It wasn’t that long ago that wallpaper was the only thing any self-respecting wall would be seen wearing this season. Whilst it’s still in style in some circles, painting a wall has become the go-to fashion accessory for rooms around the world.

Painting a wall sounds like the easiest thing in the world. Buy paint. Buy roller. Paint a wall, but it’s not that simple, at least it’s not if you want it to look great. Preparing your wall before you add a lick of paint is crucial to it looking as good as it can be. If you’re paying a professional painter and decorator, then having the walls well prepared in advance of their arrival will also save you money, so how do you do it?


Preparing Your Walls for Painting 

Almost all walls, even brand new ones, will need at least some degree of preparation before they even see a paintbrush. 


Remove Adhesive

If the walls have had wallpaper on previously, then the first thing you’ll need to do is to remove any excess adhesive from the walls. This can also happen if you’ve had anything hanging via adhesive strips or decorative wall stickers.

If you leave adhesive on, then it will be clearly visible when you paint over it. Adhesive will come off quite easily with some soapy water and a little elbow grease. Don’t over-saturate the wall, try and find a spray bottle to use if possible. If this doesn’t work, then a plastic putty knife will work just as well. Remember not to cut into the wall or you’ll be making more work for yourself.



Once the walls are clear of any bumps, then the next thing to do is to protect any outlets or switches. If you’ve got power sockets or light switches on the wall, then you can either cover them with painters or masking tape which will stop paint splashes getting on them. 

Alternatively, and only if you can do it safely, you can remove the covers from the walls so you can paint behind them. You don’t have to fully disconnect them, but undo the screws and pull the switches away from the wall.


Filling Dents & Holes

There are few places to hide when it comes to painting walls, so it’s essential you ensure the painting surface is as good as it possibly can be. This means that if there are any dents, holes or rough areas, they need to be resolved. Also, any previous paint may have bobbled over time making the surface uneven. This is where things like fillers and sandpapers will be a bonus. Any holes or dents will need to be filled. You can get various types of fillers, depending on how deep the hole is. Even if it’s just a very fine hairline ‘crack’, it will still need to be covered.

Once filled, wait for the filler to dry and then sand it down until it’s level with the surface of the wall. Most small areas can be done manually with a sanding block and some sandpaper. If the wall needs more work, then an electric sander might be a better option. It’s important to wait a little while after sanding, but before you start painting. Sanding will create dust and it will settle. You don’t want it to settle on the walls, so grab a damp cloth or sponge (or even a vacuum cleaner with a brush attachment) and wipe the wall clean of any lingering dust.

Skirting Boards

The final piece of prep work you’ll need to do is to protect things like skirting boards, window sills, mouldings (e.g. coving) and architraves around doors. Covering the edges with masking tape will stop the paint from seeping onto them and ensure some nice clean lines.

With all of these processes complete, your wall should now be ready for a fresh coat of paint. Whether you’re tackling it yourself or getting a professional to do it for you. The paint going onto the wall will look a whole lot better thanks to these simple steps that anyone can do.
