Preparing Your Walls for Painting | Expert Step-by-Step Guide QLD
Prepping your walls properly is essential for achieving a long-lasting, professional finish. Dust, old paint, mould or cracks can affect paint adhesion and appearance. Without thorough preparation, even the highest quality paint won’t perform as expected. That’s why painters across Brisbane, Gold Coast, and beyond start every project with a detailed prep process.
Inspect the Surface
Before you begin, assess the condition of your walls. Look for peeling paint, water damage, holes, or surface imperfections. These issues will need to be addressed before any paint touches the wall. For more complex restoration needs, QLD Electrostatic Painters provides professional Repainting & Restoration services in QLD to revive tired walls and get them paint-ready.
Clean the Walls Thoroughly
Clean walls help paint stick better and prevent blemishes. Use a mild detergent with warm water to wash off dust, grease, and grime. For kitchens or high-traffic areas, a degreaser may be necessary. Rinse with clean water and let dry completely. If you notice mould or mildew, consider using an Anti-Mould Wall Coating after cleaning to prevent regrowth. Clean walls create a solid base that ensures even coverage and better finish quality.
Repair Holes and Sand the Surface
Patching and sanding are critical. Fill nail holes, cracks or dents using a filler or putty. Once dry, sand the surface until smooth using fine-grit sandpaper. Pay special attention to glossy areas or previously painted sections — these may need a light sanding to help the new coat bond. If you’re painting over textured walls, it’s worth checking our Wall Surface Preparation services in QLD. Once all imperfections are addressed and the surface is even, remove all dust with a vacuum or damp cloth before moving on to priming.
Tape and Protect
Use painter’s tape to mask off skirting boards, windows, and trims. Drop cloths or plastic sheeting will protect floors and furniture from splashes. This step is often rushed but makes a huge difference in keeping the job neat. Taking the time to tape properly now saves hours of clean-up later and guarantees crisp lines.
Apply a Quality Primer
A primer seals the surface, evens out porosity, and ensures your chosen colour appears true and consistent. This is particularly important if you’re painting over dark or patchy walls, or moving from a glossy to a matte finish. For freshly repaired areas or porous walls like plaster or brick, priming is non-negotiable. If you’re painting in regions like Toowoomba or Ipswich, local climate conditions might also influence the type of primer best suited for your job. QLD Electrostatic Painters can help choose the right product for your environment.
FAQs
Q1. Can I paint over mould-affected walls?
You shouldn’t paint over mould without treating it first. Use a mould remover and consider an Anti-Mould Wall Coating to prevent recurrence before applying any paint.
Q2. Do I need to prime if my walls were already painted?
If the existing paint is in good condition and you’re using a similar colour, priming might not be essential. However, it’s highly recommended when changing colours or painting over patched areas. Learn more in our Wall Surface Preparation Guide.
