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 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. Spray the substrate with lime pre-sprinkler Cemix. 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 with the prescribed amount of water.

Mixing
Processing instructions
Apply the plaster to the surface with a trowel or other suitable tool. Then roughly flatten the surface with a squeegee to the desired level. Once the plaster has set, open the plaster flat with a suitable tool. A minimum curing time of 2 days per 1 mm of applied layer is considered. The plaster forms a base and levelling layer for the stucco or final finish. The plaster must not be left untreated in the exterior for long periods (especially over the winter period).

Treatment after application
Non-absorbent materials prolong the maturation period.
After application, the direct negative effects of sun, heat, humidity and draughts should be avoided. Protect from frost and rain. Direct heating of the surface is prohibited.
Tool and cleaning instructions
Wash off tools with water immediately after finishing work. Clean dried residues mechanically.
