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 substrate absorption and climatic conditions: masonry and absorbent substrates need to be thoroughly moistened and provided with a "false contact bridge" to spray the Cemix 4612. (consumption as a spray - approx. 3.2 Kg/m2) Provide Cemix 4610 clay joint bridge on concrete and material transitions. Where applicable, modify non-standard substrates by a suitable method to achieve the required properties. Dampen bricks for masonry thoroughly. The substrate shall 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 to a homogeneous, lump-free mixture.
Water demand
| Quantity | Liters (Min) | Liters (Max) |
|---|---|---|
| 1 kg | 0.28 L | 0.32 L |
| 25 kg | 7,00 l | 8,00 l |
Processing instructions
Apply the plaster on the moistened surface with a trowel or other suitable tool. Then roughly flatten the surface with a squeegee to the desired level. After the plaster has set, level the surface with a trowel to the desired flatness. A minimum curing time of 1 day per 1 mm of applied layer is considered. The plaster forms a base and levelling layer for the stucco or final finish.
