When it comes to painting any commercial or industrial facility, proper surface preparation is just as important as the paint itself. Dirt, grime, mould, and peeling paint can prevent proper adhesion and compromise the final result.
That’s where professional pressure washing comes in.
At Precision Cleaning, we help businesses and organisations across Canberra and beyond prepare their surfaces for painting the right way—ensuring a long-lasting, high-quality finish and protecting your property investment.
Why Pressure Washing Before Painting Is Essential
Before applying any new coat of paint—whether on walls, facades, fences, or external structures—it’s crucial to start with a clean, contaminant-free surface. Over time, exterior surfaces accumulate:
- Dust and dirt from traffic or the environment
- Mould, algae, and mildew, especially in shaded or damp areas
- Flaking paint or chalky residue from UV damage
- Oil, grease, or industrial fallout in commercial settings
Skipping the cleaning stage can lead to:
- Poor paint adhesion
- Uneven finishes or bubbling
- Premature paint failure
- Increased long-term maintenance costs
By pressure washing beforehand, you’re not only removing these issues—you’re extending the life of your new paint job and ensuring the surface is prepped to professional standards.
Our Proven Pressure Washing Process for Painting Preparation
At Precision Cleaning, we follow a structured process to prepare your surfaces thoroughly and safely.
1. Site Assessment and Material Evaluation
Before starting, we inspect your property to:
- Identify paint flaking, mould growth, or damaged substrates
- Assess surface materials (concrete, timber, brick, metal, render)
- Choose the right pressure, technique, and eco-friendly detergents

2. Surface Cleaning with Targeted Pressure
We use hot or cold water pressure washing, adjusted according to the surface type and contamination level. For example:
- Concrete walls: Medium-high pressure with rotary nozzles
- Timber surfaces: Low pressure to avoid damage
- Render or painted surfaces: Gentle rinse after a soft chemical wash

3. Detergent Application for Stubborn Contaminants
For areas affected by mould, mildew or greasy buildup, we pre-treat with a biodegradable solution that breaks down biological growth without damaging your property or landscaping.
This is especially valuable for healthcare centres, retail buildings, and educational institutions, where hygiene and environmental safety are critical.
4. Rinsing and Drying Time
After the pressure washing, we rinse all surfaces thoroughly and allow appropriate drying time before any painting begins. This ensures optimal conditions for paint bonding and prevents trapped moisture from affecting the new coating.
Benefits of Professional Pressure Washing Before Painting
- Improves Paint Adhesion – Surfaces are clean, dry, and ready to bond with primer and paint
- Extends Paint Lifespan – Removes harmful contaminants that break down finishes
- Saves Time and Labour – No manual scrubbing or sanding needed on most surfaces
- Promotes a Uniform Finish – Reduces the risk of bubbles, streaks, or inconsistent colour
