Step By Step Guide On How To Paint A Room


Step 1: Choose a Paint Color and Finish

The options are endless when selecting the right paint colour for the room, especially when you have to counsel with your partner first before choosing. You’ll also have to decide on how much paint you’ll need and the right colour. From warm to bold or a cool shade, it’s also important to take into consideration the different types of finish.

Gloss finish ­- Glossy paint reflects the light in any room. It looks great in rooms with wooden furnishings, and it’s easily washable.

Semi-gloss finish – If you’re looking for durable paint that will reflect enough light and look great in rooms that get cleaned frequently, like the kitchen and bathroom – a semi-gloss finish is what you need.

Matte finish – A matte finish works well on uneven walls with small imperfections because it doesn’t reflect the light, making the imperfections unnoticeable.

Satin finish – A satin finish is smooth with only a bit of shine and is best used in high-traffic areas like kids’ play areas, hallways, living rooms and bedrooms.

Step 2: Cover floors and furnishings

One of the worst things about painting a room is that it’s a messy job. Painting a new room can easily destroy your favourite furnishings if the proper coverings are not in place before opening the paint tin.

One of the best ways to protect your floors, window frames, and furnishings from paint droplets and splatters is to use fabric drop cloths to cover everything. Using plastic drop cloths is not advisable as they can be slippery and easily moved when stood on.

Step 3: Prep the Trim and Walls

When painting a wall, it’s necessary to clean them with wall cleaner to remove any dirt, cobwebs, and grease before doing any patching or painting.

To understand if your wall has any bumps or indents, shine a torch on them for a visual inspection and fill in any small holes or cracks with a patching compound. Remove any nails or peeling paint, then finally sand all the patches with sandpaper for a smooth finish.

Cover any plug sockets or switch plates with masking tape or remove them, and prime the walls and ceilings.

Step 4: Tint the Primer

Professional painters always prime the walls and ceilings first. A primer is used as the first layer coverage to prevent paint bleeds and improve adhesion, reducing the chance of paint peeling and blisters forming.

Step 5: Start Off By Painting the Ceiling

A good painter will paint the ceiling first and the walls last so that any paint drips or paint splatters from the ceiling can be rolled over.

  • Pour the paint into the paint tray, just enough so that you can carry it standing on the step ladder and use an angled paint brush to paint the edges of your ceiling.
  • Dampen the roller before using it with water or paint thinner and dip it into the paint tray, removing the excess paint so that it doesn’t drip everywhere.
  • Paint the whole ceiling from one end to the other using the extension pole, rolling in the same direction.
  • Once the ceiling is completely painted, have a look to see if it needs a second coat, and if it does, roll in the opposite direction to the first coat.

Step 6: Paint the Trim Before the Walls

Just like the ceiling, you should paint the wall parameters (known as the trim) using an angled brush.

Once you have painted the trim, let it dry, then use painter’s tape on the trim and continue to paint all of the walls. If you are having the trim the same colour as the walls, you can skip the taping step.

Step 7: Apply Tape Along the Edges of the Trim

Before you start painting the walls, you should apply painter’s tape around the edges of the trim so that you don’t get any paint on it. Plus, it will avoid contrasting brush and roller marks, leaving you with a perfect line between the ceiling and wall.

Step 8: Cut In the Edges of the Wall with a Paintbrush

Use your paintbrush to cut in around the edges of the taped wood trim (around 2-inch thickness) before using the paint roller on the walls. 

Cutting in blends better with the wall paint, leaving you with a professional finish at the end.

Step 9: Roll Paint the Walls

Pour the paint into the tray and gently roll the roller backwards and forth in the well so that the roller is well covered in paint. Avoid using too much paint at this stage. Work your way from the base of the wall to the ceiling, rolling as many times as possible without reloading the roller to ensure it’s completely coated in paint.

Step 10: Remove Tape and Tidy up

Once the wall is fully painted, score along the tape edge using the putty knife and peel the tape from the trim. Clean the brush and roller with hot soapy water, remove all of the cloth, and open the windows to let the fresh paint smell out.


Should I wash the walls before painting?

Yes, washing the walls is necessary prior to painting so that the paint adheres to it and it will look better when finished.

Can I paint over old paint?

If the old paint is similar to the new one (latex paint, for example), you can proceed to paint straight over it.

What happens if you don’t prime your walls first before painting?

If you don’t apply a prime coating first, you run the risk of it peeling off, and your wall will not look as professional without it.

Do you paint from top to bottom or side to side?

It’s best to paint from the ceiling down after you’ve cut in the edges to avoid any mistakes.
