Installation Hints & Tips

Vex box Tip 1

Fill the box with newspaper or use the off-cuts or, a combination of both to stop the box filling with plaster.

Vex box Tip 2

Where there are large gaps around the insert, these should be filled with board adhesive, Carlite Bonding or similar, prior to skimming.

Vex box Tip 3

When using the twin profile, ensure that of the two preformed ‘cutouts’ that accommodate the fixing lugs in the box, the centralised cutout goes over the larger sliding lug.

Vex box Tip 4

If there is no edge to mark off the depth gauge, use the Vex Box as a straight edge to span the gap.
