Paint rollers: what are they used for

Paint rollers are a versatile and cost-effective painting solution that can be used in a wide range of applications. They provide a faster, smoother finish than brushes, have better coverage, allow smaller areas to be painted, and are capable of being used with both latex and oil paints. They are also easy to use for novice painters as it requires minimal experience before producing stunning results. Paint rollers provide homeowners with a fast and effortless painting experience.

Recommendation points



One of the important components of painting skills is the ability to choose and use rollers correctly, depending on the types of finishes and materials used. To keep the quality of application of the composition always excellent, study a small guide on the types of paint rollers and their use..

Rollers are a highly specialized tool characterized by a number of criteria. The first is the roller dimensions, length and diameter. The second is the material of the fur coat – the soft shell of the roller, which absorbs a certain amount of paintwork materials. Some materials have pile, and its length is the third main parameter of rollers..

Additional characteristics include the method of fixing the coat on the roller, it can be glued, hot-glued and removable. The removable coat can also be glued to the thin sleeve in one way or another. Thermal sizing makes the roller more durable, since the paint components do not affect the glue line in any way. Also, hot-glued rollers do not have bumpers at the ends, and they do not leave marks. Despite the high price, only this type should be given preference, simple rollers are used one-time and only for rough work.

Comfortable handle and reliable mechanism

Before proceeding to the selection of rollers for their intended purpose, one should dwell on the properties of ergonomics that are applicable to all varieties of this tool. First of all, it is necessary to evaluate the weight: the lighter the roller, the easier it is to work with. The main thing is that low weight does not come at the expense of reliability..

The handle of the rollers is usually plastic and has a special shape to improve grip. Here the choice is made purely individually, however, inexpensive rollers have little special differences in ergonomics. A significant difference can be felt by holding different models of rollers such as WOOSTER or Anza in your hands. A good paint roller is always modular: a separate machine, a separate roller and a splash guard. Naturally, the quality and quality of the tool should not cause any complaints: durable plastic of the handle and roller, yoke mount with polished bushings and double-sided fixation.

What size to choose

The roller size is determined primarily by the area of ​​the painted surface. The larger the work area, the longer the roller length, so less movements will have to be done to apply, and due to the large width of the strokes, the application will be more uniform. At the same time, the roller becomes not very convenient due to its greater weight, which is not suitable for all types of work. For example, ceiling rollers can have, among other differences, a reduced diameter, which reduces the weight of the absorbed paintwork.

In general, the rollers have three size groups:

  • small (up to 100 mm);
  • medium (from 100 to 200 mm);
  • large (more than 200 mm).

The first type is used in artistic decoration and when decorating complex surfaces, all kinds of niches and shapes. Medium rollers have a general purpose, this is the most common type. Large rollers are used when working on very spacious surfaces, for example for painting floors or façades.

The choice of rollers by the applied material

Each type of applied coatings corresponds to its own roller material and often the paintwork manufacturer indicates it. If not, the principle of roller selection by material is easy to understand.

First of all, the roller must tolerate well the influence of the chemical components contained in the composition. All kinds of primers and antiseptics are almost neutral, so they are applied with cheap polyester or foam rollers. Some types of paints, especially textured ones, can only be applied with polyamide or flock rollers, and oil or alkyd-based paints with velor and fur.

To create embossed coatings, textured rollers are used that have a bitmap or a closed pattern on the surface. The depth of this relief is determined by the viscosity and density of the applied material..

An important role is played by the degree of absorption of the applied composition, which depends on the hygroscopicity of the surface and the density of the paint. The absorption capacity of the rollers and the composition must be adequate: for the application of primers, rollers made of highly porous materials – foam rubber or polyacryl – are used. For thicker water-dispersed paints, polyamide rollers are used, and for thick varnishes and paints, chemically resistant fleecy materials.

What should be the length of the pile

The longer the pile at the roller, the more porous and uneven the surface it can paint with high quality. For smooth putty surfaces, this parameter is not particularly critical; it is preferable to use velor or foam rubber rollers, since they do not foam liquid formulations when applied. Flock coats are used for finishing glossy surfaces.

To paint wood or wallpaper with a mild texture, use polyamide or fur rollers with a pile length of 6-14 mm. To paint textured plaster or bark beetle, the pile should be even longer – 16–20 mm. The peculiarity of rollers with a long pile is that they pick up more viscous and thick materials and can spray them. Therefore, such rollers should be carefully wrung out, especially when painting ceilings.

What is the difference between ceiling rollers

Since ceilings are always characterized by the highest demands on the quality of the finish, rollers should be used made of the best materials: fur, velor or polyamide. Special ceiling rollers have an uneven coat structure, in which the deep layer is denser than the outer one. Due to this, the roller absorbs more of the composition and gives it evenly with stronger pressure..

Rollers for painting ceilings are often equipped with a semicircular casing that protects the painter from falling splashes. This is especially useful when working with high ceilings and using a telescopic boom when you have to stand directly under the area to be painted..

Separately, it is worth mentioning such material of the roller coats as “golden thread”. Due to the fact that the pile is reinforced with a very thin metal wire, the roller does not get confused and serves for a very long time, while the application quality is always excellent.

Special types of rollers

In hard-to-reach places and on uneven surfaces, rollers with machine tools of a special design and shape should be used. For example, rollers can have a parallel handle and roller to paint interior cavities and closely spaced surfaces when there is no room for free hand movement..

The machines can also have an extended spoke to expand the working area. The length of such rollers can be up to 100 cm, which is convenient when painting ceilings from a scaffold or stepladders.

For rollers with a width of more than 250 mm, special machines are used. In them, the roller is attached on both sides with a forked knitting needle, the fixation can be automatic. Some types of rollers have an adjustable mounting gap, which allows the use of rollers of different widths on the same machine.

A similar type of tool, but with swivel needles, is used for painting pipes. Strictly speaking, two rollers are fixed on the machine, which cross at a certain angle depending on the diameter of the pipe.
