Taking time to do this thoroughly will ensure an easy extraction of the forms. mix the concrete well until creamy and thick. for concrete flower pots, add a generous amount to the exterior larger form until almost filled to the top. then nestle the interior form into the concrete, pushing out excess cement. Step 3: fill pre made silicone molds. filling pre made molds is easy. molds come with two pieces, a soft silicone form and a harder plastic form. place the soft mold into the hard plastic form and simply fill with concrete (image 1). use a knife or skewer to stir the concrete once it is in the mold.
To make the drainage hole for the concrete planter, take a piece of a drinking straw that's about ¼” high and use hot glue to glue to the bottom of the container. use hot glue to also fill in the top open end of the straw. mix the concrete to a thick milkshake consistency and then pour the concrete into the mold. Add more concrete to top it off if necessary, and use the towel to smooth the top flat. let the planters dry for 24 hours. unmold the planter by either cutting the container or shaking it loose. let the containers cure for another week. this is necessary to make sure they are fully dry and ready to use. Follow the instructions on your bag of cement to get the right ratio. start by mixing equal parts cement mix and water. if it looks dry, add more water. add more cement mix if it looks especially wet. keep mixing until you have a thick but slightly viscous consistency, almost like brownie batter. Press the inner mold into the concrete. push the inner mold down into the center of the concrete. make sure to set the inner mold down far enough to create adequate depth for plants' roots, but also leave about an inch thickness for the bottom of the planter. brie goldman.

Remove the screws from the form and the dowel. gently peel away the sides, as shown, and tilt the planter onto its side. use your drill driver and a ¼ inch bit to loosen the drain dowel, and a hammer and chisel to punch it out. we finished our planter with a water based translucent concrete stain from quikrete. When tackling the challenge of “how to make cement planter,” abide by a ratio of 4 parts portland cement to 1 part water. mix portland cement with water for step 1. 2. form the milk carton, yogurt container, or plastic food container planter. pour the portland cement mix halfway through the carton or container.
