QS 30 Quick-hardening floor compound

Product description

Fescon QS 30 is a floor compound with special cement binder and has an extremely rapid strength gain The maximum grain size is 1.2 mm. Reasonably pliable, fills the casting space better, and is therefore an excellent choice for underfloor heating applications.

  • extremely rapid strength gaining
  • rapid drying
  • for layer thicknesses 5-300 mm
  • a surface that can be waterproofed in one work stage


 

Applications

  • casting, straightening and filling indoor concrete floors
  • repair of indoor concrete structures
  • castings where the structure must be usable or coated quickly
  • casting of surface flooring
  • wet areas, underneath the waterproofing

Instructions

Base
  • sufficient strength, load-bearing capacity and immobility
  • clean, solid and dust-free
  • Remove cement paste and loose layers from the concrete surfaces
  • Temperature >+10 oC and relative humidity <95% RH
Priming
  • Carry out the priming in accordance with Fescon Adhesive Primer instructions
  • When beginning the levelling work, there must be no puddles of primer
Instructions for use
  • Mix a bag of the levelling compound (20 kg) in 2.4-2.6 litres of clean water
  • Mix the QS 30 into a consistent paste using a drill paddle
  • Spread the compound onto the base and level or float it with a steel trowel. Perform the spreading, levelling and floating at the same time; if compacting is required, use vibration.
  • Workable for about half an hour after adding water
  • Wash tools with water immediately after completing the work
  • Remove dried compound mechanically
  • The floor must be built as a floating, reinforced structure if the base is weak concrete (adhesion strength < 0.5 MPa), wood, or insulation.
Covering
  • Can be covered using ceramic tiles, plastic or textile mats, vinyl tiles, wood parquet or cork
  • We do not recommend leaving the floor compound without coating
Waste handling

Hardened product and empty, dry packages can be delivered to a landfill. A liquid product must be delivered to a hazardous waste reception point.
