DECORATIVE MOSAIC RENDER OF INCREASED RESISTANCE TO WASHING, CLEANING AND ABRASION

FOR INTERNAL AND EXTERNAL USE

USE

ATLAS DEKO M is designed for manual preparation of internal and external decorative plaster coatings. It can be used on all even mineral substrates such as concrete, traditional cement plasters, cement plasters, plasterboard and wood-based panels and reinforced layers of thermal insulation systems of buildings. It is particularly recommended for pedestals, foundations, balcony walls, etc. A wide range of available colours (the colour palette includes 60 compositions) allow for a large degree of freedom in the design and finish of exhibition rooms, car dealerships, offices, staircases, as well as residential and public areas.

PROPERTIES

ATLAS DEKO M is a ready-to-use render based on acrylic resin with the addition of coloured quartz aggregate. It is efficient, convenient and easy to use. It provides hydrophobic layer permeable for water vapour characterised by low stress concentration. High content of pure polymer ensures its exceptional resistance to various kinds of damage, weather conditions, washing, abrasion, etc. Note: ATLAS DEKO M is milky-white when applied. It obtains its full proper colour when dried. High air humidity and low temperature may extend the setting time and change colour shades. In case of constant contact with water, the render may go milky white; the effect disappears when the surface dries. Therefore, avoid render application when it is exposed to long-term effect of water or humidity (e.g. on horizontal surfaces or those with small inclination, small ponds, etc.) and elements (foundations, fences or retaining walls) without appropriate damp insulation.

SUBSTRATE PREPARATION

The substrate should be stable, even and structurally sound i.e. strong enough; it should be free from anything that may weaken adhesion, in particular dust, dirt, lime, oil, fat, wax. Remove existing paint and render coats of insufficient adhesion. Afterwards, prime the substrate using ATLAS UNI-GRUNT. Fill in irregularities and defects using e.g. ATLAS LEVELLING MORTAR, ATLAS PLASTERING MIX or ATLAS REKORD finishing mortar. Before plastering, regardless of substrate type, provide a prime coat made of ATLAS CERPLAST priming mass. Additionally, it is possible to use ATLAS CERPLAST colour priming mass in the following colours: clinker, brown or graphite.

PRODUCT PREPARATION

ATLAS DEKO M is ready to use. Having opened the bucket, mix its contents with a slow-speed mixer until homogenous.

APPLICATION

Apply ATLAS DEKO M over prepared and primed substrate as a layer using a float made of stainless steel. Thickness of the layer should correspond with the aggregate grain size. Always smooth wet render in the same direction. The lack of uniform render texture due to local irregular floating may result in differences in colour shades on the plastered surface. Experimentally (for a given type of substrate and given weather) determine the maximum area that can be prepared in one technological cycle (application and floating). Apply the mix using the “wet on wet” method, preventing one batch from drying before application of another one. Otherwise the “seams” will be visible. Plan technological gaps in advance e.g. in corners or building angles, under rainwater pipes, etc. Protect the plastered surface during work and when it dries from direct sunlight, wind and precipitation. Drying time depends on the substrate, temperature and relative humidity of air and is from ca. 12 to 48 hours. In case of increased humidity and temperature ca. +5°C, render setting time may extend. Substrate and ambient temperature during work and when render dries should be +5°C, max. +25°C. Note: to avoid differences in colour shades in case of colour mosaic renders, apply render of the same production date on the same surface. The information comprises basic instructions of product application and do not relieve users of responsibility for work in accordance with good construction practice and OHS regulations.

CONSUMPTION

Depending on layer thickness and substrate type, on average: ca. 3÷4 kg is sufficient for 1 m2 ca. 4.5÷ 5.5 kg is sufficient for 1 m2 (render no.: 120, 122, 216, 218, 219, 222, 313, 314, 317, 420, 514, 515). It is recommended to assess precise amount based on a test.

TOOLS

Drill with mixer or smooth float made of steel. Wash the tools with clean water directly after use.

PACKAGING

Plastic buckets: 15 kg, 25 kg Pallet: 540 kg in 15 kg buckets, 400 kg in 25 kg buckets.

STORAGE & TRANSPORT
