FOR PLASTERWORK CATEGORY 0 TO III

FOR INTERNAL USE

USE

ATLAS LIGHT CEMENT-LIME MACHINE-APPLIED PLASTER is a machine-installed material for traditional plasterwork in categories 0 to III. It can also be applied by hand. The material can be used on walls and ceilings, indoors – for renders or base coats to be painted, for setting coats and other coats. The substrate may consist of unfinished brick, concrete blocks, hollow blocks and other similar ceramic and lime-sand materials. The product can also be used on concrete, aerated concrete, cement-bonded particleboard, also on cement and cement-lime plaster or gypsum substrates. Applied in layers of 5-30 mm.

PROPERTIES

ATLAS LIGHT CEMENT-LIME MACHINE-APPLIED PLASTER is a ready-to-use dry mix formulated on the basis of top quality cement binder, lime, quartz fillers, perlite and additives. Machine application guarantees high efficiency of work, and the appropriately developed application properties make the material easy to use and workable.

SUBSTRATE PREPARATION

The substrate should be dry, stable, even and sound, free of materials that might reduce adhesion, especially dust, dirt, lime, oil, grease, wax, residues of release agents and paints. Insufficiently bound substrate fragments should be knocked off, whereas all loose or crumbling particles should be removed using a steel wire brush. Gypsum substrate should be scratched with a sharp chisel to make a diagonal network of scratches, ca. 3 mm deep. Contacting edges of cement-bonded particleboards should be reinforced with stainless steel reinforcing mesh strips. Corners and edges around window openings and doorways should be reinforced with galvanised steel profiles. If the water absorption of the substrate needs to be reduced, it is advisable to use ATLAS UNI-GRUNT primer emulsion. Directly before plastering the substrate may be wet with clean water. The next step is to apply an initial scratch coat. The material should not be used on wood, metal and plastic substrates.

APPLICATION

The material is loaded into a plastering machine adapted for work with ready mixes. The material is applied to walls using a spray gun, in overlapping horizontal strips, from top to bottom. The sprayer nozzle should be guided in a smooth motion, at a constant distance from the surface. If the manual method is used, the material should be applied with a trowel. Even out the material using an H-shaped plastering rule and leave to until the plaster begins to set. Fresh plaster can be smoothed with a long feather edge until a flat surface is obtained. The moment when floating should commence should be determined by trial and error, making sure that the plaster surface does not dry excessively. Floating is usually done after an additional thin coat of material is applied, at thickness corresponding to the grain size. Finishing work should be done in accordance with plastering techniques, using tools appropriate to the desired finish and the planned further treatment of the plaster. If the plaster has been planned as a substrate for ceramic tiles, it should not be finished, only floated if necessary. If the plaster surface is to receive a setting coat, it should be floated with an EPS float. While the material is drying, the rooms should be well ventilated. The above information constitutes basic guidelines on product use and does not relieve users of the obligation to work in accordance with good practice and health and safety regulations.

CONSUMPTION

The average material consumption is ca. 11 kg for 1 m2, at 10 mm layer thickness.

TOOLS

Plastering machine, trowel, EPS float and wooden float, H-shaped plastering rule, long feather edge. The tools should be washed with clean water directly after use. Persistent residues of hardened material can be removed using ATLAS SZOP.
