Give Deck Posts an Oil Treatment

Deck posts below ground will, sooner or later, begin to rot. Delay that process with a couple of inexpensive products and a little digging.

Remove perimeter dirt down to the concrete base. Fill a bucket with sand and cover with 30-weight motor oil. Mix in and fill around the posts. This will help deter decay, just as oil-based protectants are re-applied to surface woods.
