How to paint the walls of concrete on the street and indoors

Painting concrete walls can revitalize your environment, whether they are indoor or outdoor surfaces exposed to the elements. It’s a useful and artistic project that calls for some planning and expertise. Understanding the ins and outs of painting concrete walls can make all the difference, whether you’re looking to update your living room or spruce up your backyard.

Weather resistance and durability are important considerations when painting outdoor concrete walls. If the paint job is not done correctly, it can be damaged by the continuous exposure to sunlight, rain, and other environmental factors. To achieve long-lasting results, it is crucial to select the appropriate paint type and prepare the surface appropriately. The process is largely the same whether painting your home’s exterior, a fence, or a retaining wall.

Concrete walls inside offer a distinct set of opportunities and challenges. Even though interior walls might not be exposed to the same severe elements as external surfaces, they still need to be properly prepared and painted in order to have a smooth and long-lasting finish. Adhering to the correct procedures can guarantee a polished appearance when painting interior concrete surfaces, be it garage walls, basement walls, or any other surface.

When painting concrete walls, there are various aspects to take into account, ranging from priming and cleaning to selecting the appropriate paint and application methods. We’ll take you step-by-step through the painting of indoor and outdoor concrete walls in this guide, offering advice along the way to help you get the best results. This post will provide you the information and self-assurance you need to take on your next painting project with ease, regardless of your level of experience with do-it-yourself projects or painting.

Painting of concrete walls

Painting concrete is just like painting any other surface in that regard. Using a brush or a roller is up to personal preference. Move toward the exit starting at the far end of the space.

Allow the first coat of paint to dry completely before adding the second. Applying it is simpler and quicker than the first step, and it’s crucial to create a sealed, water-repellent surface.

While latex paints should always be applied in two layers, epoxy paint can be applied in one layer. One day after staining, you can use the space. Other concrete coloring agents are not appropriate.

Is it possible to paint without plaster and putty

Determine whether painting requires concrete before considering how to paint it indoors or outdoors. The purpose of putty and plaster is to even out concrete’s porous surface. You can do this in two ways: first, by filling in small spaces and fissures; and second, by smoothing the painted surface, you can use less paint by reducing its area.

Release concrete does not require putty or plastering beforehand. However, this is significant for external surfaces because porous concrete absorbs moisture from the air very well. In the cold, it solidifies into ice, which spreads and eventually ruins concrete.

Internal and external work, what are the differences

In theory, staining on a cement base indoors and outdoors requires the same preparation. Just remember that inside the rooms, the concrete surfaces need to be shielded from excess moisture, fat, and dirt.

Concrete painted surfaces are vulnerable to damaging elements such as UV rays, strong winds, abrupt temperature changes, and atmospheric precipitation when they are in the street. Walls and other vertical surfaces are therefore painted with specific facade paints.

More challenging are horizontal planes where a lot of people walk or drive. Lister goes on to discuss painting concrete in these situations.

What paint to choose for internal and outdoor works

Two types of acrylic paint are available on the market for use on external concrete work:

  • Latex;
  • Epoxy.

Epoxy resin is a robust material that helps paint adhere more firmly to concrete and increases the paint’s resistance to damage, chemicals, mold, and moisture. The longer drying time, higher cost, and more work involved in applying "epoxy" paint compared to latex paint are minor drawbacks that are more than offset by the epoxy’s superior strength and extended lifespan.

When the temperature changes, concrete shrinks and expands! For this reason, it’s critical that the concrete paint has a small amount of elasticity so that it can move slightly without cracking.

The top ten concrete paints, as rated by both users and experts, are listed here.

  • Kilz is very textured, wear -resistant paint for concrete, suitable for protecting and reviving the tired old wood and concrete surfaces. Applied in two layers.

Made entirely of a sturdy acrylic resin, this paint is thick enough to seal in minor flaws and strong enough for both interior and garage use, including carriageways. Both horizontal and vertical surfaces can use it. possesses an anti-slip property, even on damp concrete surfaces.

  • Coloredepoxies 10002 – on epoxy resin. Suitable for a wide range of surfaces. Is a transparent epoxy coating, not real concrete paint.

Not suitable for surfaces that are continuously wet (such as those in baths, pools, etc.). However, it offers enough roughness and can support heavy loads with ease for the majority of courtyards and floors. You can tag the white base with any color.

Preparation of concrete walls for staining

Even the best concrete paint will not adhere correctly to a poorly prepared concrete surface. Sweeping is the first step in cleaning, and washing is the last. To get rid of fat spots and dirt, strong chemical cleaners can be used.

You will need to use chemical pullers or scrapers to remove any remaining paint traces from the surface.

Features of painting walls indoors

Painting concrete surfaces indoors requires careful cleaning and preparation, application of the appropriate paint, and a sufficient amount of drying time.

Concrete needs to be cleaned often indoors, especially in homes. Trinatrihosphate, available in most home chemical stores, is used to remove oil stains. In order to moisten all of the oil spots, mix it with water according to the package’s recommended ratio. Before proceeding to the following stages of preparation, make sure the concrete surface has dried completely by rinsing off the cleaner after the required amount of endurance.

Use concrete putty to fix significant flaws:

  • Cracks;
  • Potholes;
  • Irregularities.

Make an effort to ensure that the concrete is as even and smooth as possible. Any crevices and fractures allow moisture from the room’s cleaning to seep beneath the paint, causing it to peel off.

Two layers of priming are applied to the surface to ensure that the coloring composition is securely clamped to the base. Next, they paint in two layers as well. Before adding the next waterproof layer, the previous one must totally dry.

The paint takes a full day or two to dry out. There shouldn’t be any people or animals in the room right now.

External coloring of concrete surfaces

If the surface of your concrete porch, a statue, or a new path appears level, use a roller to apply acrylic latex paint without first priming. A surface up to 12 square meters is covered with 5 liters of thick composition.

Acrylic wear-resistant latex with low gloss is a great option for hiding minor flaws and ensuring a long-lasting and efficient coating because it is resistant to UV rays, abrasion, fading, cracking, and exfoliation.

Low gloss acrylic wear-resistant latex is resistant to fading, cracking, UV radiation, abrasion, and exfoliation.

Use T.N. Concrete restorers prior to painting if the concrete is old, cracked, or extremely porous. They fill cracks up to 6 mm thick and are ten times thicker. Additionally, they offer durability and glorification resistance, with a 12-year lifespan between coat changes. A frost-resistant restorer used in conjunction with paint will shield concrete from moisture over time. Up to 20 square meters of concrete can be updated with one 5-liter can of restorer.

It is made of gray or white acrylic that has been siliconized—that is, thickened with shallow sand filler—with very potent resins that, when applied to appropriately prepped surfaces, create an opaque, strong film.

Using a hard scraper, remove any spray, lumps, or uneven patches from the concrete. After that, use a brush and water to clean up any remaining dirt. After allowing the surface to dry fully, fill in all of the gaps with cavalry cement putty. There may be a need for more than one layer. Apply sealant all the way.

Apply a thin layer of concrete primer to the surface using a brush on the edges and a roller on the main surface. Allow it to dry; each layer takes about two hours to do this. Priming two times is advised to achieve the desired outcome. Apply paint in the same manner.

In conclusion, we can state that painting concrete to make it both decorative and protective is an easy and affordable task that most homeowners can complete on their own.

Painting concrete walls, indoors or out, requires the proper supplies and careful planning to produce a good result. It is imperative to completely clean the surface to get rid of any dirt, dust, or debris before beginning the painting process. This guarantees a smoother finish and improved paint adhesion.

It’s crucial to fix any cracks or other flaws in the concrete after cleaning the surface. Patch up any damaged areas with an appropriate filler and let it dry completely before painting. In addition to helping to create a uniform surface, this step keeps moisture from penetrating the concrete.

Selecting the proper paint type is essential for durable results. Choose a paint that is intended for outdoor use for concrete walls to ensure durability and resistance to weathering. Either latex or oil-based paint can be used indoors, depending on your taste and the particular needs of the area.

For a finish to look professional, correct paint application is essential. To prevent drips and streaks, apply the paint evenly using a high-quality paintbrush or roller and work in small sections. For optimal adhesion and coverage, it is usually better to apply multiple thin coats rather than one thick one.

Lastly, give the paint time to fully dry in between coats and before subjecting the painted surface to adverse weather or heavy traffic. This guarantees that the paint dries correctly and offers the highest level of durability and protection. Applying and prepping paint to concrete walls correctly can make this an enjoyable do-it-yourself project that improves the look and longevity of your room.
