What type of concrete should I use to make planters?
Most of the projects below use a fine grain sand as aggregate to produce a smoother finish. Quick setting concrete mix already has the perfect balance of cement and fine sand you need to make a concrete planter. Just add water!
Specialty products like Sculptcrete are formulated to work more like clay, so they can be molded and shaped to create more interesting designs. Instead of hard aggregate, it uses flexible fibers as the binding agent. This is ideal for more intricately detailed molds.
What concrete molds should I use?
Anything, really! You can reuse those empty plastic containers in the recycle bin, or cut out cardboard and laminate it with packing tape. So long as the surface is waterproof and well lubricated with cooking spray, you can get creative and make your own concrete molds!
If you want to go beyond the typical cylinder or cube, there are plenty of silicone molds to choose from! I dropped a few of these awesome concrete molds into my Amazon cart for a future project!
Use concrete dye to change the color
Concrete by itself can look cold and drab. Instead painting it (and having it flake off after a while), try dying the mix before you start pouring! The powdered dye will give you a consistent color throughout your project, both inside and out.
