To do this, you need a special paint for PVC, which will firmly adhere to the smooth surface of the processed material.

Primary requirements
The main requirement that such a paint must meet is high adhesion. Unlike wood, plastic has a smooth slippery surface and a very solid, dense structure that does not give a high level of adhesion between materials.
Also, the coloring composition should have the following characteristics:
- water resistance;
- strength;
- resistance to mechanical stress;
- resistance to UV rays;
- preservation of color throughout the entire life cycle;
- the absence of toxic and poisonous substances in the composition that can be released when heated;
- resistance to temperature differences;
- long service life;
- extensive color scheme;
- the ability to give the object a specific texture.
The ease of applying the composition also plays an important role, since often plastic windows are painted with their own hands.

All these qualities have a polyurethane-acrylic water-based paint for PVC. It is characterized by uniformity of coating, resistance to defect formation, high drying rate, and allows tinting on its own. With its help, you can create textured effects by introducing special additives into the base composition.
The wide color spectrum of such paint totals more than 2000 shades. In addition to traditional tones, among them are:
- nacre;
- metallic;
- composition with the addition of sparkles.
In this case, painting the PVC profile will add originality and uniqueness to the room or building facade.
to contents ↑Preparatory work
Before how to paint a windowsill, windows, doors or other surface with your own hands, it should be carefully prepared. To do this, you must:
- Remove mosquito nets, blinds, curtains, ebbs and other objects that will interfere with the work.
- Free the surface from mechanical impurities.
- Remove greasy stains.
- Seal rubber seals and other accessories with construction tape to prevent paint from entering.
- Glass should be closed with plastic wrap.
For more effective cleaning, degreasing and removal of static voltage, you can use specialized cleaner-activators for PVC. They are applied to a tissue towel, which wipes the treated surface. After this, it is necessary to allow the solution to completely evaporate, which takes 5 to 10 minutes, and only after that proceed with painting.
If the surface has roughness, scratches and other irregularities, they must be puttied, and then sanded with fine sandpaper. Finally, cover the entire surface with an even layer of primer. If you have certain skills, you can do it yourself. But if there is no experience, then it is better to resort to the services of professionals.
to contents ↑Application technology
Windows and other PVC products are painted with a spray gun. Before pouring polyurethane-acrylic paint into it, it is necessary to add a suitable color to it and mix thoroughly.
After opening the can on the surface of the coloring composition, you can sometimes find a film that must be removed. Its composition contains solid particles that do not dissolve with stirring and clog the nozzle of the spray gun.
If the paint has undergone freezing, then it should be discarded, because after exposure to freezing temperatures it loses its properties.
For coloring, it is better to choose dry, but not very hot weather. Do not work at temperatures below +5.
Paint for windows is applied with a thin uniform layer with a thickness of 80 to 120 microns. In this case, there is no need to pre-paint corners, faces and hard-to-reach areas. The composition adheres well and does not drain from vertical surfaces. The paint begins to stick tightly to the surface after 2-3 hours. But its complete drying lasts another two days.
In industrial conditions, forced drying is used for two hours at a temperature of plus 50.
to contents ↑Aerosols
To paint a small surface of PVC, you can use paint in an aerosol can. This container is convenient in that it reliably protects the contents from air, therefore, prevents the formation of a film on its surface.
Other benefits of this paint include:
- convenience in transportation;
- the possibility of coloring hard-to-reach spots and small parts;
- lack of need to use additional tools;
- increased adhesion.
Most often, spray paint is used when painting PVC parts in car interiors.
Uniform application of paint requires certain skills and experience, so it’s worth a little practice before proceeding with the staining procedure.
to contents ↑Coating protection
Despite the fact that acrylic paints adhere well to the surface of PVC products, they can be further protected with a glossy varnish for plastic with a water base. In addition to protective, it also performs a decorative function, giving the product shine.
This material can be used to process painted plastic window sills and windows in kitchens where they are exposed to aggressive factors.
Varnish is applied with a brush and does not require certain skills. Therefore, these works are easy to do with your own hands.

Important points
When purchasing paint for processing plastic windows, you must first calculate the required amount of material. To do this, measure the surface that will be processed. The exact calculation will be done by sales consultants.
The cost of polyurethane-acrylic coloring composition is quite high. However, the low material consumption and long service life without additional treatments fully justifies the cost.
When applying paint, the most important factor is accurate adherence to the instructions. High environmental safety indicators of the presented PVC inks make it possible to use them in residential premises, children's and medical institutions, catering facilities.
when my husband and I decided to paint the PVC windows, slopes and window sills, shoveled the entire Internet))) as a result of the reviews we chose Enamer paint, and in the spray can, which seems to be more convenient because it needs to be sprayed with paint in any case. We did everything according to the instructions and the next day we already had perfect updated windows of a beautiful gray color)))
We needed to repaint the plastic windows in order to create a finished design at home: so that the white color did not stand out too much. Only “Enamer” picked a good option for color, now a single whole picture, pleasing to the eye)
