Was replacing some wall panel on the home. This is 4' x 9' with bat boards over 1/2" think foil insulation.

Before I went to buy everything, I took a lot of it down b/c I wasn't sure what was underneath and didn't want to make multiple store trips.

Get my list of materials, get to store and they didn't have the smooth finish 4'x9' wall panel I'd seen online (I misread the web site). It was order only. Unfortunately, the wall panels were already down and pretty torn up b/c of how they were attached to the wall so no putting them back on. It's going to rain tomorrow night so I pretty much had to do it this way b/c no one else had 9' tall smooth panels.

The only 9' panels they had in stock came with groves, which did not match my existing smooth wall. The grove side had some kind of primer/finish on it, the back side was unfinished (looks like OSB).

So my son and I just flipped the panels over and put them up. Covered all seams with 1 x 2 batts and caulked everything. Finished with 2-coats of primer and planned to put 2 coats of exterior latex paint over that.

this is the product

this is what I planned on using but out of stock

am I screwed here and I should rip it all down and replace it? It is actually under an 1-foot overhang so it's not going to have torrents or rain running down it, but still exposed.

Edit to be clear, I put the unfinished side out then put two coats of Kilz latex primer over it and plan to with two coats of Sherwin Williams latex super paint

Will review again at dawn but IF you also sealed the sides, then you are good for life.
Some builders prefer this to hardie

The sides would not be sealed even if I put it finished side out?

Edit, do you mean the ends of the board (the 3/8" ends).

I think the finished side of LP siding is just primed but the whole panel is treated so if you paint it with exterior paint should be good.

I'm having a hard time understanding what you did. Do you have a picture? Either way, LP siding is NOT like regular wafer board. I have actually put scraps of this stuff submerged in a bucket of water for a month and it never warps or absorbs water.

Now, with that out of the way, do you mean you put the wafer board side toward the elements outside? I'm having trouble envisioning your question but either way, smart siding isn't going to absorb water regardless of whether it's painted or not. It's a great product.

It's not really designed to be used osb side out and it's probably not going to be warranted if you need to but I dont think its going to be a functional issue.

One side of the panel is pre-finished with a primer coat. The other sides is not.

I just flipped over the wall panel so the primer side was facing the house and the unfinished side was facing out (it looks like OSB, but reading the description online it's not). I put 2-coats of latex Kilz primer on the exposed, unfinished panel and plan to paint it with 2-coats of latex paint.

I'm worried I made a huge mistake and will have to order the correct panel and redo everything.

I see.

The material is the same all the way through. The only difference is one side is pressed into a wood pattern, or batten pattern, and it's primed for paint. The other side will probably just have a smooth and dimpled appearance and be unprimed from manufacturing. But if you have primed it or painted it, it won't rot or give you any trouble. The entire product is a wood product that is bonded with proprietary waxes and resins and who knows what else. It is not going to absorb water, swell, or otherwise cause trouble in my opinion. It just will look like it's backward, because it is.

How many sheets are we talking about?

Q: What is the requirement for priming and/or painting field cuts?
A: All wood substrate that is exposed to the weather must be sealed in a manner that prevents moisture intrusion and water accumulation: 1) Seal ALL exposed cuts of siding and trim. Field spray applied coatings on cuts are NOT recommended. 2) Sealing can be accomplished by applying a coating (paint) or sealant (caulk) according to their manufacturer's requirements. 3) Butt joints that are covered with joint molding, sealant, or factory Prefinished end are considered sealed from the weather.

Good to go
Next project is .....?

I read that as well, but wasn't 100% sure it was all a engineered product and thought I'd shot myself in the foot.

The next project..

..this is actually the beginning of the kitchen remodel, which is starting in the laundry room. There was an outside door in the laundry room that's been used maybe 10-times in the 12-years I've lived in this house. We always use the patio door but wife wants a 2nd fridge upstairs instead of the basement and the best location is where the door used to be. So door is gone, outside wall is in place and primed.

Next is add an outlet and water line for the fridge, put back the insulation where the door hole used to be, drywall and primer. Then configuring the new cabinets, sink and counters in the laundry room, get those on order, put a new window over the sink (laundry currently has a small sink, wife wants a larger one).

Once that is all done, we move onto the kitchen which is in the planning, scheduling, list of materials phase in December.
