Insta Stik 750ml handy size

Insta StikTM roofing adhesive for professionals has been developed for the attachment of insulation boards to a variety of substrates on flat roofs. Insta Stik is offered as a portable, disposable pressurised container requiring no external power source. It is a cold applied system that is, quick, easy to use and provides fast adhesion within 20–45 minutes.

Insta Stik Roofing Adhesive 750ml meets the roofers need for a highly portable version for the fixing of rigid insulation boards on smaller commercial and residential roofs.

Under Part L of the building regulations it is now a requirement to upgrade the existing insulation to the current standards when replacing or renewing the waterproofing layer. Insta Stik 750ml Roofing Adhesive will bond up to 14m2 of roof insulation board (based on 19-25 mm beads at 300mm centres).

For a comprehensive NBS J31 specification contact Radmat Building Products.

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
Extruded polystyrene boards
