Product description

Smooths the surface of walls – the use of aggregate with a diameter of 0.2 mm makes it possible to obtain a very smooth surface.
Enables smoothing the thin-coat structural plasters – laid on either traditional plasters or on thermal insulation layers (is not an element of thermal insulation systems).
Improves the quality of damaged cement-based and cement-lime plasters and of concrete substrates.

Main properties

  • white cement - based
  • for finishing walls and ceilings
  • for typical mineral substrates
  • contains fine aggregate – up to 0.2 mm
  • reinforced with microfibres

Main parameters

  • compressive strength: 3.5 ÷ 7.5 N/mm²
  • consumption: 1.5 kg/1 m² for 1 mm thickness
  • layer thickness: 1 - 10 mm

USE

Go top

Smoothes the surface of walls – the use of aggregate with a diameter of 0.2 mm makes it possible to obtain a very smooth surface.

Enables smoothing the thin-coat structural plasters – laid on either traditional plasters or on thermal insulation layers (is not an element of thermal insulation systems).

Improves the quality of damaged cement-based and cement-lime plasters and of concrete substrates.

Used as the third smoothing layer for newly applied plasters.

Types of substrates cement and cement-lime plasters, concrete.


PROPERTIES

Go top

White colour – based on white, fine type of cement, perfectly replaces gypsum finishing coats in places where they can be exposed to damage - on external walls and in wet rooms.

Resistant to micro-cracks – it contains special microfibres additionally reinforcing its structure.

Contains hydrophobic agents – they reduce the absorbing capacity of the mortar but do not limit its vapour permeability.

APPLICATION

Go top
Substrate preparation

The substrate should be dry, stable, even and structurally sound i.e. strong enough, free from layers that may weaken mortar adhesion, in particular dust, dirt, lime, oil, grease, wax and remains of oil and emulsion paint. Hammer off poorly adhering elements and remove loose pieces using a steel brush. 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 proportions) and mix using a drill with a mixer (or in cement mixer) until homogenous. Leave the mortar to rest for 5 minutes and then remix. The mortar is ready to use directly after mixing and should be used up within ca. 2 hours.

Plaster application

Apply the mortar evenly with a steel float. Smooth the applied plaster as work progresses. It is recommended to fill in large defects in the substrate before the application of the finishing coat. The surface can be finished by light floating using a felt float or with sand paper after drying. Open time of the mass (between mortar application and floating) depends on substrate absorptivity, ambient temperature and mortar consistency.

Maintenance

For mortar applied indoors, avoid draughts and ensure appropriate room ventilation and airing. Protect external plasters from drying too quickly and precipitation (during and after application).

Painting

Plastered substrates can be painted with any façade paints (e.g. ATLAS ARKOL S, ATLAS ARKOL N, ATLAS FASTEL-NOVA and ATLAS ARKOL E). Commencing painting works is possible after 2 ÷ 6 weeks after the completion of plaster application (depending on the type and colour of the paint). Only painting with ATLAS ARKOL S silicate paint can start after the plaster has set, not earlier, however, than after 48 hours. The application of waterproof insulation of ATLAS WODER type may commence just after 2 days.

CONSUMPTION

Go top

The average consumption is ca. 1.5 kg of mix / 1 m² / 1 mm of layer thickness.

IMPORTANT ADDITIONAL INFORMATION

Go top

• 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%.

TRANSPORT & STORAGE

Go top
The mortar must be transported and stored in tightly sealed bags, in dry conditions (most preferably on pallets). Protect against humidity. Shelf life in conditions as specified is 12 months from the production date shown on the packaging.
