The Dura Deck Tile Resist range includes edge ramps to provide a neat transition between the decking area and the adjacent floor surface, and corner ramps which help finish off external corners. If your deck design requires internal corner edge ramps, you can create these yourself, but we would only recommend this if you’re an experienced DIYer with the necessary jigsaw or mitre saw and a good understanding of cutting and measuring. If you want to do this, you should first remove the straight edge plank from its in-built base, cut it to the 45 degree internal corner, then cut to length to suit the external corner base (which is shorter than the straight edge) and then repeat for the opposite side. You can then reattach to the plastic base. If you require further technical support, please get in touch.
