How and with what to paint PVC windows with your own hands at home

PVC profile windows are painted with paint of the selected shade if the frame material needs to be repaired or replaced. In addition, the painting of window frames often meets design requirements, where the main task of changes is the combination of shades. When choosing a paint and varnish material, it is important to find a composition that adapts well to the surface and provides strong adhesion.

When to repaint PVC

Over time, the appearance of the material from which the plastic window is made wears out. At the same time, the PVC profile remains strong and frost-resistant. Reasons why it is recommended to paint plastic window surfaces:

• the plastic coating has taken on a greyish hue;
• yellow stains appeared in some areas of the windows;
• microcracks or scratches have formed on the window sill;
• the interior of the room requires replacing the white plastic on the windows;
• it was necessary to make the windows in the house unusual and unique.

Professional technicians paint plastic surfaces using lamination. For this, a special lamination film is applied to the plastic surfaces. You can paint plastic windows yourself with acrylic enamels.

Information! Professional painting of a plastic window most often involves the use of a film imitating the surface of a tree. Applying a dark laminate gives the plastic structure the appearance of a wooden surface.

Requirements for coloring compositions

For painting PVC profiles, compositions that meet certain requirements are used:

1. Persistence. This indicator means that the paint with which the profiles are covered must be resistant to rain, snowfall and wind. The outer side should not fade under the influence of sunlight, so that there is no contrast with the part located inside the room.
2. Viscosity. The optimum viscosity for painting a plastic surface is considered such a quality of the composition when the paint lays down in an even layer, does not form spots and does not accumulate in lumps.
3. Fast drying. The paint should dry in a short time so that no dirt adheres inside the topcoat.
4. Respect the environment. The absence of toxins in the composition is an important indicator when choosing a composition. The main part of the coloring pigment will be on interior surfaces, so it should not be hazardous to human health.

Which paint is right

PVC windows are painted in any chosen shade, which will lie on the surface in an even layer. The dark brown color makes the window frames look like wooden profiles. Compounds that can be used to paint PVC profiles should provide a matte surface.

Car enamels are tinted with any chosen paste.By mixing colors, it is possible to achieve the formation of a silver or golden tint.

Preparatory work before painting

Before you start painting, you must prepare the fixtures and the necessary tools:

• brushes or pots for applying paint;
• plastic and metal spatulas;
• alcohol-based solvent;
• protective equipment (respirator, goggles, gloves, apron);
• a special container for paint.

The preparation of the windows is an important stage of the work. Films, small debris and remnants of construction foam are removed from the surface of the plastic. Microparticles are removed using special equipment based on compressed air treatment. After the complete removal of debris, the panes are washed with a detergent and additionally treated with a degreaser. This technique ensures a good grip.

For profiles covered with scratches, chips or cracks, an additional primer is recommended. A plastic primer helps improve the material's appearance, provide adhesion, and protect against moisture and mildew. For plastic profiles, a directional-type liquid primer is used. The primer is allowed to dry completely for 24 hours before painting.

Home coloring procedure

Windows are sealed with foil, fixed with adhesive tape. The fittings are unscrewed and removed beforehand. They start painting only when all surfaces are completely dry after treatment.

The procedure for tinting windows:

1. The paint is applied by directing the brush from one of the corners to the center of the frame. If a spray bottle is used, hold it 25 to 30 centimeters away at a 45 degree angle.
2. The surface is painted from top to bottom from the outside.
3. Then the inner surface is painted, provided that the window is tightly closed. This will prevent paint from getting on the rubber bands inside the window frame.

The paint is applied with a brush in two layers, spraying is done in one dense layer. Metallic paint, belonging to the category of aerosols, car enamels, is applied in 2 layers.

Acrylic glazes provide good adhesion. After drying, it is recommended to apply varnishes to fix the result and create a finishing gloss. For this, special water-based varnishes are used, which are suitable for application on plastic. Varnishes perform a protective function, and also extend the life of the coating.

Information! For work, it is recommended to select brushes that are suitable in width for the width of the main profile.

Drying

It takes a little time to dry the windows, but it should be remembered that the final polymerization of the coloring compositions ends in 3-5 days. Setting of automotive enamels or powder coats begins 10 to 15 minutes after application. The thinner the coat, the faster the finish dries. Appropriate conditions for rapid polymerization:

1. Humidity level. The optimum moisture content for drying paint on a PVC profile is 65%.
2. Temperature conditions. The surface quickly polymerizes at temperatures from +18 to +23 degrees.

Drying can be accelerated by using a hair dryer or heat gun. Devices help to raise the exposure temperature to +50 degrees.This technique shortens the drying time by 15 to 30 minutes.

Solve common problems

When self-painting windows, typical problems often arise. To avoid errors, it is recommended to follow certain rules:

• ready-made compositions are chosen for work, in which you do not need to add pigments or carry out independent coloring;
• when calculating the amount of paint, the entire area of ​​the window frames is taken as the basis for the calculation, another 200 milliliters are added to this amount;
• Proper surface preparation is important when painting plastic frames;
• before starting work, it is recommended to test brushes and guns on small surfaces.

Builders recommend painting windows with a spray gun. The spray coating mechanism helps create a thin, even layer of rich shade.

After drying, the following types of defects may appear on the coating:

1. Stains are visible on the surface, dust has adhered. To avoid this defect, it is necessary to use compressed air window cleaners. Blowing will clean the surface of micro dust particles.
2. Fisheye or glare. A defect occurs if the surface has not been sufficiently degreased. The error is eliminated by wiping, further work with a degreaser.
3. Grooves. On the surface after staining, scratches that are not noticeable on the white profile often appear. To eliminate the defect, use grinding, then paint the surface again.
4. Shagreen or bubbling. This defect appears when a thick layer of paint is applied to the profile.Shagreen is quite difficult to remove, this error requires cleaning the surface, putty and repainting.

Sometimes self-painting can stain areas that need to be kept clean. To quickly remove the paint, you need to prepare a solvent and a cloth in advance, with which you can quickly wipe off the stains.
