Plasterboard
Showing results 1-12 of 12
Ceilings – flaking paint (particularly on fibrous plaster ceilings)
-
Deterioration due to age; joint stopping not dry when painted; oil-based paint applied over acrylic
-
Damp ceiling
Plasterboard ceiling sagging
-
Insufficient number of plasterboard sheet fixings; fixings inadequate to hold plasterboard sheets; ceiling lining has had weight applied such as a person standing on the lining instead of joists in the roof space
-
Ceiling joist spans are too great for the timber size; joists have been overloaded
-
Joists have rotted due to leaks or high roof space moisture levels
-
Water from roof leak wetting insulation and being absorbed by ceiling lining
Ceilings – plasterboard coved cornices cracked
-
Building movement; earthquake shaking
-
Not properly stopped when installed
Plasterboard cracking at tight stopped wall ceiling junction
-
Framing shrinkage
-
Building movement; earthquake shaking
Wall linings generally – mould/mildew growth
-
Condensation forming regularly because the wall is not insulated, the house is not sufficiently heated and/or internal moisture levels are too high
Wall framing location is visible
-
Condensation forming on the areas between the framing because the wall is not insulated – mould growth is the result of regular condensation
-
Mould is forming on the framing locations because a thermal bridge (framing has lower thermal performance than the insulated part of the wall)
Plasterboard linings – cracking
-
Building movement; timber framing shrinkage
-
Joints not taped before apply stopping compound (joint taping was rarely done before 1975)
-
Land settlement
-
Wind or earthquake shaking
Plasterboard – dent or puncture
-
Impact damage
Plasterboard disintegration
-
Plasterboard has become wet from a wall, window or roof leak
Plasterboard flush-stopped joints have a noticeable ridge
-
Slight over-filling of the joint which becomes obvious in glancing light conditions (light parallel to the surface such as from a wall washer light fitting)
Plasterboard – nail popping
-
Timber shrinkage
-
Plasterboard is not fixed tightly to the framing
-
Fixing was through a daub of adhesive which has shrunk and pulled the lining in
-
Building movement
Plasterboard cracking at internal corners
-
Building movement; framing shrinkage
-
Earthquake shaking
