AT 391 Natural mosaic plaster 1.2 - 2.5 mm

For decorative thin-coat internal and external plaster coating. The product contains a mixture of fine natural or coloured aggregates and acrylic binder. It is especially recommended for finishing walls in high foot traffic areas, such as staircases, hallways and corridors, as well as on building facades, plinths, pilasters and cornices. Available colours according to ALPOL MOSAIC chart (pallets: MILOS, KOMODO).

Substrate type
Cement and cement lime plaster, concrete surfaces, cement finish, plasterboard, reinforcing layer in EPS-based insulation systems.

Substrate preparation
The substrate should be even, smooth, clean, stable, sound and properly cured (putty, cement finish and adhesives at least 3 days from application, plaster coatings after 28 days from application, cured concrete). Remove brittle and loose material of poor adhesion, patch chipped areas with ALPOL AZ 130 quick-setting mortar or ALPOL AZ 135 levelling mortar. Treat loose or absorbing substrates with ALPOL AG 700 deep-penetrating primer. Even out all surface irregularities using e.g. ALPOL AK 531 or ALPOL AK 532 insulation adhesive. On larger irregularities, use also ALPOL SW 145 fibreglass reinforcing mesh. Possible substrate unevenness may result in uneven aggregate distribution on the surface and, as a result, produce uneven colour. At least 12 hours before planned plaster application, thoroughly treat the substrate with ALPOL AG 705 primer stained to match the colour of the decorative plaster. Fine-grained patterns in dark colours on large continuous surfaces are not advisable. In all cases, in order to obtain the desired visual effect, it is recommended to divide the surface into smaller sections, e.g. imitating bricks, slabs or stone blocks, using painting tapes or ALPOL self-adhesive templates that are glued to the primed substrate. In order to achieve attractive deeper joints that imitate stone slabs, the substrate must be properly pre-treated using a rustic strip.

Low-speed mixer, basket mixer, stainless steel floats and trowels.

Working conditions
Before use, check if the colour and granulation are as ordered. Work in dry conditions, at the ambient and substrate temperatures between +8°C and +25°C as well as relative air humidity below 80%. Do not mix the plaster with other plasters, bonders or filling compounds. Do not thin with water. Avoid working in intense, direct sunlight, strong wind and high air humidity. Protect the plaster work from rain until it fully sets. High air humidity and low temperature can prolong setting time and change the colour shade. If exposed to moisture, “milky mist” may appear. It will disappear when the surface dries out. Therefore, avoid applying the plaster in areas where it will be exposed to contact with water or moisture (e.g. horizontal surfaces or those featured with insufficient inclination, small ponds etc.), and on components which are not properly insulated against moisture (foundations, fencing, or retaining walls).

Storage
In original, not damaged, tightly closed containers in temperature between +8°C and +25°C – shelf life 12 months from production date. Tightly close opened containers and use the remaining contents as soon as possible. Protect the product from freezing and overheating.

Notes
The specifications and instructions for use are based on the temperature of 20(±2)°C and relative air humidity 60(±5)%. Drying and final cure time may vary in different conditions. Contains: post-reaction mixture of 5-chloro-2-methyl-2H-isothiazol-3-one [EC no. 247-500-7] and 2-methyl-2H -isothiazol-3-one [EC no. 220-239-6] (3:1). May cause allergic reaction. Wear safety goggles. In the case of contact with eyes, rinse immediately with plenty of water and seek medical advice. Protect your skin by using protective clothing and gloves. Keep out of the reach of children. Clean fresh stains with water. The manufacturer assumes no liability for damage resulting from unskilful or improper use of the product. For patterns containing natural aggregates, the manufacturer does not guarantee full colour consistency among different batches of plaster.
