Paint roller: types and features of application

In the arsenal of each builder or a master for finishing operations, tools for painting works are provided for sure . The design of traditional rollers is still in demand despite the dominance of more technologically advanced painting machines. With the help of a maneuverable manual assistant, the wizard can perform operations in complex areas, as well as timely correct mistakes made during the execution of paint operations. At the same time, it can not be said that the paint roller does not improve at all. Of course, the elementary device of this instrument remains its main advantage, due to which high ergonomics is achieved. Nevertheless, the market offers a wide range of roller models, which differ in shape, size and materials of manufacture.

General arrangement of platens for painting works

The basis of the design of almost all versions is represented by a handle with a plastic handle. From it departs a metal rod on which the working part of the tool is fixed - a cylinder with a fur coat. There are many types of materials that are used in making this nozzle. Depending on the purpose, the paint tool can also provide for additional tools that extend its functionality. It is important to note that the convenience in the process of work to a large extent depends on the characteristics of a particular device. For example, a coating of several types of paintwork should be carried out by different rollers, because any contact between foreign solutions and emulsions is able to spoil the result of painting.

Dimensions of rollers

In assessing the size, attention should be paid to three main values. First of all, this is the length of the pile. This parameter determines how effectively the coat will absorb and give off the paint or other composition. For example, the roller is a paint roller, the length of the pile varies from 10 to 12 mm, it can be used in the coating of smooth surfaces with a finishing paint layer. Models with this parameter of 15-20 mm are recommended already for working with rough and problem surfaces. Usually in such cases, protective and dispersion formulations are used.

The next characteristic, which should be paid attention, is the thickness of the handle connecting the handle and the cylinder. It depends on the convenience of the work. In the standard, this value varies from 6 to 8 mm. For example, paint rollers Stayer in the Dualon series are supplied with rollers with a handle thickness of 8 mm and a cylinder diameter of 30-48 mm. And one more important parameter is the width of the roller, which on average is 20-25 cm.

Classification of rollers by materials

When making fur coats for rollers use different materials, among which the most popular are the following:

• Polyamide. This fiber is of artificial origin, which has good retention properties. With the help of a fur coat from this material, it is possible to realize an optimum distribution of the paint on the working surface with the provision of high chemical resistance.
• Foam. In its origin refers to polyurethanes. To the advantages that a foam roller has, it is necessary to attribute elasticity and rapid recovery of the mold. It should also be taken into account that this material does not combine well with aggressive chemical components, but provided a suitable choice of paint provides a uniform coating without bubbles.
• Velours. This coat is provided with a fabric base with pile based on polyamide fibers. This option is good because it does not roll down, and does not spray the mass for application. It is recommended to be used for the final painting of smooth areas.
• Natural fur. In the manufacture of fur coats, sheepskin is usually used, which has excellent absorbency and the ability to efficiently distribute the composition over the working surface. Use a fur roller can be on any surface, performing the application of oil paints, enamels and varnishes. However, it is better not to combine calcareous solutions with such a roller, since the fur is destroyed from contact with lime.

Classification by type of fastening of a fur coat

There are three ways to fix the fur coat to the base of the tool - models with glued and hot-melt fixing, as well as modifications with attachments of the replaceable type. In the first case, fixation is achieved by elementary gluing the base with the fibers to the core. Usually, a foam roller is manufactured in this way, which is not designed for long-term operation. The process of creating hot-melt models assumes the use of thermal welding of the coat on the substrate. In this case, the ribbon with fibers is wound on a tube with a hot surface, as a result of which a monolithic bundle of a fur coat and a roller is formed.

Models with interchangeable fur coats differ universality and practicality of application. Installation of the working element on the roller of this type is made with the help of special plugs. In the beginning, the surplus fur coats are forced along the length into the base of the tube, and then the cotter pin and bushings are fixed.

Classification according to purpose

As an entry-level it is worth considering a variety of mini-rollers. These are small devices with rollers, the width of which rarely exceeds 15 cm. Such models are recommended for painting in hard-to-reach places or with small amounts of work. However, the most common was a standard paint roller. Types of fur coats in this case are used all without exception, and the sizes can be different. Such a roller can be made and painting a flat surface, and provide protection for weakly-relief areas, as well as to make an equalization using a water-based solution. In professional circles, facade models are more in demand, their fur coats are usually made of fur with a pile of the order of 20 mm. With the help of such a roller, it is possible to perform not only typical painting tasks, but also to cover qualitatively large areas of problem surfaces.

Selecting the optimum roller for painting

When choosing the right tool, it is important to balance the two opposing qualities. In particular, the roller must retain the coloring mass on its fibers, but at the same time it is easy to give it to the working surface. In order not to miscalculate in this choice, it is necessary to take into account both the properties of the color composition and the performance characteristics of the fibers of the fur coat. For example, fur rolls for painting are best suited for paint and varnish, polyester models perform well in water-based solutions, and the velor tool is suitable for water-dispersion and alkyd compounds.

Auxiliary devices for painting

In such a responsible and delicate operation one can not do with one roller. First of all, you should provide a container for paint. The traditional way of dipping an instrument into a bucket is irrational and wasteful. It is better to buy for this purpose a special bath, divided into two parts. It will also be useful to prepare a paint brush. Although the roller is a paint roller, in theory. Should replace its function, in some situations it is more convenient to use a more compact tool. For example, no coats will paint the corners as qualitatively as the brush does. Expand the functionality of the roller will help and handle-holder, through which you can reach remote sites. In addition, it is worth noting the need for personal protective equipment - a traditional set of painter in this part provides a respirator, glasses and gloves.

Rules for the use of the roller

On the part of doing this procedure it seems simple and easy. But to get a high-quality coating, several important painting rules should be considered. Start the work from the light source, so that no transitions are noticeable. In this case, the joints, corners and transition zones are painted in the first place. Uniformity of the application of the paint is provided not only during the process of painting - for example, after dipping the roller into a composition it is necessary to carry it along a ribbed surface. This will allow the application of a coat of paint without divorce and smudges. Use the paint tool carefully, without jerking and strong pressure. The direction of movement of the roller should be the same - this will also improve the uniformity of the coating and minimize the risk of defects.

Conclusion

Painting work is considered one of the most difficult stages of finishing activities. Usually in operations where high accuracy of handling of the tool is required, automated technical means are used. This sphere is not devoid of such devices, but they do not always provide a decent result. This increases the value of the work of masters, which use a paint roller in one or another modification as the main tool. Even paint sprayers, which are easy to apply, lose to traditional devices for a variety of performance parameters. And this is not to mention the advantages of the roller in terms of savings. First, it is one of the cheapest options from the entire range of paint tools. Secondly, it practically does not require maintenance.
