FOR INTERNAL AND EXTERNAL USE

USE

ATLAS CERPLAST is a priming mass used for substrate preparation under thin-layer renders: mineral (e.g. ATLAS CERMIT SN, SN-MAL, DR, PS), resin (e.g. ATLAS CERMIT N and R, ATLAS DEKO M) and gypsum renders. ATLAS CERPLAST is a general-purpose priming agent for all types of substrates. It can be used on mineral surfaces (e.g. cement render, cement-lime render), on plasterboard panels and on smooth substrates of very low absorptivity (e.g. concrete walls and ceilings, OSBs). ATLAS CERPLAST is also an inseparable part of ATLAS, ATLAS STOPTER, ATLAS STOPTER K-10, ATLAS HOTER and ATLAS ROKER thermal insulation systems. For 6 months, ATLAS CERPLAST can be used as a temporary protective layer of thermal insulation system (before the finishing layer of the thin-layer render is applied). It is suitable for indoor and outdoor use.

PROPERTIES

ATLAS CERPLAST is a ready-to-use priming mass based on quartz flours and acrylic resins. It is a white priming agent. Additionally, it is available in three colours (clinker, brown and graphite) as a prime coat for selected colours of ATLAS DEKO M mosaic renders. It is efficient, very convenient and easy to use. Aggregate content enhances surface coarseness, making application of successive layers easier, and increases the contact area of the render or adhesives with the substrate. Application of ATLAS CERPLAST improves adhesion and prevents appearance of stains on the thin-layer render resulting from inappropriate substrate preparation or its properties.

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. Before work commencement, prime the substrate using ATLAS UNI-GRUNT. Fill in irregularities and defects using e.g. ATLAS LEVELLING MORTAR, ATLAS PLASTERING MIX or ATLAS STOPTER K-20, ATLAS HOTER U and ATLAS ROKER W-20 adhesives (in jointless thermal insulation systems).

PRODUCT PREPARATION

ATLAS CERPLAST priming mass is ready to use. It may not be combined with other materials, diluted or thickened. Having opened a bucket, mix its contents until homogenous.

APPLICATION

Distribute ATLAS CERPLAST on prepared substrate (evenly on the whole surface) with a roller or paintbrush. Do not apply the mass below +5°C. Begin surface plastering or facing fixing after the mass completely dries i.e. after ca. 4÷6 hours from its application. 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

On average, 0.3 kg is sufficient for 1 m2.

TOOLS

Roller or paintbrush Wash the tools with clean water directly after use.
