Base

  • The temperature of the substructure must be between +5°C…+25°C
  • The substrate may be a concrete base, insulation board, or the product may be cast directly onto the ground
  • If cast directly onto a concrete base, the surface must be clean, solid, dust-free, and absorbent
  • Any required reinforcement must be installed according to structural drawings
  • If the substrate is weak concrete (tensile strength < 0.5 MPa) or insulation board, the concrete must be cast as a floating, reinforced structure. The floating structure must be separated from the subfloor and vertical structures

Priming

  • The concrete substrate must be moistened to a matt-damp condition before product installation. No free water must be present.
  • Liquid bonding primers are not to be used with this product. 

Mixing and Application

  • Avoid strong wind, direct sunlight, and rain during application.
  • During casting and curing, the air and substrate temperature must be between +5°C and +25°C.
  • One 25 kg bag of dry powder is mixed with 2.5–3.0 litres of clean water. It is recommended to start with the minimum amount of water and add more if needed. Do not exceed the recommended water amount, as this will reduce the strength values, increase the risk of segregation, and prolong drying time.
  • The product is mixed into a uniform mass using a mortar mixer, concrete mixer, or forced-action mixer. Mixing time with mortar or forced-action mixer: approx. 2 minutes, in a concrete mixer: approx. 5 minutes
  • After mixing, allow the mass to rest for approx. 10 minutes, then remix briefly.
  • Working time is approximately 2 hours from mixing.
  • The product is placed into formwork, compacted, and leveled to the correct height. The surface may be finished to the required quality using, for example, a polyurethane float and/or steel trowel, once the material has slightly stiffened.
  • Tools should be cleaned with water immediately after use.

After treatment 

  • Adequate moist curing of the installed product must be ensured during the hardening phase to allow the hydration process to proceed correctly and the desired strength to be achieved. This also helps prevent plastic shrinkage cracking and delamination from the substrate.
  • The surface of the installed product should be kept moist for 2 to 5 days. Moist curing can be carried out depending on conditions and application using fine water misting, plastic sheeting, or Fescon curing compound.
  • Especially in spring, curing must be started immediately and performed carefully, as relative humidity is often below 40% RH. Low relative humidity combined with sunlight and wind causes the surface to dry out very rapidly.

Additional Information

  • Formwork, reinforcement, and casting work must be carried out in accordance with standard practices and the designer’s instructions.
