4 : 1 (component A : component B) by weight. The components are packaged into doses of the right size and ready to mix. The components must be mixed until a homogeneous mixture is achieved. In order to ensure good mixing, use a mechanical mixer (less than 400 RPM). Use a mixing container; do not spread from the delivery package.
Clean the old concrete surfaces of loose dust, dirt, grease and oil stains. Remove old, flaking coatings and paints, for example by sand blasting, grinding or milling. If the concrete surface is damaged, remove concrete until you reach healthy concrete. Open any cracks with an angle grinder. Patch any resulting cavities and open cracks and correct the grading of balconies using Fescon Repairing Plaster, grain size 3.0 mm or 1.2 mm depending on the layer thickness in accordance with the product sheet. Prime the base with Fescon 2-K Primer; if necessary, you can use oven-dried quartz sand as filler.
Remove the cement paste layer from new concrete surfaces and vacuum the grinding dust carefully. If necessary, patch up the cavities and holes and overlay the surface as above before priming.
The treated surface must be dry, clean, structurally solid and primed with 2-K Primer. The temperature must be between + 5°C and + 25°C and the relative humidity below 85%. Do not work in direct sunlight. Prime with Fescon 2-K Primer. Mix the Primer well with a power mixer and apply it on the base with a roller or trowel. Prime very porous bases twice. The primer must be applied in such a manner that the surface film is continuous and there are no pores in the surface. The concrete must have a strength of over 20 MPa and must be at least four weeks old before priming. The base must be solid, dry, and free of dust and grease. If necessary, use mechanical cleaning methods and tools.
The use of a primer is recommended to provide alkali protection and ensure good adhesion.
Concrete, cement levelling compound:
2-K PRIMER (0.15-0.3 kg/m²)
POX 5001 (0.15-0.3 kg/m²)
In order to guarantee optimal adhesion, spread oven-dried quartz sand on top of the primer layer.
Allow the primer to dry before coating. Apply the coating within 6 to 24 hours of priming.
Spread the 2-K ELASTIC with a smooth or toothed trowel in layers at least 2 mm thick = 3 kg/m². 2-K ELASTIC must be aerated with a spiked roller. The corners and edges can be reinforced with strengthening membrane or equivalent. For reasons of appearance or to prevent the surface from being slippery, colour flakes can be sprinkled on top of the wet coating. If you wish the finish to be slicker and more dirt-resistant, you can apply Fescon Protective Lacquer.
Wash tools with a solvent immediately after use, for example with Fescon Thinner.
There are separate maintenance instructions for the product.
Load from sharp furniture or grates can cause indentations in the surface.
Hardened product and empty, dry packages can be delivered to a landfill. A liquid product must be delivered to a hazardous waste reception point.
