Fiber-Reinforced Concrete planter

A 5-gallon bucket and a few pounds of CHENG’s D-FRC concrete mix are used to create a brilliantly simple planter. The fiber reinforced concrete mix is pressed into a bucket at 1/2″ – 3/4″ thickness and allowed to cure overnight before demolding.

What You’ll Need
  • Paddle Mixer
  • 17- or 25-Gallon Mixing Bucket
  • Alpha VSP-120 Concrete Polisher
  • CHENG D-FRC Casting Blend
  • CHENG D-FRC Activator
  • CHENG SmartColor Pigment

Step 1 – Hand-Pack

  • Begin by placing handfuls of fiber-reinforced concrete at the bottom of the bucket.
  • A drain hole can be created using a cork or a rubber knockout as shown in this example.
  • Pack handfuls of material up the side walls, about 1/4″ in thickness.
  • Carefully build up the side walls. Adding too much concrete at one time will cause the walls to slump down.
  • When the concrete has reached the desired thickness and height, smooth the inside with your hands.

Step 2 – Demold

  • After the concrete has cured, it can be removed from the bucket.
  • Pry the walls of the bucket away from the concrete to break the seal. Turn the bucket over and the weight of the piece should let it drop out easily.

Step 3 – Grind and Polish

  • The rim of the planter can be smoothed using diamond hand sanding pads or an orbital polisher.
  • Draw a line evenly around the rim and use it as a guide to polish down to.

Step 4 – Finished Planter

  • The finished planter can be used indoors or outdoors.
