Polymer paint for concrete: main types and manufacturers, application technology on concrete floors

For concrete floors, polymer paint is a flexible and long-lasting solution that provides both aesthetic appeal and protection. Knowing the various kinds of polymer paints that are available is crucial for people looking to improve the appearance and durability of their concrete surfaces, whether they are businesses or homeowners.

Polymer paints are made by a variety of producers, and each has special qualities designed to meet particular requirements. These paints, which come in epoxy and polyurethane varieties, offer resistance to abrasion, chemicals, and environmental elements, making them perfect for both indoor and outdoor applications.

In order to achieve a smooth and durable finish, polymer paint application on concrete floors requires multiple steps. For best results, prepare the surface properly, select the appropriate paint type, and adhere to the application instructions. Whether you’re working on a commercial renovation or a home improvement project, knowing the right application technique can make your concrete floors look good and last a long time.

Why paint concrete surfaces

High-quality composition and adherence to all building codes and regulations result in a concrete floor with excellent technical and operational qualities. However, because hardened cement laitance is fragile, chips and cracks may occur on the top layer of the base during use, causing cement dust to be released.

Tiny dust particles that enter the body through the respiratory system can cause allergic reactions, skin and mucous membrane lesions, and respiratory illnesses. Cold concrete can aggravate pre-existing medical conditions and lead to the onset of colds. Assembly and equipment part clogging caused by cement dust causes rapid equipment wear and performance loss.

Grinding and then painting the surface is necessary to get rid of issues with continuous dust release.

Paint the floor and ensure that any chemicals, such as gasoline, electrolyte, oil emulsions, and solvents, that may leak from machinery and other equipment do not damage the coating. The top layer of the concrete surface becomes damaged and cracked when floor-mounted intra-shop transport vehicles like loaders, rigging trolleys, and electric cars are used frequently in the production area.

To enhance the appearance, paint is applied to the walls, ceiling, and concrete floor. The final layer becomes clear, silky, and has shielding qualities.

Types of polymer paints

Film-forming polymers and other ingredients that influence adhesion, flowability, and spreading are included in the powdered composition of polymer paint material.

Concrete can be painted with the following paints:

1. Polyurethane.
2. Epoxy.
3. Acrylic.

Polyurethane coatings

Painters use polyurethane compounds to coat workshops and production areas because the treated coating is resistant to mechanical impacts, solvents, and petroleum products, as well as the harsh effects of low temperatures. Depending on the paint’s characteristics, the floor becomes robust, smooth, glossy, or matte after it hardens and may have inclusions of minerals.

It is advised to paint the surface twice after priming it first for durability. For the first layer, 200–400 g/m² are consumed.

Interior residential buildings do not use polyurethane. It smells strongly and can’t be applied if the concrete coating’s humidity level is higher than 5%.

Epoxy resin based paint

The most common application of epoxy paint is on concrete bases in public spaces such as kindergartens, schools, and hospitals.

It takes the place of primer and is non-toxic, safe, and affordable. The compositions perform well in terms of service life, resistance to moisture, and resistance to frost outside.

Before using, two-component epoxy paint needs to be thoroughly mixed. Two coats of the product are applied, separated by at least eighteen hours to allow for drying. Consumption on average is 200–300 g/m².

Acrylic

Because of its many benefits, water-based acrylic paint is used for painting both indoor and outdoor surfaces. Monuments, fences, and concrete walls are covered with it. Concrete is shielded from moisture, dust, and corrosion by acrylic, which is odorless and impervious to chemicals.

A spray gun can be used for painting. Dusting and cleaning is sufficient; no prior priming is required. One square meter of paint requires 300–500 g of paint.

Tools and equipment for applying paints

In order to paint concrete with polymer paint, you’ll need:

1. Paint brushes.
2. Rollers.
3. Spray gun.
4. Drill for mixing or mixer.
5. Tray or grid for collecting residues.
6. Squeegee.
7. Sliding telescopic handles.

1. Acrylic primer. Consumption – 200-300 g / m².
2. Liquid polymer impregnations. Average consumption – 200-350 g / m².
3. One-component polyurethane soil. 200-250 g of material is consumed per 1 m².
4. Epoxy primer-impregnation. Average consumption for concrete is 350-700 g / m².

1. Steel dust shields.
2. Grinding discs for mechanical processing.
3. Sandpaper.
4. Rags.
5. Spatula.
6. High-pressure washing device.
7. Sandblasting machine (if possible).
8. Industrial vacuum cleaner (if necessary).

1. Workwear.
2. Safety shoes.
3. Work gloves.
4. Protective mask.

Safety precautions

Because of its toxic and rapidly igniting components, workers handling powder processing must take the following safety precautions:

1. Degreasing is carried out with aqueous solutions; the use of solvents is avoided. To. they are capable of increasing the explosion hazard class to level B-Ia.
2. When spraying, use improved types of sprayers that have protection against spark breakdown to grounding.
3. Painting is carried out in an isolated room with a working supply and exhaust ventilation.
4. Paint is stored in fume hoods and in a separate specially equipped room. In such places, the installation of power cabinets, electric motors, electrical equipment, control panels and the presence of open wiring are prohibited.
5. Use protective equipment against possible effects of aggressive substances. It is recommended to treat hands with Vaseline or lanolin ointment. Rinse them with soapy water once every 2 hours.

Concrete polymer paints provide a strong and adaptable way to improve and preserve concrete surfaces. This article covers the primary varieties of polymer paints that are available, identifies the top producers, and describes the easy application procedure that guarantees a smooth and durable finish for a range of concrete surfaces.

Technology of painting floors with polymer paints

There are five steps in the polymer composition painting technique:

1. Preparation of the concrete surface for processing.
2. Priming.
3. Trial application.
4. Main technological process.
5. Drying.

Surface preparation

When the concrete base is ready to be painted, it needs to be smooth, dry, and defect-free. A visual examination of the floor is done first.

In the event that it has cracks and crevices, they are opened and fixed. Special solutions and sealants are poured into the seams.

After that, debris and foreign inclusions are removed from the surface using sandblasting or grinding discs. Using a steel brush or vacuum cleaner, molding oil, or high-pressure water washing, cement dust can be eliminated.

In the event that a screed was applied, the concrete must dry out for 28 days. Wet sandblasting is applied to the glossy base to create a rough surface. It’s sanded the original floor.

Priming

To strengthen the polymer’s adhesive bond with concrete, priming the coating is advised. There are phases to the process. Impregnations are added first.

When applied under heavy loads, special compounds can stabilize, strengthen, and improve the concrete floor’s resistance to wear. Hardeners are applied to the base right away following surface preparation.

Applying the primer according to the composition type is the second step.

1. Mix the mixture thoroughly.
2. To create an anti-slip effect, add quartz sand in a ratio of 1:10.
3. Apply the mixture in 1 or 2 layers to a degreased, dried, clean surface with a roller, paint brush or spray gun.
4. Dry.

Test application

Paint a small area, one square meter, in test before moving on to the main process. Testing is required to ascertain the treatment’s quality, surfaces’ compatibility, and the material’s actual consumption.

The treated area is additionally exposed to loads and abrasion after drying. Paint the entire surface if the coating doesn’t chip or crumble.

Painting

Paint should be applied as follows:

1. Use a roller or spray gun.
2. Make strokes in different directions and rub on the floor.
3. In order for the paint to dry faster and look better, the product is applied in a thin layer.
4. To carry out the repeated procedure, wait for the previous layer to dry completely.
5. When painting corners, use masking tape, for baseboards and walls – narrow brushes.
6. Dry the coating for 3 days. If the paint is applied to freshly poured concrete, the drying time increases. The polymerization is finally completed on the 7th day.
