Seam Sealing Day is Upon Us!

Morning -

Great info all over this site regarding the rain gutter seam sealing job.

Question: how "high" does the seal have to be? I will be using the 3M self leveling product; some photos show it level with the side of the gutter?

Since no one answered yet, I’ll chime in.
Keep in mind I’m a newbie on the 60.

I don’t think it has to be that high as long as it’s over the seam where the top meets the gutter. As long as everything is covered should be good.

I will add, do make sure you have 2 tubes and take your time with it, but not too much time when you apply. I went too fast and had to come back cause it wasn’t covered and it doesn’t look that great in those spots.

I filled mine fairly full when I did it but that was more to keep water from sitting in there. Also, being thicker, it won't break down as quickly as a thin layer.

Well... so far mostly good. Some overspray from the 2K primer despite what I thought was adequate masking.

I ran the tube of seam sealer dry as I rounded the rear corner headed into the driver side gutter! I thought one tube would pretty much do it... I have another being delivered tomorrow. Will that pose a problem - stopping and re-starting?

Also, if I want to thicken it up in some areas… can it be applied over itself (overnight cure first)?
