How to Properly Prepare a Wall Before Painting — The Essential Steps for a Professional Result

🧑🎓 Introduction:

Even before you get out the roller, proper wall preparation is essential to ensure a smooth, durable, and professional finish. Too often overlooked, this step can make all the difference between a botched job and a flawless wall. Here are our expert tips from Solution à Neuf Inc. to properly prepare your walls before painting.

1. Inspect the condition of the wall

First of all, examine the surface of the wall:

• Are there any holes, cracks, dents?

• Is the wall greasy or dusty?

• Is the current paint peeling?

🔧 Action : Mark all visible defects to be corrected.

🛠️ 2. Fill holes and cracks

Use joint filler or repair plaster to fill:

• Nail or screw holes

• Small cracks

• Damaged corners

🧽 Tip : Use a clean spatula and apply a thin layer to avoid bumps.

🧱 3. Sand the surface

Once the plaster is dry, it is essential to sand the area to:

• Uniform the surface

• Remove old paint or glue residue

• Create better adhesion for the new layer

📌 Use 120-grit sandpaper or a wall sander for large surfaces.

🧼 4. Clean the walls

Even if the wall appears clean, it often contains:

• Sanding dust

• Grease stains (kitchen)

• Fingerprints

💦 Clean with a damp cloth and mild soap. Allow to dry completely.

🎨 5. Apply a primer

A primer is essential if:

• The wall is new (drywall or fresh plaster)

• You go from a dark color to a light one

• You have fixed several defects

🎯 The primer evens out absorption and improves paint adhesion.
