Internal plastering gives an interior wall or ceilings a covering of plaster made from cement sand or gypsum. The surface provides an ideal base for further decoration by paint or paper. The plaster finish is smooth or textured, depending on the interior design decisions. The team at Pro Plastering Southampton can help with all internal plasterwork from skimming to full traditional wet plastering.

Plaster applied to walls and ceilings of a room transforms it into a space that is clean and comfortable for modern living. Also, the plaster finish protects your walls from damage, and it is versatile in letting you choose how to decorate and redecorate your rooms as your needs and tastes in interior design change.
Architectural mouldings like ceiling roses and cornices are created from internal plaster and can be incorporated as part of an interior design brief when plastering a room. There are many different types of plaster, but the essential ingredients are gypsum, lime, or cement mixed with sand.
The binder defines the type of plaster.
Gypsum: Sometimes called plaster of Paris,’ Gypsum plaster produces a fine-grained finish and has excellent fire-resistant properties.
Lime: A mixture of lime (calcium hydroxide) with a filler (typically sand) that can include animal hair or other fibres (increases strength and reduces cracking and shrinkage). This traditional plaster gives a more flexible and breathable layer than gypsum or cement. Lime plaster is the preferred material for older, historic houses.
Cement: You can achieve a smooth layer with cement plaster, but it is generally a base coat finished with gypsum plaster. This combination gives the moisture resistance of the cement plaster combined with the smooth finish of the gypsum.
Clay: If you are looking for a sustainable alternative to modern plasters, you can opt for a clay plaster with added fibres for strength. It provides a breathable plaster in a range of natural colours and does not need painting.
You can refer to plaster by its application – for example, board finish plaster is a product used on top of plasterboard and bonding plaster forms an undercoat when plastering new walls. Different formulations have different properties like heat, moisture, or impact resistance
Traditional plastering on masonry involves building up to three layers of wet plaster on the wall if starting with a rough bare wall. The plaster compound mixed with water goes on with a trowel. Base layers need scoring while damp to produce a rough surface for the additional layers. The final layer offers a choice of a textured or smooth finish.
Plastering combined with drylining or plasterboard on a masonry or stud wall involves a final skimmed layer giving the appearance of a traditionally plastered finish. Plasterboard has replaced lath and plaster for all except heritage applications.
Traditional plastering is labour intensive and takes longer to apply than modern techniques like dry lining. The advantages include:
Durability – the chemical reactions as the plaster cures produce an impact-resistant wall coating able to withstand the knocks of everyday living.
Less dusty to install than drywall – the only dust in the process comes during the mixing of the plaster before use. Drywall installations need sanding down as part of the finishing process.
Appearance – you can add architectural mouldings into the plastered surfaces to provide some stunning rooms from all historical periods. Additionally, a skilled plasterer can offer many different textures.
Better noise absorption – a fully plastered wall has better because of the increased density of the wall covering gives acoustic properties than a plasterboard wall.
Increased fire resistance – a traditional lime plaster has inherent fire resistance, and fires spread more slowly than in a room with standard plasterboard.
Versatility – it is straightforward to use appropriate qualities of plaster in different parts of the room – heat resistant plaster around a chimney breast.
Straightforward installation – there is less mess with traditional plastering because the plaster is mixed and applied directly to the wall. Plasterboard can be damaged in transit or suffer from being exposed to water on site.
Even if you only need a skim coat on top of the plasterboard it is worth using a skilled professional plasterer. Wet plastering requires craft, experience, and artistic flair. Our team at Pro Plastering Southampton can match the right plasterer and materials to your project. We can manage your entire interior design plastering from restoring a period building with ornate plasterwork to giving you a stunning textured finish to a contemporary room.
