What Is Interior Painting? A Guide for Australian Homeowners

What interior painting covers

Interior painting covers every painted surface inside a home. That means walls, ceilings, trims, and doors. It also covers specialty finishes like feature walls. So a full repaint does all of these, not just the walls.

Painting the inside of your home usually follows three stages: choose colours, prepare the surfaces, then apply the coats. To plan the look, see our guide to choosing paint colours. To get the surfaces ready, see how to prepare walls for painting.

Surface preparation — the most important step

Quality interior results depend on preparation. This includes washing surfaces to remove grease and dust, filling holes and cracks, sanding back flaking paint, and applying primer to bare or repaired areas. Skipping prep leads to paint failure and poor adhesion over time. Our wall preparation guide walks through each step in order.

Choosing the right paint finish for each room

Different rooms need different durability. Flat or low-sheen finishes suit bedrooms and living areas. There, washability matters less. Semi-gloss works better for trims and wet areas. Think bathrooms, laundries, and kitchens. These face moisture and regular cleaning, so they need a harder coating.

How many coats are needed?

Most interior repaints use two topcoats over any primer. Sometimes you need one extra primer coat. That applies on bare plasterboard, after big repairs, or when a light colour goes over a very dark one.

What affects the cost of interior painting?

Room count and ceiling height drive most of the size. Other factors matter too. These include the surface condition, the number of colours, and whether trims and ceilings are in scope. A room with heavy cracking or water damage costs more than a simple repaint of sound walls.

Professional vs DIY interior painting

DIY interior painting works for handy owners on simple jobs. Professional painters add prep know-how, the right product choice, and the right tools. So they get an even result across large areas and tricky surfaces. For a whole-home repaint or major repairs, a pro often works out cheaper. That counts the time and wasted materials.
