Painting a Room: A Beginner’s Step-by-Step Guide

Painting is one of the cheapest ways to change a room, and one of the easiest DIY jobs to learn. The difference between a professional-looking result and a patchy one is almost always the preparation. The painting itself is the quick part.

1. Prepare the room

Move furniture to the centre of the room or out of it, and cover everything with dust sheets. Remove switch plates and socket covers. Clean the walls with a damp cloth and mild soap, since paint does not stick well to dust or grease.

2. Repair and sand

Fill nail holes and cracks with filler, let them dry, and sand them flush. Lightly sand glossy surfaces so the new paint has something to grip. Wipe away the dust before painting.

3. Tape and prime

Apply masking tape along skirting boards, window frames, and the ceiling line. Press the edge down firmly. Prime new plaster, stains, and big colour changes. A primer helps the paint cover evenly, and it can save a coat.

4. Cut in, then roll

Use a brush to paint a strip about five to eight centimetres wide along the edges and corners. Then, while that strip is still wet, roll the main wall area. Rolling right after cutting in blends the two and avoids visible lines.

• Load the roller evenly and avoid pressing hard.
• Roll in overlapping vertical strokes, working in sections of about one square metre.
• Keep a wet edge by always rolling toward the section you just painted.
• Do not go back over areas that have started to dry.

5. Apply a second coat

Most colours need two coats. Wait for the first coat to dry as long as the label says. Rushing the second coat can lift the first.

6. Remove the tape at the right time

Pull the tape away slowly at an angle while the paint is slightly tacky, not fully hard. If the paint has dried completely, score the edge with a utility knife first so the film does not tear.

Safety and cleaning

Open windows for ventilation. Wash water-based paint from brushes with warm soapy water, and never pour leftover paint down the drain. Take it to a local collection point.

Take your time with the prep, and the painting will look after itself.
