Concrete planters are made using a small container and a large container as molds. Oil the Larger Container First. To make a concrete planter, choose two containers to use as molds. Use a paintbrush to thoroughly coat the inside of the larger mold with cooking oil.
Use a paintbrush to thoroughly coat the outside of the smaller mold with cooking oil.
Fill the larger mold with concrete to about 2,5 cm from the top. Shake to eliminate ai bubbles; level the surface.
Press the Small Mold Into the Large Mold. Push the smaller mold into the center of the concrete, leaving an adequate thickness for the bottom of the planter.
Place a weight in the smaller mold and let the concrete set for 24 to 48 hours. Remove the Molds and Smooth the Concrete. Gently remove the molds. Smooth rough and sharp edges.
Feel free to experiment with shapes and sizes. Do not forget to drill drainage holes in the bottom of the pot.
Not only the shape of a pot can be the subject of creativity. Come up with a different purpose to this concrete pots. Use them as a candlestick, birdbath or arrange a pond in it.
