Travertine sealing in the Eastern Suburbs
Salt-chlorinated pools and sea spray push salt into travertine, and as it dries the crystals break up the surface. A penetrating sealer chosen for salt is the most effective protection.
When travertine coping turns pitted or sugary along the pool edge, salt is the usual culprit, not wear. In the Eastern Suburbs that salt comes from two directions: the pool itself, which is often salt-chlorinated, and the air, which on the clifftops at Dover Heights, Tamarama and Coogee carries ocean spray well back from the edge. Harbourfront terraces in Point Piper, Vaucluse and Darling Point get a milder version from the water below. Unsealed travertine soaks up that salty water through its pores and natural holes, and every hot, dry afternoon grows more crystals inside the stone. Sealing does not make the stone immune, but it slows the cycle a great deal.
Our sealers are impregnators formulated for limestone in salty conditions. They line the pores rather than forming a film, so the surface keeps its texture and grip underfoot, which matters around pools with children. Water, salt water, sunscreen and food oils sit on top long enough to be rinsed off. For a richer tone, an enhancer can deepen the warm and grey colours found in many travertines. We test that on your own stone first, because enhancement stays until it wears. Glossy topical coatings are what cause slippery, cloudy pool surrounds, and we don't use them outdoors.
Preparation decides how long a seal lasts. The stone is cleaned to bare surface with acid-free products, open holes are refilled with a colour-matched filler, and the area is left to dry properly. Travertine beside a pool holds water, and harbour-side gardens can stay humid, so moisture is checked before any sealer is opened, whatever the schedule says. Sealer is applied in measured coats and any surplus is taken off before it dries. We then give you cure times for foot traffic, furniture and swimming, record the product used, and suggest a yearly water-drop test, with re-sealing when drops stop beading.

Travertine cleaning & sealing by suburb
Frequently asked questions
Straight answers from our stone-care technicians.
How often should travertine around a salt pool be re-sealed?
More often than sheltered paving. Check it every year with a water-drop test, especially along the waterline edge. On clifftop sites with ocean spray as well as pool salt, the interval is usually shorter again.
Can you seal travertine on a balcony above the beach?
Yes, if the stone can be cleaned and dried properly and we can protect the surroundings. Balconies in strata buildings are often common property or have by-law rules, so check with your strata manager first.
Will sealing fix travertine coping that is already flaking?
No. Sealing slows further damage but cannot rebuild lost surface. Badly spalled pieces may need honing, patch repair or replacement before sealing. We tell you which pieces are worth saving.
When can we use the pool again after sealing?
Cure time depends on the product, and we confirm it on the day. As a rule, allow at least 24 hours before swimming or walking on the coping, more in cool or humid weather.
