Travertine cleaning and sealing in Clareville

A travertine pool terrace in Clareville works hard. It takes salt from the pool, humid air from Pittwater and strong afternoon sun on the west-facing side of the peninsula. Salt water soaks into the stone and leaves crystals as it dries, gradually roughening the coping and opening up the natural holes. Leaves from garden trees add tannin stains, and sunscreen and food leave greasy marks around outdoor furniture. Because travertine is a form of limestone, the most common household and pool-shop cleaners, many of them acidic, can do lasting damage. Our technicians start by identifying which marks are dirt, which are stains and which are etching, so you know what to expect.

We clean travertine with alkaline products made for limestone, never acid. Soft brushes push them into the holes, a rotary machine at low speed works the surface, and a low-pressure rinse finishes the job. Grease and tannin that remain get a targeted poultice. Protection comes first: a pool cover, blocked skimmers and sheeting over nearby timber decking, outdoor furniture and garden plants. Afterwards our vacuums recover the rinse water, so the pool and the bay below stay clean. Etched or dull patches from earlier acid use are pointed out, because they need honing rather than cleaning, which is a separate service.

When the terrace is clean and dry, we refill open holes with a matching filler, then apply a salt-tolerant impregnating sealer a little at a time, removing any surplus before it can cure on the surface. That keeps the travertine's texture and grip and slows salt and stains from entering. On hot west-facing terraces we seal in the morning or on a milder day so the product cures evenly. We confirm curing times before swimming, record the products used, and suggest checking the coping every summer: if water darkens the stone instead of beading on it, the sealer has worn and it is time to reapply.
