Wool has so many amazing qualities that it deserves the beauty of Eco Printing. I'm…
I like competition and especially winning! This was my entry to the Quikcrete-1-Bag-Wonder Contest. ‘Take a bag of concrete and create something unique. Well, I’d say I should have won, but I guess ‘beer’ won out. I’ll get over it eventually as I can now enjoy my unique creation in my garden (which incidentally won a Trillium Garden award). You too can join the fun and make your own DIY Gigantic Concrete Leaf Orb.
The Concrete Mix:
As you know I love to use Rapidset Cementall but since it was a Quikcrete contest I needed to use their product; Fastset All-crete. (may be under a different name in the US) I know it can get confusing when choosing a mix so I’ve made a post here to help you.
Once you have used fast setting mixes it’s hard to go back… I know.
The Mold Material:
It’s old news that many use Rhubarb as a way to cast nice detailed leaves. I don’t have enough production of Rhubarb so I was looking for an alternative and came across one at the grocery store! ‘Artist brain’ is always looking at things in a different way. I’m the only ‘crazy’ looking at food for it’s great textural value.
Savoy Cabbage is perfect! It has such great pronounced texture and it is quite sturdy so it lasts well.
Gather your supplies
- large inflatable form (24″ beach ball worked well)
- bucket or bowl to stabilize the ball
- Gloves and concrete dust rated mask
- FastSet All-Crete
- Fibreglass drywall Mesh
- Mixing Vessel, spoon & water
- Savoy Cabbage leaves
Blow up the ball and set it in an appropriate container that will keep it from rolling or toppling.
Mix up only small batches as this will set quite quickly. I use a container that is about 500ml (yoghurt). If you let it sit for about 30 seconds it stiffens nicely to make applying easier. Aim for a consistency that is quite pliable and plastic-like. You will get the hang of the consistency after a couple mixes, don’t worry.
To ensure strength it is key to have good over lap of the shapes and reinforcement material. The first layer is thin leaf shapes that join allowing the mesh strips to be layered over.
Make sure that you have good connection to the shapes. I work form the top middle outward.
Since the Cabbage leaves are quite large they will probably need trimming to shapes that match roughy the size you intend to use on the orb. You can use larger if you like as they tend to have some curvature as well. If they are too stiff, you could leave them to wilt a bit in the sun or zap in the microwave for a bit.
You are using the underside where the veins are. Put some mix on the shape replicating the size that you have on the orbs.
Quickly but gently ‘slap’ the leaf onto the one on the ball. Wriggle it to make good contact with the concrete. You can peek under to see how the shapes are joining and adjust if needed.
You can be fussy or more ‘rustic’ if you like The overall charm is the leaf textures anyways!
Around & around:
I work outward from the middle of the top and slightly rotate the ball to work outwards when it is hard enough. Keep the idea of gravity in mind. Do leave the valve opening accessible as well. The mesh also helps any shapes from sliding.
Since this mix sets so quickly I found that the leaves could easily be pulled off in a short time (will depend on your conditions like temperature etc) I even discovered that the cabbage leaves are so hardy that they will last through repeated use!
Wonderful Texture! If you have any concern that there are some weak spots where overlap did not occur that much you can add a leaf on top extra assurance. If it is really hot misting with water will help slow the curing a bit.
Do let the final shape cure well. I’d wait 24 hours to be sure. Open the valve and start to deflate the ball until it is small enough to pull out.
Any excess mesh can be cut or singed off with a mini torch as I did with these orbs.
The wonderful thing about these orbs is that they are light enough to carry! That one is about 25″ across and I can hold it no problem. It has such interesting shapes I’m hoping to install lights as well for great night lighting effects.
As a garden designer I believe that the ornaments should look natural in the garden not ‘kitschy’. That’s why the leaves work so great. They also echo the stepping stones that I have a ‘million’ of!
I am so delighted with this orb, I think it’s my favourite of all the orbs (but who knows) And I keep getting bigger! Bring on the exercise ball…
Garden delight… and wait til the snow in winter. Thanks for joining me in my garden and my concrete obsession! Go beautify your space!
