Glue is only required on the shiplap joint, glue outer edge of bottom shiplap prior to laying next board using Gorilla Grip 1 hour expanding polyurethane or Sika SuperGrip® 30 Minute expanding polyurethane.

Maglok™ Dragonboard® (MgSo4) does NOT require stainless fixings. Use corrosion protected cement board type fixings (grade3 galv).

Sheets should be kept under a cover if there are long periods between delivery and installation. Dry sheets are easier to lay and weigh less.

Sheets are to be laid perpendicular to the joist with the ship lap edge spanning across the joist. Sheets should be fitted to a staggered (brick pattern) layout.

Yes, they can!

H&S regulation call for all material to be cut with a vacuum saw. Use a Fibre Cement cutting wheel on a skill saw or plunge saw. Before use, please see our Respiratory and Eye Protection statement on our Installation page.

Weight of the sheet is approx 21 kg m2.

If solid timber joist are particularly wet or damp, it is suggested that the sheets are glued to the joists and any nogs using a 10mm bead of Gorilla 940FC to assist in reducing possible movement that could result in a creak caused by tension built up as the timber dries.
