Liquid plastic is used as a reliable, practical and dense sealant. It is a convenient tool for processing PVC (metal-plastic) window joints. The substance has a number of advantages, among which are high-quality connection, easy use and favorable price. After application, the joint is covered with a decorative layer using paint. It is necessary to find out about the characteristics of liquid plastic and paint suitable for decorating it in advance before purchasing the material.
What is it and how do I use it?
Liquid plastic (glue) is a modern means, a special polymer composition that has many uses. Repair professionals call liquid plastics a "lifesaver." Due to its convenient form, it can be used by a beginner, but it is necessary to carefully read the instructions for use and follow them clearly.
If an experienced master gets down to business, then there should be no problems and difficulties with the sealant.
Consumable material is able to quickly close gaps in PVC structures. It can also be used while working on wood or metal. The fluid and thick texture will fill up the empty space. The substance deservedly bears the title of universal putty.
Using a low quality compound
To avoid problems with the sealant, purchase products from well-known and proven brands. Experts recommend not to skimp on the product, otherwise you will not avoid such unpleasant consequences:
- discoloration of the seams;
Liquid plastic can be used for both outdoor and indoor work. Due to this characteristic, the material has a large field of application. The tool is used both for minor local repairs and during large-scale repairs.
The finishing material is most often used in the following types of work:
- the process of installing window structures, despite their complexity and originality;
- installation of slopes;
- protection of car parts from the destructive effects of corrosion;
- additional processing of the inner surface of the pool bowl;
- removal of rust particles from metal surfaces;
- strong connection of metal parts and spare parts (the material works in accordance with the principle of diffusion welding);
- elimination of defects such as cracks and gouges;
- sealing of seams;
- plumbing work.
Only the most basic uses are outlined here, in reality there are many more.
For painting on liquid plastic, polymer paint is used. This dye solution and putty have the same elements.
In this case, you always need to take into account the peculiarities of using polymer paint and take a serious approach to its choice.
A coloring composition of this type is a suspension of a pigment in a polymer solution. It is worth noting that most of all enamel on the market today are products consisting of a polymer (it can be organic or artificial) and a solvent. Additional elements are also added for color, elasticity and other performance characteristics.
The peculiarity of the paint is that the polymer does not dissolve in the composition, but is contained in it in the form of separate small particles (dispersion).
The main varieties of polymer-based paints
When making a choice in favor of this type of paint, it is necessary to understand the rich assortment of this product. Compositions can be:
The first option boasts excellent electrical insulating qualities, as well as increased resistance to physical and mechanical stress. In addition, the material is not afraid of chemical attack and pleases with high adhesion. Constant loads are also not a problem. Painted surfaces become resistant to liquids, alkalis, fuels and oils.
Coloring agent for external use
If you have used liquid plastics outside and are looking for a suitable paint for your coating, you need to know exactly what polymer compounds can be used in this area.
On the shelves in stores, you will find special coatings for treating objects and buildings located in the open air. The best choice is polyester paint… The material is recommended for the treatment of window openings and profiles, roofs, facades and verandas. Also, the composition is suitable for painting furniture and vehicle parts.
In addition, the paint shows increased resistance to various solvents, oils and water. Its decorative properties are also excellent. The decorative layer attracts attention with its brilliance, color saturation and expressiveness.
It is recommended to use the paint on parts subject to constant external influences: friction, stress, impact.
Composition for interior decoration
Epoxy and epoxy polyester paints are ideal for indoor use. Polymer epoxy compounds pleasantly surprise with excellent technical characteristics. After drying, it forms a strong and elastic film that is resistant to acids, chemicals and impacts. A quality product has high corrosion resistance. Disadvantage - the material acquires a yellow tint over time.
Epoxy-polyester compounds do not fade after use. The paint forms a dense, hard and at the same time flexible coating. Powder paints of this type are great for finishing metal coated items: refrigerators, washing machines and other household appliances.
Advantages of polymer paints:
- Long service life. Over the years, the paint will retain its color saturation and attractiveness.
- Wear resistance. A high-quality composition is not afraid of negative external influences, while maintaining operational characteristics.
- The paint dries quickly.
- Economical material consumption.
- Huge variety of colors. Hues differ in saturation and brightness.
- Safety in use due to environmentally friendly components.
- Simple operation.
- Universal use. The paint is suitable for working with various surfaces: glass, plastic, concrete, wood, metal, polymer clay, ceramics.
The main characteristics of polymer paints include the following features:
- It takes about an hour to dry one layer. The time depends on the thickness of the layer and the conditions under which the painting was carried out.
- The standard consumption of the substance per square meter is more than 200 grams (if you use a special pneumatic spray).
- Stability of the film under static action of liquid is a little less than two days at temperature conditions of +20 degrees Celsius.
- The part of non-volatile components in the paint is less than 23%. The paint can be thinned if necessary.
Surface preparation and painting
Before applying the paint, the substrate must be properly prepared:
- First you need to clean and degrease the surface. To do this, you can use acetone, various solvents or gasoline.Carry out this procedure carefully so as not to damage the painted surface.
- The paint should be applied carefully using special tools: brushes, rollers or a spray gun.
- If you intend to paint with epoxy polymer paints, then it is recommended to arrange a layer with a thickness of 0.5 millimeters. Such a layer will retain its density, practicality and resistance to shock, stress and mechanical damage.
- Be sure to read the instructions for use of the coloring composition before use, calculate the material consumption and surface dimensions.
- To get an even edge after staining, use masking tape. With it, you can easily create a clear border.
How to remove the coloring composition
If it is necessary to remove the old layer of polymer paint, follow these instructions:
- For quick and effective disposal, use solvents specially formulated for polymer paint.
- The optimal temperature conditions for the procedure are from 8 to 25 degrees Celsius above zero.
- The liquid for removing the old layer must be carefully applied, evenly distributed. We leave the composition until cracks form on the surface. Estimated time is 3 to 15 minutes.
- Never allow the solvent composition to dry on the painted surface.
