Priming is a very important step in preparing any surface for painting. Moreover, sometimes this stage determines the quality of the result. Soil for plastic, like any other, plays an important role, it fills all small indentations, cracks, scratches and evens the surface, as a result, it is possible to apply the finish decorative coating without a flaw. With its help it is possible to provide high adhesion of materials. If we compare this primer with others that are intended for metal, wood or drywall, the first has the properties of elasticity and is suitable for preparing soft surfaces for further staining.
As a rough base, you can use fiberglass, plastics, thermoplastics, which can not be painted with ordinary enamels. This includes products by the type of car bumpers, spoilers, mirror housings, as well as moldings and dashboards. Using these primers, you can process decorative fences, plastic furniture and pipes, as well as all kinds of decor items. Conventional primers and paints do not have elasticity, which is why they do not last long on plastic surfaces. You can purchase a special paint, but the price of such mixtures is much higher, and the color scheme is very poor.
The main advantages of aerosol soil
Primer for plastic (aerosol is very convenient to use) has many advantages. Thanks to the packaging, it is easy to apply to the surface, and the formed layer dries in only 15 minutes. It is characterized by increased elasticity, which is guaranteed by a high content of plasticizers. This creates the necessary adhesion of integumentary varnishes and paints to surfaces. The soil is translucent, it is almost colorless, which means it has a suitable base for covering any color. On the surface that has been primed, you can apply any paint, including not intended for such work. Soil for plastic will be consumed in the volume of one cylinder per 2.5 m 2 . Such compositions are available, they can be purchased at any hardware store.
Features of the use of acrylic aerosol primer
If you have plastic garden furniture that has long lost its white color, you can purchase plastic primer in a bottle to fix the pattern. The chair is cleaned with a brush and detergent, then the gloss should be removed using fine-grained emery paper. This will make the surface rough. The next step is to degrease the base with a solvent and soft rags. The surface of the furniture is primed from a distance of 25 cm. Before starting work, it is necessary to mix the contents of the container well, for this it should be shaken for 2 minutes. After 20 minutes it will be possible to proceed to the next stage of staining. Enamel in aerosol packaging is applied from a distance of 25 cm, during operation it is necessary to periodically mix the contents of the container. To create a decor, you can apply several colorful strokes with a brush. Acrylic paints will perfectly fall on the painted surface. In order for the picture not to be erased, it should be fixed with acrylic spray varnish.
Soil Characteristics 6000 KUDO
If you purchased the aforementioned primer for plastic, you can use a 520 ml bottle. This composition is intended to prepare for applying paint to the outer plastic surfaces of the car. Using this mixture, you can increase the adhesive strength, which is required for adhesion of the main coating with the painted surface. The soil is flexible and quickly hardens. It is used on all varieties of plastics, and various enamels can be applied to its surface.
Mixon PlastoFix Soil Characteristics
This primer for plastic is a transparent, one-component, quick-drying, adhesive composition that is completely ready for use. Soil can improve the adhesion of heavily painted plastics. It is important to familiarize yourself with the surfaces that are suitable for priming before using the composition, among them are the plastic parts of automobile bodies, with the exception of polypropylene and polyethylene. This primer is recommended for polyurethane soft parts. If the plastic part or surface is already primed, then the application of the described composition is not performed. If it is necessary to repair small areas, the use of soil on the old paintwork is acceptable.
What else you need to know about plastic primer
The aerosol primer has high adhesion and elasticity, these characteristics are characteristic of polyacrylates, as well as alkyd resins. The former are used for the manufacture of acrylic primers, which are well applied to the surface, characterized by durability, as well as the absence of smell. It should be remembered that acrylic primer for plastic is not a universal composition, since it can not be used for processing metal and other materials.
Alkyd resins are substances that form the basis of universal soils. The latter are used for plastics as well as metals. They are durable and strong, but have a smell, and their application requires the observance of certain requirements. The most common in recent years are acrylic primers, which are easier to apply and have a low cost. They are suitable for almost all types of work. Alkyd soils are more difficult to apply, but they can be used to treat bumpers with built-in metal grilles and other products. In addition to the above ingredients, the soil in the aerosol contains all kinds of additives, namely dyes, modifiers and other compounds that are designed to improve the quality of the coating.
Characteristics of primer-enamel for plastic Kudo
The primer-enamel for Kudo plastic has the ability to maintain elasticity after drying, thus eliminating cracking of the coating, even if the product is operated at low temperatures. Acrylic acts as the basis of this soil. Between layers it is necessary to maintain a gap of 10 minutes. While drying on the stick lasts 20 minutes. You will wait for full drying after 2 hours. Among the ingredients, functional additives, polyolefin resins, dimethyl ether, butane, propane and xylene should be highlighted.
Reviews on the features of applying Kudo primer-enamel
Primer for plastic, reviews of which are recommended to be read before purchasing products, must be applied to surfaces that have not been primed before this point. In order to achieve better results, it is recommended to use the composition at a temperature not lower than +10 ° C. According to users, before surface treatment, it must be degreased, cleaned and dried, and “Silicone Remover” is used as an additional preparation. Buyers emphasize that if the ambient temperature is kept within 20 ° C, then the drying time of the surface will be twenty minutes. And in order to eliminate clogging of the spray head, after completion of work, it is necessary to turn the cylinder upside down and start spraying. This must be done until the composition ceases to act.
Conclusion
On sale you can find plastic primers in cylinders for use with spray guns. These mixtures are intended primarily for professional use, as they can be used exclusively with the help of special expensive equipment. But the composition and characteristics of aerosol and balloon soils do not differ, with rare exceptions.
