The goal of any responsible renovation is to return the building to its original condition and extend its service life. The threat to the long life of a building is the development of corrosion in its structure. Corrosion of a material increases the volume of the element that that material makes up. In reinforced concrete, an increase in the volume of the reinforcement causes the eruption of the part of the concrete that serves as protection for the reinforcement, which results in a violation of the function of the concrete-reinforcement joint.

DRACO® FIX 190 is a two-component coating based on polymer, cement binder and corrosion inhibitor for protection of reinforcement in concrete structures against corrosion.

For proper application, the concrete around the reinforcing iron should be removed so that DRACO® FIX 190 can be more easily coated around the bars, all damaged concrete removed with appropriate tools and, if possible, the degree of penetration of carbonic anhydrites into the concrete (carbonization).

If there are separate or listed layers of corroded iron, they must be removed. In this case, cleaning by sandblasting or high pressure water is recommended. If this is not possible then effectively scraping or brushing with a metal brush to completely remove the separate parts and any trace of oil, grease and the like.

With new reinforcing iron, it is necessary to remove grease or limescale residues by sandblasting.

Method of application

• Pour component B into the can and gradually add component A with stirring without adding water. Stir until you achieve a creamy consistency of a product that is easily applied with a brush.
• DRACO® FIX 190 is applied with a brush of medium hardness of fibers in two coats, with an interval of 2-3 hours, and the ideal thickness of the coating is about 2.0 mm.
• The applied material adjacent to the surrounding concrete should be applied evenly with a brush so as not to affect in any way the adhesion of the subsequent mortar to the concrete. Application of repair cement mortar (such as DRACO® FIX 120 or DRACO® FIX 140) can be done 4 hours after application of DRACO® FIX 190. If repair is done with epoxy materials, wait at least 24 hours before continuing with the application.

DRACO pays great attention to protecting structures from corrosion – that’s why our products meet high quality standards. DRACO waterproofing systems are designed precisely to make your facilities safe and comfortable to live in.

Modern construction is inconceivable without concrete, which in combination with steel bars, reinforcement, forms the basic material for the construction. Although solid and durable, reinforced concrete structures are susceptible to impacts that lead to their weakening or compromise their load-bearing capacity. If we exclude damage from earthquakes or fire, as natural disasters that can have catastrophic consequences, the most damaging effect of concrete is water.

More precisely, water has a negative effect on the reinforcement in concrete, causing it to corrode. By corroding the reinforcement it increases its cross section, it swells, which causes stresses in the concrete and results in the rejection of the protective layer of the concrete. Corrosion reduces the load-bearing capacity of the reinforcement and thus the load-bearing capacity of the entire structure.

Reinforcement of concrete structures endangered by corrosion of reinforcement includes a series of actions that have the task of preventing the corrosion process and restoring discarded layers of concrete.

DRACO® FIX 130 is a one-component, micro-reinforced, cement-based thixotropic mortar, used for the repair of concrete and reinforced concrete elements, for smoothing concrete surfaces and filling joints. In accordance with EN 1504-3 meets the requirements of class R3.

Method of use

• Clean the concrete substrate and reinforcing bars of rust, dust, traces of bloom, oil, grease and unbound parts by sandblasting or pressurized water.
• Treat exposed reinforcing bars with DRACO® FIX 190 anti-corrosion protection (see the relevant Technical Data Sheet).
• Moisten the substrate to saturation, without lying water.
• Slowly pour DRACO® FIX 130 into the water container (4.25 l per bag). Mix for 5 to 6 minutes with a drill with a mixing attachment, at low speed, until a homogeneous mixture is obtained. Manual mixing may require a larger amount of water which negatively affects some characteristics of the mortar.
• Apply DRACO® FIX 130 to the substrate by hand or using a suitable machine plastering machine in a thickness of approx. 2.0 cm, taking care that the surface is roughened. For thicker thicknesses, continue to apply a new layer of “wet on wet” or in a layer of mortar, insert the reinforcing bars. The layer of mortar above each bar must be at least 2.0 cm thick.
• If the first coat is already dry, roughen and moisten it before applying the second coat.

As already mentioned, concrete has become an indispensable part of modern architecture – on bridges, industrial buildings or residential buildings. In the past, the focus of construction was on the construction of new facilities, while today the maintenance of existing structures is in the foreground.

Rehabilitation of concrete is always necessary when structural parts lose their functionality. In order to restore and permanently ensure the function of buildings or structural parts, we offer our DRACO solution systems.

We are at your disposal for all your questions and support!

Due to its properties such as economy, durability and diverse design possibilities, concrete has become an irreplaceable material in modern architecture, both in building construction and civil engineering.

Problemi sanacije betona mogu biti i vrlo složeni, ali DRACO ima odlično rješenje za površinske sanacije. DRACO FIX 120 je jednokomponentni, mikroarmirani, tiksotropni cementni mort kontroliranog skupljanja i brzog vezivanja koji se upotrebljava za konstruktivne sanacije i zaglađivanje betona.

It is used for:

• quick repairs of concrete elements, edges on columns, beams and girders and balconies
• quick reprofiling of surface damage on concrete: nests and broken parts of concrete and quick interventions with the aim of preparing the base for waterproofing
• quick installation of door and window frames and electrical installations. It has excellent thixotropy, ie. it becomes less viscous the more we mix it and then makes application much easier.

DRACO products are a basic prerequisite for protecting the durability of reinforced concrete structures. DRACO waterproofing systems are designed precisely to make your facilities safe and comfortable to live in.

DRACO SHIELD 500 is an elastic paint based on an aqueous dispersion of styrene-acrylate specially formulated to achieve high flexibility and excellent resistance to aggressive atmospheric elements. When it dries, it creates an elastic waterproofing film, excellent vapor permeability, resistant to corrosive agents.

The facade next to the roof is the most exposed part of the building. It is exposed to all atmospheric influences on a daily basis, which over time can cause degradation of the final façade layer and stains caused by the absorption of impurities from the air.

In order for the facade to retain its aesthetic and functional properties, it is necessary to treat it with a coating resistant to the harmful effects to which it is exposed. Elastic, protective paint DRACO SHIELD 500 is a facade coating that creates an elastic waterproofing film, excellent vapor permeability and resistance to corrosive agents.

The product is extremely resistant to aging, UV rays, frost and defrosting salts. It can be applied on new and old concrete and plaster surfaces.

Each surface requires preparation before applying the coating, so that all accumulated grease, salt and dust are cleaned, and in the case of old and plastered surfaces, it is important to remove all loose parts and repair the missing plaster. DRACO SHIELD 500 is applied to the prepared and dry substrate with a brush or roller.

Method of use

• DRACO® SHIELD 500 is ready to use.
• If necessary it can be diluted by adding 2-3 % water.
• Mix the product well with a low-speed drill bit before use.
• Apply the first layer of façade coating on a dry surface with a brush or roller, wet on wet.
• After 24 hours, at normal humidity and temperature (+ 20 ⁰C and 60 % RH), apply a second coat in the same way.

The facade, which you take care of regularly, will need renovation over time. Renovation of the concrete facade with DRACO products gives your homes a new face, preserves and protects your building. This is exactly what DRACO systems are made for. They make your homes comfortable and safer for you.
