Self Leveling Epoxy Coating Technical Specification

Preliminary Information:

Thephrase “general” in the specification name; It was placed due to the availability of different self-leveling epoxy coating system options, depending on the specific conditions of the application surface and the facility. The thickness should be determined according to the specific conditions of the area to be applied. Material consumption will occur according to the determined thickness. Self leveling epoxy coating applications are made in 2.5-4 mm. A special specification should be prepared depending on the characteristics and needs of the enterprise to be applied.

Temperature and Humidity:

Forepoxy coating application, the ambient and concrete surface temperature must be between + 10 ° C and + 30 ° C. The concrete moisture rate should be 4% by weight unconditionally and the relative humidity in the environment should be less than 80%. Relative humidity; It must be below the “Condensation Temperature”, also known as the dew point. Concrete moisture will be measured with a humidifier, when necessary, the ambient temperature will be increased.

Surface Preparation:

In reinforced concrete floors suitable for epoxy coating; Surface preparation is made in order to remove possible loose particles, weak slurry layer, oil and dirt layer, if any, and roughen and clean the surface. Epoxy coating surface preparation should be done with a vacuum ball blasting machine (Shot Blasting-Blastrac). Traditionally, marble polishing machines, diamond-tipped hand machines and rotatigers are used for this process. With these machines, sufficient surface preparation cannot be made to absorb the primer on the surface. It is allowed to use hand spirals where the vacuum balling machine cannot enter. At the end of the surface preparation process, the surfaces will be clean, dry, free from oil and dirt layer, and curing materials, if any. Weak concrete will be removed,eyelet gaps and holes will be repaired in accordance with the technique. Cement laitance on reinforced concrete surfaces will be removed by using abrasive equipment and the surfaces will be made open porous. The high places on the surface will be abraded, sanded and cleaned. All dust, loose and volatile particles on the application surface will be cleaned with a brush and vacuum cleaner.

Epoxy Primer Application:

The reinforced concrete surface, which has been prepared, cleaned and repaired and provides minimum humidity conditions, is ready for epoxy primer application. Like other materials to be used in the application, epoxy primer will be solvent-free. While preparing the epoxy material, first component A (epoxy resin) will be mixed with a low-speed mixer, while the mixing process is continued, component B (epoxy hardener) will be added slowly and the mixing process will continue until the material becomes homogeneous. Material consumption will be 300-500 gr / m² depending on the surface conditions and the system to be applied. Solvent-free epoxy primer can be applied to the surface with or without a roller or trowel. This is also determined by the self leveling epoxy system to be applied. In the same way, silica or quartz filler can be sprinkled on it, depending on the system chosen.Epoxy primer; It penetrates into the concrete, fills the voids, increases the impact and chemical resistance of the surface, adheres to the reinforced concrete surface with a very high resistance. It enables the coating to be integrated with the reinforced concrete surface by adhering to the layers that come after it.

Mezzanine Application:

Solvent-free epoxy primer applied surfaces will be protected from moisture, dust and air flow and will not be opened to pedestrian or vehicle traffic. Depending on the weather and ambient temperature, a solvent-free epoxy intermediate coat will be applied on it 8-24 hours after the primer application. If filler is sprinkled on it before application, excess filler will be removed with the help of industrial brooms. While preparing the intermediate layer material, component A (epoxy resin) will first be mixed with a low-speed mixer, while the mixing process continues, component B (epoxy hardener) will be added slowly. After the material becomes homogeneous, component C (silica-quartz filler) will be added slowly. After mixing for about 3 more minutes, intermediate coat application will be started. Epoxy intermediate coat will be applied in the desired color and with a trowel.According to the selected self leveling epoxy coating system, silica – quartz filler can be sprinkled on it.

Self Leveling Epoxy Coating Topcoat Application:

Solvent-free epoxy interlayer applied surfaces will be protected from moisture, dust and air flow and will not be opened to vehicle or pedestrian traffic in any way. Depending on the weather and ambient temperature, solvent-free self-leveling epoxy coating material will be applied on it 8-24 hours after the intermediate layer application. While preparing the epoxy self leveling top coat material, component A (epoxy resin) will be mixed with a low-speed mixer, and while the mixing process continues, component B (epoxy hardener) will be added slowly. After the material becomes homogeneous, component C (silica-quartz filler) will be added slowly. After mixing for about 3 more minutes, intermediate coat application will be started. Self leveling epoxy coating, in desired color,It will be applied with a notched trowel or level comb and air bubbles will be removed with a spiked roller. Material consumption will vary depending on the determined system. When the application is finished, a smooth, very smooth and shiny surface will be obtained. Depending on the weather and ambient temperature, the surface can be opened to pedestrian traffic within 48 hours.
