Yes, you can pressure wash many resin-bound driveways if the surface is sound and the installer’s aftercare guide allows it. Start with a broom and a garden hose. If more cleaning is needed, use the lowest effective setting, cold water and a wide fan spray. Test a discreet patch and let it dry before doing the rest.
Check what type of resin driveway you have
On a resin-bound driveway, the aggregate is mixed with resin before it is laid. A resin-bonded finish is made by scattering stone onto a layer of resin, and its aftercare can differ. If you are unsure which you have, check the installation paperwork or ask the installer. A photo alone may not be enough to tell.
How to clean a resin-bound driveway
- Inspect the surface when dry. Look for cracks, loose stones, raised edges and old repairs. If the surface is shedding aggregate or lifting, ask the installer to assess it before washing.
- Sweep and rinse first. Clear leaves, grit and loose dirt. For light soiling, a garden hose may be all you need.
- Check the aftercare instructions. The Daltex aftercare guide specifies cold water and a fan jet for its system. Follow your own installer’s limits on pressure and lance distance, especially if the driveway is under warranty.
- Test one inconspicuous patch. Start on the lowest setting and keep the fan moving. Avoid concentrating the jet at edges or repairs. Let the patch dry and compare it with the area around it before continuing.
What about moss, algae and oil?
For green growth, start by sweeping away wet leaves and note where it keeps returning. Shade and damp can help explain the pattern. Our guide to why driveways turn green covers the common causes. If a cleaner is needed, choose one explicitly approved for your resin system and follow the label.
For fresh oil, blot up what you can and check which cleaners your installer approves. Avoid solvents, which may damage the binder. Our guide to removing driveway oil stains has a separate section for resin-bound surfaces.
When should you stop and ask the installer?
Stop if stones loosen during the test, the surface is lifting, or a crack is widening. Also ask the installer about persistent puddles on a surface designed to drain through. A closer jet will not repair a damaged surface or diagnose where the drainage problem lies.
Frequently asked questions
What pressure should I use?
Use the limits specified for your own driveway and start at the lowest effective setting. A machine’s maximum rating is not a cleaning target. Nozzle type, distance and surface condition also affect how forcefully the water hits.
Can I pressure wash a newly laid resin driveway?
Ask the installer when washing is permitted. The curing and aftercare instructions for the system they fitted should guide the timing.
Can I use a turbo nozzle?
Use the nozzle specified in your aftercare guide. If it calls for a wide fan, avoid substituting a concentrated rotary jet.
