Technonicol adhesive mastic #27
The mastic is designed for adhesion of extruded polystyrene foam plates to bitumen and polymer-bitumen insulation materials, as well as to concrete, metal, and wooden surfaces in foundation insulation systems.
Description of material
TECHNONICOL adhesive mastic #27 is produced from oil bitumen, special fillers and organic solvent. The mastic is paste-like, which allows for it to be reliably secured to the heat-insulating slabs on vertical surfaces. The material is ready to be used completely, and it is easy to be used.
Method of application
The mastic is applied as points or strips by using a putty knife or comb putty knife. The mastic should be applied to all corners and in the centre of a fixed slab. When applying strips, their width should not be less than 40 mm, and at least four strips should be applied per square meter. When fastening the mastic in points it is distributed using stains with a surface coverage of 50-80 g for each stain. The stains are distributed in regular intervals on 10 pieces per 1 m2. Mastic surface coverage — 0.5–1.0 kg/m².
Store in dry place protected against sunlight at a temperature between –20°C and +30°C. Guaranteed storage period — 12 months.
