What it is
Plaster is usually cement and sand mixed with water. Gypsum plaster is a faster, smoother option for inside walls. Outside plaster must keep out rain, so it is thicker and denser.
Types and key points
- Cement-sand plaster: inside and outside
- Gypsum plaster: smooth, inside only
- Ready-mix plaster: consistent, less waste
- Typically 12 to 20 mm thick
Why it matters
Good plaster keeps walls dry and gives paint a sound base; cracks and hollows show up later as patches and damp.
