Window, door and floor trim

[snowdust2]

I want to put trim around the bottom of my shop to finish it off. I was thinking of using 1"x4" PVC and sealing the bottom with silicone before I set it in place. I also have two windows and a door to finish. I saw this from Home depot and thought maybe I could do the jam extensions and all the trim with it so it all matches. Thoughts?

Pvc is the good stuff for trim but your idea for installing it is a really bad idea. You need to use z flashing slid up underneath the siding and then install the trim board without caulk under the lip

Follow link shows a diagram. Another name for Z flashing is drip cap.

As far as windows and doors they really need flashed correctly and their is a lot of info on the web how to do so. Caulk is never used on the bottom side as it will trap water there and rot the walls.

My only comment is a caution. That pvc makes a really fine sawdust that sticks to everything. It doesn't wipe off your arm or clothing like wood dust does. I move my saw outside and wear a good respirator when cutting it.

Working PVC *****. PVC dimensions change based on temperature.

For similar money, look for Boral Truexterior trim boards. IMO, superior is every way except that it's more fragile while you're handling it.

Are you talking about the inside of your shop? Seems like everyone is commenting based on exterior installation and I'm thinking we're all confused.

If you're talking about baseboards for the interior I think that would be fine. Although I probably wouldn't seal the bottom, as that likely doesn't leave any path for mosture on the sill to escape since it's probably sealed from the outside as well.

Sorry guys.. I should have been more clear. I am referencing the inside. The thought on the seal on the bottom was to keep water from getting to the wall when washing cars and stuff. I get what you are saying on the moisture. The walls are just on the cement with sill foam down first. No other seal. I'm thinking I'll be ok to silicone the trim.

I used the Truexterior leftovers to trim out my windows and door on the interior. Easy to sand if you've got a joint that just won't go together perfectly. It takes paint really nicely.

When I'm done with the floor tile, I plan to run 1X PVC as a wall base. Due to the durability issue with the Truexterior boards.

Synthetic wood, be it Trex or Azec makes IMHO great trim.

Yea, if you're going to be washing cars in there and it's not sealed on the outside, I think your idea of PVC trim and sealed on the bottom is a good one. Should be just fine.
