When budgeting for interior decorating, calculating cost per square meter for wall painting is one of the most reliable starting points. Interior walls are typically the largest painted surface in a room, and their condition plays a major role in overall cost.
Interior wall pricing depends on preparation level, the number of coats required, and the finish type selected. Smooth, sound walls that only need light sanding and filling are relatively efficient to paint. Damaged or heavily stained walls require additional preparation time and sometimes specialist primers.
The layout of the room also influences labour time. Large uninterrupted walls are quicker to coat than walls filled with alcoves, shelving, pipework, or tight corners. Even when the measured area is identical, the time required can vary significantly.
Another important factor is colour choice. Strong colour changes, especially moving from dark to light shades, can require additional coats. Certain pigments naturally require more paint to achieve full coverage.
When reviewing quotes, ensure that the specification states the number of coats included, whether primer is included where necessary, and whether materials are supplied. Without this clarity, two square meter figures are not directly comparable.
