Installation guide AMF TACET®
The work for the jointless base and top renders is carried out above head and in a backwards direction. For this a level platform scaffold is required, which safely enables this work.
2. Installation of the CD grid structure.
The CD grid structure, both primary and main profiles are fixed to the soffit using rigid hangers. If movement joints, access panels or other installations are required, these need to be considered during the installation. The connection of the ceiling at perimeters features a shadow gap.
Areas larger than 100 m² should be divided by movement joints. The grid structure must be adapted accordingly.
3. Fixing and gluing the tiles with staggered tile joints
The first tile is installed. Tile should be screw fixed to the CD profile maintaining a 10mm clearance from all walls.
Before installation of the other tiles continues, adhesive is applied to the two joints and the tiles butted together. The tiles are screw fixed to the CD profile. The rest of the ceiling continues in the same manner.
4. Bonding the end profiles
When all the AMF TACET® tiles are installed, the end profiles are glued to the edges with POWER-ELAST.
5. AMF TACET Basic Base Plaster
AMF TACET® Basic Base Plaster is supplied premixed in containers. The plaster is mixed with water using a suitable tool.
The plaster is applied with a notched trowel in wide channels. The applied base Plaster is scraped in a crosswise direction. The second scrape is carried out in a perpendicular direction to the first.
The surface is smoothed twice, once with a narrow and once with a wide finishing trowel. The thickness of the Base Plaster should be 2 mm. The finished plaster should be left to dry for 48 hours.
The surface is checked for evenness using a side light. All unevenness and ripples are sanded using a sanding block.
6. AMF TACET Top Coat Acoustic Plaster
AMF TACET® Top Coat top render is supplied in premixed containers and stirred with the addition of water. If the ceiling is to be a different colour to standard white, the coloured acoustic plaster should be prepared as per the installation and handling guidelines.
The Top Coat plaster is applied with a notched trowel and started in a corner of the room.
The applied Top Coat is scraped twice in a crosswise direction.
The surface is smoothed with a finishing trowel always using the same amount of pressure. The thickness of the Top Coat should be 2 mm.
After the surface has dried slightly the entire surface is smoothed again with a longer finishing trowel. Using light pressure, all bumps and unevenness is evened out. The drying time of the finished render is 48 hours. Only then can installations, such as lights or smoke detectors, be installed in the ceiling.
