Expanding the "How to Renovate Wooden Doors After House Decoration" Notes for Renovation of Old Wooden Doors:

Wooden interior doors often encounter problems during usage, but they cannot be replaced due to various issues. However, it is important not to ignore these problems and let them affect the overall beauty of the doors. Therefore, proper maintenance and renovation of wooden doors become necessary. This article will provide guidelines on how to renovate wooden doors after house decoration, along with important considerations to keep in mind during the renovation process.

Construction Method of Wooden Door Renovation:

1. Sandpaper Polishing:

If the wooden door surface is damaged, such as having cracks or pits, the first step is to fill these damaged areas with putty. Once the putty dries, sandpaper should be used to polish the surface. After sanding, applying primer and finish paint is essential. However, if the base course is undamaged, direct painting can be considered. It is important to start the renovation process by polishing the original wooden door with sandpaper, as this helps improve the paint adherence. Since finished doors are often waxed, sanding the surface removes any grease, ensuring better adhesion. There is no difference in quality between renovation and the first painting. Therefore, there is no need to worry about a shorter service life or other quality issues.

2. Conserving the Base Material:

During the renovation of wooden doors, it is common to come across doors that were originally painted with oil-based or water-based paint. However, if similar paint is not used during renovation, concerns regarding the quality may arise. According to experts, there is no need to worry about this problem. Typically, there are three types of oily paint: polyester, nitro, and alkyd paint. Alkyd paint is an older product that dries slowly and is less commonly used in decoration nowadays. Nitro paint dries quickly but requires multiple coats, and it can turn white in high humidity conditions. Polyester paint is relatively more popular due to its fast film formation and good effect. If the original oil-based paint was used, the same type of paint or water-based paint can be considered during renovation. Generally, the adhesion of the same paint type is relatively good, excluding polyester paint. When applying polyester paint over the original paint, the existing paint film needs to be melted for better adhesion. One potential problem with this renovation approach is that the adhesion between the renovated paint film and the original paint film may not be very strong. If the new film is damaged, such as being scratched or hit by a sharp tool, pulling along the crack or pit could result in peeling of the two surface layers. Water-based paint is comparatively more environmentally friendly, and since wooden door renovation is typically carried out indoors, it is recommended to use water-based paint.

Precautions for Wooden Door Renovation:

1. Use Compatible Paint:

When working with wood paint, it is crucial to use the appropriate supporting products. If water-based wood paint is selected, it can be diluted with water in the required proportions. For nitro paint and polyurethane paint, it is necessary to add the relevant curing agent and diluent, following strict ratios. During the application process, it is best to have the guidance of professionals, as they can ensure the correct mixing and avoid issues like biting, wrinkling, etc.

2. Allow Sufficient Drying Time:

To achieve optimal results, it is important to allow sufficient drying time. Typically, applying primer twice and finish paint three times is adequate. However, each layer of paint should have an interval of 4-6 hours to ensure proper drying. Some workers may try to speed up the process by applying the second coat after a shorter interval of 1-2 hours. However, this can result in a paint film that is not completely dry, ultimately affecting the final outcome.

3. Consider Removing the Door for Construction:

Wooden door renovation is often carried out indoors, and it is recommended to remove the door and place it in a separate room to facilitate spraying. This approach offers several advantages. Firstly, it reduces environmental pollution by eliminating dust. Secondly, it provides a clear view of both the front and back of the door, which can be challenging if spraying directly on the door. Direct spraying may create fog, hindering visibility and affecting the overall spraying effect.

4. Proper Disposal of Leftover Paint:

After using waterborne wood paint, any remaining paint can be stored in a cool place for future use. However, due to the addition of curing agents and diluents, nitro paint and polyurethane paint can only be used once. Therefore, the remaining coatings should be disposed of correctly to ensure environmental safety.

In conclusion, the renovation of wooden doors after house decoration requires careful attention to detail and adherence to proper construction practices. By following the recommended steps, using compatible paints, allowing adequate drying time, and considering professional guidance, one can successfully renovate old wooden doors while maintaining their quality and overall appeal.

Renovating wooden doors after house decoration can revitalize the appearance and functionality of your doors.
