How to Paint a Room

One of the best ways to enhance the interior of a house is to paint it. Painting can turn a dark drab space into an airy positive space, and make the room feel clean and fresh again. To get the best results and to save time, professional painting services are recommended to paint a room, however it can be undertaken by individuals with sufficient time and skill to do so.

If you do decide to take the risk and paint it yourself, there are some important steps to follow to get the best results. This article will go over these important steps and highlight what you need to think about and need in how to paint a room.

Choice of Paint and Colour

Before you even start, you need to decide on a variety of aspects. What type of paint do you need? Do you want a textured or flat finish? Gloss or semi? What colour? All these factors will depend on the type of room and your finished décor, so take the time to seriously think about what it is you want to achieve.

You should also consider how you will apply the paint, whether you use spray (quicker, but messier and uses more paint) or traditional roller and brush.


Before you do anything, move any furniture you can out of the room. Next cover what remains with large sheets. Ensure your flooring is well protected with sheets or plastic drapes.

Next, remove face plates from electrical sockets and switches, but be careful not to expose yourself to the wiring. If necessary, tape over the sockets so as to prevent shock.

Preparation is the key part to having a good finish to your room. This means that all the walls and ceilings must be perfectly flat, free of debris and dirt, and have any holes filled in and sanded. In fact, it's often this stage that takes the majority of time, so do not be afraid to take the extra effort to get it right. Poorly prepared walls and ceilings will not be hidden by the paint.

Most holes and dents can be filled with a simple filler that is applied as a paste and then sanded off when dry. This is quite easy to do and provides good results. Use a 120 grit paper to give your walls and ceilings a nice smooth texture. You can also use caulk to fill gaps and holes between the trim and wall too.

Once you have sanded and completed this part of the job, ensure that the walls are free of dust and that they are clean before you start painting. To do this, you can use a vacuum and then use warm water with dish soap and a sponge to clean the surface. Repeat with clean water and then wipe down until dry.

Before you start painting, there is one other thing you must do, and that is to place painting tape to mask off areas you don't want painting. This special tape is perfect for painting because when removed, it doesn't leave a sticky residue or pull the paint off with it as some masking tapes do.

Having done this, you should be ready for the next step in how to paint a room.

Cutting In

Before you begin painting, pour some paint from your can into a small plastic container, and do your painting from this. It firstly makes it easier to carry, and secondly means that if there is debris still left on your wall, it isn't going to contaminate your primary paint supply, ie from the tin.

For the next step in this how to paint a room process, we can actually begin to paint. Cutting in arguably is the most skilful part of the job, as a steady hand is often required. Thankfully, you should have already applied painting tape to mask areas you don't wish to be painted, and this will make the job easier.

With cutting in, you are going to paint a strip around the perimeter of your walls and ceiling. Use a 2" - 3" brush and paint a band around. Don't forget the corners. The brush will basically apply paint to the areas the roller cannot go. Paint very carefully, and it's best to begin on the corner areas first to allow yourself to warm up and understand how the paint flows from your brush before you tackle more intricate areas.

Using the Roller

With the cutting in complete, it's time to use the roller. Pour some paint into your rolling tray, and dampen your roller nap with water (for latex paints) or thinner (for oil based paint).

Dip your roller into the paint, and then slowly roll it back to the grated part of the tray. Ensure that the entire nap is covered with a thin layer of paint.

Next, apply the paint to the walls. This is done with 'w' or 'm' like strokes over the walls, and then overlapped with vertical strokes to fill in the gaps. Use this technique for the entire surface until you have completely covered the area.

If a second coat is required, wait until the paint is touch dry before applying this second coat.


Once the walls and ceilings are complete, it's time to remove the painting tape, and prepare to do the trims. Before painting these, reapply any painting tape to avoid the trim paint from getting on your wall paint.

Then use a half inch angled brush to paint your trims carefully and the job should be complete.


As you can see, the process of how to paint a room can potentially be messy, complex and time consuming. For a quality job free of errors and mess, the best thing to do is to hire a professional.
