Substrates must be dry, absorbent, level, sound, free of dust, loose particles, paint, wax, oil, rust, and traces of gypsum.
The moisture content of the screed must be lower than the maximum prescribed by the timber manufacturer.
Check moisture throughout the entire thickness of substrates, using carbide hygrometer.
Floating screeds over insulation or light weight layers (e.g. light weight concrete) and slabs on grade must be provided with a moisture barrier to prevent rising damp.
To repair cracks in the substrate, consolidate screeds and level uneven screeds.
