The main goal, which is trying to achieve when painting plastic - giving the material of a harmonious appearance in the interior of an apartment or building. Today, more than 2 thousand colors have been developed, which will help embody this desire to life. One task remains - to properly paint the PVC profile.
Paint for PVC
Unfortunately, plastic also yellows from time to time under the influence of the rays of the Sun, thereby losing its original appearance. Also "destroy" and its physical characteristics. Thus, the painting of the profile will help protect its surface from such detrimental manifestations.
Preparation of the surface to staining
Pray PVC do it yourself
Painting of the plastic profile by acrylic paints on the water base has certain advantages, among which you can allocate:
- Preparatory work is rapidly produced;
- The surface dries quickly at room temperatures;
- For 8-10 hours, the finish dials the strength at a temperature of only 20th;
- Coloring can be carried out both manually and automatic pulverizers;
- Paint has large decorative features (imitation of wood, pearl, metallic, etc.).
An important point before applying paints on the product is its preliminary preparation.
First of all, you must be sure that there is no dirt on the surface, silicone residues or mounting foam, fat traces and other garbage, which is a barrier of durable plastic adhesion with paints.
To carry out proper surface preparation, you can follow the following instructions:
- With the help of a napkin or compressed air, remove the crumb and garbage from the surface of the product;
- I am impregnate with specialized cleansing agents that are made precisely for polystyrene;
- Remove fat and other lubricating mixtures from the surface, thereby remove the static voltage;
- Give the surface for 10-15 minutes, so that the cleaner evaporated.
Following the advice of specialists, it is better to purchase a specialized activator cleaner for PVC, which, when applied, forms on the surface of micropores, which improve the adhesion of materials with each other.
Another way to increase adhesion is also known - plastic grinding and its subsequent primer. But this process is much more difficult and requires the master of certain skills and experience.

Mobile PVC pipes
First of all, it should be noted that if your plans do not include grinding and primer plastic surface, you should buy only that painting mass, which is designed specifically for painting PVC structures.
The most popular manufacturer of materials for plastic surfaces is the Rhenocoll trademark, its technical characteristics are shown below in the table.
| The residue of dry matter | 40-45% by weight |
| Density | 1,05-1.18 kg / l |
| Viscosity | 40-80 seconds |
| Consumption | 80-120 ml / m2 |
| Degree of brilliance | 30-60 cu |
| Diluent | Water |
| Hazard Class | Not dangerous |
| Resistance wet film | up to 160 microns |
To choose the most accurate material for coloring, you need to:
- Select a suitable shade from directories;
- Calculate that in which volume is required to be able to produce faithful calculations of the cost of materials in the future;
- Run pigment before reaching the desired color is not earlier than 1 hour before work.
Please note that before proceeding with the color of the surfaces, the paint is better filtering through any sieve with small holes.
Subtleties when painting surfaces
Choose paint for PVC
Painting plastic is better done by one layer at room temperature. Pre-apply primer compounds here is not required.
If you have the ability to work the pulverizer, thus the coating will be performed better. Also paints and varnish materials can be applied using brushes or rollers.
Dry staining materials about 8-10 hours, it all depends on temperature indicators. But it is possible to use painted plastic only after 3 days. If you need, the coating can be repeated, but only after the absolute drying of the first layer.
It is also worth paying attention to the fact that in any room there are many items that can cause a fire or suffer during fire. To avoid such a situation for coloring, it is better to buy fire retardant paint, which is a diluent of which is ordinary water.

How to dry the painted plastic profile?
Pray PVC alone
PVC paint products dries at temperature indicators that exceed the threshold in 40 ° C. Processed canvas need to be laid in a heated drying in 5-10 minutes. After painting.
If the air humidity is 65% and the temperature of 50 ° C, the wet film (with a thickness of 80-120 microns) will dry around 180 minutes. It is not necessary to immediately recognize the level of adhesion, having time, and complete polymerization is possible only after 5-7 days.
Remember that the product duration of the product may increase due to:
- a thick-sided layer;
- reduced temperature;
- large size treated area, etc.
As it became clear from the foregoing, the color of the plastic is not a tricky thing. The main thing is to carefully prepare the surface and remove all sorts of pollution. Only after that it is worth thinking about the color and the number of material.
