ATLAS BUILDING BOARD

multi-use extruded polystyrene board

ATLAS BUILDING BOARD

Product description

Resistant to water action – board is made of low absorbable polystyrene with hydrophobic cement-polymer coating.
Forms rigid construction of high resistance to mechanical load.
Forms substrate assuring perfect bonding to cement binders (adhesives, plasters).
Light, easy in transportation – core made of extruded polystyrene ensures low weight, even of large size boards, therefore makes board transportation and fixing easy with no reduction of strength.
Easy and quick in use – any casing shape available, from straight angles to arc-shapes; boards can be cut with knifes, hand saws, jigsaws and electric saws.

Main properties

  • light load-bearing element
  • levels surfaces beneath ceramic tiles
  • element of drywall system
  • on walls and floors, indoors and outdoors

    INSTALLATION

    Go top
    Substrate preparation
    The substrate should be:
    -          clean – free from residues of old mortars, plasters, any loosening pieces, dust and other substances which would impair bonding,
    -          rigid and sound – particularly frames,
    -          primed – any absorbable substrates, e.g. walls made of ceramic brick, cellular concrete, gypsum substrates.
    When using ATLAS BUILDING BOARDS outdoors (e.g. beneath ceramic tiles on terraces) and in zones exposed to intensive water action (shower cubicles), one should coat them with damp proofing (e.g. ATLAS WODER DUO) and protect joints with sealing tapes.

    General principles on use
    Boards should be fixed with cement adhesive mortars. In case of significant substrate irregularities, one should use additional mechanical fixing with anchors. Adjoining boards can be joined with polyurethane or hybrid sealants and adhesives. For the time of assembling and drying, construction should be stabilized with special long thread screws. In order to prevent screw penetration through boards, use screws with special washers extending the contact surface.
    Installation with full surface coating with adhesive mortar:
    1. Clean and prime substrate.
    2. Fill any substrate gaps and irregularities.
    3. Apply adhesive mortar with a notched trowel.
    4. Press boards towards adhesive coat, so whole board surface keeps contact with adhesive.
    5. Check and correct board level (vertical and horizontal).
    6. In order to improve rigidness and sealing, adjoining boards front edges can be joined with polyurethane sealant and adhesive.
    7. Float joints with adhesive mortar, seal with sealing tape then – particularly important for zones exposed to damp.
    Installation with point coating with adhesive and mechanical fixing:
    1. Mark points where adhesive will be applied.
    2. Drill the board through.
    3. Apply adhesive mortar upon marked points.
    4. In order to improve rigidness and sealing, adjoining boards front edges can be joined with polyurethane sealant and adhesive.
    5. Place and press board towards wall, check and correct board level (vertical and horizontal).
    6. When adhesive mortar sets, drill anchoring holes (after 24 h for ATLAS PLUS adhesive).
    7. Install anchors in holes previously drilled in wall (drilled through board and set adhesive). Hammer-in the anchors.
    8. Float joints with adhesive mortar, seal with sealing tape then – particularly important for zones exposed to damp.
    Installation with frame:
    1. Check the frame rigidness and make sure its elements are placed in a way allowing appropriate fixings installation.
    2. Cut board to size.
    3. Screw the board to frame. Make sure it does not displace during assembly. Boards in rows should be staggered.
    4. In order to improve rigidness and sealing, adjoining boards front edges can be joined with polyurethane sealant and adhesive.
    5. Float joints with adhesive mortar, seal with sealing tape then – particularly important for zones exposed to damp.
