Product description

Fescon LB 7 is a chemically drying floor concrete with a special cement binder for dry, humid and wet areas.

 

  • pumpable
  • rapid strength gaining
  • For layer thicknesses 10-150 mm
  • good workability characteristics
  • rapid drying
  • a surface that can be waterproofed in one work stage
  • fibre-reinforced

Applications

  • Concrete floor casting
  • repair of indoor concrete structures
  • casting of structures that must be taken into use rapidly
  • casting of surface flooring, floors with underfloor heating
  • wet areas, underneath the waterproofing

Instructions

Base
  • Clean, solid and dust-free
  • Sufficient strength, load-bearing capacity and immobility
  • Relative humidity < 95 % RH
  • Temperature > +10 oC
  • loose layers, cement paste and other impurities must be mechanically removed
  • For thin layers, we recommend brushing the product on the base for surface casting.
 
Priming
  • In floor surface casting, carry out the priming in accordance with Fescon Adhesive Primer instructions, depending on the base
  • When beginning casting work, there must be no puddles of primer
Instructions for use
  • Mix a bag (20 kg) of the levelling compound in around 3.0 litres of cold water
  • Mix the levelling compound into a consistent paste using a drill paddle or a concrete mixer
  • Apply the levelling compound with a steel trowel onto the levelled surface
  • Workable for over one hour after adding water
  • Wash tools with water immediately after completing the work
  • Remove dried levelling compound mechanically
Flooring
  • Can be covered using ceramic tiles, plastic or textile mats, vinyl tiles, wood parquet or cork
  • Can also be painted or epoxy coated. However, you must ensure that the technical specifications of the compound meet the flooring manufacturer’s requirements for the base.
  • In wet areas, use the products of the certified Fescon waterproofing system for tiling work. Can be waterproofed after around 3-7 days (+20 °C RH 50%). The moisture content of the entire structure affects the drying time.
  • The need for aftercare is considered on a case-by-case basis according to the purpose of use and drying
    conditions. Aftercare either by covering with a plastic film or using the Fescon curing compound; do not spray with water.
 
Other considerations
  • surface area cast in one go is <15 m2. We do not recommend leaving the casting surface without coating.
