Introduction: How to Make a Concrete Base for Many Applications
One of the most versatile concrete objects we've ever made is this base in which we embedded a metal pipe cap in the center. With the cap in the center, a metal pipe can be screwed into it or PVC can be used with the appropriate adapters.
We originally used it to hold a DIY A-frame Christmas tree and then we reimagined the base in use as the support for an outdoor garden flag stand.
We then used it for two night stands and a metal pipe fireworks lamp!
Others have suggested using it for holding a photo backdrop, to hold 8 foot poles on which to string lights for an outdoor wedding, use it for an outdoor patio table or as a base for a bird feeder.
Many uses for the same base!

Step 2: Secure the Metal Cap in Place
To get the look we wanted, we selected a plastic bowl that is much narrower at the bottom than at the top. We've used different ones over the years. Any plastic bowl seems to work. The base with the pattern is actually a bowl from a local grocery store deli. (The deli bowl was very flimsy so we set it inside a more sturdy bowl.)
Clean the top of the metal pipe cap before hot glueing in place. Be sure the bowl bottom is clean as well. If there is any grease or dirt the cap may not glue to the bottom.
You are glueing the open side of the metal pipe cap down into the center of the bowl. Hot glue and press and hold it in place while it dries
Step 3: Mix Concrete or Cement
Mix up whatever concrete or cement you are using in a separate container. Be sure to read the instructions on the packaging. Wear appropriate safety gear such as a mask, eye protection, and gloves.
Our preferred cement is RapidSet as it sets up in about an hour and dries to a nice white smooth finish.
Gently pour the cement into the prepared bowl. Pour slowly as you don't want to accidentally knock the cap out of place.
Smooth the top and gently tap the sides of the bowl to bring any trapped air bubbles to the surface.
Step 4: Clean Up the Edges and Finish
Once the concrete or cement has cured, remove it from the mold. This is the one we made with the deli bowl. Once it was throughly cured, it did not remain shiny.
If there are any rough edges, use a sander to clean up the problem areas.
The base can be left natural, sealed with polyurethane or it can be stained. This one was stained with Rust-Oleum Varathane wood stain in weathered grey.
Lastly, add self-adhesive felt to the bottom to protect floors from the hard concrete.
Step 5: Uses for the Base: Outdoor Flag Stand
With the base dry and upright, any one inch diameter metal pipe can be screwed in. For the garden flag stand, which you see above, we used PVC fittings. Please refer to that video to see it come together.
Step 6: Uses for the Base: A-frame Christmas Tree
To use the base for a DIY A-frame Christmas tree a small piece of pipe was put through a hole in the tree base and all secured with a metal pipe cap.
Step 7: Uses for the Base: End Tables and Lamp
We made a couple of nightstands with bases. These are stained brown.
And lastly, we used the base when we made a floor lamp with built in table.
As you can see, the basic base lends itself to a variety of uses. How would you use it?
