The first two methods are not really suitable for indoor work, especially if you can not remove the door for a while and work outdoors.
The third way to remove old paint from the door is more optimal, because there is almost no smell compared to the heating of the paint with a hair dryer, and the dust that tends to fly in different directions, when removing with brushes and power tools.
It is worth noting that cleaning with metal nozzles (brushes) on the angle grinder or drill, requires careful control nag and suitable for working with metal surfaces.
When you remove old paint from the wooden surface with a metal brush, the possibility of damaging it, making grooves and recesses is practically 100%. Which will ultimately affect its appearance and will only add extra work to puttying, sanding and leveling the plane of the door.
If it is not possible to dismantle the old door, you can try the following method, which guided the removal of paint from the door.
First of all, purchase a special wood paint remover. According to the instructions applied it to the door, but the result was weak. The reason was the abundance of varnish and paint coats that were used on the wood of the door.
Then I used a putty knife and a heat gun, which I had also bought specially for this purpose. Its cost is low, and the speed of cleaning has increased many times.
There are several recommendations for working with a heat gun when removing old paint from a wooden door, as well as safety techniques that are important to follow.
The main recommendations are:
- Safety Precautions Be sure to use safety glasses, and follow the recommendations in the manual for your tool.
- Spatula should not be too soft and wide. Using a soft spatula I had to wait a long time until it could pick up the paint. After several minutes of unsuccessful attempts, it was decided to use my grandfather’s old trowel. It did a great job.
- The force of pressure and the angle of the trowel oddly enough, but it also played a role.
By overdoing the force of the trowel, it was easy enough to damage the surface of the wood, picking up the old paint and wood fibers along the way.
But in my case it is not so terrible, since this door of the utility room on the summer cottage. It is many years old, and as it turned out, the door already had a lot of cracks, dents and other things
I had to use putty in the end.
Getting the angle right (about 25-30%) was half the battle, because it took off a longer layer of paint at a time, which also speeded up the process.
You will be able to find the best distance yourself, depending on the power of the heat gun and the weather conditions, such as wind (if the work is done outdoors).
Note how soon the old paint layer begins to swell. Once you notice the difference, you will realize that this is the required distance.
Do not keep a construction hair dryer in one place for too long. Progressive motions in the direction of removing the old paint from the door, will be most effective. The paint comes off with tapes.
After completing the removal of paint from the door and puttying defects, the final step was the processing of sandpaper.
If resin from the wood pores protrudes on the surface and it clogs the abrasive, you can use acetone and a rag. After removing the tar stains, sanding will become much easier.
A few words about the heat gun I bought.
In addition to working on the old door, he survived a fall from a stepladder and cleaning paint off the windows, also wooden.
