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.
Dalry
Dalry is a village in the Garnock Valley in Ayrshire, Scotland. Drakemyre is a northern residential area. Dalry (from Scottish Gaelic Dail Ruighe, indicating 'the haugh at the incline') is a little negotiation on the Rye Burn. Its history has indications of very early occupants in the area; the remains of an ancient fort, made of three concentric round walls, can be found on the summit of Carwinning Hill to the North of Dalry, west of the B784 to Largs.
