When it comes to sealing or painting outdoor surfaces like concrete, pavers, brick, or stone, proper preparation is everything. Skipping the prep or doing it poorly often leads to coatings that fail prematurely, costing you time and money to redo the job. One of the most effective ways to prepare surfaces for sealing or painting is with professional pressure washing.

Why Surface Preparation Matters

Sealers and paints rely on strong adhesion to the surface. If there’s dirt, grime, old coatings, or embedded contaminants in the way, the new sealer or paint won’t bond properly. This can result in:

• Flaking or peeling coatings
• Uneven colour and patchiness
• Trapped stains reappearing through the finish
• Reduced lifespan of your sealer or paint

Thorough cleaning is essential to give the surface a fresh, contaminant-free foundation.

How Pressure Washing Helps

Unlike regular scrubbing or hosing down, pressure washing uses high-powered water (and often hot water) to penetrate deep into porous surfaces like concrete and pavers. It flushes out dirt, grime, and stains that sit both on top and within the surface.

Professional pressure washing goes further by removing:

• Oil and grease residues that prevent sealers from adhering
• Mould, moss, and algae that can keep growing under a coating
• Efflorescence or lime deposits that cause patchy results
• Old sealer residues that need to be stripped before reapplication

By starting with a truly clean surface, sealers and paints can bond properly, giving a smoother, longer-lasting finish.

Hot Water and Specialist Cleaning Solutions

At The Stain Eaters, our custom-built pressure washing systems give us the ability to deliver both hot and cold water cleaning. Hot water pressure washing is especially effective at breaking down oil stains and grease, speeding up the cleaning process and giving better results.

For tougher stains like rust, paint spills, or efflorescence, our technicians use specialist cleaning solutions formulated to safely break down these contaminants without damaging the surface. This ensures the area is thoroughly prepared before sealing or painting.

Why Use Professionals

DIY cleaning might make the surface look better, but it often leaves behind residues that can still interfere with adhesion. Our trained technicians know how to assess the condition of each surface, choose the right cleaning method, and prepare the substrate properly for sealing or painting.

With decades of experience and the right equipment, we ensure that your investment in sealing or painting lasts for years to come.
