What to fill the gap with?

[Brad_bb]

After renovating/closing in what used to be a cow stall area of my pole barn... I have sheet metal trim at the base of the wall. The floor is Rustoleum floor epoxy. I need to fill the gap between the trim and floor to prevent water from going under, especially in the area shown in the first photo what it is sloped towards the wall(used to be to the open outside).
   What should I use to fill/caulk the gap? I tend to stay away from Silicone based products due to the my cars and painting in my shop. Thanks.

Maybe some sort of epoxy.

Brad,

If you don't like/want to use silicone, then maybe you could try an elastomeric like this one:  http://www.dynasolv.com/Our-Products/elastomeric-caulk.html.   It is suppose to be real good for dissimilar materials.

I have had good luck with Black Jack wet/dry roofing cement patching holes and filling gaps on roofs.  You can get it at Lowes.

I have used "Stretch" caulking.

I would try to find a good roofing caulking and go with that. Should not be too hard to find, here we have a brand name  " flextra"  wich would be ideal for that.

Pro-seal is a good water proof sealant for metal roofing and siding. Although its 8.00 a tube. Sika-flex is a cheaper tube and grey is standard color. Both have silicone in them though.

Silicone, once it gets on paint, is extremely difficult to remove all of it.  Then when you go to paint, the paint beads off like water on oil.  Autobody paint shops do not let anything with silicone in their shops to avoid contamination.  Just when you think you got it all, go to paint, and blam, all messed up.  Many will not use silicone based tire shine.  I also restore my classic cars and nothing silicone ever goes in my shop.

Silicone is like very small micro ball bearings.  Because they are so small, makes it very difficult to remove all.  Silicone actually has a distinct feel if rubbed between your thumb and forefinger.

OK, I didn't know if it was fumes or what.

Urethane Windshield Adhesive works well, I use it on the rv roof where vents and such penetrate the membrane. Get mine from an auto glass installer friend.....

As long as you don't make a huge mess, applying a bead of silicone caulk will do the trick, and once it is dry there should be no problems with it spreading anywhere. Just don't go wiping your hands on everything until you wash your hands ;)
