Field of application

Field of application
  • Repair of concrete construction components with a rough surface that are positioned horizontally or at a gentle slant
  • Bonded screed, floating screed and screed on separating layer
  • Heated screeds
  • Load-bearing layer underneath reactive resin coatings
  • Base layer under Remmers Crete coatings
  • Interior and exterior use

Properties

  • High mechanical resistance
  • Fast curing
  • Low shrinkage
  • Low-stress and crack-free setting
  • Can be applied by machine
  • Screed according to DIN EN 13813: CT - C40 - F6 - A7 - B1.5
  • Substrate requirements: The substrate must be firm, dimensionally stable, capable of bearing loads and free of loose constituents, dust, oil, grease, rubber marks and other substances that could interfere with adhesion. The tensile strength of the surface of the substrate must be at least 1.5 N/mm² on average (smallest individual value of at least 1.0 N/mm²), and the compressive strength must be at least 25 N/mm².
ApplicationApplication
  • Application time::(+20 °C): approx. 30 minutes Layer thickness Single layer thickness < 80 mm Layer thickness in breakouts up to max. 100 mm In the case of bonded screeds, apply the product while the bonding layer is still wet. Subsequent processing Protect fresh mortar surfaces from wind, direct sunlight, rain and/or frost for at least 3 days so that they do not dry too quickly. Machine working Please contact Remmers Technical Service (phone +49 5432 83900) before applying with machine processing.
Working tools / cleaning
  • Mixing tool, trowel, aluminium rule, smoothing trowel, power trowel Clean tools with water while the material is still fresh.
Storage / shelf lifeStorage / shelf life
  • If stored in an unopened container and in a dry place, the product will keep for approx. 12 months.
Usage
  • Approx. 2.0 kg/m²/mm coating thickness, or approx. 2.0 kg/dm³
  • 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. Do not dispose of together with household waste. Do not allow to enter the sewage system. Do not empty into drains.
