DIY: How to Paint Interior Walls Like a Pro with Dulux Paint for Any Surface

II. What You Need to Get Started

A. Interior paint: Choosing the right Dulux colour and finish

Think about what the room is used for, how much natural light it gets, and the existing decor when you pick a Dulux colour.

Pick a finish based on the look you want and how the wall will be used:

• Matte/Flat: Non-reflective and soft, good for low-traffic areas, and it hides small imperfections well.
• Eggshell/Low Sheen: A slight sheen, easier to wipe down, and suited to moderate-traffic areas.
• Satin/Silk: A smooth, pearl-like sheen, hard-wearing, and good for high-traffic areas plus doors and trim.
• Semi-Gloss/Gloss: Shiny and very washable, which makes it a solid choice for kitchens, bathrooms, and feature walls.

B. Tools and supplies you may take time to gather

Get your gear together before you start:

• Dulux interior paint in your chosen colour and finish.
• Brushes (angled and straight) for cutting in and detail work.
• Paint rollers and covers (medium nap for smooth surfaces, thicker nap for textured walls) to cover large areas quickly.
• An extension pole for reaching high areas.
• A paint tray and liner for loading the roller and keeping the mess down.
• Drop cloths or plastic sheeting to protect floors and furniture.
• Painter's tape for masking off edges and trim so you get clean lines.
• Sandpaper for smoothing rough or glossy surfaces before you paint.
• Spackling compound and a putty knife for filling holes and cracks.
• Cleaning supplies like sugar soap, sponges, and cloths to prep the walls.
• Primer for prepping the surface, if you need it, so the paint sticks and lasts.
• A stepladder or scaffold for reaching ceiling edges and high walls safely.

III. Preparing the Room and Walls

A. Clearing and masking the area

– Move as much furniture out of the room as you can, and cover what is left with drop cloths so you have room to work.

– Remove or cover light fixtures, switch plates, and outlet covers to keep paint off them.

– Lay drop cloths or plastic sheeting on the floor and tape down the edges.

– Run painter's tape along baseboards, window frames, and door frames for a clean edge.

B. Cleaning and repairing wall surfaces

– Wipe the walls with a damp cloth or sponge to clear dust, cobwebs, and light grease.

– Wash grimier walls with sugar soap and water, then rinse and let them dry fully.

– Fill any cracks, holes, or dents with spackling compound, let it dry, then sand it smooth and level.

– Sand glossy surfaces so the new paint has something to grip.

C. Priming and undercoating interior walls (if necessary)

Apply Dulux Precision Sealer Undercoat or Dulux 1 Step Water Based to:

• Bare, untreated plasterboard or plaster, to give the paint a stable base.
• Walls with stains or residue that could bleed through.
• Surfaces where you are making a big colour change, so the new colour reads true.

Let the primer dry fully, following the instructions on the tin, before you paint over it.

IV. Step-by-Step Instructions for Painting Inside Walls

A. Cutting in edges and corners

1. Load a trim brush with Dulux paint and tap off the excess.

2. Start at a top corner of the wall and paint a 2 to 3 inch strip along the ceiling edge.

3. Work the paint in smooth, even strokes and feather the edges so they blend into the main wall.

4. Keep cutting in along baseboards, window frames, door frames, and corners.

5. Let the cut-in areas dry a little before you start rolling.

B. Using a paint roller on the main wall surface

1. Pour your Dulux paint into a tray, filling it about halfway.

2. Dip the roller in the paint, then roll it on the tray's ridges to take off the excess so you get an even load.

3. Start rolling the paint onto the wall in a "W" pattern for consistent coverage.

4. Overlap each section slightly and keep a wet edge so you do not get visible seams.

5. Keep rolling until the whole wall is covered, reloading the roller as you go.

6. Let the first coat dry fully (usually 2 to 4 hours) before you decide whether you need a second coat.

C. Applying multiple coats

– Most jobs need two coats for full coverage and an even colour.

– If the first coat looks patchy or the colour is not where you want it, put on a second coat.

– Use the same cutting in and rolling steps for the extra coat.

– Let each coat dry fully before you start the next one.

D. Touch-ups and cleanup

– Pull the painter's tape off while the final coat is still slightly wet for a crisp line.

– Check the walls for missed spots, drips, or marks, and touch them up.

– Take up the drop cloths and plastic sheeting carefully, folding them inward to hold any dry paint flakes.

– Wash your brushes, rollers, and trays in warm soapy water (for water-based paints) or mineral spirits (for oil-based paints).

– Store leftover Dulux paint somewhere cool and dry for future touch-ups.

V. Tips and Tricks for a Professional Finish

A. Techniques for various wall surfaces and textures

– For textured walls, use a thicker nap roller cover so the paint gets into the crevices evenly.

– For glossy surfaces like tile, use a bonding primer first so the paint grips properly.

– For trims and details, use a good angled brush and a steady hand to get clean, sharp lines.

B. Common mistakes to avoid

– Do not skimp on prep. It is the single biggest factor in how the finished wall looks and how long it lasts.

– Do not load too much paint at once, or you will get drips and uneven coverage. Build it up in thinner, even layers.

– Do not rush the drying time between coats. Paint that goes on too soon can peel or streak.

– Do not paint in direct sunlight or a draught, since both affect how the paint dries and sticks.

C. Helpful hacks to save time and effort

– Use an extension pole on your roller to reach high areas without a ladder. It is easier on your back and neck too.

– Wrap brushes or rollers in plastic during breaks so they do not dry out.

– Use a paint edger tool for a clean line between the wall and the ceiling or trim.

– Keep a small container of your wall colour on hand for quick touch-ups.

VI. Maintaining Your Freshly Painted Interior Walls

A. Proper drying and curing time

– Give the paint at least 24 hours to dry before you hang decor or move furniture back in.

– Paint can take up to 30 days to cure fully, so go easy on the walls during that time.

B. Cleaning and touch-up tips

– Dust the walls now and then with a soft dry cloth or a duster on an extension pole.

– Clean dirt or marks with a damp cloth and a mild detergent, and do not scrub too hard.

– Touch up chips or scratches with your reserved paint and a small brush.

C. When to consider repainting

– Repaint when you see fading, chipping, or wear that touch-ups will not fix.

– Change the wall colour when your taste or the room's use shifts.

– High-traffic areas like hallways, kitchens, and bathrooms usually need a refresh every 3 to 5 years.

VII. Conclusion
