A Quick Guide to Cleaning Exposed Aggregate Around Pools

Exposed aggregate is a popular choice for pool surrounds because of its textured appearance and durable finish. However, the gaps between stones can collect dirt, sunscreen residue and organic growth. In Glenelg, coastal sand and salt spray can also add to the cleaning workload. Regular, gentle cleaning helps keep the surface looking good and reduces slippery buildup.

Check the Surface Before Cleaning

Look for loose stones, cracks, worn sealer and patches of algae before you begin. Cleaning cannot fix damaged concrete, and aggressive pressure washing can make existing problems worse. If the surface is newly installed or recently sealed, follow the installer’s curing and maintenance instructions before applying cleaners or using pressure equipment.

How to Clean Exposed Aggregate Around a Pool

1. Remove loose debris. Sweep away sand, leaves and grit with a stiff nylon broom. Avoid wire brushes, which can scratch finishes or leave metal particles that rust.
2. Prepare the area. Move furniture and pool accessories, protect nearby plants and plan how you will collect wash water. Keep dirty water and cleaning products out of the pool.
3. Apply a suitable cleaner. Choose a pH-neutral product labelled for concrete and compatible with any existing sealer. Test a small, inconspicuous area first and follow the dilution instructions.
4. Scrub and rinse. Work in manageable sections with a nylon brush. Allow the recommended dwell time without letting the cleaner dry, then rinse thoroughly using controlled amounts of water.
5. Inspect once dry. Check for remaining slippery patches or stains before returning the area to normal use.

Use Pressure Washing Carefully

More pressure does not necessarily mean a better clean. A concentrated jet can dislodge aggregate, erode the cement between stones or strip sealer unevenly. Start with the least aggressive method recommended for your surface. If pressure washing is suitable, use a broad fan spray, test a hidden section and keep the nozzle moving at a consistent distance. Avoid turbo nozzles and close-range blasting.

For extensive algae, fragile surfaces or unfamiliar coatings, a professional cleaner can assess the finish and select appropriate equipment.

Treat Stains Without Damaging the Finish

Algae and Organic Buildup

Use a treatment specifically labelled for outdoor concrete and compatible with your sealer. Follow safety directions, including protective equipment and plant protection. Never mix bleach with acids, ammonia or other cleaning products.

Rust, Oil and White Deposits

These stains need different treatments. Use a concrete-compatible degreaser for oily https://troyaeyu558.oakridgedigest.com/posts/revive-your-weatherbeaten-timber-pergola-with-jet-washing residue and seek advice before treating rust or white mineral deposits. Avoid household acids and improvised acid washing: they can etch the cement and damage nearby pool fittings.

Manage Runoff and Ongoing Maintenance in Glenelg

Do not hose detergent, sediment or chemical wash water into street gutters or stormwater drains. Check current City of Holdfast Bay and EPA South Australia guidance when planning runoff collection and disposal. A cleaning contractor should explain how wastewater will be contained.

Sweep regularly, rinse coastal deposits when needed and address algae early. Check the sealer’s condition rather than resealing on a fixed schedule. If resealing is required, choose a product suitable for exposed aggregate in wet pool areas, with appropriate slip resistance. A glossy finish alone is not a sign of a safer surface.
