For the chairs, he sanded the seats really well and scuffed the legs and backs. We used painter's tape to tape off the seat and sprayed the tops and legs of the chairs with the black spray. After it dried we removed the tape and newspaper from the seat and stained it the same color as the table and bench top.
Now for the varnish...he varnished the top of the table with 4 coats to make sure that you could eat and drink on it without leaving water marks. He varnished the chairs and bench seat with one coat each.
