What requirements must the substrate meet to be able to install parquet?
- The substrate must be horizontal and sufficiently flat. Flatness can be improved by levelling with DL (Maxi) Egaline.
- The substrate must be sufficiently dry. If necessary, a moisture barrier can be applied with Hydroblocker 2K or Hydroblocker 3K.
- The substrate must be sufficiently strong with good surface cohesion. A primer such as Primer WB, Primer PU Turbo and Hydroblocker 2K can improve the surface condition in some cases. Cracks in the screed can be repaired with a synthetic repair mortar (Hydroblocker 2K + sand).
- Smooth substrates such as ceramic tiles and polished concrete must be properly degreased and scratched.
- If the parquet is installed on underfloor heating, this must be switched off at least 48 hours before gluing.
