PLAN THE LAYOUT
Fix the plasterboard horizontally. This will ensure that joints are below eye-level and as a result, any imperfections are more difficult to see. Any glancing light from windows or lights is less likely to show a shadow line if joints are finished slightly raised. Screwing and gluing reduces the number of mechanical fixings in the face of the board, decreasing the number of possible imperfections from problems such as ‘‘popping’’ which are often caused by wet timber.
When fixing horizontally, using taper edge/square edge board makes subsequent installation of skirting and cove/cornice easier.
If end joints are required when fixing horizontally, these should be staggered a minimum of one stud apart, 600mm.
Stud spacing should be at a maximum of 600mm.
For older homes, stud spacing may require that plasterboard sheets be trimmed when fixing vertically.
Never make joints above or below or within 200mm of the corners of windows or doors.
