Achieving a smooth and long-lasting finish on your walls requires careful consideration of the primer you choose. The putty’s adhesion to the surface and the finish’s longevity will depend on the primer you choose. It can be difficult to decide which of the many options available is best for your particular needs.
There are numerous varieties of primers, each intended for a specific surface and set of circumstances. Certain types perform best on previously painted walls, while others are more appropriate for porous materials. Long-term, you can save time and money by being aware of the differences.
We’ll examine the various kinds of primers that are available in this post and assist you in selecting the best one for your project. Selecting the best primer will guarantee that your walls look fantastic and endure over time, whether you’re working with concrete, plaster, or drywall.
Primer properties
One type of work that is necessary is priming walls under putty because primer has the following qualities:
- strengthens the base;
- protects the material from mechanical impacts;
- levels the surface;
- gets rid of small defects;
- glues dust residue;
- provides waterproofing of the surface;
- makes the material resistant to temperature changes;
- improves the application of putty;
- reduces the consumption of the composition;
- improves the adhesion of the surface and the material;
- prevents the occurrence of fungus and mold on the building base.
Selecting the appropriate primer for walls beneath putty is crucial for guaranteeing a glossy, durable coating. The best primers strengthen the bond between the putty and the wall surface, improving adhesion and durability. Options like acrylic, alkyd, or deep-penetrating primers are usually advised, depending on the type of wall. To achieve the best results, it is important to match the primer to the type of wall and the conditions of the area.
Advantages of the composition
Under putty primer for walls offers several benefits:
- Environmentally friendly product. The product does not contain any harmful substances that can harm the body. The only exceptions are some primers containing solvents. Such compositions cause intoxication, so they are used only for external work.
- Steady withstands temperature changes. Therefore, it is recommended to use the primer in any climatic conditions.
- Compositions, depending on the type, are used not only for internal work. They are also used outdoors.
- The primer is recommended to be used even in rooms with high humidity. The composition will provide waterproofing of the base.
Types of product
It’s best to become familiar with all types of primer in order to determine which one is better for walls under puttying.
The product is categorized based on its makeup:
- Acrylic product. Recommended for use on all types of surfaces. Drying time – 4 hours. The product does not contain solvents and harmful substances, therefore it is safe for health. The primer is odorless. It is used even in rooms with high humidity. Another advantage is the reasonable price.
- Alkyd primer. Recommended for use on wood and metal surfaces. The composition dries in 14-15 hours.
- Latex primer. Recommended for use on all types of surfaces, including loose and dilapidated ones. Drying time – 40 minutes.
- Emulsion composition. Recommended for use on all types of building bases. The composition does not contain harmful substances. It has no odor, and the drying time is 1-2 hours.
- Perchlorovinyl product. Intended for outdoor work. The composition is recommended for use on gypsum and cement building bases.
- Glyphthalic composition. Intended for metal and wooden surfaces. This primer cannot be applied to gypsum or cement bases. The primer contains toxic substances, so it is used only for outdoor use.
- Polyvinyl acetate primer. Used only for applying polyvinyl acetate paint. Drying time of the composition – 40 minutes.
- Polystyrene composition. Recommended for use under putty, as well as for wooden bases.
Additionally, the primer is categorized based on technical attributes:
- Antiseptic primers. These products contain fungicides that prevent the formation of mold and mildew.
- Deep penetration agent. The composition fills all the pores of the base and evens out the surface.
- Anti-corrosion primers. Used on metal surfaces and protect the building base from rust.
- Moisture-resistant compounds. Recommended for use in rooms with high humidity.
- Heat protectants. Provides protection of the building base from high temperatures.
Is it necessary to apply a primer after puttying?
An amateur craftsman who fixes things himself sometimes wonders if priming the walls after puttying is really necessary. Refusing to use a primer in this situation is also not advised because it has the following effects:
- improves the adhesion of the material with the finishing;
- levels the surface;
- facilitates finishing;
- provides waterproofing of putty;
- prevents the formation of mold and mildew;
- reduces material consumption during finishing.
Primer Type | Best For |
Acrylic Primer | Universal use, good adhesion, dries quickly |
Alkyd Primer | Recommended for wood and metal surfaces |
Polyvinyl Acetate (PVA) Primer | Best for dry environments and drywall |
Epoxy Primer | Ideal for concrete surfaces, moisture resistant |
Shellac Primer | Great for sealing stains and odors |
A smooth and long-lasting finish on walls under putty depends on the primer used. It guarantees that the putty sticks firmly and that there are no problems with peeling or cracking of the surface.
An acrylic primer is a dependable option for the majority of walls because it provides strong adhesion and versatility on various surfaces. Extra stability can be obtained by using a deep-penetrating primer when working with porous or chalky walls.
Don’t forget that the kind of primer you use needs to be tailored to the particular requirements of your wall. You’re setting the stage for a successful and long-lasting wall finish by choosing the right primer.
