The surface must be clean, dry, even, sound, and capable of bearing loads, while meeting all substrate preparation 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 smooth and glossy surfaces such as cast-in-place concrete, it is recommended to use “PutzGrund 117” primer tinted to match the plaster color.
Material Preparation
“AirTex” is a ready-to-use 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.
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 1.5–2.5 mm, and the recommended compressor pressure is 1.8–2.2 bar. Equipment with screw-feed or rotor-feed systems may also be used.
To achieve the desired decorative effect, the applied surface may be smoothed with a rigid plastic float or a stainless-steel trowel. Manual application is also possible.
Application Method
“AirTex” 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. For professional application of AirTex on large surfaces, we recommend using specialized air-spray equipment (screw-feed or rotor-feed systems) with a nozzle size of 1.5–2.5 mm (equivalent to the Graco RTX series) or a HOPPER spray gun (compressor pressure: 1.8–2.2 bar).
Dilution with water up to 10% is permitted.
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.
To avoid color differences, it is recommended to use material from the same batch on adjoining surfaces or to pre-mix materials from different batches before application.
