product_code:REAL 620

Description:

Three-component, hybrid, self-leveling concrete is a floor coating developed by combining epoxy resin and specially formulated powdered chemical components. Combines mechanical strength with high adhesion, elasticity, chemical resistance and protection of concrete surfaces, providing a high-quality floor coating. It is applied to previously cleaned, sound concrete substrates. It can be used both as a primer and a finish coat, without the need for prior priming of the substrate. It can be applied to concrete surfaces with a humidity of up to 30%.

AREA OF APPLICATION

The hybrid, self-leveling epoxy concrete is suitable for floors in factories and warehouses, in industrial areas such as workshops, production and logistics rooms, for floors in parking lots and garages, as well as for industrial flooring exposed to water and chemicals.

SURFACE PREPARATION
The surface to which the product will be applied must be completely cleaned of dust, grease and other contaminants to ensure a sound and clean base. In the presence of old rust coatings, unstable or crumbling surfaces, these must be removed by cleaning. The rust is mechanically cleaned with a diamond-tipped machine according to the SA 2½ standard, after which the dust generated from the cleaning must be cleaned with an industrial vacuum cleaner. If there are cracks or irregularities on the application surface, they must be filled with GR 900 repair mortar to ensure a smooth and even application surface.

PRODUCT USE
Before application, REAL 620 HYBRID hybrid concrete, components A and B, are first mixed separately, then mixed and stirred with a mixer at low speed until a homogeneous mixture is achieved, then component C is gradually added until a homogeneous mixture without lumps is obtained. It is applied to previously prepared, sound, dry and clean surfaces.

APPLICATION METHOD
First layer of hybrid concrete:
It is applied evenly using a steel trowel, as this layer serves as a filling layer for cracks or irregularities on the surface. The approximate consumption for this layer is 0.5 kg/sq.m.

Second layer (base) hybrid concrete:
After the first layer has dried, the hybrid concrete is applied evenly to the floor with a 4 mm notched steel trowel. The consumption for applying the second layer is approximately 4.5 kg/m2.

Hardening and drying time:
24 hours after application, the floor is ready for pedestrian traffic, and for heavier traffic after 48 hours at a temperature of +20°C. At lower temperatures, the hardening and drying time may increase.
