Hello!
I have a newly built brick wall that should be fitted with sheet metal on the top of the wall. The metal has a profile with a flat top and goes down the sides about 5cm with an outward-angled drip nose. But I'm not quite sure how the metal should be attached to look neat and work well over time. I have received a few different options: nailed, screwed, mounting adhesive, or foam sealant.
- Nail: It might be possible to drive nails (steel nails?) into the mortar joints. But it might not look very nice and there's a risk of slipping with resulting damage? Maybe the mortar will crack?
- Screw: Drill, plug, and use farm screws? This might easily cause deformation of the sheet metal sides when tightened?
- Mounting adhesive: Yes, then it will probably stay on forever without being able to remove the metal. Probably needs a dry surface.
- Foam sealant: Initially sounded "foamy," but apparently, it works well to spray on (even on a damp surface) and then spread out before laying the metal on top. It will certainly hold well once cured.
Grateful for input on the different options and experiences.

Checked how a real plåtslagare did on a similar wall. First, he drilled and plugged, screwed down a lower sheet which he then seamed the upper one into. This way, he got a completely hidden installation and no ugly screws that leak water into the wall.
