You might feel that an 18-year-old deck is beyond a little bit of enhancement in terms of safety - but Mark Byard's pressure treated softwood decking had originally been installed correctly by a professional installer and has plenty of life left in it.
Whilst Mark had always maintained his large deck area at the back of the house, cleaning it thoroughly every two to three years or so, lately he was increasingly experiencing a slippery problem during wet weather and wanted to do something about it. Mark regularly walks on his decking in all weathers as it is the only access to his rear garden and his waste bins.
There is always a risk that aged or unmaintained decking can become slippery in wet weather and this heightens the risk of slips and injury. The build -up of mildew, algae and fine mosses can cause a deck to become slippery over time, whilst the deck also needs to be correctly installed so that it drains freely and remains well ventilated. These measures will certainly help to slow down the development of a slippery deck, but further measures, such as adding an anti-slip enhancement, lessens the risk further.
