Paint for cement: production and application

Painting cement surfaces can significantly improve their durability and appearance. The correct paint can turn gray, drab cement into a vibrant, weather-resistant layer that looks great on a patio, basement floor, or concrete wall.

However, when it comes to cement, not all paints are made equal. Paints that are specially formulated are needed to properly adhere to this rough, porous surface. These paints are made to resist the problems that cement presents, such as moisture, variations in temperature, and severe wear.

Knowing the various cement paint kinds, how they are made, and how to apply them properly can make all the difference in getting a finish that lasts. These essential details will assist both professionals and do-it-yourself enthusiasts in selecting the appropriate product and applying it correctly for optimal results.

We paint cement cheaply and efficiently

Paint on cement plaster guarantees finishing dependability and durability.

Is there a paint for cement floors that is universal, long-lasting, and reasonably priced? Indeed, there are numerous types of coatings available, but the one you’ll make with your own hands is the most cost-effective.

It goes without saying that cement itself can demonstrate the best adhesion to a wall or floor plaster. So why not create your own paint using this substance?

Making a paint composition

One dye used in construction is carbon black.

Portland cement, pigments, and integrated fillers are the main ingredients in cement paint compositions; these additives determine the coating’s strength, hydrophobicity, and degree of hardening.

Making a straightforward composition at home is not hard.

We carry it out as follows:

• Pour distilled water into a plastic container (if you don"t have distilled water, you can use rainwater).
• Continuously stirring the water with a paintbrush, add cement in small portions.
• After the solution has acquired the consistency of liquid sour cream, add a suitable colorant (the best option is a colorant for mixing in water-based paints).
• Next, stir the solution until it acquires a uniform color.
• If the paint on cement is made for future use, it is advisable to use a bucket and a drill with a special attachment for mixing. The dosage in this case is 2 kg of Portland cement per 10 liters of water.

Important: The cement base precipitates if the finished paint is stored for longer than an hour. Because of this, the composition needs to be thoroughly mixed once more before being used. You can also add tiny amounts of water to the mixture as it thickens. Since the solution’s duration is usually only three to four hours, you should plan a composition that you can finish in that amount of time.

Painting technology

Using cement paints rather than conventional plasters

Painting wall plaster or cement floors is done in two steps:

• Apply the first liquid layer with a wide brush. Try to rub the composition into the surface being treated as much as possible.
• A day after applying the first layer, prepare the tinted solution again, but a little thicker than the first time. Apply this layer with a velor roller. To compensate for defects in the plaster of the walls, you can use a textured roller.

A spray gun can be used to apply paint on large surfaces, which will expedite the process and improve the quality of the final product.

Important: It is best to wet the surface with water an hour before painting in order to prevent the paint from drying out before applying the solution. Furthermore, for a full day following painting, make sure the drying surface is not exposed to direct sunlight.

It is worth noting that the DIY solution can be applied to metal structures and offers corrosion protection comparable to that of Zinga conductive paint.

After first moistening the metal structures, the composition is applied, ensuring the required adhesion. Painting metal in the sun is not advised because the iron heats up and the cement layer will dry out and crack.

Although homemade cement paint costs pennies, with proper application, it will last for approximately ten years.

Polymer cement compositions of factory production

Application of polymer cement impregnation on a concrete coating is shown in the picture.

Apart from self-made coatings, factory-produced polymer cement paint that satisfies GOST 19179-73 standards is available on the market.

The following ingredients are included in the paint’s composition:

• Portland cement;
• ground lime;
• emulsion of synthetic polyvinyl acetate resins;
• pigments;
• sand or ground limestone;
• asbestos dust.

These coatings have high adhesion to the concrete surface, short drying times, elasticity, and resistance to adverse environmental effects.

The color palette of factory-produced polymer cement paint is rather small:

• white;
• yellow;
• light yellow;
• terracotta;
• beige-pink;
• light green,
• gray;
• light blue.

Packaging for these compositions comes in two packs. A pigmented emulsion is contained in one package, and a dry cement mixture with fillers is contained in the other. All ingredients are combined and dissolved in water right there on the spot, following the manufacturer’s directions.

For external painting of concrete, brick, metal, and wooden structures, ready-made paint is utilized to improve the treated surfaces’ durability and aesthetic appeal.

Important: Because polymer cement compositions have a strong resistance to critical temperature values, they can also be applied to metal surfaces as fire-retardant paints.

At least 20 degrees Celsius should be the ambient temperature when applying the composition. It takes two hours to dry.

Selection of pigments for tinting cement

A range of pigments are available for use in coloring cement mortar.

The following kinds of colorants are in charge of providing the desired color in paints made in large quantities that contain cement:

• titanium dioxide – white;
• red iron oxide – red;
• yellow iron oxide – yellow;
• green chromium oxide – green;
• black iron oxide – black.

You can create a wide variety of color solutions by combining the aforementioned pigments.

The industrial paint used in cement mortar needs to fulfill the following specifications:

• be resistant to fading;
• do not dissolve in water;
• be resistant to alkaline and acidic environments.

Cement paint is designed to stick to uneven, porous surfaces and leave a smooth, protective coat behind. This article examines the process of making cement paint, emphasizing the special components that give it strength and resistance to the elements. It also includes useful advice on how to apply cement paint, which guarantees a smooth, durable layer that improves the look and durability of concrete buildings. Knowing the proper paint and techniques can make all the difference when painting an indoor or outdoor wall.

For cement surfaces, selecting the appropriate paint is crucial for both longevity and aesthetics. You can choose the paint type that best fits your needs by being aware of the various varieties that are available. Paints that are specifically designed to adhere well and withstand environmental factors like moisture, UV rays, and temperature changes are very beneficial for cement surfaces, whether they are used indoors or outdoors.

Materials engineered to form a strong bond with the porous properties of cement are used in the production of cement paint. This guarantees a durable finish that is resistant to peeling and cracking. Additives that increase flexibility are frequently found in high-quality cement paints, enabling them to move with the cement as it expands and contracts over time.

Use is just as significant. Cleaning and priming surfaces appropriately lays the groundwork for a successful paint job. Applying the proper methods and equipment, like rollers or sprayers, can also have a big impact on getting a uniform, smooth coat.

You can prolong the life of your cement surfaces in addition to improving their appearance by choosing the appropriate paint and applying it carefully. The correct cement paint can provide years of protection and beauty, whether you’re working on a small home project or a large commercial space.
