Substrate requirement
The substrate must comply with the applicable standards, must be solid, free of loose particles, free of dust, paint, residues of demoulding substances and efflorescence. It must be sufficiently rough, dry and evenly absorbent. The surface shall not be frozen or water-repellent. The substrate must be stable in volume.
Substrate preparation
A bonded layer: Before applying the screed to the old concrete, the substrate must be moistened and treated with Cemix contact bridge 1500.
Floating layer: Separate the substrate with a suitable separation layer e.g. PE 0.2mm. Thermal and acoustic insulators must be stacked together without gaps. Working or structural joints must be respected and must be created perimeter dilatation of vertical building elements (walls, pillars, pipes, etc.). The substrate must comply with the applicable regulations, standards or recommendations of the material manufacturer.
Preparation of the mixture
Prepare the material by pouring the dry mixture into the prescribed amount of water and mixing it. Use potable water or water complying with EN 1008 to mix the mixture. Mix using a slow speed propeller mixer. Mix to a homogeneous, lump-free mixture and leave to rest. Then mix again briefly. Use suitable machinery when processing by machine.

Processing instructions
Spread the mass on the prepared substrate and compact it, e.g. with the strokes of a trowel. Then flatten the surface with a lath and smooth it with a plastic or steel trowel. An advantage is the possibility of pulling down with a vibrating lath.
