How to Prepare Your Walls Before Plastering

A good plastering job starts long before the plaster is applied. Proper preparation helps ensure that the new surface adheres correctly and produces a smooth, long-lasting finish.

The first step is to remove loose or damaged material from the existing wall. Old wallpaper may also need to be completely removed, particularly when the wall is going to be replastered or skimmed. Plaster should not simply be applied over wallpaper because this can affect adhesion and the finished result.

Any cracks, holes or damaged sections should then be assessed and prepared. Electrical fittings, fixtures and other items may need to be removed or protected before work begins.

The condition of the existing surface will determine whether it requires patch repairs, preparation, skimming or more extensive replastering.
