HYDROPHOBIZERSBIONIC EFFECT. QUESTIONS - ANSWERS

1. What is the protective function of BIONIC EFFECT water repellents?

The basis of the impregnations is a fluorocarbon polymer with all its inherent properties. These water repellents are preparations with complex protection of the treated surface. The complex of protective properties includes: protection from moisture, from water and oil pollution, from acids, salts, alkalis, UV radiation. To date, this is the only drug that provides such a complex of protective properties, while maintaining vapor permeability and surface structure.

2. What are the advantages over other impregnations?

Benefits of drugsBIONIC EFFECT:

  • All water repellents are water-based and safe for humans and the environment.
  • Simple application of preparations in any available way (brush, roller, sprayers)
  • They do not form films, unlike acrylic or organosilicon (silanes, silicones, polysiloxanes) water repellents
  • Self-healing and self-regulating system (a slightly damp surface, which can form, for example, during precipitation for a very long time, after drying, has the whole complex of initial properties as a result of self-healing and self-regulation of the structure of the water repellent)
  • Can be applied to horizontal surfaces with high abrasion resistance

3. How do water repellents work? Operating principle.

Penetrating through the pores of the surface of the processed material (natural and artificial stone, brick, concrete, wood), water repellents envelop them from the inside at the entire depth of penetration, without clogging and leaving the surface breathable. The penetration depth depends on the density and porosity of the material. For example, paving slabs from different manufacturers vary greatly in density and porosity due to different manufacturing methods (molded, vibro-casting, pressed, hyper-pressed) and the cement used and various additives. This also applies to decorative artificial stone.

4. How to properly apply on the treated surface? Application method.

All brands of water repellentsBIONIC EFFECTapplied to a clean and DRY surface. Preferably in 2 coats on a “wet-on-wet” basis to enhance and maintain the treatment effect.

Application according to the “wet-on-wet” principle means: application of the 1st layer on a dry and clean surface; after absorbing moisture and slightly drying, the 2nd layer is applied. Before applying the second layer, you should not give time for the applied water repellent to dry, because after the 1st layer has completely dried, it will simply not be possible to apply the second layer, since the surface will acquire water-repellent properties! And it will not let the water repellent inside the substrate.

When applying BIONIK MBO2 and BIONIK MBO6 on horizontal surfaces, do not leave puddles to obtain a uniform effect! Gently “disperse” the remaining puddles with a brush or roller or blot with a rag.

5. Can it be applied on horizontal surfaces? Operation under load (floors, paving slabs…) - resistance to abrasion?

All water repellents work on horizontal surfacesBIONIC EFFECT. When using water repellents with the effect of "wet stone", follow the application technology and do not leave puddles. The treatment effect is resistant to abrasion at the entire depth of penetration of the drug deep into the substrate. For paving slabs, paving stones, a special preparation BIONIK MBO6 has been developed, which is a microemulsion and easily penetrates even into dense surface structures. But it can also be used to obtain the effect of "wet stone" and BIONIK MBO2. It all depends on the density and porosity of the surface.

6. On what surface can water repellents be applied?

Water repellentsBIONIC EFFECTcan be applied to any absorbent surface.

7. Influence of temperature on the treatment effect (ovens, fireplaces).

Elevated temperatures after surface treatment with water repellents only increase the hydrophobic effect and protective functions.

8. The formation of spots, stripes, the so-called "efflorescence" on the treated surface. Common drug application errors.

The main mistake when applying preparations is a dirty or wet surface! Under the conditions of application, the formation of any irregularities, spots, stripes is excluded. In addition, the full fixation time is 24 hours! If the treated surface is used before 24 hours has elapsed, or if the surface is exposed to moisture, any chemicals during fixing, it may cause uneven application, spots, streaks, etc. You must follow the instructions!!!

9. Operation of the treated surface at low temperatures in winter.

Low temperatures do not adversely affect the treated surface. The acquired protective properties of the treated surface are preserved in the winter.

10. Differences between water repellents BIONIK MVO, BIONIK MVO2, BIONIK MVO6.

The finishing touch in the arrangement of suburban areas and areas around new buildings is the laying of paving slabs. It is very important not only to lay it correctly, but also to protect it reliably! A water repellent can easily cope with this task. The paths will not only not collapse, but will look aesthetically pleasing, moss and efflorescence will not form on them. And one of the main advantages of treatment with a water repellent is that you will forget about the constant need to knock down frost, sprinkle salt on the tile and other non-environmental reagents. Just brush off the frozen drops with a shovel or even a broom.

Applying a water repellent to paving slabs.

It is important that by treating the tile with a water repellent immediately after laying, you will save your time and money in the future. It is not uncommon for tiles to be partially destroyed the very next season after laying due to the penetration of water into it, followed by freezing and thawing. You can forget about the beauty of such a coating. And after a couple of years, you will have to change it altogether. Water simply does not penetrate into the treated tile, which means that it will delight everyone for many more years.

Reference

In order to protect the surface from stain-forming liquids and other contaminants, special compounds are used - water repellents, which provide:

  • prolonged dirt and stain protection effect in cases of oil and water pollution; facilitating the removal of dirt and stains;
  • improved appearance of the surface with a discreet glossy effect;
  • improved color vibrancy (slight wet surface effect);
  • reducing the tendency to fading, pollution;
  • simplification of ice removal.

What is hydrophobization?

Hydrophobization is a decrease in the ability of materials and products to be wetted (impregnated) with water and aqueous solutions. In contrast to the case of waterproofing, treated materials retain gas and vapor permeability, i.e. the surface "breathes". Hydrophobization is effective under conditions of periodic exposure to water (atmospheric precipitation, dew, etc.) and is not used in the case of constant (more than a week) presence of the material under a layer of water.

Why is water considered the "enemy" of building materials? Firstly, the water that has fallen on the surface of the building material in most cases is not clean. Most often, interacting with industrial emissions and exhaust gases, it turns into acid solutions, which, penetrating into the pores of concrete, cause its destruction, which varies in intensity depending on the acidity of the solutions mentioned above. Secondly, even pure water, penetrating into the material, significantly changes such a parameter as thermal insulation properties. Thirdly, water dissolves the salts that are part of the materials, which then form unattractive spots (efflorescence) on the surface of the product. Fourthly, a wet surface is a good environment for the growth of fungi and mold, which contribute both to the process of material destruction and to the ecology of the environment. And, probably, a particular danger is the freezing of water that has penetrated into the pores of the material. The resulting ice has a larger volume than the original water, and as a result, significant mechanical stresses arise in the material. As a result, when a certain number of freeze/thaw cycles are repeated, the non-hydrophobized material loses its strength with subsequent destruction.


How to use a water repellent for paving

  1. Conduct a paving inspection. Check compliance with the laying technology (slope, drainage drains). When using cleaners and water repellents, the instructions of the formulation manufacturers should be followed. Before starting the treatment of the entire coating, a trial treatment should be carried out on a small area;
  2. The surface to be treated must be free of dust, dirt and debris. Oil stains and streaks, paint residues are not allowed. Cracks (with the exception of hairline cracks) must be repaired. The surface of a newly formed product, as a rule, does not require additional processing;
  3. It is desirable to treat a dry surface; in case of emergency, processing of a wet surface is possible, however, this reduces the depth of penetration of the composition into the processed material and, as a result, the service life of the finished coating decreases. To treat a wet surface, water repellents of the NEOGARD - extra strong coating series on an alcohol basis can be used;
  4. Water-repellent compositions are applied with a brush, roller or spray quite plentifully, but without the formation of streaks. Particular attention should be paid to the treatment of surface defects (chips, deep scratches). When applying the composition in two layers, the second is applied after absorption, but before the first one dries (usually after 5-15 minutes). When processing paving made of natural and artificial stone, special attention should be paid to the absorption of the water repellent into the material. With a low absorbency of the coating, excess water-repellent composition should be removed before it dries with a soft cloth or sponge;
  5. Work on the treatment with water repellents is usually carried out at an air temperature above + 5 ° C. In the case of using the hydrophobic composition "NEOGARD for tiles", work on its application can be carried out at an ambient temperature above -10°C (14°F) in the absence of direct exposure to atmospheric precipitation on the surface to be treated;
  6. The necessary hydrophobicity of the treated surface occurs after its complete drying, as a rule, after 24 hours. During this period, it is desirable to protect the treated surface from direct exposure to atmospheric precipitation.

Since the advent of cement as the main binder for building concrete, there has been a problem of increasing the water-repellent properties (hydrophobicity) of products made from it.

Air-entraining

They are used to increase the plasticity of the concrete mixture and reduce the amount of water during its preparation. Therefore, products with the use of such additives should be more resistant to temperature changes in winter. But the strength of the product is reduced, according to calculations, by 20%.

Wetting and dispersing

They have a positive effect on the plasticity of the concrete mass, but the strength characteristics of the finished product are reduced.

Hydrophobic

A large number of such additives are currently being produced. They are based on insoluble soap, vegetable or mineral oils, which form a waterproof film on the surface of the finished product and, in calm conditions, increase its water-repellent properties.

These additives do not protect against the penetration of moisture under pressure, but lose their qualities in a short time. Such substances, applied on the outside, just provide the desired properties.

Before introducing hydrophobic additives in the manufacture of paving slabs, it is necessary to make sure that other qualities of the product will not be violated.

Advantages of Surface Treatment of FEM with Hydrophobic Compounds

So, with moisture, as the main "enemy" of durability, it is most effective to fight by external impregnation of the surface. For this, special hydrophobic compounds are used, manufactured industrially based on polyethylsiloxane substances.

The use of compounds can be twofold:

  • impregnation of finished products by the manufacturer at the aging stage;
  • surface treatment of the equipped tiling.

The result of the action of water-repellent compositions is as follows: they form a film on the surface, and atmospheric moisture, falling on it, is divided into small drops enclosed in a kind of fatty shell, due to which they either “roll off” from the surface or evaporate. Especially such impregnations are important for, because. fill any micropores.

Advantages of hydrophobic (water-repellent) compounds:

  1. Easily applied to the paving surface with a brush, roller. In the case of coating at the exposure stage - with a spray gun.
  2. The resulting organic film prevents moisture from entering the concrete structure and protects it from destruction, increases frost resistance and resistance of the top layer to abrasion.
  3. They are able to fill small cracks and prevent further damage.
  4. Prevent the appearance of whitish efflorescence, have antiseptic properties.
  5. Substances do not violate the anti-slip properties of the tiling elements.
  6. Protect the surface from oily contamination in the areas of gas stations.
  7. After drying, they are not visible, and PEM acquire brightness and expressiveness.
  8. Due to the organic basis, they are non-toxic and do not contain fumes harmful to human health.

Substances are applied to paving slabs (FEM) in the following order:

  • the treatment area is cleaned of contaminants with a brush or washing under pressure;
  • if there are fungal or mossy lesions, antiseptic treatment is carried out;
  • the tiling dries well;
  • application of a hydrophobic agent is possible with a brush, roller or spray;
  • the second layer is applied after the first has completely dried (after 2-3 hours at a temperature of 20°C).

The most common impregnations

In the trading network, water-repellent compositions are quite widely represented. Most of them are made on the basis of siloxane. Their action is identical: the substance penetrates into the depth of the tile, filling small cracks and creating an organic film on the surface. As a result, an obstacle is formed to the ingress of moisture and the destruction of concrete is prevented.

The most common impregnations:

  1. Ceresit CT10 is a silicone-based liquid. Protects concrete products from the appearance of efflorescence, damage by moss and fungus, forms an organic film, fills small pores and cracks. Applied in 1 layer.
  2. Impregnat Dry is a liquid for impregnating the top layer of paving slabs (FEM), pavers. The substance is capable of penetrating up to 5 mm. Organic compounds increase FEM frost resistance, abrasion resistance, and decorative effect. Applied in 2 layers.
  3. VOKA is a versatile substance with pronounced water-repellent properties. Penetrates 2-3 mm deep, applied in 1 layer, fully effective after 24 hours. The advantage is the long-term preservation of hydrophobic properties (up to 10 years). The disadvantage is the high price.

Thus, imparting water-repellent properties to concrete products is necessary to increase their strength, frost resistance, and hence durability.

paving slabs has proven itself as a reliable, inexpensive and aesthetically pleasing road surface for sidewalks, park paths and driveways. To be sure that it will last for many years, they use durable, factory-made vibropressed tiles and follow the established laying technology. However, this may not be enough, because in addition to the mechanical impact, the elements of the paved surface are significantly influenced by the climatic conditions characteristic of our country. Moisture and frost cause the greatest damage to tiles. Water penetrates into the smallest pores of concrete, where, turning into ice, it increases in volume and creates strong destructive pressure from the inside.

Choosing moisture protection

It is possible to significantly extend the life of paving slabs by protecting it from moisture. To do this, use the waterproofing of the outer layer or treatment with water repellents.

When waterproofing, an additional waterproof coating is applied to the tile. Most often, these are varieties of polymer varnishes or paints for concrete, which prevent the penetration of water and create an outer protective wear-resistant layer.

Water repellents are no less effective. These are liquids that penetrate the structure of concrete. paving slabs and providing water-repellent properties of the material. Capillary infiltration of moisture becomes impossible, while the pores inside the tiles remain open and provide good vapor and gas permeability. This means that excess water that has entered the tile will be removed from it naturally by evaporation (which is not possible with waterproofing).

Types of water repellents and processing methods

The main component of the water repellent is an organosilicon compound. It can be part of a liquid or polymer impregnation.

An aqueous water repellent is an emulsion with polymeric (silicone fats). They envelop the internal pores and surface of the tile and repel moisture. The advantage of this composition is the affordable price and the possibility of applying to wet tiles. However, the duration of such protection is short, it will have to be renewed in 2-3 years.

The polymer composition is more durable and is able to perform its functions for 10 years. The tile does not change the light, and provides good grip on tires and shoes. In addition, such impregnation protects against the effects of chemically aggressive substances (acids, salts). It is necessary to apply a polymer water repellent only on a dry surface. But heating the tile is not permissible, since the volatile components of the solvent will evaporate before it impregnates the concrete of the tile.

Treatment paving slabs water repellents is carried out in three ways:

  • The composition is applied to the laid tile with a brush or roller. The mixture can also be sprayed by watering or from a spray bottle. The best quality of hydrophobization provides a multi-layer coating.
  • The finished tile can be processed before it is laid. This allows you to apply impregnation on the sides and bottom of the tile.
  • Maximum protection of tiles from moisture is provided during factory processing, when a water repellent is introduced into the cement mortar for its manufacture. Buy such paving slabs only from serious manufacturers that guarantee its durability and impeccable quality.

The effect of hydrophobization of tiles manifests itself in different ways. You will see that after the rain it stopped accumulating moisture, efflorescence does not form on it. Even after several years of operation paving slabs looks like new, keeping a perfectly flat surface without cracks and swelling. A pleasant surprise will be the easy removal of ice from the paved road surface. In addition to maintaining the attractiveness of tiled paths, you will be pleased with the increased service life and reduced repair and maintenance costs.
