How to seal joint between siding and slab?

[m32825]

I've got a spot where the metal siding on my detached garage is trimmed back for a walkway/steps between it and the house. I want to do something to seal the joint between the trimmed part of the siding and the walkway underneath it. Goal is to keep debris out of the joint and prevent water intrusion when it rains. Would Sikaflex Concrete Fix be a good choice for this application? Thanks!

I would think you might want to keep that joint open in order to let moisture/water out, and not have it get trapped behind the siding.

Kind of like why you don't caulk/seal the joint/small gap between the siding of a house and the drip edge on the top of a window.

I agree.. you want there to be a water plane behind to allow moisture to come down the wall and drain out. You would only seal the OSB/plywood to the concrete to not allow moisture into the building.

Thanks for the feedback, guys. I love this forum because when I ask a question I often find out the more important question I should have been asking all along!

The longer term plan is to enclose this area, but until that happens it will see rain. Actually, it's been seeing a lot of rain lately, so some priority adjustment is in order.

Imo, from what I see, first unless the flatwork concrete plane is sloped away from the wall there is no hope other than slowing it down.

If there is that slope a piece of trim coil bent in an "L" shape could give some more ability to deflect the water away from the joint.

If you find the need to space the wall plane outwards, I would use something completely rot-proof like Azek. You can always cover that with the trim coil.

I would at least put a J channel along the walkway to make the siding look finished.
