Hi there

I have a metal building and the people who had it built didn’t use any foam closure strips around the base. Bugs come in through there and light and grass. I’m trying to fix it and I have foam closure strips but it’s going to be a pain to undo all the screws and place the closures in there. Friend of mine who does construction says to use cement leveler and pour it in there so it fills in the gaps. What are your thoughts on this? It’s way easier and I won’t have to worry about the r panels being super flush against the foam. Here is a picture of the issue.

Fill the holes with expanding foam?

Seems an easy way to fill the large ribs.

Bead of silicone for the small ribs and elsewhere.

I thought about that but I’m concerned about getting it in the small areas. I’m also concerned about putting too much and then I have to cut it. If the cement leveler leaks out it’s no big deal because it won’t stand out against the foundation. Just my thoughts but I could be wrong.

I would be cautious about dumping leveler in there.

If you end up creating pockets that hold moisture against the metal sheeting things are going to rust out down the line .

That’s a good point, I hadn’t thought of that. What would you suggest?

As stated, spray foam for large areas, silicone or other flexible sealant for the smaller gaps.
Once hardened, any errant drops of foam will easily scrape up.

Sounds like that’s becoming the easiest option. I really don’t want things to rust.

Is there less of a concern with foam creating an air pocket where moisture could occur?

My pole barn shop is done like that.  It was here when we bought the place pre-2000 and I haven't seen any problems with that yet.

I dunno though.  If it were me I'd probably just back the screws out, insert the strip and screw it back down.  That's what they make teenagers for.

If you want to try the spray foam, try the less-expanding foam that they make.
It might not expand so much that trimming will be necessary.

I'd back out the screws and insert the foam fillers. It will probably go more quickly than you think and it'll be done right. Anything else is a work around that you hope works but is also a gamble.

I can understand that. One of the other issues I ran into, the metal doesn’t make full contact with the foam fillers so in some places, I still see light coming through. I could probably put more screws in at the base to make it more flush

You could seal the tops of the gaps in the foam with a urethane sealant such as Sika.  They make one that doesn't flow as much as the other type they have.
