Drywall and Stem Wall

[brew_and_tinker]

Hello Fellow Garageinistas,

I recently had my attached garage floor epoxy’d, including the 4” stem wall. Then had the walls insulated and drywalled. Mudding and sanding is complete and I plan to prime & paint (myself) soon.

The base of the drywall is not flush with the stem wall— it sticks out about a half-inch over the stem wall.

Is there some type of trim available that would protect the bottom edge of the drywall and would allow me to caulk the trim to the stem wall? I do not want to install a base board if possible. Just finish the edge of the drywall and seal so moisture/bugs dont get up behind the drywall. Cove base isn’t really appropriate here.

The closeup photo is me laying on the floor attempting to shoot up and show the edge I’m trying to seal.

Thanks!

The floors look pretty and depending on your use and the appearance criteria you're looking for...
I'd put a simple 1x6 "mop board" down to the floor and paint it. You might need a little filler at a doorway but inside and outside corners will be fine. I'm assuming that you can fasten it to your plate or framing within the normal 5 1/2" ×/- of a 1x6.

A little challenging - trim but not base board - what about a wood corner bead? Rip one leg to allow it to sit tight.

I swear I've seen this vinyl, but couldn't find it on line. Outwater.com is down for maintenance - my usual source for odd plastic materials.

Maybe fur out the stem wall at the base and use traditional baseboard?

That edge could have had a J bead put on it when the board went up. (Vinyl or metal.) Harder to do now.

If the OP really do not want to see a moulding I would still try to put one behind.
Cut a slot between the wall and the drywall with utility knife or if you have a multi tool would work perfectly so a metal tile profile can be pushed in.
Put some sealant in there and push the metal profile in there and if needed secure it with blue tape.

Thanks everyone for your input. Might be too late to use J-trim, and I don’t want to install baseboards. I wish there was a vinyl or other flexible trim that could “stair-step” over the protruding edge and rest up against the stem wall giving me a place to seal up any gaps up behind the sheetrock

Maybe some outside corner moulding,,,

How about something like this: Z Flashing

L metal is used more often on raw drywall edges.

One of those guys who does form it on the job gutters could make you a custom Z flashing. Or some siding guys use aluminum to cover 2x8s and 2x10s w/ aluminum when they do a porch roof. My house has a lot of that.

I know you have said no, but for a garage I would have use 1x4 PVC boards for a baseboard.

I would use one of these shadow beads. https://www.trim-tex.com/products/architectural-z-shadow-bead

The plastic trim will rest down on the epoxy and will give you a clean plastic trim/line that will take the same paint as the wall.

Sometimes the more you "mess" with very slight design oversight the more attention you draw to it and the cure is not any better.
In one of your pictures the slightly different lengths of the drywall appears to be the only "eye catcher" and if that's carefully trimmed up it'll look fine especially only an inch or so above the floor.
The drywall is not going to crumble away and a tiny gap between it and the stem wall is irrelevant in a garage.

OP - I know you said you didn’t want base molding, but pvc 1x4, 1x6 or similar would be ideal.
