It was above freezing during the day when I started this. The lady at the paint department warned me not to buy some exterior paint because she said that it needed to be over 40 degrees for 3 days. I thought I would do it in the sun room, which is 60 degrees during the day. I bought a roll of duck canvas at the Surplus City north of Altoona for $4.99 a yard. I decided to cut a piece and put it in the washer. I had added some extra length for shrinkage, but it shrunk 8 inches!! and it was terribly wrinkly. After reading some more, I tested the nice and wrinkle free canvas I had bought with some drops of water. They soaked right in, so I realized there wasn't sizing on it afterall
So I put the canvas on, glued it down with TBII but didn't cut it off the roll, for fear it would shrink terribly. It didn't shrink at all though. The glue must counteract the shrinking motion sufficiently. It ended up fairly smooth.
I found some white cinder block flat paint in the garage left from the previous owners. I used that for the first two coats. Then I used the grayish color I had purchased over the objections of the paint lady at Lowe's. The wrinkles all shrunk out. Beautiful.
