What should be paid attention to when repainting wooden doors

<p>Many families will renovate their homes when they get married or have a happy event, which implies a new weather. Doors and windows are generally not replaced during refurbishment, because this is not only cumbersome to replace, but also increases costs, so wooden doors are generally repainted. Runcheng Chuangzhan will introduce the precautions for painting<a href="https://www.solidwoodendoor.com/" rel="noopener noreferrer" target="_blank"> wooden doors</a>.</p><p><br></p><p>One issue that everyone will pay attention to when renovating a wooden door is that the wooden door used to be oil-based paint or water-based paint. If the same kind of paint is not used during renovation, will it cause poor quality. Generally speaking, there are three types of oil paints, polyester paint, nitro paint and alkyd paint. Alkyd paint is an earlier product, it dries slowly and is used less and less in decoration. Nitro paint dries fast but the paint film is thin, it needs to be brushed many times, and the humidity is very easy to whiten. Polyester paints are used relatively often, and the film formation is fast and the effect is better.</p><p><br></p><p>If you originally used oil paint, you can consider using the same kind of paint, or you can consider using water-based paint. In general, the adhesion of the same kind of paint will be relatively good, with the exception of polyester paint. If you paint polyester paint first, and then paint polyester paint later, you need to melt the original paint film to have better adhesion. One problem that this refurbishment will produce is that the adhesion between the refurbished paint film and the original paint film will not be too good.</p><p><br></p><p>&nbsp;If the new film is damaged, such as being cut by a sharp tool or smashing a pit, picking along the crack or pit will cause the two surface layers to peel off. The water-based paint is relatively more environmentally friendly, and the renovation of wooden doors is mostly carried out indoors. The oily paint has a larger odor and is less volatile. It is recommended that you use water-based paint for renovation.</p><p><br></p><p>&nbsp;If the surface of the wooden door is damaged, such as a crack or a pit in a certain place, you should first put the damaged part on the putty, then sand the sandpaper, and then paint the primer and topcoat. If the base is not damaged, you can consider painting directly. The correct process is to sand the original wooden door with sandpaper, and then brush the primer and topcoat directly. Because the finished doors are usually waxed, there will be grease on the surface. After polishing it, it can improve the adhesion of the paint.</p><p><br></p><p>The above is the method of painting the wooden doors we have organized, and I hope to help everyone. It should be noted that the wooden door should be cleaned when painting to ensure that the surface of the wooden door is smooth. If the surface of the wooden door has cracks or defects, it must be polished and filled before painting.</p>
