Are you tired of your current wall colour but unsure how to start painting? Prepping your walls properly is the key to a smooth, lasting paint job. Many people skip crucial steps, thinking they can just apply paint directly. But without the right prep, your new paint job could peel, chip, or look uneven.
This guide will break down each step in preparing interior walls for painting. Whether you're a first-time DIY painter or a seasoned pro, these easy-to-follow steps can help you get that pro finish every time!
Why Wall Preparation Matters
A Smooth, Professional Finish
Proper preparation ensures paint adheres evenly, resulting in a smooth, professional look. Skipping this step could lead to patchy spots, bubbles, or peeling paint.
Longevity of Your Paint Job
Well-prepared walls extend the life of your paint, saving you from frequent touch-ups. Plus, the paint will better withstand humidity and wear and tear.
Step 1: Gather Your Tools and Supplies
Here’s what you’ll need to prepare your walls for painting:
Painter's tape
Drop cloths
Sandpaper (medium and fine grit)
Putty knife
Spackling paste or filler
Mild detergent and water for cleaning
Primer (if needed)
Paint brushes and rollers
Pro Tip: Prep Your Space
Clear the room and cover floors, furniture, and fixtures with drop cloths to prevent paint splatters.
Step 2: Inspect the Walls
Examine the walls closely for cracks, nail holes, flaking paint, or stains. Identifying these issues early allows you to address them, ensuring a smooth final result.
Look for chips and peeling paint: If the old paint is flaking, your new paint won’t adhere well.
Check for mould or mildew: These need to be cleaned thoroughly to prevent any spread under the fresh paint.
Step 3: Clean the Walls
A clean surface allows the paint to adhere properly. Walls often accumulate dust, grime, and oil from cooking or hands, which can ruin your paint job.
Start with dusting – Use a dry cloth to remove dust.
Wash with a mild detergent – Mix a mild detergent with water and use a sponge to clean greasy spots.
Rinse – Go over the wall with a damp cloth to remove any soap residue.
Dry the walls – Ensure the surface is completely dry before proceeding.
Step 4: Repair Holes and Cracks
Filling in cracks and holes is crucial to getting a smooth surface.
Apply filler or spackling paste – Use a putty knife to fill nail holes, cracks, or any other imperfections.
Smooth the filler – Once it’s dry, sand it down for an even finish. This step ensures your walls are seamless before you apply any paint.
Tip: If you’re covering large imperfections, consider using a heavier filler to ensure durability.
Step 5: Sand the Walls
Lightly sanding the walls gives the new paint something to grip onto. It’s especially essential for glossy or previously painted surfaces.
Use medium-grit sandpaper for rougher areas or old, glossy paint.
Switch to fine-grit sandpaper for a smooth finish across the entire wall.
Clean up dust with a damp cloth or a vacuum, as dust left behind can ruin your paint’s finish.
Step 6: Apply Primer (If Needed)
Priming is crucial for certain wall conditions, especially if:
You’re painting over a dark colour
The wall has visible stains or water marks
The wall is a new drywall that hasn’t been painted
Primer creates a uniform surface and helps the paint adhere better. Choose a primer suitable for your wall type and follow the instructions on drying times.
Step 7: Tape and Protect
Using painter's tape along the edges ensures clean lines and prevents paint from getting on unwanted areas.
Apply tape around trims, baseboards, and corners.
Press down the edges firmly to prevent paint seepage.
Use a drop cloth to cover the floor and protect it from accidental splashes.
Step 8: Start Painting
Once the walls are clean, dry, patched, sanded, and primed, you’re finally ready to paint. Use smooth, even strokes and avoid overloading the brush or roller.
Start with corners and edges: Use a brush for precision work.
Fill in the larger areas: Use a roller for a smooth finish across the walls.
Apply multiple coats if needed: Allow each coat to dry completely before applying the next for the best finish.

FAQs
Q1: Do I need to prime walls if they're already painted?A: Not necessarily. If the current paint is in good condition and you’re painting a similar colour, you may skip priming. However, if switching from a dark to light colour or covering stains, priming is recommended.
Q2: How long should I wait after cleaning before I start painting?A: Let walls dry completely, typically about 24 hours after cleaning, to ensure no moisture interferes with the paint adhesion.
Q3: Can I paint over cracked or chipped walls?A: It’s best to patch and sand these areas before painting. Painting over damaged walls will lead to an uneven finish and could cause the paint to peel prematurely.
Q4: What’s the best way to remove painter's tape?A: Wait until the paint is dry to the touch, then slowly peel it off at a 45-degree angle. This will give you clean, sharp lines without pulling up the fresh paint.
Q5: Is sanding necessary if I’m using primer?A: Yes, especially for glossy surfaces. Sanding lightly ensures that the primer and paint stick well, preventing issues like peeling.
