Step Three: Install Your New Board

Step Four: Admire Your Work

That’s all there is to it! Your new board might still look a little mismatched at first, but don’t worry – it’ll smooth out over time. If you want to hurry the process along, oiling and staining your decking will help bring all the boards to a smooth, even colour.
