Replicating Huge Concrete Bird Bath Bowls: A Step-by-Step Guide
Have you seen those massive concrete bird baths that seem to be popular in every botanical garden, park, or backyard lately? Those colossal bowls add a touch of elegance and serenity to any outdoor space, providing a splash of water for birds, bees, and other pollinators to enjoy. But did you know you can replicate these stunning creations in your own backyard or garden? With some DIY know-how, patience, and elbow grease, you can create a similar statement piece for yourself.
In this article, we’ll walk you through the step-by-step process of creating a massive concrete bird bath bowl, sharing tips and tricks to help you get started.
Materials and Tools Needed
Before diving into the process, ensure you have the following materials and tools on hand:
- 94-pound polypropylene concrete mix
- 12-inch decorative aggregate (river rocks or pebbles)
- 1-quart latex-based bonding adhesive
- 1/2-quart concrete cure and seal
- Sand or sawdust for support
- A concrete trowel or edger
- A wheelbarrow or mixing bucket
- Measuring cups or a hose
- Gloves and a dust mask
Design and Preparation
Before laying the concrete, decide on the size and shape you want your bird bath to be. Measure and draw a pattern or design to ensure uniformity. Use a compass and a circular saw to create a symmetrical, free-standing mold. Cut four pieces of 2-inch thick PVC pipe to fit the dimensions of your bird bath (two for the sides, one for the bottom, and one for the inside rim). Clean and flatten the pipes for a tight seal.
Mixing and Pouring the Concrete
- In your mixing bucket or wheelbarrow, combine 10-12 inches of aggregate (river rocks or pebbles) with about 3 gallons of the 94-pound polypropylene concrete mix. You can also use a batching box to calculate the mixture.
- Gradually add water while mixing, aiming for a consistency between thick batter and thin icing. Be prepared to clean your tools often, as the mixture may be challenging to work with.
- Pour a small portion of the mixed concrete (about 4-5 inches) onto the inner rim of your PVC pipes, creating the base.
- Attach the edges of the mold to each other, creating a sandwich-like structure.
- Pour the rest of the concrete mixture around the central core, leaving about an inch of room at the top.
- Once the mixture starts to firm up, gently vibrate the mold by tapping your hands or feet to get rid of air pockets. This will prevent bubbles and ensure a more even density.
Shaping, Finishing, and Finishing Touches
- Use your concrete trowel or edger to shape the concrete bird bath, maintaining the intended design and design lines. Remove any excess concrete at the edges using a level and a measuring cup to ensure uniform height.
- Apply latex-based bonding adhesive to any areas you want to have a finish, such as the bowl’s inner surface or sides.
- Allow the concrete to dry completely before applying a waterproofing layer (1-2 ounces of concrete cure and seal per 1 gallon of water).
- Wipe off excess seal with a damp cloth, if necessary.
Assembly, Installation, and Maintenance
- Gently flip the mold to remove it from the inner rim pipe. Be prepared for concrete to crack if it didn’t dry fully.
- Sand the edges or corners of your bird bath to prevent snagging birds’ feathers.
- Install the bird bath near a power outlet for watering and maintenance convenience.
- Fill your bird bath with fresh water, periodically cleaning the surrounding area of debris.
Tips and Troubleshooting:
- Allow the concrete to dry between layers, which may extend the project time.
- Use a chisel to remove excess material if a section becomes stuck.
- Apply a UV-resistant colorant to match your original design, ensuring the bath remains vibrant in sunlight.
Conclusion:
By following this step-by-step guide and using the necessary materials, you can replicate the popular concrete bird baths found in gardens and parks. This DIY project is a beautiful way to provide a bird-friendly habitat in your outdoor space while creating a one-of-a-kind statement piece.
Really interested in making one of these! About 36" across. Any easy hacks to get a similar look?
I’d make a form out of one of those disc shaped snow sleds, something to wrap around the edge, and some chicken wire. Make sure your concrete mix is thick. Bang it on the ground or use your wife’s dildo to vibrate out the air pockets. Then maybe sand it to finish
I 3d printed a mold. used mortar. turned out great. going on 5 winters, still solid.
I only have a 16″ bed so each half had to be made in 4 parts and joined.
Flip over a trashcan lid and paint it?
But honestly, I think buying a bird bath may be the only option unless you have a stone mason around your area who takes requests
I saw a YouTube of a guy named these in his backyard
