The technology of using paint for PVC windows
It happens that snow-white the owner of the house / apartment ceases to like the color of the window frames. indeed, windows made of plastic (that is, PVC, polyvinyl chloride) are put "forever", very very durable and strong, although after a while the appearance can change greatly.
There is a technology according to which painting of plastic windows may well be.
Everyone who has plastic windows should get acquainted with it. You will learn about paints for PVC windows.
Renovation in an apartment rarely affects PVC window frames. But sometimes it is necessary to paint the windows.
Here are the main situations in which this can happen:
Window coloring is not prohibited. But if it is possible to carry out work with the involvement of a specialist, you can update PVC profiles in other ways. Most often, colored structures are obtained by lamination - applying a special film to the plastic. After completion, the windows will acquire any desired shade, resistance to ultraviolet rays, water, temperatures, as well as household chemicals.
Still specialists can offer the following methods:
- Spraying enamel with polyurethane type.
- Coating with varnish.
Colored polyvinyl chloride is often carried out in production, but its color will be brown - like wood. The structure of such a polyvinyl chloride differs from the standard one that white profiles have. If it is impossible to apply professional methods to paint everything with your own hands.
PVC window paint is special composition, which must necessarily meet many requirements:
Only really strong paints can withstand negative impact.
Pay attention, how exactly should you paint profiles with such materials? The best paint for plastic windows, according to experts, is a special material for polyvinyl chloride.
But it is difficult to apply it by hand, and you also need to buy a spray gun. A suitable temperature level for application is about +18 degrees or higher, and this also imposes some restrictions.
It is recommended to paint window frames with one more means - acrylic varnish. It is easy to apply with a brush and once cured, the material will provide a matte, even surface.
Other possible types of paints:
Most liquid PVC paints are white, and they are also tinted to the desired shade. The most popular manufacturer of polyvinyl chloride products is the Feiko concern.
It produces high quality materials for painting plastic windows. The finished coating will turn out to be incredibly stable, durable, does not react to external influences, and also literally merges with the profile structure.
Still qualitative compositions can be considered as follows:
- Polusrul Enamel - they are not able to absorb dirt, washed by various means, and also have a large color palette.
- PaliPlast RР - the base material, the base for tinting, and any pigments and metallized pastes can be used, and also has excellent resistance to defect formation and dries quickly.
- Zowo-plast is an acrylic and water-based product that is easy to use, inexpensive and has an economical consumption.
What is needed to get the job done?
The attachments for the job may differ depending on the type paint and varnish material. For certain varnish materials, brushing is suitable, for others a spray gun is required. The second method is preferable, because the product will spray more evenly, and the speed of work is higher, as well as the quality. For manual painting, soft paint brushes are purchased according to the width of the profiles. For hard-to-reach places, a thin brush is needed.
To clean the protective film, foam, as well as other contaminants, you should buy a metal or plastic spatula.
Other tools and consumables for work are as follows:
You will also need the paint itself, and in certain cases, a finishing varnish and a primer.
When all recommendations are followed, everything must be clear, otherwise there is a risk of ruining the frame. Particularly important will be the high-quality preparation of the profiles, and only in this way the paint will lie flat and hold for a long time.
The dye will not adhere well to the glossy surface, and therefore its preparation is required without fail.
The service life of the coating will also largely depend on the preparation measures.
Here are the instructions for users on the use of polyurethane paint for PVC windows:
- The surface should be thoroughly cleaned and there should be no stains on it dirt, grease, dust and other things. Remove the remains of foam, glue, silicone, and then rinse off all cleaning and detergents from the profile several times with water. It will be possible to clean the surface ideally by using compressed air - so even the largest particles will be removed. If the film still remains on the profile (if the window frame is completely new), then it should also be completely removed.
- The edges of the glass should be covered with masking tape. The handles should be removed for the duration of the work.
- Saturate a cloth with a special solution to degrease the PVC. You can buy it in building markets, and this helps not only to reliably clean the base, but also to relieve static stress. Next, the solution should be allowed to evaporate, and then proceed to staining.
- Before painting, the surface should be primed (this will be written in the instructions). The primer should be applied in one layer using a pile with artificial pile. Even a primer for painting plastic parts for a car is suitable.
Also, in the role of preparation, the paint should be tinted, if necessary. Work should be carried out at least an hour before painting the windows, and the viscosity is monitored, and at an increased level, water should be added (if allowed by the instructions).
Be sure to filter out the paint before applying it to the plastic.
You can start applying the paint and varnish material from any angle, gradually move to the widest part of the window profile. Do not be afraid that stripes from the brush will remain on the surface of the plastic - if there is an excellent paint, they will quickly disappear. It is enough to apply one layer, and this is enough for high-quality painting of windows. But for major repairs with large defects, it should be painted in 2 layers, and the second should be applied no earlier than a day later, when the first layer dries out.
Instead of a brush, the best option would be to use a spray gun or spray gun.In advance, you should remove the glass from the frames, or securely glue them with paper, wide adhesive tape, paint film. Otherwise, they will be covered with paint.
Here are the parameters for spray painting:
Before starting work, wear a respirator, protective clothing.
The paint should be loaded into the gun. And make sure it is dry and clean beforehand. You should also adhere to a certain layer thickness (it turns out to be normative when the above parameters are met). This will allow the profiles to dry quickly and not lose their beauty. Usually for applying one layer with a spray gun, but for paints with a "metallic" effect, make two.
After final drying, a special transparent PVC varnish should be applied.
Peculiarities of staining
Co-extrusion technology is a unique method of staining. It is 100% reliable for obtaining a new PVC coating, and also allows you to make a variety of shades from an almost unlimited color range. Work should be carried out using acrylic varnish. This material provides an extraordinary surface - velvety to the touch, matte, very durable, not fading from the sun.
After staining in this technique, the structure is easy to clean; you can take care of it by any means, except for those that contain solvents. Acrylic varnishes have excellent wear resistance parameters, they do not appear defects. The environmental friendliness of the materials also leaves no doubt, and they are also harmless to people.
Recommendations for work are as follows:
- Despite the UV resistance, dark shades on the PVC profile should be additionally protected. To do this, use a special film that will prevent the paint from fading.
- Dark colors are capable of absorbing much more heat and may become hotter with use, which should be noted by users.
Drying windows after painting
Typically the resulting coating will set in a couple of minutes and dry within 60 minutes. Such conditions will be met at humidity up to 70%, and temperatures from +18 to +23 degrees. But use the windows with care within a week - so much is required for the paint to obtain its final properties.
Please note that it takes approximately 10 hours for the metallic paint to dry.
At the end of this time, the plastic is allowed with a protective film. Excessive paint thickness over the recommended thickness will result in longer drying times, sometimes up to 24 hours.
A special technique is used to quickly dry the colored polyvinyl chloride.With the help of special equipment, a temperature of about +55 degrees is obtained, while increasing it a little. The humidity level should not exceed 60%.
The paint will dry 1/2 hour faster, but the durability of the service is reduced with this technique. It is better to let the coating dry out by means of a natural path in order to enjoy the renewed plastic window for a long time.
