On the ocean front sealing keeps salt from crystallising in the pores; under the Pittwater canopy it stops tannin soaking in; around the lagoons it slows algae. A re-seal is typically due every three to seven years depending on which part of the beaches you are in.

The Northern Beaches packs surf beaches, four coastal lagoons, the Pittwater estuary, Middle Harbour and national park bushland into one council area, so stone sealing is never one method for everyone. The table shows how we adjust it by condition and how often it is usually needed.

Conditions Suburbs What we are dealing with How often
Ocean-front and first-ridge Manly, Queenscliff, Freshwater, Curl Curl, North Curl Curl and Collaroy and 6 more On the ocean front a breathable penetrating sealer keeps salt water out of the stone's pores, which is what stops the surface powdering; expect a re-seal every three to four years here. a re-seal every 3 to 4 years
Lagoon and estuary Dee Why, Narrabeen, North Narrabeen and Warriewood Lagoon-side, sealing slows the algae by keeping water out of the stone, but it must be breathable so moisture from below can escape; film sealers fail fast here. a re-seal every 3 to 5 years
Pittwater waterfront and slopes Bayview, Church Point and Clareville On Pittwater properties sealing is mostly about tannin: a penetrating sealer stops leaf stains soaking into pale stone and makes the next clean far quicker. a re-seal every 3 to 5 years
Plateau and bushland edge Elanora Heights, Ingleside, Terrey Hills, Duffys Forest, Belrose and Davidson and 3 more On the plateau a penetrating sealer on paving and steps keeps moss and clay staining at bay; the drier air means a seal lasts longer, typically five to seven years. a re-seal every 5 to 7 years
Harbourside Middle Harbour Fairlight, Balgowlah Heights, Clontarf, Seaforth and North Balgowlah Harbourside, sealing sandstone stairs and travertine terraces cuts the regrowth of lichen and keeps the salt haze from soaking in. a re-seal every 4 to 6 years
Hillside and village Balgowlah, Cromer, Beacon Hill, Allambie Heights, Collaroy Plateau and Bilgola Plateau On the hillside homes we seal driveways, paths and pool coping with breathable products so they stay cleaner between washes for four to six years. a re-seal every 4 to 6 years

Our method in the Northern Beaches

How we do it, and what we protect while we work

Sealing happens at least 48 hours after cleaning, once a moisture meter says the stone is dry. Sealer goes on with a low-pressure sprayer, is back-brushed into the surface, and a second coat follows when the product calls for it. Any excess is buffed off so no haze is left.

Breathable products only on sandstone and limestone
Excess removed to avoid haze
Pool and garden protected
Dry weather window confirmed

Highly recommend The Prestige Standard, they cleaned my sandstone, it looks perfect!

Google review · Sandstone Cleaning

I recently had my brick pavers cleaned by Prestige Standard and I couldn't be happier with the results. The team was professional, punctual, and paid great attention to detail. My pavers went from looking dull and stained to fresh and almost brand new again.
