Decorative Lime based plaster capable to replicate various surface structures (weathered sandstone surface; timber relief; wood bark relief; travertine relief; etc.) Big variety of application methods in cope with endless variations of color pairing of base coat  and finishing wax makes it possible to use ATACAMA for decoration of surface nearly of any kind (decorative panels, inserts and entire walls) either in classical or modern styles. Contrast of structure can be developed either by application of tinted CERA wax or by polishing of upper parts “of relief” which as a result will became darker and will obtain higher gloss. Combination of a.m. methods (i.e. staining by CERA wax with subsequent polishing by metal trowel) is also possible.

Prior to plastering surface has to be coated by KVARC primer. ATAСAMA has to be applied by rectangular or trapezoidal trowel with rounded edges and corners. While ATAСAMA is still wet – work the surface in order to create desired patterned structure (see options (1, 2, 3, 4) below). Recreation of relief: 1) Weathered sandstone surface. Work the surface by rectangular or trapezoidal trowel in „criss-cross” or wavy mode. 2) Travertine relief. Work the surface by foamed roller and then smooth obtained grainy pattern by metal or plastic spatula in one or different directions depending on desired structure. 3) Timber relief. Work the surface by parallel passages of specially engraved “wood graining” rubber applicator . Most realistic wood structure is replicating while rocking the applicator from one edge to another during continuous (non-stopping) parallel passages. 4) Wood bark structure. Work the surface with parallel movements of special trowel with plastic bristles leaving striped  tracks. Created pattern  has to be smoothened using the spatula by movements directed along the relief structure. Application can be conducted at air and surface temperature above +10°C and relative humidity below 85%. Drying time of  ATACAMA at +20°С – 12-18 h  depending on relief thickness . Spreading rate: 1,5-3,5 m²/l depending on relief. (Pattern developing. Weathered sandstone surface structure developing has been used below just as an example. All the other reliefs can be treated using the same technique.) Fully dried surface of Atacama has to be sealed by colorless Cera wax using brush, woolen glove or roller (fig.4.1) in order to equalize absorbing rate all over the surface as well as to prevent blending of lime stains. (In case of one color structure recreating (with no subsequent staining of surface by tinted Cera ax) sealing of ATACAMA surface by colorless CERA wax is not necessary.) – Application of tinted CERA. Apply tinted CERA wax evenly on to 1-2 m² surface area unit by circular movements of woollen glove (fig.1). While CERA is still wet work the surface by woollen glove again in order to ensure uniform wax spreading all over the surface. (Structures oriented in one direction (like „timber” or „wood bark”) have to be stained by CERA wax using the brush (fig.2). Wax excess has to be removed from upper parts of pattern by spatula moving it along the relief and holding its blade at acute angle . If deeper contract accentuating is desired it is advisable to sand the upper parts of pattern using sand paper (grain size index of about 180 is recommended).  In case glossy aspect and deeper color contrast of patterned relief is required it is advisable to burnish completely dried surface by inox trowel holding it at acute angle (as parallel as possible) to the surface.  Burnishing is mandatory only in case of ATACAMA application without subsequent staining by tinted CERA wax ! It is recommended to apply wax VENETO CERA in order to accentuate contrast of the surface, increase the gloss and to make the surface water repellent. Wax has to be applied by thin layer using woollen glove. After wax is dried surface has to be polished by soft cloth or woollen glove by circular movements. In case high level of washability is required it is possible to protect the surface by varnish instead of VENETO CERA (Ekoakva, Luoten or Paneļu laka of required gloss degree) are recommended. In case pearlescent sparkling effect is desired it is also possible (optional) to admix pearlescent powder PERLIUM of required colour directly to the varnish prior to it’s application.
