Transforming Spaces: A Guide to Painting Interior Walls

Transforming Spaces: A Guide to Painting Interior Walls
11 January, 2024

Your home is a canvas waiting to be transformed, and one of the most effective ways to breathe new life into your living spaces is by painting the interior walls. Whether you're a seasoned DIY enthusiast or a first-time painter, this guide will walk you through the process, from choosing the right colours to applying the final coat of paint. Let's embark on this creative journey and turn your walls into a masterpiece.

Step 1: Planning and Preparation

Before you pick up a paintbrush, it's crucial to plan and prepare for the painting project. Start by assessing the condition of the walls. If there are any cracks, holes, or imperfections, these will need to be repaired and then sand the surface smooth. Remove any loose or peeling paint, and clean the walls thoroughly to ensure proper adhesion.

Next, gather your painting supplies. You'll need:

High-quality paint in the desired colours, AIM recommends Crown Trade Emulsion.
Paint rollers and brushes
Painter's tape
Drop cloths or plastic sheeting to protect floors and furniture
Primer (if necessary)
Stir sticks and paint trays
Rags for cleaning up spills

Step 2: Choosing the Right Paint

Selecting the right paint is a crucial decision that will impact the overall look and durability of your walls. Consider the following factors:

Finish: Paint comes in various finishes, each serving a different purpose. Flat or matte finishes hide imperfections but are less durable. AIM offers Crown Trade Scrubbable Matt which is durable and washable, suitable for high-traffic areas.

Colour: The colour palette sets the tone for your entire space. Choose colours that complement your furniture and decor, and consider the mood you want to evoke in each room. Lighter colours can make a room feel more spacious, while darker shades add coziness.

Quality: Investing in high-quality paint may cost more upfront, but it will provide better coverage and durability, ultimately saving you time and money in the long run.

Primer: In some cases, applying a primer is necessary to ensure proper adhesion and a smoother finish. If you're painting over a dark color or a surface that hasn't been painted before, using a primer is recommended.

Step 3: Prepping the Room

Now that you have your supplies and chosen the perfect paint, it's time to prep the room. Start by removing furniture or covering it with plastic sheets. Use painter's tape to protect trim, skirting boards, and any areas you don't want to paint. Lay down drop cloths to protect the floor, and if possible, ventilate the room by opening windows and doors.

Step 4: Applying the Primer

If you're using a primer, apply it evenly to the walls and allow it to dry completely before moving on to the next step. Primer enhances paint adhesion and helps achieve a more uniform finish.

Step 5: Painting Techniques

Now comes the exciting part – applying the paint. Here are some painting techniques to ensure a professional-looking result:

Cutting In: Use a high-quality brush to "cut in" or paint along the edges, corners, and trim where a roller may not reach. This provides a clean and precise finish.

Rolling: Use a paint roller for the main wall surfaces. Roll the paint in a "W" or "M" shape to evenly distribute the paint. Work in small sections, blending each section into the next to avoid visible lines or streaks.

Two Coats: For optimal coverage, apply at least two coats of paint. Allow each coat to dry completely before applying the next. This ensures a more durable and long-lasting finish.

Step 6: Finishing Touches

Once the final coat is dry, carefully remove the painter's tape to reveal crisp, clean lines. Touch up any imperfections with a small brush, and admire the transformation. Allow the paint to cure fully before moving furniture back into the room.


Painting interior walls is a rewarding DIY project that can instantly refresh and elevate the look of your home.
