Well I hate to admit it but I actually couldn't find a good almost free source for plywood so I had to bit the bullet and spend $120.00 for 6 sheets of 3/8 a/b interior for the ceiling. I need to get it installed before the remaining drywall is put in place to allow the drywall to help support the ceiling. I also picked up another 2 gallons of polar seal.Total out the door was $160.00 +/-
I love the polar seal it is like putting on a rubber wet suit for the siding. I want to coat the zip panel with it to help seal the joints and waterproof the entire surface, I will give the joints extra attention and may even go back with silicone if the polar seal doesn't fill in as well as expected. The weather is 70's- mid 80's today and the humidity is down so it should be a good afternoon to get 'er done.
