I'm looking for advice on how to attach a 1' circular sign made of lightweight plastic (like Coroplast or Sintra) to a rough natural stone pillar. The pillar is located outdoors in a shaded spot under a roof, where temperatures range from 0°F to 80°F. My main concern is finding a way to mount the sign without drilling or permanently damaging the stone, as I might want to remove it later without leaving too many marks. I've thought about using some kind of adhesive or silicone, but I'm unsure if they would peel off easily from a porous surface. I've also heard about Sikaflex as a possible option. I do have some VHB tape that I really like, but I'm not sure it would work well on stone. Any suggestions?

I had success using clear silicone for similar projects. Just apply a small amount and then use tape to hold the sign in place until the silicone cures. For removal, a plastic razor blade works wonders. Just make sure to choose a flat area on the stone for the best results!
You might want to check out thistothat.com for advice on gluing materials together. Just keep in mind that if the stone is porous, any adhesive might stain it, so be cautious about that. Alternatively, you could consider less adhesive solutions like using clear fishing line or zip ties around the pillar—it might look a bit odd but can be effective without damaging the stone.
That sounds like a solid plan! I’ll definitely consider the silicone approach. Thanks!
