Usually, slipperiness is caused by algae or dirt on top of the deck or terrace. A full cleaning treatment should restore the natural grip of the wood or stone. If slipperiness is a persistent problem, consider installing grip mats in high traffic areas of the deck.
Lochailort
Lochailort is a district in Scotland that exists ahead of Loch Ailort, a sea loch, on the junction of the Road to the Isles (A830) in between Ft William as well as Mallaig with the A861 in the direction of Salen and Strontian. It is served by Lochailort railway station on the West Highland Line. Nearby is Lochailort Inn, a pub, and Our Lady of the Braes, a tiny Roman Catholic church that was consecrated in 1874 but little pre-owned since 1964 as Sunday Mass is celebrated in the church at Inverailort House which lies on the opposite side of the loch.
