Here are some in progress pictures of a recent deck refinishing job in the Prospect Heights area of Santa Cruz.  I find it helpful to show different stages of the project, different times of day, drying times etc..  

Fifteen year old deck give or take.  We were told five years since the last bit of maintenance.  Dangerously slippery when wet.  Awfully mustardy in color we all agreed.  Deck gets medium to good amount of sun.
