With the passage of time, wooden doors lose their color and suffer small impacts that gradually deteriorate them. Although wood is undoubtedly a noble material, it is so well true that it requires some periodic maintenance and that it is affected by humidity and water. For this reason, many new houses are opting for other more resistant materials with a long useful life, most made with some thermoplastic. If we are faithful to wood, we have a door with a special value, or we simply do not want to face the cost of replacing them, we can restore wooden doors in a simple way and without incurring a large financial outlay.
Restore wooden doors in 4 steps
Restoring doors is easy if you know the steps to take and offers good results, although it should be remembered that it is something that must be done periodically.
1. Remove the old paint
Although it seems obvious, some people still paint directly on top of the old paint, which becomes a guarantee of a defective finish and a poor restoration. First of all, all the hardware (doorknob, lock and hinges …) must be removed from the door, being careful not to leave marks. We can choose between several techniques to remove old paint, such as applying abrasives, using chemical strippers or using heat systems, called ‘thermal’. The latter are the most recommended because they are the safest, by avoiding the toxicity of abrasives by inhalation, and because they also offer great results. The system consists of applying heat with an air gun, in such a way that the paint is withdrawn by itself on contact with the heat. By helping us with a spatula we can separate it without difficulty.
To ensure that the surface of the door that we are going to paint is uniform and smooth, and to also remove the remains of the previous paint, we will sand the wood. With a fine or medium-sized sandpaper, we will leave the door ready for the new paint that we have chosen. A triangular sandpaper can come in handy for some difficult access angles.
3. Correct imperfections
When restoring wooden doors it is important to pay attention to whether the door has any small holes or cracks, which we will take advantage of to fix so that the restoration is complete. With synthetic resin putty, which we can buy at any hardware store, we will solve it. We just have to apply it at each point and let it dry and then sand it. Of course, do not forget to buy the putty of the same color as the new wood paint.
4. Several coats of paint
A common question that often appears when restoring wooden doors is how many coats of paint are necessary to obtain a good result. Although it depends on the shade we are looking for, except in exceptional cases with 2 or 3 layers will be enough. Of course, we must make sure that before applying it we have put two things on the door; on the one hand, a layer of wood preservative and on the other, a sealer, which will ensure that the paint sticks well. Products to protect wood The place where the door is located (interior or exterior), its exposure to the sun and the quality of its wood will directly influence its deterioration. To protect the wood while maintaining its good condition, we can choose three products. These are the varnish, oil and decorative protectors. The first, widely used indoors, protects wood well, but has the disadvantage that it can crack. The oils are usually applied periodically in order to nourish the wood. The decorative protectors, on the other hand, do not crack and protect well both from the effect of sunlight and from water and UV rays from the sun. They penetrate the wood and offer a natural finish.
