Vinyl paints are used primarily in the preparation of media, as well as in finishing. Discover the main characteristics of vinyl paints, in which cases to use them and how to apply them.
Major characteristics of vinyl paints
Vinyl paints belong to the category water paints, as well as acrylic and alkyd paints. Regarding vinyl paint, it is said that it is an aqueous product or an aqueous phase, especially because of the water it contains. Vinyl paints are both composed of acetate and vinyl, forming an elastic resin, itself mixed with colored pigments.
As with any type of paint, the choice of a vinyl paint has certain advantages, such as:
- the possibility of clean with water painting equipment;
- the almost odorless character of the product;
- good adhesion to the supports;
- reduced risk of toxicity;
- a moderate cost.
But vinyl paints also have major disadvantages, such as:
- a low coverage;
- a risk of yellowing of the light colors;
- a limited choice in terms of ranges and colors;
- a long drying time between each layer;
- the difficulty in evaluating the number of layers needed.
Main uses of vinyl paints
In terms of decoration, vinyl paints are still relatively unknown and their use remains rare. In most cases, vinyl paints are not used in a classic finish, unlike acrylic paint for example.
The main uses of vinyl paints are as follows:
- underlayVinyl paint is frequently used as an undercoat, especially on porous and dry substrates, or on plaster;
- mixedVinyl paint is often mixed before being applied to a support and can be incorporated into the preparation of effect or decorative paints;
- alone: vinyl paint is rarely used alone (classic finish), especially because of its low hiding power, but this alternative remains possible.
Know that to obtain a successful rendering, whatever the medium, the choice of a quality vinyl paint is essential.
How is a vinyl paint applied?
Vinyl paints do not require the use of specific application techniques, but for optimal results, different steps must be followed.
First of all, it is essential to prepare the support on which you have chosen to apply your vinyl paint. To do this, it is necessary to dust the surface, then erase any asperities from the wall, using a sander or a simple sandpaper.
Once the support is prepared, then comes the application step of your vinyl paint. Often, it is necessary to apply at least two layers of a vinyl paint, for a sufficiently coverage. This phase of the work is decisive for the final result, because it is imperative to respect the drying time indicated between each layer of paint. For a vinyl paint, a exposure time of 24 hours seems to be a minimum.
Finally, to prolong the strength and brilliance of your vinyl paint, consider applying a protective varnish, once the last coat is dry.
