What You’ll Need

Before you begin painting your interior walls, make sure you have the right tools ready to go.

Having quality tools on hand makes the job faster, easier, and far more precise, especially when aiming for an even paint finish.

Painting Basics: What Painting an Interior Wall Involves

Painting a wall is more than simply applying a coat of paint.

A successful result starts with proper preparation, choosing the right paint for the surface, and using high-quality brushes and rollers to achieve smooth, even coverage. Understanding how to repaint interior walls correctly helps you avoid common mistakes like patchy paint, roller marks, and uneven edges.

When painting preparation is done right, the painting itself becomes much easier!

Before You Start: Wall Painting Checklist

Protect the Area

Lay down a drop sheet to protect your floors and furniture from spills, splatters, and dust. Move or cover nearby furniture before you begin.

Clean the Wall

Wash the wall with sugar soap to remove dust, grease, and grime.

Inspect Your Wall

Before starting, check the wall carefully for cracks, holes, dents, or peeling paint. Preparing the surface properly is one of the most important parts of achieving a professional-looking finish.

Seal Small Gaps and Fill Cracks and Dents

Seal any small gaps around trims or joins, use Monarch Mini Gap Filler to create a neat, professional base. Additionally, Monarch Mini Fill Sand Go can be used to fill any cracks, dents, or holes.

Lightly Sand the Surface

Once filler has dry, lightly sand the wall to remove rough patches and create a smooth painting surface. Make sure to wipe the wall clean to remove any dust before painting.

Tape Up Edges

Tape around skirting boards, trims, light switches, and power outlets to help create crisp, clean lines.

Painting Process: Step by Step

Step 1: Ventilate the Room

Good airflow helps paint dry properly and improves the final finish, especially when painting smaller interior spaces.

Step 2: Cut In Around the Edges

Start painting by cutting in around the edges of the wall. Hold your brush at a 45-degree angle to give yourself better control and cleaner lines.

Step 3: Roll the Main Surface

Use your roller to paint the rest of the wall in smooth, even strokes.

Step 4: Allow the Wall to Dry

Leave the wall to dry completely. Between coats, wrap brushes and rollers in foil to stop them drying out.

Step 5: Apply the Second Coat

Repeat the same process for the second coat to build colour depth and achieve an even, professional finish.

Step 6: Remove Tape and Touch Up

Carefully remove the masking tape, then fix any missed spots or uneven areas using leftover paint.

Cleaning Your Tools

Looking after your painting tools means they’ll be ready for the next project, and they’ll perform better for longer.

• Wash brushes and rollers thoroughly to remove excess paint.
• Clean trays, buckets, and extension poles after use.
• Store everything in a clean, dry place.
