Interior Paneling Gaps

[dmschellaz99]

I’m working on lining my trailer interior with 1/8” Baltic birch plywood sheets. In each of the corners where sheets come together it’s difficult to get the gaps perfect and I’m looking for ideas on how to cover these gaps.

I don’t like the idea of using a quarter round wood trim as it seems kinda bulky. I’m thinking some sort of caulk but can’t find any caulk in the right color to match the birch. Any ideas?

Is this the wall/headliner joint? How big of a gap? 1/8"?

I used birch plywood for the ceiling and knotty cedar for the walls. I covered the gaps with strips of pine.

Yeah I actually built my trailer out of 1”x1” steel tubing so I have to sheet the interior steel/foam insulation. The gaps vary and are about 1/8” to none based on how good I got with cutting the interior panel.

Mask up with electrical tape, as narrow as possible. Caulk with either white or black Sikaflex 252, tool it in real tight, and peel the tape while the caulk is still wet. Make it a bit of a feature. Practice on scrap first.

I made some flat molding to cover the gap where the canvas didn't quite meet the walls on the headliner. It's thin enough to take the front curve (a 30" radius in my case). The headliner was good when it went in place & formed well enough, but the 5' wide canvas was only 58" wide. This stuff would be similar to the flat molding sold in lumber yards as "screen molding" used to cover the joints in a screen door, if they still make that type now...

one possible solution could be from the upholstry industry

WELTING

a piece of cordage(3/16" in this case would cover your 1/8" gaps) wrap'd in a vinyl or fabric that compliments the build

older cars and some more modern builds use it between bolt on components

American LaFrance used welting between the side boxes and main tank enclosure on my '64 firetruck
