Construction, renovation
Hydrophobicizing is child's play!
Because you can't hold an umbrella over your house!
Water is nature's greatest destroyer, the earth's most effective and versatile solvent!
Ever since mankind began building, water has been the main enemy of its creations and structures. Over the millennia, man has developed countless construction techniques, used countless building materials, and invented them to prevent or at least mitigate damage caused by water.
Due to water damage to buildings, the preservation and renovation of buildings requires a continuous high financial outlay, which means a very large financial burden for countries, companies, and families. At the national economic level, this means several billion forints per year. If we protect buildings from water, we can stop the destructive mechanisms caused by water. Water damage to buildings can spoil the appearance of a building or damage the building material, thus making the continued survival of the building questionable.
The problem is caused by the porosity of the material! The more porous the material, the more it absorbs water. The goal is to prevent water from entering the building materials while maintaining the "breathability" of the wall. We offer you a complete solution for this.
All mineral materials used in construction have a porous structure, the extent of which can vary greatly. (We should know that the older a building material is, the more porous it becomes.) This different structure determines how much a material gets wet when in contact with water, and what kind of damage we can expect in the building made of it.
Damage can be significantly reduced or prevented if the building is made more water-repellent (hydrophobic), i.e. hydrophobized. The hydrophobic zone created in the building material significantly reduces the water absorption of the material, so the structure remains dry, so we do not have to worry about damaging consequences.
The essence of the hydrophobic treatment is that water cannot wet the masonry in any form.
This phenomenon (hydrophobizing effect) is caused by organic silicon compounds, silicones, which form a very thin layer in the walls of the pores, thus preventing the water absorption of mineral building materials, but maintaining the breathability (vapor diffusion) of the building, in contrast to the effect of various film-forming coatings (paints: acrylic, polyurethane, or epoxy resins).
The purpose of hydrophobization is to prevent the damage caused by moisture and moisture-induced damage to facades exposed to the weather. Hydrophobization, as a process, consists of treating the facade with a colorless, non-film-forming substance that prevents water and the harmful substances dissolved in it (SO2, NOx) - acid rain - from entering the capillaries (pores) of the building material.
How does water get into the wall?
Moisture can enter the wall in the form of vapor through condensation from the surrounding air, or in liquid form due to the capillary absorption of the building material, causing damage there. There are three main sources through which significant amounts of water can be absorbed by capillary action:
• Construction defects: defects in the building’s roof, poor or missing eaves, poor rainwater drainage, cracks in the wall, windows and doors (can be eliminated by using good technologies and quality materials).
• Water absorption of the facade in the event of heavy rain (cannot be eliminated).
• Rising moisture from the ground (can be eliminated by using good technologies and quality materials).
A prerequisite for the restoration of buildings is the elimination and avoidance of construction defects. Silicone building protection materials have been successfully used to solve the described defects for several years.
Silicones in building protection
Silicones are raw materials with practically unlimited possibilities of use. They are primarily used for their exceptional heat and cold resistance, water-repellent and separating effect, electrical properties, flexibility and, last but not least, their compatibility with the environment.
Silicones perform an important task in architectural activities and can be successfully used in building protection as a means of protection against moisture. Their special feature is that, due to their chemical structure, they repel moisture to a great extent, but at the same time they are water vapor permeable and very durable. These properties make them inherently suitable for the protection and renovation of buildings, on the one hand, and for the factory treatment of certain building materials, on the other hand.
In the construction industry, silicones can be used in several ways:
• Water-repellent material for the protection and surface treatment of building materials against moisture, additive in building material mixtures (e.g. plaster).
• Consolidant in monument protection: restorer of the original structure of loose, crumbling natural stones.
• In permanently elastic, weather-resistant joint compounds for exterior joints and in interior design (bathrooms).
• In patterning compounds, mold-removing compounds for building sculpture, for sculptures and museum objects.
• In coating compounds for horizontal, inaccessible surfaces.
• In injection agents for insulation against rising wall moisture.
• In inorganic/mineral paints and water-repellent agents for bases (natural or artificial stone).
• Binders for silicone resin paints and plasters.
• In water-repellent additives (for paints and factory impregnation of building materials).
• Primer for dispersion paints and plasters.
• Inorganic/mineral based oil repellents.
The operating principle of silicone-based hydrophobizers is as follows:
The organic compound groups attached to the silicon atoms act as an umbrella to protect the facade against water, while the oxygen atoms also attached to them form a very strong chemical bond with the minerals forming the pore walls. The formed hydrophobic layer not only provides perfect protection against moisture, but also protects against the damaging effects of dilute acids (acid rain).
Fighting rising damp
Only since the beginning of the 20th century have we used insulating surfaces (e.g. bitumen paper) in construction to isolate the horizontal moisture in buildings. In old buildings that do not have such insulation, either special techniques were used to allow the moisture in the walls to escape without significant damage, or the rising moisture could cause significant damage: the water resulted in the peeling of plaster and paint, salt efflorescence, the disintegration of brick walls, etc.
Damp walls cause an unhealthy climate and make some buildings unusable. This damage occurs when the base of the building is close to the groundwater level, or in clay soil, which makes it difficult for precipitation to seep into the ground. Until this problem caused by moisture has been solved, the success of the restoration of the building can only last a very short time.
The building can be subsequently, with the ground floor or must be provided with horizontal insulation at the same height as the floor level (above the cellar roof).
It is not always possible to decide purely optically whether a building suffers from rising damp. Before deciding to install expensive horizontal insulation, it must be clarified with appropriate tests (building moisture balance, water content, maximum water absorption, hygroscopic moisture, etc.) whether the damage is really caused by rising damp or by something else.
The following methods are used in buildings against rising damp:
• mechanical methods (consultation with a structural engineer is essential);
• electrophysical methods (the effectiveness of these methods is questionable, several variations are possible and have not yet been sufficiently proven);
• injection methods (structural engineering is also required here).
A number of requirements can also be set for protection against driving rain. These requirements are met by silicone-based products, which are applied to the surface to be treated in diluted form, with multiple saturations ("wet-on-wet" method), most often without pressure (e.g. with a garden sprayer) by flooding.
Depending on the absorbency of the surface and the amount applied, the impregnation agent penetrates the building material to a depth of several mm (or even cm). After the diluent (water, organic solvent) evaporates, a water-repellent layer forms on the pore and capillary walls of the building material. Due to the water-repellent coating of the capillary and porous masonry, the building material can no longer absorb liquid water. The impregnated building facade remains dry even in driving rain.
Since the silicone impregnation agent does not clog the pores and capillaries of the building material, the building material retains its water vapor permeability.
The surface treated in this way does not resist water pressure, as the pores remain open, and is therefore not suitable for insulating basements or swimming pools!
Some examples of usage:
Plastering during renovation
In the case of plaster renovation, when preparing the mortar for the top layer of plaster, a silicone-containing additive can be added to the water. When the plaster dries, the additive exerts its water-repellent effect and protects the building facade from water absorption in the event of heavy rain. This method can also be used for grouting materials (bathtub joints will not become moldy).
Lime paint for coatings
Lime paints should be applied very thinly, in several layers. To produce good quality paint, mature slaked lime that has been left to rest for a long time must be used. Since lime has a very low pigment binding capacity, it is advisable to use only white, i.e. unpigmented, or pastel tones.
Lime coatings are mineral paint systems, so they are particularly suitable for lime and lime-cement plasters.
However, lime coatings do not protect the building from moisture, and aggressive acid rain causes them to erode from the wall very quickly. Lime coatings can be effectively made water-repellent and thus durable by mixing a hydrophobic additive into the lime paint and by subsequent impregnation.
For silicate paints
In addition to lime paints, water glass-based paints are also used as mineral coatings. These coatings have the advantage over lime paints that they are more pigmentable and can be used to create stronger tonal coatings. Similar to lime paints, silicate paints do not protect buildings against moisture.
Silicate paint coatings can be made water-repellent by adding a solvent-free silicone resin emulsion to the so-called organosilicate paints - just like lime paints. The other option for protecting silicate paint coatings against moisture is subsequent hydrophobization with a general hydrophobizing primer.
