Application Instructions

All curtains are supplied with sufficient adhesive for the 50 mm overlap. The adhesive can be applied to
one face and pressed together, although it is best to apply a small layer to each face and apply
together, giving a much quicker hold. Just hold together for approximately 1 minute, to allow the
adhesive to grip. 1 litre of Adhesive is sufficient for 50 metres of curtain.
Should the Curtain be installed in a windy area, Envirograf ST50 or ST75 Class 0 Adhesive Tape can
be applied over the glued joint to hold it more securely while the Adhesive dries.
For fixing the top, bottom and ends of the Curtain: For timber supports use Envirograf FB/T Battens,
fixed through to the timber with 30 mm large head clout nails. For concrete, block or brick fixing, use
FB/C Metal Straps – 25 mm wide, with 2 mm holes every 300 mm apart. These can be fixed with spit
nails, screws, pop rivets (steel) or self tapping screws to the steel work.
Where cutting around services is required;
1. Wrap around the service with a section of the curtain and adhere together using the adhesive.
2. Cut a cross – X – in the barrier to allow the service through. Once the service is wrapped,
adhere the cut area of the curtain to the wrapped service.
3. If necessary, fit a patch over the curtain with the adhesive, using a section of curtain as the
patch.
