Painting the walls of your home is a great way of completely changing the style and feel of a neglected or out of vogue room. It’s also a relatively easy and cost effective way too, and as such, it’s a great job to carry out without the need for a professional.

So if you fancy turning that bathroom from mint green to sea blue, or you’ve recently moved and want to add your own stamp to your new home, our helpful and straightforward guide will show you the best way forward.

How to prepare a wall for paint

As with any DIY work around the home, preparation is key. You’ll want to gather the following tools and materials to make sure your paint job goes off without a hitch.

• Paint brushes (large and small)
• Roller set
• White spirit
• Filling knife
• Sandpaper
• Sandpaper block
• Sheets
• Protective clothing

Once you’ve gathered your tools and materials, and you have decided upon your paints, you will want to move onto cleaning the walls for the work ahead.

This is relatively straightforward and simply requires washing the wall down with a detergent before rinsing clean and letting dry. This will help remove any dust and dirt that your wall may have gathered over the years.


How to sand a wall for paint

Once your wall has been cleaned and has been left to dry, you will want to move onto sanding it down. This will make it easier for the primer and paint to adhere themselves to the wall and will help create a smoother and even foundation to help improve your final finish.

Before you start, it’s recommended you wrap your sandpaper around a sandpaper block as this well help cover an even surface area. Run the sandpaper in circle motions over your wall before checking to ensure a smooth surface when completed.


How to prime a wall for paint

If your wall’s previous paint work is still in a good condition and it’s a not too distant shade from your new colour choice, then you most likely will not need to prime the wall beforehand.

However, if you do plan on applying primer you will need to ensure that you buy the correct type of paint. If using emulsion paint, you will need a primer specifically designed for painting, while for an oil-based paint you will require a primer suitable for plaster. It’s also worth choosing a primer that’s of a similar colour to your chosen paint.

Begin by applying your primer evenly over your wall with either a brush or roller. Take your time and work across your wall in sections. Darker colours will often require more coats than lighter colours, but your paint’s instructions will advise on how many coats are required for the best result.

How to paint a textured wall

Painting a textured wall isn’t as easy as it is for a smooth surface, and for obvious reasons. The multitude of bumps and points make it harder to ensure an even covering and the opportunity for sections to be missed is frequent.

1) Preparation

To start, begin as you would any normal paint job, such as removing or covering furniture and placing sheets down on the floor. You will also need the regular tools and materials required for a paint job (as listed above) plus an alkyd primer and an airless sprayer.

2) Test the wall’s texture

Now that you are prepared for the work, you will want to begin by applying the alkyd primer to test the wall’s suitability for the upcoming work. If the wall’s texture starts to soften and crumble after applying the alkyd primer, you will need to use an airless paint sprayer to finish painting. However, if your wall’s texture doesn’t fall away, a standard wall brush or roller will suffice for the work.

3) Painting

What you do now depends on how your wall reacted to the alkyd primer. If your wall held up then using either a standard wall brush or roller is the best option for painting.

• If using a standard wall brush, apply diagonally to best cover the textured area.
• Dip the roller into the tray repeatedly while making sure you get an even distribution of the paint across the roller.

If your wall softened when it had the alkyd primer applied to it, you will need to use an airless sprayer to apply the paint. Make sure to apply horizontally while overlapping each area by roughly 50%.


How to paint over wallpaper

When planning to paint a wall that currently has wallpaper, it’s always best to try and remove the wallpaper first. However, in some cases the wallpaper may have been applied with a strong adhesive and so it is not always possible to easily remove. If that is the case and you have no other options, you should do the following.

1) Preparation

Alongside the regular tools and materials you will require to paint a wall, you will need the following:

• Clean water
• Clean cloth
• Drywall knife
• Wallpaper paste
• Joint compound
• Sandpaper

2) Clean

Once you’ve gathered all the required tools and materials, you will want to start cleaning the wall. First, go over the wallpaper wall with the TSP before rinsing off with the water and then allow to dry.

3) Checking the wall

You will now want to go over your wall to pick out any imperfections that may be visible. Use the wallpaper paste to re-stick any loose sections of wallpaper, while any damaged areas can be fixed with the joint compound.

4) Sand down

After applying the joint compound and letting it dry, you will notice that your wall’s surface will be quite rough from the work. This will need sanding down and should be done with fine sandpaper. A well-sanded wall will help your primer and paint to attach better when applied.

5) A final clean

Any dust or dirt left on the wall when you begin painting will damage the smooth look of your wall when finished so ensure to thoroughly brush down with a clean cloth. Once done, your wall is all ready for you to begin painting.

How to paint neat edges

That annoying part of the paint job that often gets left until last, edges, if not done correctly, can quickly see your good work ruined by wayward paint. To make sure you end up with perfectly painted edges, you will want to do the following:

1) A quality brush

The secret to successfully painting a wall well is simply to use a good quality paintbrush. A good brush will give you better accuracy and a cleaner finish to make that tricky job slightly easier.

2) Tape it off

Using tape is another great method for ensuring neat edges. To start, place tape alongside the inside, right to the edge, of one wall before painting the opposite wall. Don’t worry too much about catching the opposite wall with the paint, as the job of the tape is to prevent marking the wall.

3) Swap sides

Once the painted wall has dried, it’s time to do the opposite. Cover the recently painted wall with tape and paint the opposite side. Remove tape once dried and you are done.

What kind of paint to use

When it comes to which paint to use within your home there is a variety of options available dependent on the condition of your walls.

Base coats

When painting interior walls you will usually want to apply a base coat before painting. This base coat will help give your finished wall that extra protection while giving the coat of paint over a nicer finish.

Finish coats

When it comes to painting over your base coat, you have three choices of decorative finish.


The most common choice for walls, as well as ceilings, matte paint, sometimes known as flat, gives a saturated finish and is great at hiding imperfections such as uneven texture. Though matte paint is quite vulnerable to marking and will require careful cleaning due to its ability to wear down when brushed with a damp cloth.


Offering the finish of matte from a straight on perspective, but with the slight glaze of gloss, eggshell is the perfect choice for those who want the best of both. However, painting with eggshell does tend to show up those small imperfections on you walls especially in direct light.


The ideal choice for a busy, family household, gloss is hardwearing and easy to clean, while it often only requires a single coat over a base coat. It does however reflect light and will show up any imperfections on your wall.


In summary

When it comes to painting your walls there is plenty to consider, but with the right know-how you can turn those tired household walls into bright surfaces that will bring your home to life.
