Processing details
Learn more about technical details for processing this product.
Substrate requirement
The substrate must comply with the applicable standards, must be solid, free of loose particles, free of dust, paint, residues of demoulding products and efflorescence. It must be sufficiently rough, dry and evenly absorbent. The surface shall not be frozen or water-repellent. The substrate shall be stable in volume.
Substrate preparation
Depending on the absorbency of the substrate and the climatic conditions, it needs to be moistened. Apply Lime spray on the old substrate. If necessary, modify non-standard substrates by a suitable method to achieve the desired properties. Smooth unevenness of substrate with suitable Cemix materials and allow to dry and cure. The substrate shall comply with applicable codes, 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 drum mixer or 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 trowel or other suitable tool. Then roughly flatten the surface with a feather edge or lath or trowel to the required level. After the plaster has set, trowel the surface to the desired flatness. The minimum curing time of the core plaster is considered to be 1 day per 1 mm of applied layer. The plaster forms a base and levelling layer for the stucco plaster with a paint finish.
