Instructions
Preparation:
The concrete substrate must be clean and free of dust, damaged concrete, grease or other contaminants that may impair
adhesion. Substrate with a roughened and raw surface with closely spaced irregularities provide better adhesion. Clean the
substrate carefully and if possible pre-water 24 hours before casting. Remove free water just before casting.
Mixing:
R50 is mixed for at least 5 minutes to a lump-free mass. The mixing takes place with a concrete mixer. Vary the water content
according to the desired consistency. However, no more water than is specified in the technical data. The concrete mass
must have a temperature of approx. 20 °C. Compensate cold dry use with warm water and vice versa.
Application advice:
The mortar is best applied with a steel trowel or trowel in layers up to 50 mm. The surface can then be felted or smoothed to
achieve the desired surface structure.
After treatment:
Semi-hardened material can be adjusted with a trowel. Free and unprotected surfaces are protected immediately after casting so that shrinkage and dehydration cracks do not occur. After casting, the surface can be moisture-cured with a thin, light mist of
water, but that cannot mechanically damage the mortar. At air temperatures above 5°C, curing may take place with remaining
form, covering or supply of water and may last the entire first week. As soon as the surface hardens, it can be watered and
covered
