The modern needle roller is a specialized tool that looks like a paint roller. A distinctive feature of the tool is the presence of a surface covered with needles of various lengths. Such a roller with spikes is mainly used for laying bulk floors, as well as for removing wallpaper with your own hands. To fill such a floor, a mixture is prepared, the mixing of which leads to the formation of a large number of air bubbles. If they are not eliminated, then the bulk coating will have micro-hollows and this will become less durable. It is for their elimination that this tool is used.
Design
As a rule, a gear roller consists of a base covered with a needle cover and a working handle. In this case, the handle can be made of metal, plastic or wood. It is believed that metal is heavier, therefore, it is mainly used to work with large volumes. The metal tool is more durable and it is easier to bend drywall with it. It is also well suited for making wallpapers with your own hands.

Application
Needle rollers can be used for working with bulk floors or with drywall. Using this tool, you can easily bend drywall and give it the desired shape. In addition, it can be used to remove wallpaper.
When working with bulk coatings, the device is used to eliminate air bubbles. In order to eliminate them, it will be necessary to intensively roll on the screed solution distributed over the floor. These simple steps will help you get a smooth floor made by yourself.
Rolling the coating allows to reduce the degree of porosity, which will prevent destruction and wear. This is especially true in residential premises, where heavy furniture is supposed to be placed on the floor. Therefore, the roller for the bulk floor is the most important tool for leveling the screed. It is recommended to roll the flooring at least three times.

The choice of the roller is an important stage in the preparatory work for laying the bulk floor. These tools differ in many parameters that should be considered when choosing:
- According to the material, the tool can be metal or plastic. A metal appliance is more difficult to bend or break.
- In width. This parameter varies between 20-60 cm. Moreover, a wider needle roller for the bulk floor is better suited for rolling large areas.However, in some cases, for rolling hard-to-reach small sections of the floor where there is no access for a wide tool, it is necessary to use narrow models. Without such narrow tools, it is almost impossible to roll hard-to-reach spots, since wide rollers cannot be adapted to work in such conditions. If you are going to do wallpapering, here you can choose medium or wide tools. In order to bend drywall, you can use the product of any width.
- The length of the spikes that cover the surface of the roller. Basically, these devices have a game length in the range of 1-3.5 cm. If the needle length does not matter in principle for removing wallpaper with your own hands, then when working with a bulk floor, this parameter should be paid attention to. The choice of length depends on the desired thickness of the bulk floor. A thicker layer of mixture will require longer spikes. It is advisable to choose this parameter so that the length of the spikes is slightly larger than the thickness of the coating. Therefore, if you need to roll a thin layer of the mixture with a thickness of not more than 5 mm, then you should choose a needle roller for the bulk floor with the shortest needles. At the same time, the choice of thin spikes will eliminate even the smallest air bubbles. If you plan to work with gypsum or cement mixtures, it is better to choose tools with a maximum needle length. With their help, it will be possible to easily bend drywall.
- By type of handle. The tool can have both an ordinary and a telescopic handle. The second option is more preferable, since the telescopic handle has an adjustable length. It is better to choose it, since if you work with a long handle, you get tired much less. Using such a tool, you can easily bend drywall or roll the bulk floor.
When choosing a plasterboard roller, you need to ask the seller how strong the handle is and whether it is easy to bend. In addition, you should find out if it is resistant to aggressive environments, such as a solvent. It is desirable that there is a special casing that protects the instrument from splashes.

Thus, the needle roller is an indispensable tool for removing wallpaper and working with drywall or bulk floor. When choosing a roller, you should consider parameters such as its width, length of the needles, material and the convenience of the handle.
