Issue 53 Making a Sand-Cast Birdbath

Birdbath with pedestal

Looking for a simple project with lots of potential? Try this sand-cast birdbath. It’s easy to make, works with any large leaf and it can be finished a number of ways. For a large birdbath, like the one in the photo at right, plants like rhubarb, gunnera or ‘Sum and Substance’ hosta work best. This one’s rhubarb.

You’re not limited to big leaves. This process will work with just about any type. I’ve used sycamore, oak, datura, and lantana. I use the sycamore as a ground feeder and scatter the rest through my garden.

You may have already read our story about how to make this birdbath in issue 53, but here we’ll also show you how to make a matching pedestal. There’s a modification to the birdbath in step 5, so be sure to read the instructions for both before starting.

We’ll also walk you through the whole process with our video clips.

When it comes to concrete, even though its the most expensive, I like Vinyl Patch by Quickcrete®. When it’s dry, its fine consistency preserves the details of the leaf clearly. Less expensive concretes are just as strong but they look coarser.

You can do this project on the ground, but I’d ecommend using some kind of table — it’s easier on your knees and back. I use a table made of a sheet of plywood and two sawhorses.

Who’d have guessed that for less than $25 and a few hours of work, you could have such a unique garden ornament? Are you ready to make your own? Let’s get started.

The Pedestal

Making a pedestal for your sandcast birdbath is simple, but there are a few things to do ahead of time to prepare.

First, you need a form. Most hardware stores carry cardboard tubular concrete forms that are used for deck footings. They come in different lengths and diameters. The one I got was 6 feet long with an 8-inch diameter. Since 6 feet seemed extreme for a birdbath pedestal, I cut the form in half with a hand saw. You can make the pedestal any height you want to. Just remember the taller the pedestal is, the heavier it will be when you’re done.

Now that you have your form cut to the height you want take the leftover piece and cut off a 2-inch ring. Set it aside to use in step five of the leaf project. Now you’re ready to get started.

Pour the concrete

Step one — Add the concrete. Cover the smooth side of a pre-made stepper or any smooth surface — it can even be your sidewalk or driveway — with plastic wrap and set the end of the cardboard form you cut up. This way if your earlier cut wasn’t perfectly straight, you won’t have an uneven base. Placing the form on a smooth surface will help keep the pedestal level, too.

Mix the concrete with water until it’s the consistency of pudding. The photo at left shows a good mix — not too watery, but not too stiff. Then pour the concrete into the form. This is a good time to have a friend around to hold the form while you pour. Not only does it keep the form steady but, by holding the form down firmly, the concrete won’t be able to leak out the bottom. Give it a good shake to get rid of any air pockets.

Place the stepper

Step two — Top it off. When the form is as full of concrete as you want it, center the other stepper on the top as in this photo. This will keep concrete from oozing out the bottom. Let it dry for 48 hours.

Peel off the cardboard

Step three — Finished product. When the concrete is dry, the form can be peeled off just like in the photo. When the cardboard is off, let your pedestal cure for one week.

After it has cured you can leave it as it is or decorate it with color. Either way, a coat of concrete sealer will help preserve your pedestal.
