How to remove the old floor. Dismantling Screed: Methods, Features and How to make a dismantling of an old cement screed machine for removing a cement screed

Competent dismantling of the old floor or outdoor coating It is known, as you know, a prerequisite for the successful work related to their update. In our article, we will try to tell you how to remove the old floor, without resorting to the help of third-party specialists, savingly saving at the same time at the repair work.

It is known that the floors in modern apartments Most often are equipped as follows:

  • pure concrete bases with synthetic coatings made of carpet, laminate, or a linoleum known to all of us;
  • wooden floors manufactured from individual boards or from a set of parquet;
  • floors decorated with tiles.

Preparatory activities

Before starting the gear disassembly, you should prepare the most necessary tool, the choice of which is determined by the type of floor covering. But in any case, you will need special means Protection of body and respiratory organs, mandatory when carrying out the work of this class (respirator, x / b gloves and headdress).

In order to avoid the spread of dust throughout the apartment in doorway It is advisable to fix a piece of moisturized fabric, and the thresholds are shown moored in water mats. In addition, you will need:

  • ordinary nail);
  • mounting hammer or sledgehammer;
  • screwdriver, pliers and ticks;
  • electric jigsaw or saw for cutting long boards.

Note that to disassemble the floor from tile tile (porcelain stoneware) You will additionally need to prepare a chisel and perforator. Sexual coatings used with carpet, as well as from laminate or linoleum, are significantly easier, especially if they are simply laid on a concrete base (without glue).

Removal of plinths

Dismantling of the flooring is taken to start with the removal of plinths, which can be plastic (with a cable built into them) or wooden. Disassembly of plastic blanks are starting with the removal of the decorative plank and removing the elements of fastening the product to the wall. Wood-sewed wooden plinths remove with a nail-cutter, and the dismantling should be started from the angle of the room.

In the event that the plinth is thoroughly painted in several layers of paint - you first need to find such a place where it is easily "coming up" with a flat screwdriver, after which it will be possible to use the nail-holder. In order to avoid damage to the wall decorative coating and for the convenience of fixing the position of the instrument under it, a small wooden plank (bar) is usually pubes.

Before removing old wooden floors, you should familiarize yourself with the order of their placement on lags laid on a concrete basis. When conducting these works, certain difficulties may arise with the removal of the first board, after dismantling which the case will go noticeably faster. To facilitate this operation, it is necessary to free the gap between the floor and the wall and pry a native of the extreme board in this place.

All other floor flooring are removed quite easily and can be dismantled with a hammer or a large flat screwdriver. To remove the nails driven into the board, you can take advantage of the first previously ticks.

If there is a circular saw, all operations for dismantling wooden floors are noticeably simplified. With it, it will be possible to cut separate "flooring" into smaller parts, which will be removed from the place of disassembly much easier.

For the case when the floorboards are attached with the help of self-tapping screws, your screwdriver, allowing you to quickly remove the fastening elements.

Removal of concrete screed

For removing concrete screed You will need to take first to remove from it. decorative coatingused for flooring. And only after that you can move to its dismantling, which is usually done by a shock way. For these purposes, you may need the following tool:

  • classic jackhammer;
  • perforator with a special nozzle;
  • sledge hammer, chisel or metal scrap.

Note that the use of special shock power tools significantly reduces dismantling time concrete grounds In the premises of any categories. But when it must be used to use personal protective equipment, protecting airways Human and his eyes from dust formed during work.

When preparing for dismantling, do not forget to make bags from durable materialIn which you can make broken pieces of a cement-concrete screed and accompanying any disassembly of trash.

Video

In this video, it is shown how to dismantle the wooden floor:

This video demonstrates the process of destruction of the old concrete floor with a jackhammer:

Concrete screed is a special coating that acts as an intermediate layer between monolithic reinforced concrete slab and finishing outdoor coating. With its help, the floor surface is aligned and the seams of intercutric space are filled. The height of the screed may differ and, as a rule, varies from 3 to 5 cm. After a while, it can no longer perform their functions, because concrete begins to crumble, peel and be covered by cracks.

To solve this problem, you need to disassemble a concrete floor. And below, we will look at how much the dismantling of the tie of the floor, considering the average market prices.

Floor screed and its main functions

The screed can be both a monolithic, made of cement-sandy mixture, and the composite, the basis of which represents a combination of several layers of gypsomment or ceramzite concrete. For higher reliability, the base is additionally reinforced with a steel grid.

Among the basic functions that fall on the floor tie, it is worth highlighting the following:

  • floor alignment;
  • protection of overlapping from negative external influences;
  • perception of load on supporting structures;
  • the basis for further laying of the floor covering;
  • heat distribution in floors having built-in heating.

3 main ways to dismantle floor screed:

  • Drilling.

It is used if you need to disassemble the entire surface, but a specific floor section. Moreover, drilling is not so noisy way and therefore best suited for repair in residential buildings.

  • Hit.

Removal of the coating is performed using an electric jackhammer, a grinder or perforator. But this method can be used only if concrete surface There are no reinforced elements.

  • Cutting

In most cases, a diamond cutting is used, with which the surfaces of any strength are removed. In order to perform work with a diamond instrument, uninterrupted water supply and nutrition, which is needed to reduce dust concentration in the room and permanent cooling of the equipment.

Why is it worth removing the screed?

It should be borne in mind that dismantling of the floor screed, concrete or cement, is performed if:

  • Scheduled overhaul Houses or apartments.
  • Requires a change in the floor level or reinforcement of the screed.
  • Repair or installation of pipes or cables in a concrete base is performed.
  • There were irregularities.
  • Outdoor tiles require replacement, because emptiness formed under it.
  • Specifications have deteriorated significantly and signs of the broom - cracks and bundles manifested.
  • The cement is seeping through the seams of the finish coating.

How much is the dismantling of the ball screed?

The main factors depends on the price of the service:

  • type of coating and its thickness;
  • the amount of necessary work;
  • the complexity of the task;
  • availability of additional services.

Therefore, give an unequivocal answer, how much costs 1 m 2 dismantling, it is possible only after analyzing the object, as well as the study of its features.

Floor repair in the apartment is complex technological processrequiring technical and physical training, and therefore, dismantling with your own hands is extremely recommended. An inexperienced worker can flood their neighbors and damage the plumbing pipes or stumble upon the wiring, which will lead to an accident or fire. Therefore, we recommend inviting professionals, which have required tools, the right experience and knowledge.

The average cost of dismantling the old concrete floor is presented in the table

Removing the old flooring allows you to prepare a surface for a better and new base. Also, as noted above, the demolition value depends largely on the area of \u200b\u200bthe room, the floor thickness, material, the method of removal and the presence of a reinforced base.

Before proceeding with the dismantling of the old screed, the finishing coating is performed, which should be paid separately. The price depends on what is required to remove - linoleum, plinth, laminate, parquet, tile or carpet.

conclusions

It is worth recognizing that the performance of high-quality disassembly of the screed is always very problematic. The procedure itself requires not only knowledge and experience, but also the availability of special tools and devices, the purchase of which can do in a decent amount of money.

Repair of an apartment or house is a difficult task for each person, especially for solved overhaul on their own. There is such a joke: if you want to know how much money is needed for repair, then carry out the necessary calculations of the cost of building materials, tools and the like and multiply this amount by three. In other words, repair is not cheap, so many tend to make it with their own hands with the least costs.

Where to begin?

Repair of an apartment or private house starts with various draft works. It is necessary to disrupt old wallpapers, replace windows and doors with new ones, and most importantly - replace the screed on the floor of the room. The screed is dismantled in cases when it was flooded more than a year ago, and she managed to significantly lose their heat and sound insulation properties. The dismantling process is a very time-consuming and painstaking work, however, if you try and attach the maximum forces, then to spend it completely under the power and yourself. Many people want to do it without mistakes, while retaining their family budget.

Before starting repair, you need to take into account all factors. You need the Council of the Wizard for the repair of apartments and houses, he will give you the answer to many of the questions you are interested in.

What is a screed?

Call called durable coatingwhich is located between the reinforced concrete slab and the upper floor layer. With this coating, the floors indoors are aligned, slots and cracks are removed. Between the screed and floor of the room there is insulation, noise insulation or waterproofing. They create additional comfort inside the residential premises. Under the tie is reinforcement. His removal will not be much difficulty. Be careful during the dismantum of the floor screed, do not overdo it and do not destroy the bearing walls.

Floor screed happens:

  • in the form of monolith - mixtures based on cement and sand;
  • composite - several layers of plaster and cement or ceramzite concrete.

To achieve the greatest strength, the monolithic screed is reinforced by a metal mesh. A cochetic screed has high strength, waterproofing, as well as thermal insulation properties. Among all the repair and construction work One of the most popular is the disassembly of the screed.

Dismantle or restore?

Dismantling you can easily perform with your own hands. Do not start repair, if you do not have the necessary builder skills, nothing is sense in this matter. In this case, you need to seek help to masters from construction organizations. All sorts of newspapers and magazines are simply faster than the proposals of construction and dismantling services.

Over time, any floor covering comes in disrepair. Concrete can start painting, peel and crack. In such a situation it is worth deciding, to dismantle the old tie or she will still serve. Basically, the masters advise to make disassembly screed. Such work is cheaper than recovery.

There are moments that need to be taken into account:

  • Is there any need to make the floor below.
  • Bad appearance Floor. Perhaps it will be more profitable to simply establish it again.
  • Low quality cement.

  • It is necessary to repair communications or pipes that are located under the flooring. Perhaps you have to install new ones.
  • Whether overlapping the premises on the lower floor the extra weight of the upper floor.
  • Working with a jackhammer is dangerous.

Houses that were erected in the middle of the 20th century, had a wooden or mixed floor: Wood beams put on top to metal, and in the toilet and bathroom there were plots with elements of reinforced concrete. The process of dismantling concrete floor has its own characteristic features. If you removed the old cement screed, and now you want to start the process of filling a new one, then you will not allow you to implement this project, since the total weight of the cement solution will be large, and the load on the overlap will significantly exceed permissible norm. It will be the right choice in favor of setting a screed on uneven places of lighter building materials.

Functionality and price

Screed plays an important role in the design of residential premises.

It performs such important tasks:

  • allows heat evenly distributed across the floor.
  • Protects overlaps from various deformations.
  • Aligns the floor, eliminates irregularities and cracks.
  • Creates sound and thermal insulation indoors.
  • Takes part of the load on itself, which helps unload the carrier design.

Types of hardware

Exist different types Floor screeds:

  • multilayer (composite). Contains gypsum and clay;
  • solid (monolith). A solution that contains cement, sand and water.

The reliability of the coating gives the reinforcing steel grid. It will be necessary to use the grinder to remove it later.

Advantages and disadvantages

The main advantages of the screeds are as follows:

  • long service life;
  • reliability;
  • protection against heat loss, water penetration, noise;
  • suitable for parquet and other types of coatings;
  • low cost, which is important when compiling a common estimate;
  • withstands even a strong load.

Negative moments Consist in its difficult installation, doubling, a high price. It will be difficult to remove the screed if necessary, so it is necessary to use a semi-dry or sandy mixture. From the number of layers of the screed depends on the price of its dismantling, because the craftsmen need to make significant efforts for such repairs. When disassembling the screed, pay attention to all decisive factors. It is from them that will depend on the choice of toolkit for the process. You can apply a concrete machine or a shock tool.

Dismantling with your own hands

If you want to dismantle the screed without assistance, you need to remove all the layers of flooring from its surface. You will also need various construction tools. You can apply a sledgehammer, scrap, hammer - it all depends on the thickness of the floor covering. After successful and completion preparatory work You can start disassembling the old screed. Remember that it is necessary to correctly choose construction tools. There are several different methods for removing the old floor tie.For example, the impact method is very noisy, moreover, it is dangerous for overlapping the room, because it can damage the house and your neighbors. You will need to make a big physical StrengthWhat can harm your body.

Selection of tools

Although in the process of dismantling and there are some subtleties, to remove the screed you will need some tools:

  • perforators, hammers, sledgehammers, jackhammers, various saws are needed to cut the reinforcement, if any;
  • a vacuum cleaner;
  • plastic bags.

Think about your health and buy protection tools. In the process of working into the air, a lot of dust and dirt will rise, so protect your body as much as possible. The tools that you will apply to dismantle the old screed can be divided into two groups: manual and electric. Paid screed parsing electrical devices It will increase productivity, but this work will cost expensive.

To tools that successfully remove the old floor screed include:

  • concretera;
  • perforator;
  • borants;
  • shvonzerchik.

When working shock method, perforators, jackhammers and saws are used. These tools work extremely noisy. Do not be an enemy of your neighbors - observe the silence mode. Remember that in the apartment on the left, right, below, people also live on top. Do not be a source of night noise.

Tools for disassembly screed own hands Such:

  • scrap;
  • hammers;
  • chisel;
  • sledgeVolds.

It is necessary to work manually where there is no electricity, or work is small by volume. This process is slow and noisy.

All of the above tools will use you in your work.

Additionally, you will need:

  • overalls;
  • helmet;
  • respirator;
  • points.

The dismantling of the screed is implemented by the method of breaking the monolith into separate pieces. For the removal of cement residues pre-prepare durable garbage bags. Before the start of work, prepare the room. All furniture and other interior details need to be transferred to other rooms and cover the cellophane so that they do not dreamed. Dust will be very much. It is necessary to remove the plinths, the old flooring. In case the coating is reused, separate it from the floor with marginal caution.

If the coating is dreamed, it is simply climbing, torn and disposed.

In most cases, when repaired, it may be necessary to make a dismantling of the floor screed concrete or cement. It is easier to make a screed again than eliminating problems with old, especially if there are many of them.

Immediately it should be noted that such work requires skills and skills. Dismantling the floor screed can of course, and with your own hands, but in this case you risk getting unfinished, or poor-quality work.

Pouring polymer and cement-polymer bulk floors have become relatively recently practicing. Thanks to their impressive periods of operation, few owners of premises with an innovative finish have come across dismantling. There were no official technological prescriptions about this. However, masters from the repair sphere have their own considerations on how to remove the bulk sex, there are tested methods and developments.

Methods for removing bulk floors

The reasons for dismantling the bulk of the floor is quite a lot. Among the standard prerequisites, poor-quality performance, non-compliance with technologies, unauthorized change in the composition of the mixture fill.

A list of more impressive reasons leads the desire of the owners to arrange a "warm floor" system in rooms with a small height of ceilings and similar good prepositions for radical alterations.

The choice of a liquid removal method is influenced by:

  • The composition of the solution used in the pouring. It is important that a polymer leveling solution was used or a mixture on cement or plaster basis.
  • The purpose of the fill. Mixtures with cement or gypsum base solve problems of alignment and formation of the base for further laying of finishing materials. Polymer compositions serve finish coatings Or substrates under the finishing decorative layer.
  • Final thickness. Formulations with cement or gypsum base are poured with a layer with a power of 1 cm to 8 cm. The optimal thickness of the polymer floors is 2.5 mm. The maximum limit is 5 mm. The minimum thickness can be 0.3 mm of polyurethane coating and 1.0 mm methylteatrylate finish shell.
  • Option of device tie.. More precisely, the screed is connected with the base or between it and the basis is an insulating layer. Isolation prevents the diffusion of the bulk gender and the R / B bases. If it is not, then the molecules of the poured solution are partially penetrated into the overlap, which significantly makes it difficult to remove it.
  • Technical condition. It is necessary to find out the localization of damage and decide on the appropriateness at all at all dismantling.

The technical condition of the floor does not matter if capital alterations or redevelopment will be carried out in the room. A completely different situation when distributing defects by 10 - 20% of the total area.

It is not necessary to remove the screed or decorative finishing shell completely, if there is an opportunity to eliminate only swollen or cracking sites.

The methods of dismantling the bulk sex applied to date require impressive labor efforts, do not spare customer wallets and overlap materials. Costs may be in a very solid amount. Because if there is a possibility not to resort to capital transformations, it is better to carry out partial deletion of bulk sex or local repairs.

Dismantling of the bulk screed 3 - 8 cm

Works on full removal of the screed are often performed much easier and faster than clipping fragments or almost jewelry removal of surface convexities. However, it should be remembered that it should be taken for them, scrupulously weighing costs and an estimated result.

Operation to complete the removal of the screed is made in the following cases:

  • An increase in the height of the ceilings in rooms with a multilayer powerful screed.
  • Preparation of the foundation for the device "Warm floor" system, if the height of the ceilings does not allow it to reduce it by another 7 - 10 cm.
  • Low adhesion screed with the basis, if a strong grip is assumed throughout the area.
  • Wear an old alignment layer that requires capital replacement.
  • The cracking and dust of the base gender, eliminating the implementation of further arrangement of the room and residence in it.

Disassembly is made by banal destruction of the screed by a perforator. To facilitate the solution of destroying tasks, the gender is preliminarily recommended to cut the grinder to segments.

Use need diamond Disc. It should be cut carefully, trying not to hook the overlap or lower layer of alignment. It is better not to deepen on the whole thickness, but leave around a centimeter of the uncut layer. Otherwise, serious repairs will be required.

After separation of the baccake of the floor to the sections in the fight for the destruction of the screed, the perforator enters. Two nozzles will be required to work with it:

  • Chisel-scarpel. With it, it is crushed by the bulk of the screed.
  • Peak. With it, work is made on the separation of a layer with high adhesion.

If the screed was arranged on a "floating" principle, there is no need for the use of peaks. The alignment layer is elementary crushing into small pieces, assembles in kraft bags and exported to the disposal place.

If the floor fledged on the concrete basis so that the clutch was maximum, then you need to act first in the scarpel, then clean the peak. The width of the scarpel may be different: from 3 to 10 and more see if necessary, it is worth using a few similar fixtures. Usually the largest scarpels in the most powerful perforators.

We did not know how to affect the issue of neat production. dismantling work. If the underlying screed in the process of dismantling the upper layer will be significantly damaged, it will also have to be removed. You can refuse to complete dismantling only if the black floor defects are not more than 20%, as well as the possibility of repairing restore specifications Basics.

Cleaning a screed made on a small area can be carried out without a perforator. But forces and time spent more than renting a drill-drill car.

Removing a screed up to 3 cm thick

Thin ties created by pouring the solution with plaster or cement baseare removed much more difficult than more powerful layers of alignment. They are rarely satisfied with the "floating" scheme.

Basically poured to eliminate the relief of the concrete black floor, with which the leveling screed must make the most complicated.

Reasons for disassembling thin layers of alignment are much smaller, this is:

  • Partial detachment from a concrete basis. Manifests itself in the form of "coverage" of individual sites. It happens due to insufficiently dried before the pouring of the draft floor, poor preparation for the pouring or the presence of oil spots on it.
  • The appearance of cracks on a large floor area. It occurs due to the violation of the proportions of the solution or the briefing of the manufacturer of the concrete mix.
  • The presence of bubbles and voids in the body of fill and on the surface. The traditional results of non-compliance with technology associated with a large amount of air bubbles in the mixture fill.

To the removal of a thin screed should be taken to high attention. Actions produced "on the machine" have to do a lot, but vigilance can not be lost. With careful movement, it is very easy to damage the draft base, to repair which will need to pour the floor again.

In priority, manual labor, from the tools - a narrow and wide spatula. It is better not to cut to the segments of the tie, if you don't have a brandy well enough. In the case of the use of the perforator, it is installed at an angle of 10 - 20ยบ to the surface of the screed. Among the allowed nozzles, only the peak, which, when crushing the floor, many masters are slightly sticking with free hand.

The layers of leveling thickness up to 1.0 cm are generally better to remove the mobile installation intended for grinding concrete. For one-time work it is more profitable to rent.

The vacuum cleaner is connected to industrial options, which in the process collects and removes malicious dust. A thin layer to 0.5 cm can be cut off with a grinder, using it not as a cutter, but by appointment as a manual grinding machine.

Local elimination of alignment layer

The dismantling of the screed areas is made according to one of the above schemes, depending on the thickness of the layer and the technology of its fill.

The cleaning work of the bulk section is carried out as follows:

  • Marking of a plot with defects. It is carried out so that between the edge of the cracking zone and the line of the future dismantum there was a minimum of 10 cm.
  • Cutting a piece of floor with a grinder. It is performed strictly according to the outlined lines.
  • Grinding screed inside the cut plot. It is performed by a perforator with a peak or chisel and spatula. Without fanaticism with the desire not to damage the draft base.
  • Preparation of the base of the area to the pouring of the new mixture, which according to the composition should be identical to the previous one.
  • Filling the solution to the segment of the floor freed from the screed, taking into account the future shrinkage in the period of hardening.

The magnitude of the shrinkage is usually indicated by the mixture manufacturer. If the thickness of the screed is insignificant, it can be neglected. If the alignment layer was 7 - 8 cm, the shrinkage should be calculated. Before filling around the perimeter of the remote segment, it is necessary to make a formwork from a thin sheet of plywood and pour the mixture with a layer that takes into account the magnitude of the shrinkage.

Having waited for a complete rejection of the floor within the repaired segment, the formwork must be removed. In the seams to lay the twine, then close them similar to the composition of the solution.

Removal of polymer floors

Manufacturers of leveling mixtures on acrylic and epoxy based Rently assure that their products are practically not subject to removal products. Remove the polymer floor is really impossible if the fill thickness exceeds 5 mm and the floor was arranged without a decorative layer.

To the tips not to arrange the polymer floor, without thinking about the consequences, it is worth listening to. Another question is that they remove it in extremely rare cases, because It is thin and smooth, to serve as a solid black base under the installation of the next coating.

Suppose that an urgent need to cut and remove the polymer floor arranged on top of the decorative print. For example, a black appaled basis was prepared poorly, as a result of which tubercles and dents were performed on the surface, or the drawing was tired of the owners.

Although the fill thickness allows you to tritely align the floor or impose a new film with photo printing on it, there are ways to remove the polymer shell. To remove manually, spathers or thin cutters use. Depending on the composition of the polymer floor, it can be partially dissolved or heated to facilitate dismantling effort.

Most of the bulk floors created with 3D effects are arranged over a thin layer of cement or gypsum alignment. In such situations, it will be wiserfully sacrifice the draft tie and remove the polymer floor with the draft floor.

The dismounting methods are equivalent to the methods of eliminating the screeds, depend on the thickness of the layer and on the diagram of its device. True, the destruction of this sex will require much longer time and effort.

For cleaning polyurethane, acrylic and epoxy coatings, leased means of mechanization can be used - grinding machines with a disk working body. If the floor area is small, and the usual Bulgarian is suitable.

The upper part of the polymer coating is simply cut, after which they scrape the lower part, reminiscent of the structure and plasticity softened linoleum.

And yes, after dismantling the old screed, most likely have to do a new one. And in order not to guess with the materials, we recommend that you read the review of the best self-leveling mixtures.

How to better align poorly flooded gender:

Methods to eliminate bulk floors are not too complex. If you have a real need, you can cope with dismantling it is possible.

It is important not to forget that in the destruction of hard mixtures, harmful dust is distinguished, when heated and use chemicals - Volatile toxins. It follows in a protective mask, it is best to add it to the points, you need to act reasonably and neatly.
