Application

Fixing:

Fix boards with decorative side out to receive joint treatment or a skim plaster finish. Lightly butt boards together. Never force boards into position. Install fixings not closer than 13mm from cut edges and 10mm from bound edges. Position cut edges to internal angles whenever possible, removing paper burrs with fine sandpaper. Stagger horizontal and vertical board joints between layers by a minimum of 600mm. Locate boards to a the centre line of framing where this supports board edges or ends.

Plastering:

The face (ivory) of Gyproc WallBoard can be plastered with either Thistle BoardFinish or Thistle MultiFinish. There should be the minimum of delay between completion of the lining and the commencement of plastering.

Jointing:

Gyproc jointing materials produce durable joint reinforcement and a smooth, continuous, crack-resistant surface ready for priming and final decoration. A number of jointing specifications are available to suit the board type, method of application, and site preference.

Decoration:

After the joint treatment has dried, decoration, including any decorator’s preparatory work, should follow with the minimum delay.

Cutting:

This product may be cut using a plasterboard saw. Holes for switch or socket boxes should be cut out before the boards are fixed using a utility saw or sharp knife. When cutting boards, power and hand tools should be used with care and in accordance with the manufacturers’ recommendations. Power tools should only be used by people who have been instructed and trained to use them safely. Appropriate personal protective equipment should be used.
