How Plasterers South Wales prepare cracked interior walls for a smooth plaster finish
Cracked interior walls are a common issue in South Wales homes, often caused by settlement, minor movement or previous poor-quality repairs. Left untreated, these cracks can show through new paint, collect dust and make even a freshly decorated room look tired. Before any new plaster is applied, it is important to understand whether the cracks are hairline surface defects or signs of deeper problems such as blown plaster or loose backing coats.
Plasterers South Wales typically begin by carefully assessing the wall, removing any loose or hollow-sounding plaster and widening fine cracks so repair materials can properly bond. The surface is then cleaned of dust and contaminants, and appropriate fillers, bonding agents or scrim tapes are applied to reinforce weak areas. Where necessary, sections may be re-skimmed or backed with new plasterboard to create a stable base before a full skim coat is laid on to achieve an even surface.
With thorough preparation and a skilled skim coat, previously cracked interior walls can become smoother, more uniform and better suited to modern paints and finishes, helping rooms feel cleaner and more refined without promising structural change.
