Product description

Double layer plaster of category 0-III – the plaster consists of two layers: the “initial scratch coat” and the “surface floating coat” (it can be additionally covered with a finishing coat layer made of white, cement - based ATLAS REKORD finishing coat).
Suitable for manual and machine application – the mix is available in two versions: for manual or machine plastering (packages additionally marked with letter M).

Main properties

    - for plastering of walls made of ceramic, silicate brick, cellular concrete, concrete hollow blocks - increased bonding - plasticized, easy to apply - layer thickness 6-30 mm - plastering of walls and ceilings

Main parameters

  • layer thickness: 6 - 30 mm
  • consumption: 25 kg/ 1.3-1.4 m²/ 10 mm thickness

ATLAS PLASTERING MIX is manufactured as a dry mix of high quality cement binder, quartz fillers and improvers.
High compressive strength: category CS II (1,5 ÷ 5,0 N/mm²).
Mortar can be supplemented with anti-frost agents for application in low temperature, below +5°C – extended range of mortar application temperature, the method of application (especially adjustment of mix water) and mortar setting conditions must be set according to the guidelines of the additive manufacturer. The amount of the anti-frost agent depends on the content of cement in the mortar – the ratio cement/fillers in ATLAS PLASTERING MIX is 1:4.
Caution. The manufacturer of the mortar does not bear responsibility for the result and the quality of the anti-frost agents used.

Substrate preparation

The substrate should be dry, stable, even and structurally sound, i.e. strong enough, free from layers, which would impair the mortar bonding, in particular dust, dirt, lime, oil, grease, wax, remains of anti-adhesion agents and paints. Hook off poorly bonded elements and remove loosened layers with a steel brush. Edges of joints between cement chipboards should be reinforced with strips of stainless steel mesh. Protect the corners and edges of window and door reveals with galvanized steel profiles. If necessary, use ATLAS UNI-GRUNT priming emulsion to reduce substrate excessive absorption.


Mortar preparation

Pour the mortar from the bag into a clean container with the suitable amount of water (see Technical Data for ratio) and mix using a mixer with a drill (or in cement mixer) until homogenous. Leave the mortar to rest for 5 minutes and remix. The mortar is ready to use directly after mixing and should be used up within approx. 4 hours.


Plaster application

Apply the plaster in two coats. In order to obtain even surface, use plastering beads which are installed mechanically or embedded in the mortar (mesh beads). The first phase is application of the base coat. When the first coat initially sets (but not hardens completely), apply the finish coat. In both stages, the plaster should be applied evenly with a trowel. Collect excess of mortar with a polystyrene or wooden float and put back into the container. Fresh surface can be levelled with a feather edge supported on the plastering beads.


Plaster floating

Time of floating has to be determined experimentally in order to avoid excessive plaster drying. Floating is usually carried out after application of an additional thin mortar coat, corresponding to the mortar grain size. Finishing works must be carried out in accordance to the plastering technology, with tools suitable for the expected finish effect and the intended use of plaster. If plaster is the substrate for ceramic cladding, it should be coarsely finished or not floated at all. When plaster is to be coated with gypsum top finish, it should be floated with polystyrene float.



Ensure appropriate room ventilation during drying. Protect plasters applied out-doors from drying too quickly, e.g. by sprinkling them with water.



Plasters can be painted with any façade paints (e.g. ATLAS SALTA, ATLAS SALTA S, ATLAS SALTA E, ATLAS SALTA N or ATLAS SALTA N PLUS). Painting is possible 2 ÷ 6 weeks after the completion of plaster application (depending on the type and colour of the paint). Painting with ATLAS SALTA S can  start  just  when  the  plaster  dries, not earlier than after three days.

• Adjust the ratio of added water experimentally, following the desired consistency of the mortar, type of substrate and weather conditions. Inappropriate amount of water for mix preparation results in deterioration of strength parameters of the plaster.

• Tools must be cleaned with clean water directly after use. Difficult to remove residues of the set mortar can be removed with the ATLAS SZOP agent.

• Irritant - contains cement. Irritating to respiratory system and skin. Risk of serious damage to eyes. May cause sensitisation by skin contact. Due to its form - powder, the product may cause mechanical irritation of eyes and respiratory system. Keep out of reach of children. Do not breathe dust. In case of contact with eyes, rinse immediately with plenty of water and seek medical advice. Wear suitable protective clothing, gloves and eye/face protection. If swallowed, seek medical advice immediately and show the container or label. Follow the instructions in the Material Safety Data Sheet.

• Content of soluble chromium (VI) in ready-to-use mix - ≤ 0.0002%.
