Priming is a very important step in preparing any surface for painting. Moreover, sometimes this stage determines the quality of the result. The primer for plastic, like any other, plays an important role, it fills all the small depressions, cracks, scratches and levels the surface, as a result, it is possible to apply the finishing decorative coating without flaw. With it, you can ensure high adhesion of materials. If we compare this primer with others that are intended for metal, wood or drywall, then the first has the qualities of elasticity and is suitable for preparing soft surfaces for further painting.
As a rough base, you can use fiberglass, plastics, thermoplastics that cannot be painted with conventional enamels. This includes products such as car bumpers, spoilers, mirror housings, as well as moldings and dashboards. With the help of these soils, it is possible to process decorative fences, plastic furniture and pipes, as well asall kinds of decor items. Conventional primers and paints do not have elasticity, which is why they do not stick to plastic surfaces for a long time. You can buy special paint, but the price of such mixtures is much higher, and the color range is very scarce.
Main benefits of spray primer
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 resulting layer dries in just 15 minutes. It is characterized by increased elasticity, which is guaranteed by a high content of plasticizers. This creates the desired adhesion of top coats and paints to surfaces. The primer is translucent, it is almost colorless, which means it has a suitable base to cover any color. On the surface that has been treated with a primer, you can apply any paint, including those not intended for such work. Soil for plastic will be used in the volume of one cylinder per 2.5 m2. Such compounds are available, they can be purchased at any hardware store.
Features of using acrylic spray 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 sandpaper. This will make the surface rough. Nextthe step is to degrease the base with a solvent and a soft rag. 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 cylinder 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 an aerosol package 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 multi-colored strokes with a brush. Acrylic paints will perfectly lay down on the painted surface. In order for the drawing not to be erased, it should be fixed with an acrylic spray varnish.
Soil characteristics 6000 KUDO
If you have purchased the above plastic primer, you can use a 520ml can. This composition is intended to prepare for the application of paint on the external plastic surfaces of the car. With this mixture, it is possible to increase the adhesive strength, which is required for the adhesion of the base coat to the surface to be painted. The soil is flexible and hardens quickly. It is used on all kinds of plastics, and different enamels can be applied to its surface.
Mixon PlastoFix primer characteristics
This plastic primer is a clear, one-component, quick-drying, ready-to-use primer. The primer can improve the adhesion of heavily paintedplastics. It is important to familiarize yourself with the surfaces that are suitable for priming before using the composition, among them - plastic parts of car 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 described composition is not applied. If it is necessary to repair small areas, it is acceptable to use primer over the old paintwork.
What else you need to know about plastic primer
Spray 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, are durable, and also odorless. It should be remembered that acrylic primer for plastic is not a universal composition, since it cannot be used for processing metal and other materials.
Alkyd resins are substances that form the basis of universal primers. The latter are used for plastics as well as metals. They are durable and strong, but have a smell, and their use requires compliance with certain requirements. Acrylic primers are the most common lately, which are easier to apply and have a low cost. They are suitable for almost all types of work. Alkyd primers are more difficult to apply, but they can be used to treat bumpers withbuilt-in metal gratings and other products. In addition to the above ingredients, the primer 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
Kudo brand plastic primer has the ability to retain elasticity after drying, while preventing cracking of the coating, even if the product is used at low temperatures. Acrylic acts as the basis of this primer. Between layers it is necessary to maintain an interval of 10 minutes. Whereas drying to touch lasts 20 minutes. You will wait for complete drying in 2 hours. Ingredients include functional additives, polyolefin resins, dimethyl ether, butane, propane and xylene.
Feedback on the features of applying Kudo primer-enamel
Primer for plastic, reviews of which are recommended to read before purchasing products, should be applied to surfaces that have not been primed up to this point. In order to achieve the best 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 as an additional preparation, the Silicone Remover is used. Buyers emphasize that if the ambient temperature is kept within 20 ° C, then the timedrying of the surface will be twenty minutes. And in order to prevent clogging of the spray head, after completion of work, it is necessary to turn the can upside down and start spraying. This must be done until the composition stops flowing.
Conclusion
On sale you can find primer for plastic in cylinders for use with spray guns. These mixtures are intended primarily for professional use, as they can only be used with the help of special expensive equipment. But in terms of composition and characteristics, aerosol and balloon soils do not differ, with rare exceptions.
