Sanding to refresh decking

 If the deck is stained or oiled and needs minor repairs, sand it first then give it a good clean with a pressure cleaner to thoroughly prepare the surface for refi nishing.If the deck has been painted and needs to be prepped, use a random orbital sander fitted with an 80 grit disc, working across two boards at a time to make your way across the deck.

 

TIP If the nail holes were filled and the putty has popped out, refill and lightly sand with 180 grit abrasive paper.
