Do I have to reseal or restain my wood deck or dock after it is pressure cleaned?
Pressure washing breaks down the mildew in the wood and the chemicals kill it. They also open up the pores of the wood in the process. Therefore it is advisable to restain or reseal your wood deck after pressure cleaning it. This will help to preserve the wood for years to come. In Florida, you should consider resealing or restaining your wood deck or dock once a year anyway, because of the severe sun and moisture that it is constantly exposed to. Your alternative is to replace the decking more frequently, and not have as nice of a surface to enjoy.
