Mosaic plaster AL90 is intended for indoor and outdoor decorative finishing of the buildings surfaces. It is used on all even mineral substrates, such as: concrete, foam, haydite compression, plastered base, gypsum, gypsum plasterboard, chipboard, etc. It is especially effective when used in the bonded insulation systems. The plaster possesses resistance to alkaline attack.
Instructions for use
The surface should be smooth, clean and dry, without grease, oils, waxes and other materials reducing adhesion, as well as, without visible destruction, cavities and recesses. Old remains of paint layers must be removed. Plaster bases, gypsum plasterboards, wood chipboards should be pre-treated with primer GL25. Old and porous surfaces previously have to be treated with primer GL27. In case of fungus or mould on the affected areas, they have to be treated with the antibacterial primer. Before applying the decoration plaster, the surface has to be primed with priming paint GL33. The decorative plaster is applied only after the complete drying of GL33. The filler of the plaster is a natural material and the shade of different buckets may vary, therefore the required number of buckets must be mixed for one surface. Before applying, decorative plaster AL90 should be mixed thoroughly to a smooth paste. Decorative plaster is applied on the prepared substrate with a stainless smoothing-trowel at an angle of 60 degrees. The thickness of the layer must match the double size of the grains. Surplus plaster is removed and mixed in a bucket. The surface is trowelled with a stainless smoothing-trowel. Decorative plaster is applied by “wet on wet” method, not allowing the surface to dry out before applying the next layer. Work on the same flat area should be carried out continuously.
During the works and material’s drying-out, the plastered surface must be protected from direct sunlight, rain and strong winds. You may not use rusty tools and containers. Material must not be mixed with other plasters and paints. Finishing work, the tools have to be washed immediately with plenty of water. Hardened plaster can be removed only by mechanical means.
Terms of application and storage
Work should be carried out at substrate temperatures from +50 C to +300 C. It should be stored in an original container, in areas with a constant temperature of +50 C to +250 C. During transportation it has to be protected from freezing. Storage period is 24 months from the manufacture date indicated on the package.
Instructions for disposal
The material cannot be sewered into drains and discharged into wastewater. Plastic packaging is recommended to recycle in special containers for plastic. Material residues after drying can be disposed as construction waste or household garbage.
Security measures
Keep out of reach of children. In case of eye contact, rinse immediately with plenty of water and consult a doctor for medical advice.
