Insta Stik
is applied in beads to the underlying substrate prior to placing the insulation boards. Walking of the boards is required thereafter until the adhesive has “cured” (20- 45 minutes) to ensure good adhesion and level joints.

Coverage of Insta Stik is approximately 100m2 per tank based on a 19-25mm wide bead placed at 300mm centres. Insta Stik bead sizes and centres are determined by several factors including substrate type, board type height of roof and pressures exerted by wind force.

Glass tissue faced boards
Bituminous felt faced boards
Stonewool insulation
