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
Depending on the absorbency of the substrate and the climatic conditions, it needs to be moistened. Coat the substrate with Cemix remediation underlay. If necessary, treat non-standard substrates with a suitable method to achieve the desired properties. The substrate must comply with applicable regulations, standards or material manufacturer's recommendations.
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.

Mixing
Processing instructions
Apply the plaster to the surface with a stainless steel trowel or other suitable tool. Level it to the desired level in a min. layer thickness. After the material has tightened and is pressure-resistant, smooth the surface with a felt and then with a foam trowel while sprinkling with water. (for a uniform surface appearance). The plaster forms a base layer for Cemix coatings.
