Product Description

Remmers Betofix Filler is a factory mixed, mineral, dry mortar that is ready to use after mixing with water. The very smooth material hardens with little shrinkage and crack-free.

Best Uses

Remmers Betofix Filler is a PCC fine filler best used for structural repair of concrete structures. Polymer additives improve adhesion of the mortar, making it especially suitable for vertical and over-head work. The hardened mortar is resistant to water, weather, frost and frost/de-icing salt.

  • Scratch coat and levelling filler for use indoors and outdoors
  • Partial and full surface levelling of concrete surfaces
  • Coating prefab elements, masonry work and mineral surfaces
  • Repairing holes, cracks, voids, missing and broken out areas
  • Can be used indoors and outdoors, in wet and under water areas


At the time of application the substrate must be matt damp, sound and load-bearing. Remove loose material that could interfere with adhesion and cement grout e.g. by blasting. The substrate must also be sufficiently rough. The pull-off strength of the substrate must correspond to the relevant technical rules. The pre-wet substrate should be still slightly absorbent.

Pour approx. 3.8 l of water into a clean container (mortar tub), then add 25 kg Betofix Filler. Mix thoroughly with a mixer/positive mixer for approx. 2 minutes until homogeneous and until the proper consistence for working has been achieved. If necessary, a little more water may be added. Mixing by hand as well as the preparation of partial amounts is not permissible. To achieve the best possible adhesion between the concrete and filler, a scratch coat should be applied to the matt amp substrate first. The filler can be applied in a single layer from 1 - 6 mm thick and in broken out areas up to 10 mm.

Initially set mortar cannot be made workable again by adding water or fresh mortar. Do not use if the temperature of the air, substrate and building material is below +5 °C or above +30 °C. Low temperatures lengthen, high temperatures reduce working and setting time.

Protect the fresh mortar surface for at least 4 days from weather influences such as sun, wind, rain, drafts and frost to and from too fast dehydration.
