Transforming your living space with a fresh coat of paint is one of the most impactful and budget-friendly home improvement projects you can undertake. Whether you're refreshing a tired room or completely changing its character with a new colour scheme, knowing the right techniques can make the difference between amateur results and a professional-looking finish that lasts for years.

Preparing Your Walls for a Flawless Finish

The secret to achieving professional results lies largely in thorough preparation. Many DIY enthusiasts make the mistake of rushing straight to the exciting part of applying colour, but professional painters know that preparation is what truly determines the quality of the final result. Kamerolli, a respected name in painting supplies, recommends allocating nearly half of your project time to proper wall preparation.

Cleaning and repairing wall surfaces

Begin your painting project by thoroughly cleaning your walls with a soft, damp sponge and sugar soap to remove any dirt, grease, or residue that might prevent proper paint adhesion. This step is especially important in kitchens where cooking residue can accumulate on surfaces. Next, carefully inspect the walls for any damage such as cracks, holes, or loose wallpaper that needs addressing before painting can begin.

For filling holes and cracks, use an appropriate filler such as those from the Polycell Polyfilla range. These products are designed for various gap sizes, with options like Polycell Advanced Polyfilla being suitable for deeper holes up to 50mm in a single application. After applying filler, allow adequate drying time as specified on the product instructions, then sand the filled areas until they are smooth and flush with the surrounding wall surface. A sanding block attached to a pole can save considerable time and effort during this process.

Protecting Your Space with Drop Cloths and Tape

Protecting your floors, furniture and fixtures is a crucial step that should never be overlooked. Lay down drop cloths to cover the entire floor area where you'll be working, ensuring they extend well beyond the walls to catch any potential drips or splatters. Canvas drop cloths tend to stay in place better than plastic sheeting and absorb any spills rather than creating slippery surfaces.

Apply decorator's tape along the edges of skirting boards, window frames, door frames, and any other areas you want to protect from paint. Press the tape down firmly to create a tight seal and prevent paint from bleeding underneath. This step is essential for achieving those crisp, clean lines that distinguish professional paint jobs from amateur attempts. Remember to remove the tape while the paint is still slightly damp to avoid peeling off any dried paint with it.

Selecting the Right Materials for Your Project

The quality of your materials significantly impacts both the appearance and longevity of your paint job. While it might be tempting to save money on cheaper products, investing in quality paint and tools often proves more economical in the long run, providing better coverage, requiring fewer coats, and delivering a more durable finish.

Choosing quality paint and understanding finishes

When selecting paint, consider both the type and finish that best suits your space. For interior walls, water-based latex paints are generally preferred as they dry quickly, have minimal odour, and clean up easily. If you're painting over oil-based paint, you'll need to apply a special primer first to ensure proper adhesion.

Understanding paint finishes is essential for selecting the right product for each room. Matt emulsion is excellent for hiding wall imperfections and provides a sophisticated, non-reflective appearance, making it ideal for living rooms and bedrooms. Satin and silk finishes offer a mid-sheen level that balances durability with a subtle glow, suitable for higher-traffic areas. Eggshell provides a gentle sheen that's more resistant to cleaning than matt but less shiny than silk. For areas exposed to moisture or requiring frequent cleaning, like kitchens and bathrooms, semi-gloss or gloss finishes offer superior durability and moisture resistance.

Essential tools: brushes, rollers and accessories

The right tools make a significant difference in achieving a smooth, even application. For brushes, consider synthetic bristles for water-based paints as they last up to five times longer than natural bristles and maintain their shape better. Use a 2-inch or 3-inch brush for cutting in around edges and corners of walls, and a 1-inch or 2-inch brush for more detailed work around doors and skirting boards.

When it comes to rollers, match the pile length to your paint and wall texture. Short-pile mohair rollers work well with silk emulsion on smooth surfaces, while medium-pile sheepskin rollers are better suited for matt emulsion and slightly textured walls. Lambswool roller covers offer excellent coverage for most wall surfaces and help achieve a smooth finish. Remember to invest in quality roller frames that feel comfortable in your hand and allow for smooth rolling action.

Additional accessories that prove invaluable include paint trays with disposable liners for easy cleanup, extension poles to reach high areas without constantly climbing a ladder, and a good quality angled brush for precise cutting in. Consider using a repurposed half-gallon milk jug as a convenient paint container when working on ladders or moving around the room. Always keep a damp cloth at hand for quickly addressing any drips or mistakes before they dry.
