Today, when carrying out repairs or, for example, when restoring furniture, all kinds of varnish and varnish products are mandatory. The popularity of such materials is explained by the fact that with their help you can quickly and efficiently change the interior of the room or give the old substance a completely new look.
Moreover, in the course of such work, many people have a question, how compatible are different types of paints and varnishes. This is what will be discussed in this article.
Compatibility Determination Method
So, if you need to paint a coating for a start, you should choose exactly the material that will best match the previous layers already applied to a particular surface.
After all, if this is not done, then the new paint may simply not stick to the old one in the necessary way. And this means that after a short period of time it will be necessary to again apply a coat of coatings.
At the same time, it is clear that the exact same material that was used during the first painting is best suited. However, unfortunately it often happens that finding the right paint is simply not possible. It is at this moment that the question arises: is it possible to combine different types of coatings?
The first step is to find out in detail what kind of paint was applied for the first time. Not every person can conduct such an assessment and therefore it may be necessary to attract a specialist who can do this.
At the same time, during the identification procedure, various techniques are used from scratching the surface to heating a certain part of it. There are simpler methods, for example, you can treat part of the coating with white alcohol. If in this case the coatings of the first layer do not react in the same way, then either alkyd or oil formulations were used.
If the layer begins to decay and thin, then latex or acrylate paint was used. Another option is the use of alkali, it just acts on oil paint, causing it to lose brightness.
In any case, before applying a layer of paint on top of the old one, you need to understand what it consisted of. Only this ultimately allows you to choose exactly the material that will be most effective.
How to work with the old coating
After checking and finding out what material the first layer consisted of, the selection of a new paint should begin.
However, it must be said that before starting a new painting it is desirable to treat the surface, in a special way trying to remove the old layer as much as possible.
- If the coating consisted of alkyd enamel, then first you need to try to remove it with sandpaper and a solvent. After that, apply a primer layer, and already further you can use acrylic and latex types of paints. They allow you to effectively cover the old base.
- As for oil paints, as practice shows, other types of coatings can be applied to them, but in this case it is also necessary to clean the surface and, of course, be treated with a primer.
In addition, it is worth noting that now on many packages manufacturers publish special tables that allow you to understand with what material a particular paint can be combined.
Thus, before starting work, you will have to answer the question for yourself, using the above steps, which type of paint is suitable in your particular case?
