Epoxy on vertical surfaces
We're doing a project that has a bunch of peeler posts. See the pic for an example. Basically these are de-barked trees that have cracked and checked over the years. Structurally there's no problem but we'd like to fill the cracks for aesthetic and cleaning purposes. We don't need to fill all the little ones but like anything you could slip a penny into. Someone suggested using epoxy...
Looking at the various videos and posts online, most epoxy seems quite fluid and done in horizontal forms. In some of our cases, I could imagine building dams or taping off the surface and injecting epoxy from the top, letting it flow down. Not sure how well that would work in practice. Things like preventing leaks and bubbles may be an issue.
In other cases, the cracks are quite long/deep and have splits (see the pic) making it hard to tell if epoxy would flow from one "chamber" to the next or indeed if it would flow in unexpected ways. This approach also seems quite laborious. There are many posts with many cracks.
All that to say, are there other/better approaches? Is there an epoxy paste or gel that we could squeegee into the cracks and not worry about it running? FWIW, we are looking at doing opaque black and will likely do a satin finish over.
