Not heard of B7000, but for outdoor use, you always want to look at temperature. All glues are rated for such. Super quick research on B7000 shows 90-C which equates to 194-F, so about 200. That is still a very low heat threshold (though better than E-6000). Some 2 part Epoxy’s are rated at 200. As mentioned in the article, it would depend on where you live and your summer temperatures. If you have prolonged heat, I’d stick with the silicone calk products. They are intended to caulk around the exterior of doors and windows. But you could certainly experiment and discover what works best for you.

As for the mosaic: are you mounting it on the door, or replacing existing glass with your mosaic panel? I do not have enough experience to confidently advise here. I would talk to a contractor or someone in your community that sells glass or works with glass arts. I have heard about those who have used thick glass platters for a transom or green house windows- that the glass is often thicker than the glass panes for standard windows. Many entry doors have glass panels in them that aren’t bothered by ‘vibrations’, so my guess is that if the panel was secure top and bottom and sides…so it’s not swinging loose, it’s probably going to be ok.

I love making garden art, and love being able to help others by sharing knowledge and experience. When I come up against a problem or something doesn’t work out, I attempt to find out why. I also keep an ear out for problems folks experience and in the process, I’ve learned quite a bit as well!

Sounds like a great project. I love spools! But I’ve not worked with cement board before. I do know that crafters who do mosaic…even mosaic on glass or mirror surfaces or on wood use silicone. But it’s a different form of silicone. I think it’s clearer and thinner than the standard stuff in a tube. You might want to inquire at the hardware store. Perhaps checking at your local art glass store or a glass dealer? I’m thinking some type of silicone product for its excellent outdoor qualities.

Thanks for the tip, I’ll check it out. For the record, I can’t recommend a glue I haven’t personally used, but a lot of crafters desire a clear adhesive. I want to give it a try, and if all goes well, I’ll update my glue posts to include it! 🙂

I always recommend taking the flowerhead off the post and storing it over winter. It’s made to come off the post and the post can stay in the ground. And that’s what I do with my pieces as well. Just in case rocks fly from road sanders or snow blowers. If there’s a lot of snow…like this year…and a totem or birdbath or dish flower gets buried, a moose trudging across the lawn or the snow plow guy could end up damaging something beneath the surface. But I did an experiment with some ceramic dish flowers one year, leaving them out all winter. They did just fine. It’s not the cold or the snow, but just more potential for damage.

Like you, I live in Alaska too. Do you leave your tart art outside during the Winter? Or do you include them in the annual “yard pick up” each late Fall before everything freezes to the ground and gets covered up by our beautiful snow?’
