Instructions

Old concrete surfaces

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, or Overlaying Plaster, depending on the layer thickness.

New concrete surfaces

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. The concrete must have a strength of over 20 MPa and must be at least four weeks old before priming.

The treated surface must be dry, clean and structurally sound. The temperature must be between + 5°C and + 25°C and the relative humidity below 80%. The moisture content of the base must be below 90% relative humidity. Measure with a surface moisture meter. Mix carefully with a power mixer before use (less than 400 RPM). Use a mixing container; do not spread from the delivery package. The mixed product must be used within 30 minutes.

Spread the well-mixed Fescon 2-K Primer with a trowel or an airless sprayer onto the base so that the base becomes saturated. 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 primed areas must be coated within 6-24 hours; if necessary, the primer can be sanded while fresh with clean, oven-dried quartz sand. In humid conditions, you must ensure sufficient ventilation. Wash tools with a suitable solvent immediately after use, for example with Fescon Thinner.

Waste handling

Hardened product and empty, dry packages can be delivered to a landfill. A liquid product must be delivered to a hazardous waste reception point.
