Dedusting concrete floor: how to extend the period of operation

Qualitatively formed concrete floor is durable, reliable and durable basis. However, such a surface is not without drawbacks. Chief among them is the education in service of a large amount of dust, which negatively affects the health of the people, the equipment and tools. To eliminate such a problem will dedusting concrete floor, the methods of implementation which can be found in this article.

Causes of concrete dust

The cause of dust on the surface of the concrete floor associated with the erosion of its top layer. Structural composition of cured concrete Expressions conglomerate mixture, which included heterogeneous components are located. They differ not only in size, but also the chemical composition. The process of maturation of the cement stone is the formation of the silicate crystal lattice. It intersects with krupnofraktsionnymi insoluble fillers sand and gravel origin.

Concrete is composed of a plurality of microscopic and larger pores, which are filled with air, water and the cement gel substance. There are also present unbound chemically active substances causing the occurrence of erosion in the upper layers of concrete. This occurs at a constant mechanical action on the concrete surface, which porous upper layer begins to break down. Unbound cement particles and the chemically active substances are transformed into dust.

In addition, in the process of maturation of concrete comes out on the surface of the cement slurry. When it solidifies, it forms a weakened layer which is often a major source of dust occurrence.

To pylil concrete floor is not necessary to perform its hardening, the upper tie layer polymer mesh crystalline components, or to completely remove the unstable top surface. To do this, there are three methods of de-dusting surface. This hardening of the base by means of topping, covering special impregnations processing and polishing the floor.

Important! The best result gives the combined application of all technologies dedusting concrete surface.

Why is performed dedusting concrete floor

Dedusting - a hardening concrete coating using toppings, impregnation or grinding that is performed for extending the period of reliable operation.

If time does not stop surface erosion, over time, they will affect the deeper layers of concrete. This can not only lead to a partial, but total destruction of the screed.

Cement dust, which is formed on the surface, has a negative impact on human health. The smallest particles of cement and chemicals get into the eyes and skin, causing itching. Inhalation of substances can provoke airway disease and give rise to allergic reactions.

When the dusty concrete floor, equipped in workshops, garages, warehouses, dust has a negative impact on the harmonious operation of the equipment and machinery installed here. This will result in rapid tool wear and aggregates, which will soon get out of order. Crumbling concrete floor needs constant cleaning - otherwise it will be sloppy and untidy appearance.

If a concrete floor used as a rough base, even in this case should perform dedusting surface. If you do not, eventually coating starts to crackle and squeak, providing inconvenience in the operation surface.

The concrete floor covered so it does not pylil in a garage or other room

Destruction fugitive upper layer of concrete leads to a constant based on the formation of dust. From it you can not get rid of one stage, sweeping from the surface begins to break down as the next layer. To eliminate such a problem it is best to stage curing of the concrete screed, curable by special trains for dedusting concrete floor, which strengthens the surface and prevent its destruction over the whole period operation.

So that the concrete does not pylil, as well as to increase its strength characteristics used toppings and impregnation. Such reinforcements penetrate deeply into the pores of the concrete, clogging them, blocking the way of the formation and removal of dust. This sealing eliminates not only the process of concrete leaching, but also the destruction of his column as a result of exposure to moisture and chemicals, which can penetrate into it.

Dedusted floors are characterized by high strength, endurance, wear resistance, moisture resistance, the ability to withstand any loads and intensive impacts. Concrete substrates are coated with reinforced aesthetic appearance, which is achieved thanks to a smooth, flat and toned surface, if necessary.

The concrete screed coat to not pylila: features compositions toppingovyh

In addressing the issue than cover the concrete floor, not to pylil, should pay attention to the innovative technology in the form of topping. Such a protective mixture consisting of Portland cement, mineral admixtures, plasticizers and dyes. The first component serves for the connection of all elements of the mixture, thereby effectively filling concrete pore settable coated, eliminating delamination of the material.

Topping provides increased strength, durability of the concrete floor. Such a protective structure eliminates moisture penetration into the concrete column, which can cause destruction of its structure, followed by leaching surface. Underfloor toppingovym coating endures the impact of the chemical components, so can safely be used in garages, workshops and industrial halls.

The composition penetrates deep into the pores of the concrete, clogging them, which might extend the operation period of coverage, which is not destroyed by mechanical stress and other negative influences. Such means for dedusting concrete floor differs acceptable cost, that allows to inexpensively perform hardening of the coating. To a large extent reduce the cost of the process can be when used to create a low floor makes the cement, which will be able to compensate for the disadvantages of heavy-duty protective structure.

Topping discharged as a dry powder or a liquid formulation. The powder is scattered uniformly on the surface, and then compacted sand. When using a dry matter on a concrete floor formed stitches. This is a budget version of the topping. The liquid composition is uniformly applied to the surface, forming a strong and secure protective film which is resistant to moisture and chemical compounds. It is obtained a uniform, flat and smooth.

Varieties toppingovogo coating concrete floor dust

Modern topping comprises three compounds: quartz, corundum and metallic. For areas with an average intensity of use, the composition based on quartz sand. This mixture not only provides dedusting and hardening of the concrete surface, but also gives it an attractive appearance thanks to the presence of pigments in its composition.

Quartz topping for everything flooring in homes, educational institutions, warehouses. Another advantage of this option is acceptable costs.

The concrete process, not to pylil in areas where heavy equipment is located, there is heavy traffic and people? In these cases it is better to use corundum topping, which includes a mineral supplement in the form of corundum aggregate. This coating is characterized by high strength, wear resistance, abrasion resistance, moisture and aggressive chemistries.

The most reliable hardener is metallized topping, which is based on metal chips. It provides effective dedusting floor that preserves the integrity of the structure over the years. Furthermore, this improves the strength characteristics of topping concrete surface by 2.5 times.

Such a composition suitable for use in environments with an increased vibration, which is a massive heavy equipment, which is necessary for constant movement of heavy machinery. The disadvantage of metallized topping the high cost of the composition.

How to de-dusted concrete floor: improvement toppingovogo cover

The treated concrete floor to avoid pylil in the garage, workshop, production, storage, public or dwelling? The most correct solution is the arrangement toppingovogo coating. The composition may be provided in dry or liquid form, which defines the technology of its application.

The liquid mixture is applied to the fresh concrete screed or on the old floor. The first step is preparing the surface. It should be cleaned, repaired all the defects and sand. Topping applied to the floor by means of a sprayer or roller. The layer thickness is 2-3 mm. The mixture is quickly absorbed and freezes.

The dry composition is distributed uniformly over the entire surface after 5-6 hours after pouring the concrete screed. The process is performed by the metering truck. Immediately applied 2/3 of the total material. The composition begins to interact with moisture. Thus there is a crystallization process. On completion of the reaction indicates a complete and uniform darkening of the surface. The time has come to carry out grouting base sander. When massaging the mixture has ended, it is necessary to wait until the surface of the grab.

Important! For the best possible base important impregnate cement milk topping not to overdry the surface, thus further moisten it with water, it is strictly prohibited.

The next stage of processing of concrete floor from dust is to apply the remaining amount of the material. After 48 hours, the surface cleaning is done by using paddle blades. The procedure is performed in several steps to achieve a smooth mirror base.

The final process is to apply the solution as kyuringa which eliminates the likelihood of evaporation of moisture from the concrete. The material is distributed over the surface with a roller or spray. Upon completion of the cutting performed joints to eliminate cracking during hardening of the concrete floor base. Joints are filled with sealant. The cost of concrete dust control using topping starts from 1000 rubles /m².

The treated concrete floor, so it does not pylil: Features Special impregnation

To perform your own hands dedusting concrete floor can be used on special liquid impregnation of an organic or inorganic base. They penetrate deep into the thickness of the concrete, forming a solid and reliable connection. Organic impregnation in several varieties, namely in the form of epoxy, polyurethane, acrylic composition.

The polyurethane mixture not only promotes sex dedusted, but also performs a complete sealing of the base that entails an increase in strength, wear-resistant, shock-resistant and chemically resistant surface indicators. If it is used for dedusting concrete M350 (and more), the necessary depth of penetration of the impregnation - 2.3 mm and this value increased to 5 mm for the M150-M350 compositions.

Important! The polyurethane mixture has a sharp unpleasant odor, it is recommended for use as adhesives for concrete outdoors.

The epoxy mixture is discharged completely odorless. It is represented by a two-component composition, the basis of which are the epoxy resins. Such impregnation provides a durable, reliable, moisture proof, frost-resistant, durable base which is highly hygienic. The disadvantages of such a mixture may include its high cost.

Acrylic impregnation is preferred for the surfaces that do not take strong mechanical loads. It is used for concrete brand M200 (and more). Such a dust-free and hardened base will be characterized by an increased moisture resistance and high hygienic.

Inorganic flyuatami mixture are shown which include in its composition the sodium, potassium and lithium polysilicate compound. Impregnation penetrates deep into the porous structure of the concrete, causing it to the upper layer of chemical reactions taking place up to 15 days. This leads to the formation of insoluble, crystalline vitreous bonds that clog the pores and solidifying obespylivaya surface.

Important! Any impregnation may contain a coloring pigment which imparts a finished coating of attractive appearance.

Technology surface by impregnating dedusting

Before applying the treatment to the concrete floor must be treated sander. This is done in order to remove the destroyed upper layer laitance, dirt or oils, surface smoothing is performed simultaneously.

Grinding may be performed on the dry or moistened substrate. The latter option has high productivity and the ability to control the process. Wetted polishing method provides a highly polished surface.

Important! Processing floor sander promotes opening pores of the concrete base, which improves the efficiency of penetration of the composition into the interior surface, and forms a stable chemical compound.

Any impregnation is applied using a roller with tentacle structure, brush or sprayer. The composition is poured onto the prepared substrate strips. It should ensure uniform filling of the entire surface area. There should be places where the composition is rapidly absorbed into the concrete, with a minimum saturation zones where puddles formed. The inorganic composition is applied in one layer.

Polymeric impregnations base to be coated twice. The composition is distributed evenly over the surface using a squeegee or a silicone roller. After 30-50 minutes the mixture is applied to the second layer. The surface must dry for 20 minutes. When the time all excess impregnation should be removed with a cloth.

After 24 hours, dust-free and hardened surface can be colored enamel based on polyurethane, which is applied in two layers. After one day the surface is suitable for use. Price dedusting concrete floor using impregnation starts from 800 rubles /m².

Important! Dedusted by impregnating the surface has high strength several times, depending on the initial quality of the concrete base.

How to remove concrete dust: the method of grinding and polishing the surface

When deciding what to do to the concrete floor is not pylil, you can use another technology, which is a polishing surface. It can not only be preceded by further surface treatment using a topping and impregnation, as discussed above, but also to be the final stage of surface preparation for operation.

Grinding occurs dry method or implemented on moistened surface. The first method is in high demand. grinding process can be monitored visually. In this case, no need to wait for drying the surface. The main drawback of this method is the formation of large quantities of dust during the work.

Useful advice! To facilitate dry-grinding process is recommended for grinding technique connected detergent cleaner.

Dust removal of concrete using the grinder can be moistened on the ground, that is used mainly in the regeneration mosaic floors with granite or marble sputtering. The surface obtained perfectly flat, smooth, close to the polished. However, the process is distinguished by high labor intensity, low productivity, which is associated with the rapid clogging wet slurry of abrasive elements that are difficult to remove in a timely manner.

How do I remove dust from the construction of the concrete floor using a grinder

Grinding is carried out a mosaic-grinder, which is a ponderous installation equipped with an electric drive. The working part is equipped with one or more rotating discs with corundum or diamond segments, which differ in grit.

Useful advice! Grinding small area often enjoy a special nozzle for grinders.

De-dusted concrete floor using a sander can be on the old base or freshly laid screed. In the latter case, the first step in the process begins one week after pouring the floor, which will allow to remove the formed laitance layer, exposing the layer more durable. Finishing works are carried out after the complete curing of concrete, which occurs after 28 days.

surface grinding is performed in several stages. The first step is to remove the loose top layer, which is accompanied by exposure of the filler and the pre-alignment surfaces. Based on an old grinder removes erosion areas of concrete floor. This stage involves the use of grain to 30-40 units of segments.

Subsequently a base is carried out by means of special hardening impregnation. This type of work can not be performed in case of grinding finish. The final stage is to treat the surface with abrasive grit segments 100-400 units. to obtain a smooth, even dust-free floor.

In emergency situations is done polishing the floor surface with a diamond segments grit 1500-3000 units. to provide a mirror with water resistant, non-dusting base.

The process cement floor, so as not to pylil: the use of water glass

When the question arises, what process the concrete floor in the garage or workshop with the aim of de-dusting the surface, many are inclined to the use of liquid glass. Material presented viscous adhesive solution, which is based on silicate of potassium, sodium and other elements. The composition is produced by fusion of quartz sand and soda.

Manufacturers produce potassium, sodium and lithium water glass. The first embodiment is characterized by good adhesion and interaction with mineral surfaces. As a result, dust removal waterglass concrete floor is obtained a strong, moisture resistant, flame resistant base. Such an adhesive has the lowest cost.

Potassium waterglass also provides a solid surface which exhibits resistance to moisture, corrosive environments and other negative factors without loss of the integrity of the base. This type of structure does not create glare on the surface, so much appreciated when the exterior. Most common is lithium water glass, which can be treated concrete floor of any age, increasing its abrasion resistance by 20-40%.

Water glass is applied by means of hammers finishing brushes based mixed pile velor roller or spray. The latter option is useful for de-dusting surface of the walls.

Water glass is applied to a previously prepared, cleaned of dust, polished surface. A first portion of the composition was poured onto the base layer of 3.2 mm, spread evenly across the surface using a squeegee. The next layer is applied after 3 hours Not more than 3 mm thick. After drying the surface is ready for operation. Price dedusting concrete floor with liquid glass is 1300-1500 rubles /m².

surface dust removal - this is an important and necessary measure to extend the period of operation of the coating. The process of protecting the base can be performed with special impregnations, toppings, liquid glass, and grinding method. Each option is characterized by distinctive features. However, all the above methods dedusting provide strong, sturdy, durable and wear-resistant base.
