What is acrylic primer used for and how is it applied in finishing work?
Primer is an essential base for high-quality wall and ceiling finishing. It directly affects the quality and durability of the coating. Acrylic primers vary in their application areas. For example, there are impregnating primers, special formulations for metal treatment, adhesion primers to improve bonding, and deep-penetrating primers to enhance moisture resistance.
- Improve the absorbency of the base for even and high-quality finishing;
- Have a wide range of applications (for example, deep-penetration primer is suitable for application on plaster, concrete, brick, wood, drywall, putty, and other materials);
- Strengthen the base;
- Reduce the absorbency of the base, which favorably affects the consumption of finishing materials;
- Enhance the glossy shine of enamels applied on top;
- Allow the application of lighter paints over dark bases.
Acrylic Paints — Advantages, Disadvantages, and Application Features
Acrylic Paints — Advantages, Disadvantages, and Application Features
The peculiarity of acrylic paints lies in the fact that they adhere perfectly to any surface (the main thing is that it is clean), are easily diluted, dry relatively quickly, and then remain resistant to moisture. In fact, they can be called universal, as they are suitable for all application conditions. This explains their popularity. Do acrylic paints have disadvantages, and how critical are they?
Disadvantages
These paints have practically no disadvantages, and the only more or less serious drawback is that they cannot be washed off after drying. Certain factors can sometimes become obstacles when using water-dispersion paint materials based on acrylic. It is not recommended to apply paint under certain conditions. Let’s outline the main ones:
- Strong wind. Due to strong gusts, the coating will dry unevenly, and irregularities will appear on the surface.
- Excessive humidity. It should not exceed 80%, otherwise, the liquid will not evaporate.
- Precipitation (even minor). The fresh coating should not be exposed to it for at least 24 hours.
- Exposure to scorching sun. Due to sunlight, the paint will distribute unevenly, causing irregularities, spots, and streaks.
- Low temperature. The protective film on the base will not form if the temperature is too low, leading to cracks in the coating.
Advantages
Acrylic-based paints have many advantages. Let’s consider the main benefits of such materials:
- High abrasion resistance and long service life. Many coatings last up to a quarter of a century without losing their attractive appearance.
- Suitable for both interior and exterior finishing.
- Excellent adhesion. They are suitable for various surfaces: primed, drywall, wood, brick, concrete. They can also be applied to plaster.
- Easy to apply. Even beginners can handle it without expensive tools or professional skills.
- Fire safety and resistance to temperature fluctuations. They do not crack in frost.
- No reaction to ultraviolet radiation. The coating remains bright for a long time.
- Allows natural air circulation. Surfaces breathe, preventing mold in rooms.
- Water resistance after drying. Suitable for kitchens and bathrooms. The coating is easy to clean.
When the fresh coating dries, only water evaporates. Such interior paint has no unpleasant odor.

To achieve a good result when painting, it is necessary to choose the right paint depending on the type of room and surface. There are several types of paints for finishing work, each with its own characteristics and advantages. What paints are used in finishing, what are their features, and how to apply them?
- Oil paint. A traditional solution known for its durability and reliability. The composition of such paint includes pigments, fillers, and binding linseed oils. It is most often used for finishing toilets, bathrooms, and kitchens, as it can be washed. You can choose matte or glossy paint, and it is easy to purchase.
- Water-dispersion paint. It has water-repellent properties. The composition includes a suspension of binders and an aqueous solution. This paint has no specific odor, adheres well to any surface (except for glossy paint coatings). A wide color palette and high durability make water-dispersion paints very popular.
- Acrylic paint. Perhaps the most popular finishing material today. It is most often used for painting walls and wallpaper. Acrylic paint also has no odor, is highly resistant to fading, and is easy to apply. This composition dries quickly and can mask small cracks in the putty layer.

- Enamel paint. There are several types of enamel paints, such as alkyd enamels and nitro enamels, which form a durable, shiny matte or glossy layer resistant to high humidity. These paints dry in 15-45 minutes. Facade enamels can be an excellent solution for exterior finishing. However, such paint is sensitive to damage, so dents and scratches may appear on its surface.
Tip:
To ensure precise color matching, it is best to use computer color matching for paints. This allows you not only to choose the right color from thousands of colors and shades but also to perform re-coloring at any time.
