    • Preparation
      • Substrate requirements

        Clean, dust-free and capable of supporting a load.

      • Preparations

        Pre-wet the substrate so that it is slightly moist.

    • General information
      • The colour that is obtained after drying and hardening depends on the ambient conditions and the processing method. For instance, a freshly smoothed surface will be lighter than one that is smoothed later or roughened. Different grain sizes of the same product may lead to slight differences in colour. Substrates soaked from the back may cause discolouration.

        The mixing water must be of drinking water quality.

        May contain traces of pyrite (iron sulphide).

        Do not use on gypsum-based substrates.

        Low chromate content in accordance with Directive 2003/53/EC.

        The characteristic data of the product were calculated under laboratory conditions at 20°C and 65% relative humidity.

    • Disposal instructions
      • Larger quantities of leftover product should be disposed of in the original containers in accordance with the applicable regulations. Completely empty, clean containers should be recycled.
