Rip sawing Pressure Treated 5/4' flooring.
I needed lumber to trim out a 15 year old ceder deck - it has rotted in spots (only a couple) along the sill against the house. I think was due to trapped water between the sill (on house wall) and the 5/4" decking, which comes in at a 45 degree angle.
I wanted to put a 5/4" by 4" (3.5") strip along the wall on top of the existing decking (again coming in at a 45 degree angle). I would then caulk the trim strip against the house wall to block further water entry - this may have been a better initial design.
My problem came up when going to Lowes and finding they did not have any 5/4" x 4" decking. So, I purchased 5/4" by 6" and need to rip it to narrow it down to the 3.5" range. I would also put a simple trim edge, maybe just a partial 45 degree edge.
My concern is running the pressure treated lumber through my 10" table saw. For one thing the lumber has a "wet" feel to my hand, and another I am concerned about the extensive handling, and saw dust.
I can wear disposable gloves and a simple breathing mask, and eye protection, is that enough?
Will this stuff rip any thing like untreated lumber, or will there be more tendency to bind? I will be ripping one 10' and 2 8' lengths to get the material I need. The trim is just along the house wall. The railing has 4"x4" end posts, so I'd like to cut the trim to match that where the trim buts up against the railing posts at the two wall ends of the deck.
