When the coating is completely dry, it is 100% safe and can even be used in children's rooms.

How to remove paint?

Removing material from a metal surface

To remove MA-15 paint, review the specifications. Removing the old layer is a labor-intensive process, and there are several methods to choose from:

• Mechanical.
• Chemical.
• Sandblasting.
• Thermal.
• Hydrojet.

Let's consider other methods.

Removing paint from linoleum surface

It is worth paying attention to the composition, and if it contains drying oil, you should follow the instructions. Soak a rag in the solution and wipe the stain, and pour sunflower oil into the residue. After this, the linoleum should be wiped with soapy water, and there is also another method. To do this, you should soak gauze or a sponge in a solvent (white spirit, acetone). Wipe the stain until it disappears completely. Please note that the small piece of linoleum is exposed to solvent. Certain specimens may be severely damaged by the solvent.

Removing paint from clothes

You should take into account that fresh stains are much easier to remove than old ones. It can be removed with standard laundry soap. The item should be turned inside out and the stain should be placed under running warm water. Lather it with laundry soap and leave for 15 minutes. Use every solvent available. Wet the stain only on the wrong side, and place a towel and napkin between the layers of fabric. Paint when removing a way to imprint.

Material characteristics

The technical characteristics of this material are in the description of its properties specified in the certificate of conformity and the batch passport. Main parameters:

• surface – flat, smooth, without pockmarks or craters, without defects;
• the share of dry residue in the composition is 12%, the share of film-forming substances is 26%;
• degree of grinding – 90 microns;
• viscosity according to the VZ-246 viscometer at a temperature of +20 degrees – 64–140 (depending on color);
• film coverage – 45–210 g/sq.m. m (depending on color);
• Drying time for one layer is 24 hours at a temperature of +20 degrees;
• film hardness according to TML – 0.05 cu;
• lightfastness of the coating – 2 hours;
• resistance to water at room temperature – 0.5 hours.

Conditions for applying CM

Oil paint MA-15 is applied to a carefully prepared base.

1. Dirt, grease stains, dust, remnants of the old paint coating, red rust stains, and peeled pieces of the base are removed from the surface to be painted.
2. Plaster or putty is applied to areas with defects: chips, dents, small cracks.
3. Before painting, it is recommended to coat the surface with a primer based on an alkyd composition to enhance the tenacity of the CM to the base. The first coating of wood with paint begins with its preliminary treatment with drying oil. Can be replaced with wood primer.
4. After treatment with preparatory compounds, the base dries before painting.
5. The CM is thoroughly mixed in the container.
6. The oil composition is checked for viscosity. The thick one is diluted with a solvent (turpentine, white spirit). You need to be careful with the dose of solvent. The greater its share, the worse the quality of paintwork materials.

As a painting tool, you can use a pneumatic spray gun, brush, or roller. The best temperature when applying MA-15 paint is 5-35°C. The dye itself should be at room temperature (20-26°C).

Features of application

Painting with MA-15 is carried out after preliminary surface preparation. It is cleaned from dirt, grease, stains, dust, remnants of old coating, scale and rust. Potholes and uneven areas must be filled with plaster. To enhance the adhesion strength, it is recommended to apply a primer (alkyd, glyphthalic). New wood should be pre-coated with drying oil or wood primer.

Only dry surfaces can be painted. The paint is mixed before application. If the viscosity is too high, add a solvent - turpentine, a special thinner for oil paints. Application methods: roller, brush, direct pneumatic spray. Air humidity during work is up to 80%, temperature from +5 to +35 degrees. After completion of work, the tools are washed with white spirit.

Consumption per layer

The consumption of 1 m2 of product significantly depends on the absorbency of the surface, the method of application, and the color of the material. Indicator - from 55 to 240 g/sq.m. m of surface. Metal bases require less material than wood bases.

Layer thickness

When measured, the thickness of one layer of MA-15 is 25–30 microns. The coating in two layers is 50–60 microns. It is recommended to apply two layers without primer, or one coat with preliminary priming. The thickness of the layer depends on the preparation of the painters, the method of painting, and the viscosity of the product.

Surface drying

Typically, 24 hours of touch-drying at a temperature of +20 degrees is sufficient. But depending on weather conditions, temperature and humidity in the room, the period of complete drying can be 4–120 hours. The final properties of the material appear after 5 days from the moment of application.

Coating service life

If you meet all the requirements for surface preparation, paint and dry correctly, then a 2-layer coating will last for at least a year. We are talking about the complete preservation of its decorative properties when used in a temperate climate. Application temperature – from –45 to +60 degrees.

Painting schemes

For metal, the surface should first be primed with primers of the GF, VL, PF, FL brands. If there is rust, first apply a layer of Unicor or rust converter. Then apply 2 layers of MA-15 paint. Iron products without traces of rust can be painted in 2 layers without a primer, wooden ones treated with drying oil - in 1-2 layers.

Painting with oil paint

Painting with red lead

The metal surface to be painted must be properly cleaned of rust, scale, and grease deposits. It is recommended to use a rust modifier in the primer before painting. Wooden products must be sanded, sanded, degreased if necessary, and then treated with a compatible primer.

Before application, the paint is thoroughly mixed, adjusted to the desired condition with a solvent, and applied to the surface using a brush or roller in two layers with a 24-hour interval between operations. After painting, the tool is cleaned with white spirit, the brushes are wiped with a dry cloth and coated with vegetable oil.

Painting is carried out wearing rubber gloves and safety glasses. Enclosed spaces are provided with sufficient ventilation and air flow both during work and when the paintwork is drying. Since oil paints are flammable, fire safety precautions must be observed.

Drying speed

At a temperature of 20-25°C, the oil composition dries to degree 3 in 1 day. Drying speed is affected by 3 indicators: weather conditions, humidity and air temperature. The coating can be completely ready for use either after 4 hours or after 5 days. Its polymerization occurs 5 days after coating the base.
