What is polish paint?

Before going to the method of applying polished colors on building doors, we would like to introduce you to the nature of polished colors. What are these colors and how are they produced?

Basically, polishing colors are based on unsaturated polyester resin. That is why they are the best option for painting wooden surfaces such as doors. Wooden door can be made more resistant, harder and shiny by using polishing paint. When you apply a polish on the door, you increase its resistance to water and chemicals.

These polish colors have special electricity due to the use of substances such as peroxide and cobalt. To make them, you have to combine these two materials in the required proportion and get the desired color.

Polishing steps

If we want to have a brief reference to the steps of polishing work, we should say the following:

In the following, we have mentioned in detail about the polishing painting of wooden construction doors:

First step: cleaning the wood surface

As we mentioned, before anything, the desired surface should be smooth and uniform. If your wood has any bumps, dents, dents, or splits, you will need to repair it. If the wood you are looking for is old and has many problems, you should modify it in the following ways:

We take a piece of wood that has a triangular cross section and stick it on the sunken points. To do this, we must use wood glue. Then we stick it on the sunken points and then using a grater, we smooth the parts that protrude from the surface of the wood. In any case, for painting it is necessary that the surface of the wood is smooth and uniform and does not have any dents or protrusions.

Sometimes the surface of the wood may be full of cracks or splits. To fill such cracks and gaps, we can use a mixture of sawdust and glue. We mix these two ingredients together until a kind of soft putty is obtained. Then, using a spatula, we draw it on the cracks and crevices until the desired surface is smooth and uniform. Then let it dry.

Another way to fix old wood defects is to use epoxy resin or polyester skin and polish. This method, which is very practical and innovative, can solve wood defects well. First, we must pour some resin into a container and then add hardener to it. We stir this mixture to obtain a kind of solution. Then we pour it into the cracks and crevices so that they are completely uniform with the surface of the wood. Sometimes it is possible that the surface of the wood is perforated. In this way, when we pour the solution, it may leak from the other side. In this situation, it is better to cover the other side of the wood with paper glue. We wait for a while until the desired solution is completely dry and then we start the sanding operation.

Do not forget that this step is very important. Because if the surface of the wood is not uniform and smooth, the painting will not be clean and accurate and the surface of the door will be uneven.

Second step: putty

In this step of polishing the wood surface, we have to go to putty. You must have heard that in order for the coloring to be uniform, the desired surface must be puttyed before anything else. It is the same with the polishing painting of building doors. For putty work, you need to make sure that the surface of the wood is clean and uniform. Then we use various colored powders and mortar to prepare the putty mixture. Finally, we putty the surface of the door using a spatula.

The important point here is that putty depends a lot on the type of color that you want to apply on Wooden door. If your wood is old, naturally you should use more resistant putties. In general, there are three types of putty for painting wooden doors:

In fact, this step of painting is done to make sure that the surface of the door is smooth and even. In this way, the gaps that you could not fill in the cleaning phase will be completely closed with putty, and in this way, the desired surface will be ready for painting.

Third step: sanding

After the putty work is finished, it is necessary to repeat the sanding operation once more. Don't forget that this operation is very important anyway because after puttying, the desired surface may still not be the same.

But do you know what sandpaper is? If you have ever seen sandpaper up close, then you know very well that this device is a kind of cloth or cardboard that is covered with silica grains. In this way, the desired surface will have ridges.

Now, the important point here is that the smaller the silica grains that are attached to the surface of the sandpaper, and the larger their sizes, then the sandpaper you want will be rougher and its number will be less.

Be careful that for the sanding operation, you must let the putty dry. Otherwise, the whole operation will be in vain. To do the sanding, we need to drag it on the wood enough to reach its surface. In this way, the extra putty is removed from the surface of the wood, and the desired surface will be completely ready for painting.

Sometimes it may be a little more complicated to paint the door. For example, let's not paint parts of the door surface. In this way, it is enough to cover those parts with paper glue so that the paint does not reach them.

The fourth step: the beginning of coloring

The most important thing you should know about the process of painting building doors is that it has several stages. One by one, these steps are very important, and failure to do any of them will lower the quality of the work:

work lining

In the first step of painting the door, after sanding, we have to go to the primer. In fact, before applying the desired polishing color on the door, you must use a type of paint called a primer. Usually, the most common lining color available in the market is Shapan, which is produced in brown and black colors. You can use these two colors to create different color ranges. The important point here is that the solvent for Shapan paint is gasoline. To do it, just use a lint-free cloth.

Sealer cover

In the next step of painting the door, you should go for the sealer coating and cover the surface of the door with it. But what is the benefit of this work? In fact, the sealer prevents the color from penetrating into the wood. That is why you must take it seriously and do it. To cover the wood with sealer, just mix it with thinner and apply it on the surface of the door with a soft brush.

sanding

After the sealer coating is finished, it is time to sand again. Because the work surface has become rough again and it should be smoothed and polished. That's why you need to have several types of sandpaper on hand to paint the door.

Killer performance

One of the most important stages of door painting is covering its surface with killer. Killer is a substance that you can combine with different colors and put on the surface of the door. In fact, it is with the use of killer that you can achieve different color tones. Dilute the killer with thinner and apply it on the surface of the lid using a brush.

Final coloring

In this step, we have to apply the last color we have chosen on the door. It is usually recommended to use half polyester instead of killer. Because it has a much higher quality and increases the resistance of wood against various factors. It is also available in two types, matte and glossy, which will naturally open your hand to choose. The solvent of these colors is also thinner. Of course, you should not forget that semi-polyester performance is much more accurate and sensitive than killer, and the time intervals between its dyeing sessions must be chosen very carefully.

polishing work

For polishing, it is better to let the paint on the door dry completely first. Then polish it with a polisher.
