A common problem faced by the period house owner is inappropriate coverings or treatments of ceilings. For example, ceilings can be covered with Artex or other textured plasters, or textured and woodchip papers. If you remove these coatings, be prepared to have to replace the whole ceiling as the removal process may weaken the ceiling or reveal major flaws. Beware that some Artex contains asbestos.

Loose or Cracked Plaster快快快[]

In most old houses, ceiling plaster has lost some or all of its 'key' to the laths and the careless DIY-er can

cause complete failure.

It is the part between the laths which is the weakest link; once broken, these 'ears' no longer hold the plaster up and if enough areas break, then the ceiling will fall.

Breakage can occur for several reasons:

  • Water damage from a burst radiator or pipe
  • Vibration and shock from war-time bombs, children’s activity and modern traffic
  • Stress on the joists from heavy furniture or new stud walling causing the joists to drop and push against the ceiling

Hairline cracks should not be of concern but larger cracks or any with a 'step' indicating failure should be monitored or repair seriously contemplated..

Missing Plaster[]

Where flawed plaster has been mishandled, it can fall off the ceiling. Small areas of missing plaster mouldings can be reconstructed. Areas of flat plaster are best patched although it is difficult to achieve a perfect surface. Larger areas are best replaced completely.

Stains and Mould[]

Stains commonly arise from cigarette and pipe smoking. Sugar soap will remove this before redecoration. Staining also occurs if a chimneybreast has become damp; the moisture washes oils from the soot to the surface.

Mould occurs because of damp. You need to determine the type of mould and the cause.

If plaster becomes stained due to damp or mould, any painor paper applied over it tends to stain subsequently.

Paint Obscuring Moulding[]

Every time plaster embellishments such as cornices and centre roses are repainted, the detail in the

plasterwork becomes more and more obscured. It is an easy but satisfying process to remove the paint. Follow the advice on the

restoration page to strip this paint.
