What types of paints can be used for outdoor work when finishing basement structures made of concrete?

The durability and aesthetic appeal of concrete basement structures greatly depend on the type of paint used for finishing. Concrete surfaces can be subjected to harsh weather conditions, so it’s critical to use paints that are specifically made to withstand these conditions.

For these uses, a variety of paint kinds are appropriate, and each has special advantages. Paints that provide waterproofing are excellent at warding off moisture, which can be a big problem for basements. They establish a barrier that stops water from penetrating the concrete.

Elastomeric paint is an additional choice that is renowned for its adaptability and capacity to hide fissures. This kind of paint reacts with the concrete, expanding and contracting to keep the finish robust and long-lasting. Epoxy paints offer a high-performance, glossy finish that is stain- and cleaning-resistant for those seeking a more ornamental touch.

Selecting the appropriate paint requires taking into account variables such as weather, anticipated wear and tear, and personal taste. You can make sure the concrete structure in your basement is safe and attractive for many years to come by choosing the right kind.

Is the material suitable?

It is thought of as a kind of designer decoration by people who are unfamiliar with the characteristics of paint materials. Although it brightens and enhances the base, decorativeness pertains to the paint’s secondary use.

Finishing a concrete base serves the primary purpose of shielding this area of the structure from:

1. External influences. These include precipitation, temperature changes, high humidity, direct sunlight, wind.
2. Pollution. The dirt that gets on the surface of the base contains many aggressive chemicals. They also affect concrete, causing various types of corrosion – general acid, carbon, leaching corrosion.
3. Vital activity of pathogenic microorganisms. These include fungi, mold, and colonies of small insects.

The primer and paint layer that has been applied acts as a good insulator, keeping the building from becoming cold.

When it is not recommended?

The concrete base must completely dry before beginning any painting work. The solution takes 30 to 60 days to dry. Thus, you can begin painting the base no sooner than one month following the plastering’s completion.

It is only permitted to use paint that contains a solvent after a year and at a minimum temperature of +5 °C.

The base will show efflorescence or white spots if you disregard these instructions. It is challenging to get rid of them. Additionally, the top layer of plaster may crumble during the first frost.

Characteristics

The house’s basement necessitates meticulous consideration when selecting paint. A comprehensive set of attributes is necessary for the facade coating to guarantee superior protection:

1. Water resistance. The description of the material must indicate a high water repellent coefficient.
2. Fire resistance. This parameter is very important, especially for buildings with metal trim or made of corrugated sheets. Also, the material should not emit corrosive substances even during combustion.
3. Vapor impermeability. The presence of such a characteristic allows you to effectively remove internal vapors to the outside, which is the key to a comfortable microclimate in the room
4. Resistance to changes in external temperature. A significant nuance, because the paint for painting the base is exposed to all possible influences. It must maintain its integrity without cracking.
5. Resistance to sunlight. Exposure to ultraviolet radiation reduces the saturation of the paint color. The more resistant the material, the longer the base will retain its attractiveness.
6. A range of shades to choose from. The more shades in the proposed range, the easier it is to choose the right color.
7. Aesthetics. Necessary to give the base a presentable appearance.

The paint’s ability to interact or adhere to the concrete coating is another crucial factor. The paint’s durability, practicality, and environmental friendliness are among its other qualities.

What is the best paint to use?

The best choices are elastomeric paints, which are renowned for their durability and waterproofing, and acrylic paints, which provide flexibility and resistance to cracking. For many years to come, both varieties guarantee that your concrete basement structure will be both secure and aesthetically pleasing.

Step-by-step instructions for painting

If the house is brand-new, you must first confirm that the concrete has dried. It is not advised to apply some paint types to wet surfaces. There are subtle differences when working with different paint types.

But before painting, there are a few general things that need to be finished:

1. Cleaning the surface of the base. It must be cleaned of traces of dirt, dust and remove traces of mold (if any).
2. Leveling the surface intended for painting. If there are depressions or cracks, they must be filled with a concrete-based putty mixture.
3. Treating the surface with a primer mixture. It is better to apply several layers with intermediate drying.

A few details to consider when painting are as follows:

• when working with large surfaces, it is recommended to use a roller or spray gun;
• In hard -to -reach or relief places, it is better to use brushes of various widths;
• The optimum temperature for staining the basement is from +5 ° C to +30 ° C., humidity – up to 80%.

On the packaging, the manufacturer provides instructions on the subtleties of using a particular kind of paint. It takes time to paint the base. It is advised to use two to three layers.

Wherein it’s crucial to give each one time to dry. Usually, three to five hours pass. The largest helmet size needed to cover the first layer. The consumption drops with each additional layer.

To avoid having to hunt for the perfect color when the paint runs out unexpectedly, you should purchase paint in batches plus a little extra.

The manufacturer prescribes how long you must wait. You must begin with areas that are uneven and shaded. The reason for this is to give them more time to dry. If the surface is level, you will need to use a spray gun or roller. Brushes are used to paint problem areas.

It is necessary to replace the removed soil after the final coat of paint dries. After that, carefully fold and wash the tool. Send the remaining material for storage in a dry, warm room after securely closing it.

Difficulties

The most common omissions that occur when painting a concrete base are of the following types:

• painting uncured concrete;
• applying paint to the surface without preliminary preparation;
• using primer and paint from different manufacturers and different compositions;
• painting is done in one layer;
• when applying several layers, there is not enough time for them to dry.

Pros and cons

A concrete base can be finished in a variety of ways. You ought to understand how painting differs from other techniques. Apart from its accessibility and simplicity of use, the technology offers the following benefits:

1. Economy. It is possible to choose materials from a low price category and independently perform all types of work.
2. Speed. You can completely finish the work in 1-2 days, especially with the base of a new one Home.
3. Decorative. A range of color solutions allows you to create unique design projects and easily change them.
4. Environmental friendliness. Coating with vapor-permeable paints will allow the concrete to “breathe” and remove moisture from the interior to the exterior.

The drawbacks of a particular kind of paint are typically linked to negative traits. As an illustration:

• high cost of material;
• weak resistance to ultraviolet radiation;
• yellowing of the surface;
• fast fading.

Average cost of painting a room

The cost is determined by measuring one square meter of basement space; it ranges from 180 to 450 rubles per square meter. Market price on average is 220 rubles.
