Tutorial ~ How To Make a Hollow Concrete Sphere

By rcn48
May 3, 2012

Concrete statuary in some of the gardens I've visited has always captivated me. Unfortunately most statuary I've priced is quite expensive and with my tight budget the chances were slim that any of these creations would ever find themselves in my gardens. However, several years ago I was intrigued when I stumbled upon instructions for making "hollow concrete spheres". I was pleased to learn the cost of materials is fairly inexpensive and last year successfully completed my first sphere. I'd like to show you how easy it is and hopefully inspire you to create your own hollow concrete sphere!

It's on my radar. My "To Do" list is long like yours. But I eventually get around to things ... most of the time. Hilarious!

Do you think doing this project over the winter during cold weather would cause any problems with the execution?

Love this tutorial. Thought I had already posted, but since I didn't, I'll tell you even DH was impressed with your instructions. I think I'm going to try one when it cools off a bit here. (I notice the ad under here is for globe balls!).

I usually work outside. I have a large patio and an understanding husband! (I've already filled his garage with the stuff I inherited and can't seem to find time to get rid of).

Sandi, I'm pleased you and your DH enjoyed the article. I was surprised when I gave a presentation last spring to the Master Gardeners in the area that a lot of the men were VERY interested in making a sphere. Thumbs up

Tee, I made a few in the basement last winter, my "new" workshop. Smiling It's unheated but I used a small space heater to keep the area at least 60 degrees while I was working. Another trick one of the "crete artists" suggested was to use a heat lamp and drape a large tarp over the sphere while it was curing.

I have a garage that is mostly below grade and usually stays above 50ยบ in the winter. That is where I would work. I do have a heat lamp also so that is good to know. I really admire your sphere and the color is just lovely.
Lovey dubby
