    ATLAS CERAMIK system is an external thermal insulation composite system (ETICS). The thermal insulation consists in the application of EPS or XPS boards onto the outer side of the wall, next the installation of a base coat with reinforcing fiberglass mesh, and further application of the finishing layer made of ceramic tiles fixed to base coat with the use of an adhesive and finished with a grout. Due to the type of the finishing layer, the  insulation boards must be mechanically fixed through the first layer of mesh.

    Work conditions
    Carry out the work in dry weather, at the substrate and ambient temperature not lower than +5°C and not higher than +30°C. The only exception is the ATLAS STOPTER K-20 adhesive, which can also be used at 0°C, assuming that after 8 hours from the work completion the temperature does not drop below -5°C. The facade should be on time of thermal insulation work protected and secured against precipitation, strong wind and direct sunlight - it is recommended to use fine mesh scaffolding covers. Insulation works should be carried out in dry conditions (no precipitation, relative humidity below 80%).

    General provisions
    Before the work commencement, evaluate the substrate technical condition and on that basis decide on the scope and the method of surface preparation. For the time of works remove any elements hindering tight adhesion of the thermal insulation panels and the finishing coat application. An additional layer of insulation will increase the thickness of the walls, and therefore it will cause the need to increase the reach of flashings, downspouts anchors, etc. For the time of works the windows and doors should be protected against the dirt by a plastic film.
    Requirements for the substrate
    The substrate should be aged, sound, stable, even, clean and dry. The absorbent substrates should be primed with ATLAS UNI-GRUNT, smooth and non-absorbent (concrete) with ATLAS CERPLAST. The substrate should be even to the extent enabling easy execution of a plane formed by the bonded insulation boards on the walls. Clean the surface from any layers which may weaken mortar adhesion, dirt, loose and dusty elements.
    Note! Particular attention should be paid to the proper assessment and preparation of substrate with problematic bearing capacity, e.g. finished with glass-mosaics, glazed brick, covered with paint coats, etc. If in doubt, conduct a pull - off test of adhesion (the ultimate tensile strength should be above 0.08 MPa) or apply 8÷10 cubes of EPS 10x10 cm each, in various places of the facade and tear them off after 3 days. The use of thermal insulation system for buildings with reinforced concrete sandwich walls, should always be preceded by a thorough assessment of their technical condition. This applies to the technical condition of the metal fittings (hooks, pins, rods) as well as to how they are connected and interact with the elements of the wall.
    Skirting boards installation
    The insulation should be commenced with the installation of the starter tracks. They support the first row of thermal insulation boards, facilitate to maintain the uniform level of successive layers, strengthen the bottom edge of the system, and the bottom edge drip prevents water bleeding. The boards should be installed horizontally on the plinth of the building, not lower than 30 cm above the ground level, which provides protection from the effects of rising damp and protects against dirt - mud particles brought by raindrops reflected from the ground. Instead of skirting boards, it is permitted to use strips of armour mesh or two layers of fiberglass mesh.

    Polystyrene boards application
    In the case of even substrates, the mortar can be applied with the use of a notched trowel (with notch size 12 mm) – the adhesive is applied then directly onto the board and not onto the substrate. In the case of less smooth surfaces the adhesive should be spread on the board surface using the “strip - point” method. It consists in the application of continuous circumferential bead (at least 3 cm wide) at the edge of the board and 6÷8 patches of 8÷12 cm in diameter evenly distributed on the whole surface. Peripheral bead is placed at a distance from the edge, so that when pressed to the wall the mortar is not squeezed out of the contour and side edges. The adhesive mortar applied on board should cover at least 40% of its surface (after pressing down to the substrate at least 60%). Thermal insulation application should commence from the building corners. The first\ row of the boards is fixed on the starter tracks,, the subsequent rows positioned so that the vertical board joints are staggered and overlapped at the building corners. It is unacceptable to fit the edges of the insulation boards with the edges of the reveals on the façade. As the adhesive is applied, the board should be placed onto the substrate, moved tightly to the already fixed boards and pressed – be sure to control the plane with a level. If the adhesive is squeezed out the board contour, it should be removed. If there are gaps between adjoining boards, we recommend filling them with cut stripes of polystyrene or low expansion polyurethane foam.
    Insulation boards sanding
    The surface of insulating boards applied to the substrate should be even, so when the mortar sets (after ca. 24 h), the boards should be sanded with the use of sanding boards or floats covered with coarse sanding paper. It eliminates any board edges slips. In the case of polystyrene boards installed 3 months earlier or more sanding and removal of any surface tarnish is mandatory.
    Additional elements installation
    In order to increase the system resistance against mechanical damage, to allow free drainage and execution of expansion joints - the finishing profiles should be installed on the fixed thermal insulation layer. These profiles are installed at every specific locations of the façade (i.e. corners, reveals, sills, etc.). They can also be simultaneously installed during the base coat mesh embedding. For profiles embedding, use adhesive mortars ATLAS STOPTER K-20 or ATLAS HOTER U.
    Reveals corners strengthening
    In all corners of window and door reveals, additional reinforcing mesh strips (rectangles with dimensions of 20 x 30 cm) embedded in the adhesive mortar ATLAS STOPTER K-20 or ATLAS HOTER U should be installed. The strips should be applied diagonally, at a 45° angle in relation to the line set by the edges of the reveals.
    Base coat (reinforced layer) application
    Because the finishing coat of ATLAS CERAMIK consists of ceramic tile cladding, it is required to apply the base coat (reinforced layer) and to install mechanical fixings in the same work phase. For application of the reinforced layer two layers of mesh embedded in ATLAS STOPTER K-20 or ATLAS HOTER U adhesives are used. Mechanical fixings are installed through the first mesh layer. The base coat can be installed after min. 3 days from the boards application. Apply the adhesive mortar onto the surface of the installed insulation boards and spread it using a notched trowel (notch size 10 - 12 mm). The adhesive should be spread in vertical strips of width slightly greater than the fiberglass mesh width. Then, starting from the top, subsequent strips of mesh are applied and in a few points along the entire length embedded in the prepared adhesive layer. The adjoining strips of mesh should overlap horizontally and vertically by a minimum coverage of 10 cm (15 cm in quoins). Mesh overlaps should not coincide with the joints between the insulation boards. When applied, the mesh should be carefully embed in the adhesive. In order to embed the mesh evenly, the adhesive is squeezed with the slightly inclined trowel led from the top, in the direction from the center to the mesh strip side. The correctly embedded mesh should be completely not visible under adhesive coat and should not be in direct contact with the polystyrene boards surface. The next step is the installation of mechanical fixings through the first layer of mesh. The fixings should be with galvanized steel pin, in an amount of min. 8 pcs per 1 m². Detailed information about the number of fixings, their distribution, length and depth of anchorage should be specified in the thermal insulation technical design. When fixings are properly installed, their plates should be lightly pressed into the adhesive layer. Then the entire surface should be covered with the next fiberglass mesh embedded thoroughly in the mortar and smoothed with a float.

    Contact layer application
    After ca. 3 days from reinforced layer application, the contact layer made of ATLAS CERPLAST priming mass might be made, however it is not obligatory.
    Ceramic cladding application
    The deformable cement - based adhesives of C2TE S1 type according to the PN-EN 12004:2008 standard are recommended, i.e. ATLAS PLUS, ATLAS PLUS WHITE or ATLAS PLUS EXPRESS. When applying the tiles, one should pay special attention to ensure proper adhesion of an adhesive in order to eliminate the possible cavities under the cladding, e.g. notched trowel marks. Taking these factors into account, it is recommended to use the ‘double spreading’ method, consisting in the distribution of an adhesive both onto the substrate - with a notched trowel, and on the bottom side of the tile - with the smooth side of a trowel. Only then after the tile is pressed to the substrate and slightly moved. Follow the adhesive coat thickness advised in the technical data sheets. Do not cover too large area with an adhesive at the same time, as the spread adhesive retains its binding properties for 10 - 30 minutes (depending on the substrate and ambient characteristics). The position of a tile can be adjusted delicately within 10 minutes after it is pressed. Remove the excess of the adhesive appearing in the joints after pressing the tile immediately.
    The grouting of the ceramic cladding should be commenced after the complete setting of adhesive, i.e. after ca 24 h from the
    tiles application. It is recommended to use ATLAS ARTIS GROUT. Due to cladding operation conditions the width of the joints should be within the range from 6 mm to 20 mm (the width should be adequate to the size of the tiles used) and the percentage of the joints on the entire surface should not be less than 6%. In order to avoid various colour shades, it is recommended to use grout of the same manufacturing date and the same batch number (shown on the packaging). Conduct the grouting of the same plane with no breaks and on adjoining scaffolding levels, using the compound of the same manufacturing date and batch number. Keep equal water/dry mix proportions. The cladding should be protected against precipitation (mesh covers on scaffoldings) within min. 3 days from its application; it refers to the temperature of +20 °C and relative humidity of 60%; in less positive conditions the slower setting of the used materials should be considered.
    Expansion joints of the ceramic cladding
    The construction and plane expansion joints of the insulation as well as the angle ones should be repeated on the surface of

    the ceramic cladding. The surface should be divided into smaller sections of max. 9 m². In case of installation of the ATLAS CERAMIK thermal insulation system on large and high facades it is recommended to apply additional horizontal consoles or stabilizing brackets.
