is that the wooden door was originally used oil paint or water-based paint, if you do not use the same kind of paint renovation, whether it will lead to poor quality. Experts said that there is no need to worry about this issue.

In general, there are three types of oil paints, polyester paint, nitro paint, and alkyd paint. Alkyd paints are older products that dry slowly and are used less and less in decoration. The nitro-lacquer dries quickly but the film is thin. It needs to be brushed many times, and the humidity is very large and it is easy to whiten. Polyester paints are used relatively more, filming faster and with better results.

If you originally used oil paint, consider using the same kind of paint, or consider using water paint. In general, the use of the same kind of paint will be relatively good adhesion, with the exception of polyester paint. If the original paint polyester paint, and then later paint polyester paint, the original film needs to be melted in order to have good adhesion. One problem with this refurbishment is that the adhesion between the refurbished paint film and the original paint film will not be very good. If the new membrane is damaged, such as being cut by a sharp object or a pit, and following a crack or pit, it will cause the two surfaces to peel off. The water-based paint is relatively more environmentally friendly, and the renovation of the wooden door is carried out in the room. The smell of the oil paint is relatively large and it is difficult to volatilize. It is recommended that you use water-based paint for renovation.

It should be noted that if the wooden door is refurbished, the longer the first time the paint is sprayed, the better. As the refurbishment takes place, the original substrate is already dry and will not affect the repainted film. If it is a wooden door just bought, it is recommended not to spray it first. Because if the odor is large, it does not dry out, resulting in poor adhesion of the paint film.

Second, dark oil is not easy to cover because of any substrate and material can be renewed, want to change the color naturally is not a problem. In paint stores, consumers can choose the color they want based on the color card. However, it should be noted that if the oil was originally used and the color is dark, it cannot be covered with light paint unless the original color is covered with a darker color. If the original is mixed with oil, there is no limit to the color, and you can change it to any color.

Third, the sandpaper repair damaged If the wooden door surface damage, such as cracks or broken a pit somewhere, you should first put the place of destruction putty putty, and then polished sandpaper, then brush the primer and topcoat.

If the grass is not damaged, consider painting it directly. The correct procedure is to sand the original wooden door with sandpaper and then apply the primer and topcoat directly. Because the finished product door is waxed, there will be grease on the surface. After grinding it again, the paint adhesion can be improved. There is no difference in quality between refurbishing and first painting. There is no need to worry about shorter life or other quality problems.

Fourth, pay attention to the construction of the three points for the film after the effect of paint quality and construction will have a certain impact. Oil paint is generally OK, normal construction can be.

In the water-based paint construction, workers often make the following mistakes, affecting the construction results:

1, in general, spray paint brush twice primer three times, but each time you need to interval 4-6 hours to brush the second time the paint, workers in order to fast, every 1-2 hours to brush the second time paint The paint film did not dry out, affecting the final results.

2. The water is not properly mixed according to the instructions. The amount of water exceeds a reasonable ratio and affects the filming effect.

3. During the construction, workers will use coarse sandpaper for the sake of drawing, but fine sandpaper should be used to polish more finely and the adhesion of the paint film is better.
