The surface must be clean, dry, level, load-bearing, and prepared in accordance with the applicable substrate requirements.
Contaminants and substances that may negatively affect adhesion must be removed. Uneven areas and chips should be repaired using suitable materials, such as “Klebe-und ArmierungsMasse AM 195”. Highly absorbent substrates should be primed with products such as “UniGrund” fixing primer or “GrundKonzentrat” primer concentrate.
To achieve a uniform visual appearance and improve adhesion on prepared substrates, including glossy surfaces such as cast-in-place concrete, it is recommended to use “PutzGrund 118” primer tinted to match the plaster color.
Material Preparation
“AirFront” is a ready-to-use water-based dispersion plaster. Thoroughly mix the contents of the container using a low-speed mixer before application. Tinting should be carried out according to the “AIR” color chart by Elf Decor.
After adding “AirGraines” granules, the plaster must be mixed again thoroughly.
If necessary, the material may be diluted with water to adjust its consistency, but not exceeding 10% by weight. Water must be added in equal amounts to each bucket to avoid color variations.
Application
The material is applied using a pneumatic texture spray gun equipped with a hopper of suitable capacity. The recommended nozzle size is 2–3 mm, and the recommended compressor pressure is 2.0–2.5 bar.
To achieve a smooth finish, the applied surface should be smoothed with a rigid plastic float.
Manual application is also possible.
Application Method
“AirFront” is applied in a single coat using a pneumatic spray gun from a distance of 0.3–0.5 m from the surface, using uniform movements in the chosen direction: vertical, horizontal, or circular.
The choice of equipment and nozzle size determines the final surface texture. To ensure a uniform texture, adjoining surfaces should be applied by the same crew to avoid differences caused by individual application techniques.
To prevent visible overlaps, a sufficient number of workers should be assigned to each area. The material should be applied continuously and without interruption using the “wet-on-wet” technique.
Due to the use of natural granite aggregates, slight color variations may occur. Therefore, adjoining surfaces should be coated with material from the same batch number, or materials from different batches should be pre-mixed before application.
