• The wall surface is made ready byensuring it level, dry and clean.

• The fabric spanning details as perdrawings are marked on the wall.

• SB10 is installed on the wall surfaceon the marked lines with metalfasteners at 300mm centresembedded in plastic sleeves. Theholes are made with an impact drill.Any level differences in wallsurfaces are made plumb by insertingpacking shims behind the SB10.*

• The Base Tape protective cover isunpeeled on the base of the Stretchtracks.

• Stretch tracks are then installed onthe SB10 with Stitch staples at25mm centres with a staplingmachine. In the case of non-masonry walls where SB10 is notinstalled the Stretch tracks arestapled directly to drywall

• The Strand panels installed on thewall surface with M8x25mm metalfasteners that are angularly driventhrough the panel to the wall. In thecase of non-masonry walls theStrand panels are stapled afterapplying light spots of Stick S7adhesive.

• Synth PF is then friction fitted withlight spots of Stick S7 adhesive.

• Cara fabric is then aligned to the Stretch tracks by following thefabric threadline or pattern. The Cara fabric is stuck on the AlignTape (by removing the protective film) at the same as being stretchedand tucked into the Stretch tracks with the tucking tools.

Note: Each Stretch track featuresa unique dual tape mechanism- Base Tape on the base of thetrack for a true and continuoussecure grip of the track on thewall surface, and Align Tape onthe top of the track for a true andcontinuous secure grip of thefabric on the track.
