Project Overview

The easiest way to give your bathroom a makeover is by giving it a fresh coat of paint. This step-by-step guide will show you how to paint your walls and ceilings without making a mess. Before you start, choose an oil-based, semi-gloss finish that is mould and mildew resistant. It’s also important to keep your bathroom well ventilated.

Quick Tip: How to paint with a roller

When you’re painting a ceiling with a roller, keep the end of the roller facing the side of the surface that you have already cut in. This will make sure that the roller’s metal frame doesn’t damage your walls.

Step by Step Instructions

1 Cover your fittings
2 Prepare your painting surface
3 Apply painters tape to floor and wall edges
4 Start by cutting in the edge
5 Apply undercoat to the ceiling
6 Apply undercoat to the walls
7 Apply the topcoats
8 Apply the paint colour
  • Step 1. Cover your fittings

    Before you start, cover all of your fittings in the bathroom in plastic to prevent paint splatters getting on them and don’t forget to put a drop sheet down. 

  • Step 2. Prepare your painting surface

    If you’ve got any mould, get rid of it with a bleach solution before you begin. You’ll need to sand the paint coats off your plaster walls and ceiling before you paint. Use a sanding pad and 150 grit sanding paper for a nice even finish. Then wipe down the surfaces with a cloth to get the dust off. 

  • Step 3. Apply painters tape to floor and wall edges

    Put some painters tape down along the edges of any floor or wall tiles to stop any paint getting on them and to keep your paint lines straight when you’re cutting in. 
  • Step 4. Start by cutting in the edge

    When painting a surface, always start by cutting in the edges. Use a cutting brush, which is cut on an angle, to make sure you get an even, clean job. Then apply your undercoat to all the edges.

  • Step 5. Apply undercoat to the ceiling

    After cutting in your ceiling and walls, paint the ceiling with the undercoat. Use a roller for good coverage when painting larger surfaces. Make sure you keep the flat surface of the roller on the wall side when rolling, so the metal bracket doesn’t damage your wall.

  • Step 6. Apply undercoat to the walls

    Once you’ve done the ceiling, start painting your walls with the undercoat. Follow the same process from Step 5 and leave to dry before applying your topcoat.
  • Step 7. Apply the topcoats

    Once the undercoat is dry, apply your topcoat the same way you applied the undercoat in Steps 4-6. Start by cutting in your ceiling and walls again along your marking tape for the topcoat. Then paint the ceiling using your roller, applying an even paint spread. Let the topcoat dry and give the ceiling another topcoat. 

  • Step 8. Apply the paint colour

    If the wall colour is different to your ceiling, you’ll need to thoroughly clean all of your painting gear so that you don’t mix your paint colours. Tape the ceiling up along the wall join to protect your new paint, and then cut in your wall edges (See Step 4). Now roll your first topcoat onto the walls and let it dry. Add a second coat, especially if it’s a dark colour. When the second coat is dry, remove all the tape from your walls.
