Very nice rotting log effect! Excited to see where you go with this.
Wow great job on the tree roots, the first pic of them covered in spray foam looks like a rib cage for a horror film production!
You have coated the structure with something, tile glue perhaps?
I'd love to make a bit of horror scenes.
Indeed, tile adhesive. And then some grout.
Have you just applied the spray foam & then shaped it with a craft knife or sand paper?
Got that right, my friend. Just a knife to make the base for the tile adhesive.
How have you applied & shaped the final coating, with a small trowel & paint brush perhaps?
Brush and trowels is right again. No magic!
If it is tile glue, is the glue epoxy based & inert when cured?
Whatever way, you have done a great job...something I like doing too although your techniques & skills are advanced on mine!
No, not epoxy based. Just cement based with some of the modernish glues they stuff the adhesive with.
And then some grout. I add a bit of copolymer to it.
Inert? Not totally. curing period is like a month and there's some leeching of lime after that.
I see no problems there...
Thanks for your words! I don't know where this thing is going to, exactly, but trying out a couple of new materials and procedures keeps me interested...
I think I'm going to be getting on with it nicely, since the weather forecast for the foreseeable future up here is:
Thanks for your comment.
