When last did you build sandcastles or just sit on your butt and draw doodles on the beach? It’s been a while for me. We don’t get to go down to the coast that often anymore. Work kinda gets in the way and we have fur babies to look after too. But this weekend, I decided enough is enough. If I can’t sit on a real beach, I can at least play with a sand mold and make something special for our home; something like this rustic concrete cross.
I hung my concrete cross outside in amongst the ivy, and she makes such a striking statement.
She would look just as good inside, or propped up on the mantle or bookcase. But since this month’s International Blogger’s Club challenge (IBC) is “Hang Her Up”, I thought I’d share how to make the hanging version. You’ll find more interesting and unique “hanging” ideas at the end of the post.
What you need
Casting concrete in a sand mold is an inexpensive and easy way to make simple concrete objects like this rustic cross. It’s as easy as child’s play and as much fun 😉 All you need is fine, damp sand, which acts as a mold for the object. I used play sand for my sand mold. You’ll also need:
- Rectangular dish that’s at least 5 cm (2″) deep
- Ice cream stick
- Cling wrap/saran wrap
- 80-grit sandpaper
- Concrete mix (cement and water)
- Wooden beads and twine (optional)
How to make a rustic concrete cross using an easy sand mold
Fill the dish with clean sand. If you don’t have a suitable dish, you can cobble something together with plywood. I used an old roasting pan. Add a little water and mix well.
Push the sand down firmly with your hands so it’s compact and fills all the nooks and crannies. Don’t make the sand too wet. Think back to those days when you built sandcastles on the beach. The sand should be just wet enough to hold its shape. If it crumples into a sandy heap, it’s too dry and needs more water. If you squeeze it in your hands and drops of water come out, it’s too wet, and you’ll need to add more sand.
Level the top of the damp sand with an ice cream stick.
Use your hands, a knife, or that ice cream stick to carve a cross shape into the wet sand.
If you’re not happy, flatten the sand out, and start again. And if you are happy and you still want to play, go for it 😉
The larger your cross, the deeper you’ll need to carve. My cross is 26cm x 18 cm, so I cut about 2cm down into the sand.
When you’re done playing, cover the “sand cross mold” with cling wrap/saran wrap to prevent the sand from sticking to the concrete.
Adding concrete to the sand mold
Pour dry concrete mix into a bucket and add a little water according to the manufacturer’s instructions. Mix well. Gently pour or scoop the mixed concrete into your sand mold. Spread the concrete being careful not to tear a hole in the plastic wrap.
Tap the bowl or dish to get rid of any large air bubbles and cover it with plastic wrap. It helps trap moisture and heat, and speeds up the curing process.
Leave the sand molded, concrete cross on a flat, level surface to harden. I used a rapid set concrete mix so it only took a few hours. Humid weather and larger projects will take longer. When the cross feels dry to the touch, remove it from the concrete sand mold and allow it to cure for a few more days.
Use 80-grit sandpaper to smooth out the little wrinkles left by the cling wrap.
Hanging the concrete cross
Drill two small holes at the top of the cross and add a string of wooden beads to hang.
Decorate the concrete cross if you’re that way inclined. I just glued a small rusty heart on with E6000.
And that’s it. You’re done.
Easy right? BTW, for something a tad more complicated but still surprisingly easy, then go have a look at these giant concrete buttons. They were made with a drip tray mold, but you can use a sand mold to make them too. Any basic shape will work.
Have you tried sand molding before? What did you make?
