5/4 Decking Boards for Trim?

[karoc]

I’m sure I’m not first to ask this or come up with idea. But?
Talking about treated 5/4 thick boards that normally use for decking. I want to install a skirt board or belly board around living space to kinda help separate it from garage. I also like to use it as trim boards both on corners and around windows. While at HD( just looking) I was able to find some 16’ ers with little or no knots. Just need to let them dry to see it say straight or not or maybe cut around them. I was also going to use oil base primer once dry out. Living space going to be Board Batten and garage going to be lap siding. So thicker wood would be nice. Wondering if anyone has done this with regrets or happy with results?

Drying them straight would be my biggest concern.

While I have not done this myself I do not see any issues and I can see me doing that myself too.

One just need to use appropriate fasteners.

My house has them around the garage doors.

Looks exactly like 5/4 deck boards painted white. The radius corner doesn't work for trim IMHO.

Agree it's nice to have that reveal with 5/4 and lap siding. I think you'd be better off putting 3/8 ext ply behind 4/4 trim boards. I have done this and liked the look just fine. Still looked good after 10 yrs when I sold. In Chicagoland area

I would strongly recommend looking at 5/4 LP trim instead

The radiused edge doesn't look good against the flat wall. It will look like a gap and trap dirt. It also makes it more difficult to mark/measure and make clean miters. If I did it I would plane that side.

That is the caulking gap.

That is the caulking gap.

The carpentry equivalent of weld prep

I built a couple of garden benches from 5/4 cuz i wanted full 1” boards. Worked well. I think every one got ripped to width, so the pre-radius edge wasn’t an issue.

I look at LP website seems most places carry lap siding and 1x4x3/4 but nothing else. Website said HD carry’s LP but they don’t. So sent email asking who carry’s all their products. I also sent email asking if lumber yard I been purchasing materials from if they could order LP products. Guys thanks for all suggestions

MiraTec would be another option.

That's a good suggestion. I've been trying to figure out the best way to deal with this after replacing the siding on the detached garage. Was going to pick up 2x lumber and plane it down, then thought 5/4 would work but shimming trim out makes a lot of sense.

Try a building supply. I get mine at ABC

I ripped the radiused edges off with my table saw

Yes, I have used it for window and door casing. Works excellent for the sides where you need 4 1/2" wide boards, just rip off the radius edges. The head casing where I needed 5 1/2" boards I left the radius and it's not too bad.

Some deck boards are thicker and not what you want. I was able to buy some that measured right at 1 1/8" thick and clear. Yes they need to dry a bit before paint.
