Prepare a room for Painting

Walls act as the canvas for your vision of a room.

To ensure paint colours appear as expected and to achieve professional-looking results, it’s important to allow time to adequately prepare your room for painting.


An hour to a day
Depends on room size and the number of flaws it has.


Here’s what you’re going to need:

  • Drop cloths
  • Bucket of soapy water
  • Sponge
  • Bleach
  • Scraper
  • Sand Paper 180 or 240 grade
  • Pre-mixed filler
  • Gap sealant
  • Filling blades
  • Painter’s masking tape


  1. Remove any fixtures, such as picture hooks and light switch covers from walls and remove all furniture and belongings from the room. This creates a safer environment for you to work in and also gives you easier access to those hard to reach corners. Sometimes it may be possible to move furniture into the centre of the room.
  2. Place drop cloths on floors and on any furnishings that remain in the room. Canvas drop cloths are great for absorbing spilt paint while plastic drop cloths act as a waterproof shield, great for protecting carpets.
  3. Before you begin, open any windows in the room to improve ventilation and drying time.
  4. Wash walls with a soapy solution (a small amount of detergent in a bucket of water) to get rid of any dust. Rinse the walls to remove any traces of soap and allow time to dry. This means the paint will adhere to the wall, not the dust.
  5. If any mould is present, use a bleach solution to remove it from walls. Carefully apply the bleach solution to walls using a sponge and leave to soak for 15 minutes. Rinse thoroughly and again, allow them to dry completely.
  6. Assess the walls for any damage or surface lumps and bumps.
  7. If the existing paint is peeling or flaking, scrape back the area to remove the loose paint, and then gently sand the surface so no edges of the old paint are obvious.
  8. Fill any dents or nail holes in the walls with a premixed filler, using filling blades.
  9. Use acrylic gap sealant for cracks or gaps in areas where there may be movement e.g. near doors and windows.
  10. Once the fillers and sealers have set, sand down these areas. While you’re there, sand down any rough or shiny spots to improve adhesion and finish.
  11. Spot prime the filled areas with our Prime Coat
  12. To finish, apply painter’s masking tape to fittings which can’t be removed and any edges which may be fiddly and difficult to paint around, such as skirting boards and fixed shelving.
  13. Once you’re room is prepped, you’re ready to get started. Let’s go paint!
  • For a really effective finish, apply a coat of prime coat to all walls. This allows for good adhesion and blocks out dark or existing colours, making it easier to paint over and providing a smoother, more professional-looking top coat.
  • Remember you’ll need to add a few more materials to the list to complete this step. You’ll need:
    • A 230 or 270mm paint roller frame
    • A matching roller cover with a 9-12mm nap
    • A matching paint tray; and
    • A roller pole
