To create comfort in the house you need a beautiful flat floor. Regardless of the type of room, the material of the finish coating, alignment is necessary. For a perfectly smooth surface, a self-leveling floor is used, for the alignment of which a needle roller is needed. Where to buy it and which one to choose if there is no experience in repair work? What qualities should I look for?
What is it needed for?
A needle roller is needed to remove air bubbles from the self-leveling floor, peel old wallpaper and bend drywall sheets. In the first option, it serves as a layer equalizer, and needles pierce air bubbles in the solution.
The self-leveling self-leveling floor spreads well and evens out, but without the use of a needle roller, bubbles will remain in it, which eventually evaporate through the pores, and there will remain voids, due to which the floor will become brittle, will crack and swell.
How to replace?
Often the needle roller for the bulk floor is replaced with a regular brush. At the same time, the process becomes more laborious. In this way, it is unlikely to get rid of all air bubbles.
Special magnetic brushes are also poorly suited for this function, they are designed to clean the surface of the floor before pouring or the walls before plastering.
You can also independently build a tool for driving air: nail many nails onto the roller and attach a handle to it. To collect a quality tool will require enough time and patience. It will be interesting for someone to do this, but for someone it is easier to buy a finished product, since the prices are very affordable.
How to choose?
Among the many models, one is selected that matches the following criteria:
- In width - depending on the area and the presence of narrow passages.
- The length of the needles - depending on the thickness of the layer of the bulk floor.
- According to the material of the needles - iron is more durable and more versatile, plastic is cheaper.
- By the presence of a convenient handle and the material of its manufacture.
If you plan to use the roller further for other purposes, it is better to purchase a metal, more durable and durable. Only a heavy metal roller is suitable for bending drywall, it copes well with old wallpaper. Which needle roller to choose for the bulk floor depends on the conditions of use.
How to apply?
Do not be sure that the use of a needle roller will ultimately provide a quality floor. You need to carefully walk through all areas, the length of the needles should capture the entire thickness of the layer. Roller rolling should last from 20 minutes (for a small room) and more (instructions are on the packaging of the bulk floor). To obtain a solid base, the procedure is carried out up to three times. But the final result also depends on the preliminary preparation of the base, the correct choice of material and following the instructions for preparing the mixture from the manufacturer.
To bend a sheet of drywall, it is necessary to wet one side of it, then make punctures over the entire surface using a needle roller. The longer and sharper the needle, the faster the plaster softens. After these manipulations, the sheet will become flexible.
Wallpaper removal occurs in the same way: first the surface is wetted, then it is torn off by rolling the roller. The process will be even faster if you wet the wall with a special solution to peel old wallpaper.
Model Features
You can buy a needle roller for the bulk floor both in the usual building and in the online store. When choosing, it is worth paying attention to the following important characteristics: workmanship, width, needle length, handle comfort.
Rollers are available in sizes from 150 to 600 mm, the length of the needles from 8 to 34 mm. Needles should be 0.5-1 cm longer than the thickness of the mortar so as not to touch the mortar and deform the surface. Too long spikes introduce new bubbles into the solution. For a small room, the standard needle roller width for bulk floors is suitable - 240 mm.
The roller handle can be simple or extendable, with the possibility of adjusting the length. Forcing bubbles in a standing position, of course, is more convenient, so you should buy a model with such a device. The option with a short handle, for which you can buy a long one, is suitable only if the farm already has such a device, otherwise you will have to spend time looking for it.
The presence of a cover for protection against splashes is an undoubted advantage, but this is not a determining factor of choice. More attention is paid to the roller itself.
Construction tools must be durable, otherwise they may not withstand even one pouring the floor. Proven Russian manufacturers: Comfort, Sibertech, Styer, Zubr. Foreign companies: Matrix, Jenser, Bauma, Korte, 888.
Needle roller for bulk floor can be multifunctional and durable. Which one to choose depends on the operating conditions and personal requirements. The tool should not create the impression of insecurity, to fill the bulk floor you need a high-quality needle roller.
