Water blasting, or pressure washing, can effectively clean your deck by removing dirt, grime, and mildew. Here’s a general guide:
Preparation: Clear the deck of furniture and sweep away loose debris.
1. Select Appropriate Pressure: Use a pressure washer with a fan tip nozzle and set it to low to medium pressure to avoid damaging the wood.
2. Test a Small Area: Test on an inconspicuous spot to ensure the pressure isn’t too harsh.
3. Maintain Proper Distance: Hold the nozzle about 30 centimetres from the surface.
4. Even Strokes: Move the nozzle in smooth, overlapping strokes following the wood grain.
5. Post-Cleaning: Allow the deck to dry completely before applying any sealant or stain.
Note: Improper use of a pressure washer can damage your deck. For optimal results and to protect your investment, consider hiring professionals like Diamond Spec Pressure Washing.

3. Apply Detergent: Use a detergent designed for house exteriors, applying it from bottom to top to prevent streaks.
4. Pressure Washing: Rinse from top to bottom with a suitable nozzle, maintaining a consistent distance to avoid surface damage.
5. Avoid Windows and Vents: Be cautious around windows, doors, and vents to prevent water intrusion.

When performed correctly, water blasting is safe for concrete surfaces. However, potential risks include:
– Surface Etching: Excessive pressure can cause etching or lines on the concrete.
– Sealant Removal: High pressure may strip away sealants, making the surface more susceptible to damage.
– Aggregate Exposure: Improper technique can expose the aggregate beneath the concrete surface.
Recommendation: To prevent damage, it’s best to use professional services. At Diamond Spec Pressure Washing, we adjust pressure settings and techniques to suit each surface, ensuring effective cleaning without harm.
