Many families will experience discoloration, paint loss, and discoloration after many years of use. The entire door looks very old. At this time, the wooden door needs to be maintained, either putty or repainted, and the wooden door will not be repaired. Aging rapidly, the final life is reduced. This article summarizes the methods of wooden door renovation and maintenance. Although the inner doors of the renovated wooden doors are old, the new exterior doors have played a protective role against the wooden doors and are the maintenance of wooden doors.

Sandpaper repair damage

If the surface of the wooden door is damaged, such as a crack or a hole in a certain place, you should first put the damaged place with putty, then sandpaper, and 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, and there is no need to worry about shorter life or other quality problems.

The base material is harmless

One of the issues that everyone is concerned about about the renovation of the wooden door is that the wooden door was originally painted with oil paint or water-based paint. If the same kind of paint is not used during the renovation, 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. Nitro-lacquer dries quickly but the paint film is thin. It needs to be brushed many times, and the humidity is easy to whiten. Polyester paints are used relatively more, film forming is faster and the effect is better.

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 performed in the room. The oil paint has a large smell and is difficult to evaporate. 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.

Dark oil is not easy to cover

Since any substrate and material can be renewed, Ms. Tian would like to change the color naturally is not a problem. In paint stores, Ms. Tian can choose the color she wants according to 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.

The methods of refurbishing wooden doors are the above-mentioned ones. There are some areas that need attention in the refurbishment process: for the effect after film formation, the quality and construction of the paint will have a certain influence. Oil paint is generally OK, normal construction can be. Usually when water-based paint is applied, workers are liable to make the following mistakes and affect the construction results.

Workers make mistakes:

1. The water is not properly mixed according to the instructions for use. The amount of water exceeds a reasonable ratio and affects the film forming effect. 2. In general, the paint brush can be twice primed twice, but each time it takes 4-6 hours to paint the second time, the worker paints the second time every 1-2 hours. The paint film did not dry out, affecting the final results. 3. During the construction, the workers will use coarse sandpaper for the sake of drawing, but fine sandpaper should be used to polish the surface more delicately and the adhesion of the paint film is better.

The use of wooden doors for a long time will inevitably lead to the phenomenon mentioned at the beginning of the article, and it is not possible to replace wooden doors because of these problems. Therefore, the method of maintaining and renovating wooden doors is still necessary to learn a lesson, and learn to do the renovation and maintenance of home wooden doors.
