How Much Preparation Does a Room Need Before Plastering?

Before plastering begins, the room needs to be assessed carefully. The amount of preparation required depends on the existing condition of the walls and ceiling.

Old wallpaper often needs to be removed before plastering. Loose material, damaged plaster and areas that are not firmly attached to the surface may also need attention.

Fixtures such as shelves, wall fittings and other obstacles can make preparation more complicated. Radiators may need to be removed if the homeowner wants the wall behind them properly plastered.

The preparation stage can also involve filling holes, dealing with damaged areas and protecting floors and surrounding surfaces.

Every room is different, which is why it is useful to assess the property before deciding exactly what work is required.
