Paint rollers : description and characteristics of the species

Paint roller: description

tool designed this tool for drawing all kinds of paints and other decorative coatings.It consists of two parts: a handle and a spool.By design, the rollers are completely different.For example, they may be monolithic or collapsible, and are framed, with bearings and pins with the (very primitive).

fur coat, which is connected with the bobbin (core), can be mounted in several variants: removable coat, termokleenaya and glued.The first embodiment is fixed to the pipe with plugs.The second is fixed by thermosynthesis, that is "welding" coat to the reel.Well, the third - by a typical bonding to the base kernel.

What are the rollers in size?

As already stated, the tool is classified according to size and depending on the material from which it is made.If we talk about the first classification, that there are large, medium and small rolls.Their size is 180-250 mm, 100-150 mm and 50-100 mm, respectively.When the outer diameter may be quite different - from 15 to 69 mm.This depends on the manufacturer.

recommended for large areas of the big roller (or also called facade).But it is, because of its impressive size, is not very convenient for hands.The most comfortable are the medium and, in particular, small rollers.Recent so all can "get" the most remote places.Besides, they do not spray paint, in contrast to his "elder brothers."

They are less tired arm, and they are also very cheap.Select roll needed, depending on the area to be treated.In addition to all the above, it is to know how to paint the walls a roller, and to comply with certain technology.

Varieties of rollers on the material coats

Depending on the coat material, the following types of rollers for painting: polyurethane (foam), fur, velor and others.We describe in detail each type.

• roller coated polyamide (artificial fiber) has a pile length of about 8-20 mm.It provides good retention of the paint and its distribution over the substrate.It is used for all kinds of paints: for oil, and for water dispersion.Plus, it has a high chemical resistance.
• Polyurethane (or foam) applies only to water-soluble compounds: adhesives, primers, paints, polymer dispersion.Not suitable for corrosive components.It has a high elasticity, making it easy to restore its original shape.
• velor cover (thick and soft to the touch fabric) suitable for dyeing and finishing lessirovaniya.On the plus side it is possible to identify resistance to aggressive environments, and of the downsides - the fragility and inability to take the necessary amount of paint, because often it is necessary to dip the tool into the solution.
• fur coat from natural fur allows you to work with primers, paints, water-based and organic.Advantages can be distinguished from good absorption and distribution of the mixture over the surface.The lack of a fur roller - are different strings and the hairs on the surface.

In that case, when you have a question, how to choose the roller for painting, it is better to focus on the structure, which you will handle the surface (in the organic or water-based), as well as on the treated area (large, medium and small roller).
