Hypertufa & Concrete Hollow Garden Sphere Project – When To Deflate The Ball
When Should I Deflate The Ball When Making
A Hypertufa Or Concrete Hollow Garden Sphere?
I received an email from Charlotte who asked:
Did I miss something in understanding the concrete and hypertufa garden spheres instructions? Doesn’t the ball have to be deflated? If so – at what point? I’m so new at this that I would probably make a really stupid mistake about deflating the balloon too soon. Thanks for your help.
My reply:
Hi Charlotte:
Thanks for writing me. No, you didn’t miss anything … I guess I assumed that folks would know that you would have to deflate the ball after your ‘tufa or concrete garden sphere is cured hard enough – better to err on the side of a few extra days rather than deflating it while you still can detect moisture–meaning the mixture hasn’t cured enough yet.
Use your best judgment to gauge the right time to deflate it. Just make sure your sphere will be able to hold together.
Please read more about concrete garden sphere tips and garden sphere how-tos which will hold true for either hypertufa or concrete.
Sorry if this threw you for a loop. And please … no question is stupid 
And I am glad you asked because now you are more knowledgeable about the issue of using the deflatable ball for your hollow garden sphere projects.
Good luck!
