The key factor in preventing slippery decking is to ensure that the deck surface is kept clean and surface deposits such as mildew, algae and fine mosses are kept at bay. It is these deposits that cause slipperiness on any surface; even stone flags in wet weather.
Remember also that wet weather can be experienced throughout the year and so slippery decking can be a year round issue if you don’t manage your decking correctly.
We would recommend that you frequently brush your decking with a good quality, stiff brush to remove dead leaves, dirt and moss. You should also give decking a thorough clean at least annually, using a specialist decking cleaning product and either a scrubbing brush or pressure washer. This is usually undertaken during the spring or autumn.
Regular cleaning and maintenance such as this will certainly help to reduce slippery decking. TDCA members produce a range of deck cleaning, maintenance and decorative products to help keep decks looking good.
A further precaution to slippery decking is to choose an anti-slip decking product when you first construct your timber deck. There are many designs on the market, the most common seeing the timber deck enhanced with a grit and resin formulation that sits in some of the grooves in the board, offering a reassuring grip. The enhancement is subtle and does not detract from the natural charm of the timber.
Alternatively, there are anti-slip decking products that can be fitted retrospectively, should you wish to add the safety feature to decking that is already laid. A number of TDCA members offer such products, which generally fix into the grooves or the boards or are screwed to the surface. This might be applicable for high risk areas such as steps and walkways, or much larger decking surfaces. The products are easy to fit and provide a long-lasting solution to the worry of slippery decking.
