Travertine cleaning and sealing in Whale Beach

Pool decks and terraces in Whale Beach are usually set out to face the view, which means they also face the weather. Onshore wind pushes spray up the slope and over the deck, pool water dries along the coping in the afternoon sun, and the salt left behind crystallises inside the stone. On a site like this, the nose of the coping and the terrace edge closest to the ocean tend to pit and flake first, often within a few years if the stone was never sealed. Sand walked up from the beach scours the surface, and the sheltered corners behind glass balustrades and walls are where mould gathers.

Before anything else, our technicians check the coping by tapping along its length, because on exposed pools salt can loosen the bedding beneath, and any hollow-sounding piece needs to be fixed back down by a tiler or pool builder before it is cleaned and sealed. Cleaning itself is acid-free: once loose sand is blown away, a limestone-safe alkaline cleaner goes down and soft rotary pads scrub the face and the holes. Rinse water is captured on the deck instead of running down the hillside, and the pool stays covered. If acid from an earlier cleaner has left etch marks, honing can bring the surface back to an even finish.

With so much exposure, the sealing day is chosen as carefully as the sealer. We wait for dry stone and a still forecast, since onshore wind lays salt and grit on fresh product. Open holes are packed with a filler matched to the stone's tone, and an impregnator formulated for salt water is worked into the surface in thin coats, with any surplus taken off before it dries. The deck keeps its natural texture and grip. Plan on an inspection and water-drop test each year, beginning at the waterline and the ocean-side corners, and re-seal those parts first once drops soak in.
