A brush is better for pushing both the dye and oil along the decking grooves and getting it into corners and details. A liberal coat of oil should be applied initially, which will take a while to soak into the Driftwood. Wipe off any excess the following day. 1 or 2 coats should be sufficient, but further light coats can be applied annually after gentle cleaning. Best to wash down with a soft broom when required rather than using a pressure washer.
