Interior Painting Guide

To paint an interior, make the surface sound, clean and dry, apply the required preparation coats, then work through ceilings, walls and trim. This guide takes you from room planning to cutting in, rolling and drying, with detailed help for each stage.

Plan the rooms and the work

List each room and the surfaces you want painted: ceilings, walls, doors, skirting and window trim. Add photos of damage, stains and peeling. Decide whether rooms will be empty or occupied, and which spaces you need access to during the work.

For a new home, our new house painting guide covers trade coordination and handover. If the work is outside, use our exterior house painting guide for weather, cladding and access.

Choose colour and finish together

Start with fixed materials such as flooring and cabinetry, then compare physical colour samples in daylight and evening light. Our guide to choosing paint colours gives you a repeatable testing method.

Sheen changes how a surface reflects light and how marks show. Compare paint finishes before recording a colour, product and sheen for each surface. Include ventilation and room use when discussing low-VOC paint.

Prepare a clean, sound base

Protect floors and move furniture clear. Check for damp, loose paint and damaged plaster before cleaning with a product suited to the existing finish. Let the wall dry, repair defects, then smooth repairs and remove dust. Before sanding old coatings, establish whether lead paint or other hazardous materials need specialist management.

Our wall preparation guide and primer and undercoat comparison explain how to choose compatible preparation layers.

Set the quantity and application plan

Use our paint quantity calculator for an initial estimate from area, coats and the product's coverage rate. Treat primer and topcoat separately.

The application method depends on access, protection and finish. Compare spray painting and rolling before assuming one method suits the whole house. In wet rooms, bathroom ceiling preparation also needs a moisture and ventilation check.

Allow for drying and aftercare

Touch-dry, ready to recoat and fully cured are different stages. Use the selected product's stated recoat interval, then allow longer where its instructions require it in cooler or more humid conditions. Keep ventilation suitable throughout drying. A dry-feeling surface alone is not the signal to apply another coat.

Our paint drying guide explains the milestones. Keep the product details for cleaning painted walls once the finish has cured.

House painting tips: cutting in and rolling

Work from ceilings to walls, leaving the agreed trim stages until adjacent work is ready. Load a suitable brush lightly and cut a narrow band along the ceiling line, corners and edges. Keep your hand steady and avoid a heavy ridge. Cut in one manageable section, then roll it while the edge remains workable.

Distribute paint evenly with a sleeve suited to the coating and surface. Overlap each pass into the wet edge, keeping pressure light and the spreading rate consistent. Avoid repeatedly working paint that has begun to dry. Check coverage after the coat dries and follow the specified recoat interval.
