Product description

Fescon Flow H is a low-alkali (pH < 11), casein-free, pump-applied levelling compound with a special cement binding agent, that is easy to level and features excellent workability.

 

  • Easy to level
  • For layer thicknesses 4 - 30 mm
  • Dries through hydration.
  • Can be pump-applied

Applications

  • For finishing concrete floors in flats, offices, public buildings, schools, hospitals and other such sites

Instructions

Base
  • Clean, solid and dust-free
  • Sufficient strength, load-bearing capacity and immobility
  • Relative humidity < 95% RH
  • Temperature > + 10 °C
  • Loose layers, cement paste and other impurities must be mechanically removed
  • If the adhesion strength of the base is < 0.5 MPa, the floor is constructed as a floating structure using Flow HS
Priming
  • Carry out the priming in accordance with Fescon Adhesive Primer instructions, depending on the base
  • The primer must be dry before levelling
Instructions for use
  • Mix a bag (20 kg) of the levelling compound in 4.0-4.4 litres of cold water
  • Do not use any more water, because this decreases the surface strength
  • Mix the levelling compound carefully and long enough to form a consistent paste
  • Apply the levelling compound with a steel trowel or pump it onto the levelled surface
  • Workable for about half an hour after adding water
  • Wash tools with water immediately after completing the work
  • When pumping, the relative humidity in the air must be >40%
Flooring
  • Can be floored using ceramic tiles, plastic or textile mats, vinyl tiles, wood parquet or cork
  • The floor levelling compound (once it has dried) must not be left uncovered for longer than three months
After treatment
  • Once the base has dried sufficiently for the chosen flooring, the flooring is installed or the aftercare begun
  • In conditions with an RH of less than 40%, special attention should be paid to when to start the aftercare
