The sanding machine for the floor with their own hands

Sanding (scraping) parquet and wooden flooring with their own hands. the choice of equipment

A floor covering is under considerable mechanical strain in the process of exploitation of the house, which causes fast wear and tear of the floor, and as a consequence, the need for repairs or replacement.

One popular material for flooring is wood. Installed in the form of parquet, solid or hardwood flooring, it is strong and durable. However, wood over time comes into disrepair and needs to be restored. To return the old wooden floor or parquet to an attractive appearance will help scraping and sanding. The essence of the procedure is to remove the worn-out top layer of wood using hand or machine tools.

How is wood scraping different from grinding of the parquet/floor??

Planing or scraping. the process of leveling the surface of the floor, by removing the worn surface layer of wood cutting tools.

Sanding. a similar process, but abrasives are used.

Today scraping and sanding of the floor can be considered synonyms, what is explained by the wide use of machine sanding, which is based on the use of abrasive materials.

Squeegee and polishing parquet is performed by different equipment for different purposes.

  • Work front: for scraping a small area of used hand tools, with a large area of work. grinders;
  • the condition of the flooring. In a neglected case, manual work will take a long time, the machine will cope faster;
  • Costs: manual smoothing and sanding of parquet is more economical than machine sanding. The latter is more expensive to purchase and maintain;
  • time. Manual work is by definition more time-consuming than machine work;
  • The artist. Professional teams use only machines, scraping parquet with their own hands is done manually or by renting a sanding machine.

Sanding and polishing parquet, what is the difference?

So, what is your own handcrafted parquet flooring sanding? It is the removal of an outdated and damaged layer from the flooring with the help of both hand and power tools. Sharpened plate of metal in such devices removes wood shavings from the floor, but such work is difficult and long. Also, if you do not have the proper skills, hardwood floor polishing will be of lower quality, because this process requires certain practical skills.

Scraping and sanding your parquet flooring. what's the difference

Rough sanding with coarse sandpaper is an easy substitute for sanding. The processes are similar, but sanding is less energy-intensive and noisy. Also a coarse-grained finish is used to bring the flooring to a smoother state.

But nevertheless let’s understand these issues in more detail.

How to scrape a parquet

Above we figured out what the process is, now consider the question: when the parquet requires rough scraping?

Once the roughness and scratches of the old flooring to tolerate no longer have no strength, the floor requires urgent updating. In this case you need to choose a method. manual or machine.

If you decide to use an ordinary hand scraper, you should immediately prepare for a long job, you may even have to spend a few days.

  • The first thing to do. Remove all furniture from the room, and the baseboards simply dismantle.
  • Next follows the preparation of the floor, which consists of removing trash, and then humidifying the parquet.
  • Now the floor is ready and after dividing the perimeter into several strips you can start processing. Progressive uniform movements to remove the old layer of wood, first along the fibers, and then in the opposite direction.

But if you simply do not have a couple of free days for processing the floor? Then let’s look at how to properly scrape your parquet with your hands using a special machine?

To start with the fact that such a cycling differs from manual, because it is much more advantageous to perform it with a drum or belt sander, equipped with coarse sandpaper (24 to 40 R). In that case a couple of days of work is only a few hours.

The only important issue is to check the electrical network in the apartment. If the voltage does not reach 220 watts, then you need to connect the machine directly to the switchboard.

And here the way of work is not much different from the manual:

  • You should also prepare the room by clearing it of things and furniture, as well as by removing the baseboards.
  • After moistening the flooring, evenly remove the old layer of parquet, while working with the right force pressing the machine.
  • Corners and hard-to-reach places should be scraped with the corner machine, do not climb into the place where it is not intended for with a belt sander.
  • In case you have missed a small roughness or crack, it will be better to treat this mini-area manually with the same coarse sandpaper.

That’s all, the floor is scrubbed and completely ready for grinding.

Correct choice of machine

It should be understood that the floor grinder, rented, will benefit only if its characteristics fully meet the conditions of the work performed.

  • the firm providing the service is widely popular;
  • Provided equipment is in perfect working order;
  • the firm has specialists who can provide the necessary advice in the selection of appropriate equipment;
  • each machine is provided with a full instruction manual;
  • The model range includes units with different capacities, the ability to work on different surfaces and the ability to work in hard-to-get-at places;
  • there is a possibility of providing additional equipment, such as industrial vacuum cleaners;
  • All the necessary consumables are available in the necessary quantities and at affordable prices;
  • reasonable rental cost of equipment and the amount of the deposit.

Of course, choosing the technique, you need to be guided in what kind of wood sander for the floor, what their differences and for what surfaces are designed for one or another model.

Sander varieties

Sanding machines are designed to process floors with almost any type of surface.

Among the main surfaces to be treated are the following:

  • Varieties of stones. shell rock, marble, granite;
  • Wood. parquet, wooden boardwalk;
  • concrete screed;
  • mosaic floor.

The design of all grinders is approximately the same. There are universal machines, as well as simple design, designed for grinding of specific floor surfaces.

Vibration machines

This type of device performs sanding by vibrating the work surface. Such machines have a motor with a rotating shaft and an eccentric. The sanding disc performs sanding due to the high speed of the motor and the small amplitude of the working disk. The disk is attached both with special clips, and with Velcro.

  • Flat grinders. equipped with a large rectangular shaped support foot. Such a wood sander is best suited for floors with a flat base.
  • Deltaschlifovalnye devices. small hand tools weighing 1 kg, having a base in the form of an iron, and they are designed for grinding of inaccessible surfaces. These can be places behind heating columns or radiators.

Keep in mind that the higher the vibration frequency of vibration sander, the rougher the surface will be processed.

Models of this type are often equipped with a dust collection system. This is very helpful, because the dust from the floor surface falls directly into a special bag. Certain models have the ability to connect with an industrial vacuum cleaner.

Drum machines

Machines of this type are the most popular of all devices, and they are designed for grinding the floor covered with parquet. They are considered universal and can be used for scraping and sanding.

In such grinding machines simple design, so they serve very long, in addition, they are easy to maintain, and abrasives can be used from any manufacturer. Sanding belts are easy to install on the drum.

Band type machines

Belt sander is used for rough sanding, scraping, rough sanding and smoothing out the surface of wooden floors. Sanding belt in them is guided by rollers, and thereby the floor is cleared.

Eccentric type

The device of such devices is to combine two types of movement of the working surface: rotation and vibration. When these movements are combined, the result is a quality sanding with high efficiency. On the sole there is an opportunity to fix replacement sanding sheets that can be attached by means of Velcro and on clamps.

Determining the type of machine on the principle of attachment of sanding sheets, it should be borne in mind that they will cost more on the velcro, but the abrasive change will be somewhat faster.

The quality of the surface directly depends on the diameter of the abrasive. the smaller it is, the higher the quality. At the beginning of scraping it is better to use large discs, and at the finishing stage. small discs.

Angular machines

These types of machines are designed for sanding inaccessible places. They are not used for processing large areas. They use a sanding disc as the working part. These machines are also popularly referred to as “boot” saws, they are considered the smallest.

Angle-type machines are very popular among builders because of their versatility, as such machines can process any coating, you only need to equip them with a certain disc.

Working with such a tool requires a person to be extremely careful. The tool must be necessarily equipped with a protective cover, protecting the person from falling fragments due to accidental destruction of the disk.

At the moment there are machines that can process corners, spaces under radiators and other hard-to-reach places, but they are not as dangerous. They are often referred to as angle grinders, but this is not quite correct. Such machines should be attributed to the planogrinding machines of vibrating type. They are easier and less dangerous to handle. This type of grinder is perfect for people who want to sand the floor on their own, but do not have enough skills to handle such equipment.

Mosaic-grinding type

Machines of this type are able to process these types of floors:

There are several variants of models of this type. At the heart of each is a metal casing with a motor inside. There are even versions with gasoline engines.

The unit is equipped with rubber wheels for easier movement on the pavement. For ease of movement, special handles are provided.

There is a motor inside the housing, powered either from 220 or 380 V. Through this electric motor is the rotation of the metal plate of a special shape (traverse), to which the sanding components are already attached.

Some of these include:

Depending on how small are the various components of the abrasive, will be obtained the appropriate quality of the machined surface. the crosshead speed also plays an important role in achieving the most efficient result. It can be adjusted for each individual type of mosaic sanding machine.

Is it possible to save on renting equipment?

The presence of the grinder for concrete floors, with a small area of the surface to be treated. a thing not at all necessary. In some cases (when not required and a particularly high quality grinding), it is quite possible to make processing, using an ordinary angle grinder. It requires a special diamond nozzle, the size of which depends on the flatness of the concrete surface: a significant number of bumps and valleys requires a diamond nozzle with a larger grain size.

It is possible to get by with cheaper versions of tools

Concrete grinding your own hands with the use of angle grinder can not be effective without first finishing the surface to be sanded. For example, large surface defects need to be putty, and existing (or identified during inspection) voids. redo. After all, when such grinding mechanical stress on the surface of the concrete will be very hard, and the defective layer can be splintered out.

Please note!

In all cases of grinding the concrete floor should get rid of baseboards: they should be finally installed only after full treatment of the concrete base.

Follow the safety regulations when sanding

Technology of grinding the concrete floor with their own hands

Consists in the sequential performance of the following steps:

  • Surface hardening treatment of the surface before grinding. Hardening compounds are divided into dry and water-soluble ones. The first grind into the surface layer of concrete, thereby increasing its strength characteristics. The latter, produced on the basis of water-soluble carbonates, penetrate through capillary channels inside the concrete surface and also contribute to improving its quality. Dry hardening mixtures are usually used for small areas.
  • Cleaning of the treated surface with a vacuum cleaner (if you do not feel sorry, you can, of course, use an old domestic vacuum cleaner, but it is better to rent a special industrial vacuum cleaner for this purpose). The treatment should be conducted immediately after the hardening surface treatment.
  • Grinding the concrete floor itself (if there are high demands on the quality of the final surface, there is also polishing).
  • Coating the treated surface with a special lacquer that contains polyurethane. Varnish should be applied in several layers immediately after polishing.

Safety precautions during grinding work:

Preparing the floor for the job

Regardless of whether the flooring is new or old, the flooring should be checked for defects. This: knots that fell out, the gap, the strength of fixing the floorboards, the presence of centers of rot, mold. If necessary, the strips are replaced, fused, the flooring is rebuilt, but the cracks sealed with sealant, putty and give a good drying.

Tip! If you add wood shavings into the putty or PVA glue, caulking cracks will be easier and the mixture will hold stronger.

To prevent the risk of breaking the drum of the sander or disc, the protruding nail heads recessed into the wood, and unnecessary nails pull out. Holes also need to be sealed, sanded with a sandpaper. Cleaning of furniture, dust and debris is a must, and then it is better to wash the flooring with a damp rag, but with the expectation that it has had time to dry before the start of work.

Door openings to veil the film, so that the sanding dust does not fly into other rooms. The door will have to be removed, as well as the baseboards. By the way, old baseboards are better inspected and also replaced. Windows must be left open, bulky furniture, expensive wall and ceiling cladding must be masked with plastic.

Sanding equipment

Treatment of the coating begins with one question. what to sand the wooden floor? Focus on the basic conditions: the total amount of work and the financial capabilities of the owner. When calculating the cost of sanding a wooden floor, you should choose the technology:

  • Manual. Labor-intensive and time-consuming work, characterized by low cost, but it is used only on local areas.
  • Machining. This option is good for objects of any size. You can sand the wooden floor as in a shabby and new condition. In addition, the grinder works quickly, shows a high quality of the procedure. Both standard and hard-to-reach areas can be covered with the machines. Of course, the grinder for the wooden floor is expensive, but you can rent the device by the day. it is feasible for any purse.

Choosing equipment, you need to pay attention to:

  • standard household or professional models. the latter are suitable for large volumes, have many features, but are much more expensive;
  • Connection single-phase 220 V or three-phase 380 V. three-phase grinder will not withstand every household network;
  • The dust bag is integrated or there is an adapter for connecting a vacuum cleaner. there will be a lot of dust, and not every house has a construction vacuum cleaner.

Assuming the renewal of wooden floorboards in a large house, it is easier to buy the device in the property. Household machine for grinding a wooden floor is estimated from 100-150. Professional units cost from 1000.

Drum-type machines

The device is designed for rough sanding of floors, treatment of hard-to-reach places and can be used for finishing passes. The tool perfectly copes with any volume, but it is important to properly set up the unit.

If your floors are new and smooth, you only need to remove burrs. just go over the floorboards lengthwise with a coarse and then fine abrasive. The size of the abrasive should be changed after a pass 2-3 times, coarse abrasive removes not only burrs, but also the old paint coating, well leveled differences in the level of the floorboards. The medium and fine grit sizes remove imperfections and create a flat, pleasant-feeling floor surface.

The abrasive drum is adjusted with nuts on the handle. You can set the pressure mode of the drum on the boardwalk. if there are many defects, a little more pressure will level them better. Before working it is important to check the balance of the drum: the slightest disturbance during processing will leave “waves” on the floor, and they are much harder to remove.

Important! The drum-type machine works with any sandpaper, the drum is mounted abrasive material (tape width 20 cm and 70 cm in length), fixed clamps and varies not only depending on the stage of processing, but also in case of rupture, wear sandpaper. By the way, consumables wear out quickly, this point must be monitored to avoid sanding the floor with an “empty” drum.

Belt equipment

Belt-sander. equipment that is used for primary deep processing, when you want to eliminate serious defects in the plank flooring. Operating element. a mobile sanding belt, closed on a special roller and held firmly on it. The device is necessarily equipped with a vacuum cleaner, a bag for dust collection, because the work with the equipment, a little dirt.

Important! Belt grinding unit allows you to choose from 3 modes of force applied to the surface: hard, medium, easy.

Degree of adjustment should be selected according to the type of defect. With a high speed of the abrasive belt and power, the device copes with the tasks:

  • removal of the paint coating and simultaneously several millimeters of chips;
  • Height adjustment of glued floorboards;
  • Cleaning particularly difficult areas of the floorboards.

It is important to know that after abrasive treatment small scratches can remain, so additional grinding with a fine abrasive or flat abrasive machine is necessary.

The nuances in working with equipment a little. belt machine quickly and easily installed on the work surface and just as easy to grind. The main thing is not to forget about the uniformity of movement of the belt, the level of pressure. The work order is also “along and across” strips of the floor to eliminate all defects.

Tip! To change the abrasive, you need to loosen the tension (there is a lever on one side). And to center the abrasive, you need to work with the regulator. it is located on the front roller on the side. The main thing. do not try too hard, so that the tape during the work did not slide off the machine.

Flat grinders

Thinking about how to grind floors of the boards for a mirror shine, you can not do without the flat sander. This is a unit of final finishing, also used for processing hard-to-reach places: under the radiator, on the steps, near the wall. The device is quick and easy to set up, compact in size, does not have a large mass. Work with such equipment must be fast. flat sanding machines can “pass” large strips of flooring, turning them into a smooth surface in a matter of minutes.

Fact! At one time the machine grinds a strip up to 30 cm wide, but it all depends on the size and number of discs (one or three). In this case, the angle of the surface is small, so the processing is extremely qualitative.

For long time treatment it is better to choose devices with power reserve (600 watts and more), but a domestic floor can be easily updated by the device with power of 200-300 watts. In fact, the flat grinder. it is an ordinary angle grinder, where you need to set the correct mode of operation: primary, final processing. In this case, you should pick up the speed of passes, do not forget about the balance. to check it in idle mode. But the lining on the platform can be rubber or plastic, the latter better “holds” the plane.

The basic process of grinding

After the first phase of the work was a success, it’s time to move on to its main part. grinding your own parquet. When grinding a paper of finer grain size is used, and as the end is gradually changed to an even finer variant. The whole surface is gradually smoothed and leveled, remove scraping residues, minor defects and putty residues, if it was used in the earlier stage of leveling. Parquet should become absolutely smooth and flat, like glass.

Under the stairwell, as well as under the radiators heating to treat the surface with the sander is rather problematic, it is in this case need a “boot”. This is a device that is designed specifically for hard-to-reach places, such as corners, joints, etc.д. Work with such a device should be very carefully, so as not to disrupt the overall flatness of the entire surface.

The final stage of the work

The entire surface should be vacuumed and remove debris, which will give an opportunity to evaluate the result. In any case, it is necessary to install the finest of their sandpaper in the machine and go over the entire area of the room again. So you’ll remove all the small flaws in the work, polish the surface thoroughly and finally prepare it for the varnish application. Do not forget about such a trifle as the width of the drum. At the very last stage on the grinding of the parquet with their own hands, the width of the drum should be the most minimal, which will treat the surface with care.

All that’s left is to take the lacquer and the tools for applying it and cover your new floor with it. If after reading this guide for beginners you have doubts, you should still ask for help from the pros. They will do all the work rather quickly and, accordingly, qualitatively, but for the money.
