  • Remove as much old paint and loose plaster as possible. Dilute sealing primer 1: 1 with pure water and apply saturating with the spray pump on a clean, receptive and stable surface.
  • Mix the required amount of polymer cement for the first layer (1 kg per 1.2 m²) with pure water. Mixing ratio 400 ml water per kg. Mix with a slowly rotating mixer (500 rpm) to a thick liquid, lump-free mass and let it rest for 2 minutes. Stir again before use. The mixture can be processed for 35 to 45 minutes depending the ambient temperature. (when stiffening in the pot, never add water to respect the mixing ratio: mix as much product as you can apply within the processing time.
  • Apply the first coat of +/- 1 mm vigorously to the still wet primer using a wide, stiff brush.
  • Allow to dry for 3 to 5 hours before applying the second coat (the first one should feel cured).Moisten the first coat with water using a nebulizer and apply the second coat of +/- 1 mm perpendicular to the brush direction of the first coat.

Immediately clean material and spilled product with clear water. After curing only mechanically removable. Full cure after 7 to 14 days, depending on the temperature. Humidity during that period: 50 to 80%. Provide ventilation to avoid condensation. Do not use a construction dryer or dehumidifier in the first month after application. Recoatable after curing with breathable paint. Consumption: 1 bag of 10 kg for 6 m² (2 mm thick in 2 layers on a smooth wall).
