For many years grooved boards have been sold as a prevention to slippery surfaces. However this is not the case as layers of dirt build up in the grooves which then trap the water which then deteriorates the board and creating a slippery surface. As you can imagine this is difficult to clean out of the grooves so the problem is never solved. Timber is a natural product and will never come with a natural anti slip guarantee. We would recommend choosing a smooth surface profile as this will not be difficult to clean and will stay cleaner for longer. Yes there will still be a build up over time but this can be cleaned right off the surface and you won’t have the issue of trying to get into nooks and cranny’s of the board. If you desire the appearance of a grooved board, choose a shallow V groove profile.
