Hypertufa Sphere Issue
I would like help making 'tufa sphere.I am using 10" ball. The mix is consistency of toothpaste but keeps slipping off the underside of the ball. I have it resting on an old flowerpot to work all the way around it. The problem is that it will only stay on the top half. Hardware cloth isn't pliable to lay smoothly on the ball, it just springs up when I try to wrap it. How do I get the mix to stick on the underside of the ball? would like to keep a small hole to plant in later. thanks!
Hi Judy, I had this issue too, but the way around it is to make the sphere in sections, gradually rolling it around and adding the mix to the top as you go. Letting it dry a bit in between (like several hours) just to let it set up will allow you to move it a quarter roll at a time. Once it's completely covered all the way around, you can give it one final coat to finish.
Other options: use chicken wire to make an armature to give you a form to follow.
Use glass light fixture globes to attach the hypertufa to.
Smear glue (Elmers white glue, or carpenters glue) onto the surface to give the hypertufa somewhere to stick.
Hope these ideas get you over the hump with your learning curve!
