What's the story

Creating vibrant murals requires a lot of preparation, especially when it comes to the walls. African muralists have mastered the art of preparing surfaces to ensure their works are both beautiful and long-lasting. By following these preparation techniques, you can ensure that your mural's colors pop and last for years. Here are five essential wall preparation secrets that every aspiring muralist should know.

Surface selection

Choose the right surface

Choosing the right surface is important for any mural project. Different surfaces have different textures and absorbency levels, which can affect how paint adheres and looks when dry. Smooth concrete or plaster walls are usually ideal as they provide a good base for detailed work. Avoid surfaces with peeling paint or loose materials, as these can compromise the integrity of your mural over time.

Surface cleaning

Clean thoroughly before painting

Cleaning is the first step to preparing a wall for a mural. Dust, dirt, grease, or old paint can interfere with how well the new paint sticks to the surface. Use a pressure washer or scrub the wall with soapy water and a stiff brush to remove any debris. Let it dry completely before moving on to the next step.

Primer application

Apply primer for better adhesion

Applying primer is key to ensuring that the paint adheres well and the colors remain vibrant. A high-quality primer seals porous surfaces and provides an even base for the paint. Choose a primer compatible with your chosen paint type, whether acrylic or latex-based, and apply it evenly across the entire surface using rollers or brushes.

Paint testing

Test paint compatibility on small area

Before committing to your full mural design, test paint compatibility on a small area of the wall. This helps ensure that your chosen colors look as expected when applied to the surface and that they adhere properly without any adverse reactions. Allow this test patch to dry completely before assessing its effectiveness.

Moisture control

Address moisture issues promptly

Moisture behind walls can ruin any mural, no matter how well-prepared the surface is. It's important to check for any signs of dampness or leaks before starting your project. If you find any, fix them immediately. Use waterproof sealants if necessary, to prevent moisture from seeping through the walls in the future. This way, your mural will be protected from water damage and last longer.
