Whisky barrel planters are a perfect way to add charm and growing space to your porch or deck but they tend to be heavy and difficult to move around. Plus, without proper drainage – they’ll rot out quickly and likely only last one growing season. This project will create an improved barrel planter that is lighter in weight and has a built-in drainage system to ensure longevity.
Supplies & Tools
- Caulk Gun
- Hacksaw or Sawzall
- Safety Glasses
- Plastic Sheet (For Spills/Leaks)
- (1) Large Whiskey Barrel Planter (26" Diameter)
- (1) Bag of Sika® Post Fix
- (1) Cartridge of Sikaflex® Construction Sealant
- (1) 32 Qt. Bag of Potting Mix
- (1) 3/4" x 10' PVC Pipe (Cut to (4) 12" Lengths
Step 1: Inserting PVC Pipes
Insert the sections of the PVC piping in the pre-drilled holes in the bottom of the bucket. Using the Sikaflex® Construction Sealant, seal around the bottom of the barrel and the PVC pipes.
Step 2: Read & Roll
Be sure to follow the instructions for the Sika® Post Fix. Roll product until seal is broken and two components come together.
Step 3: Mix, Cut & Pour
Mix for 20 seconds, then cut at corner & pour the package of expanding foam into the barrel.
Step 4: Expanding Foam
Allow the Sika® Post Fix foam to expand and rise.
Step 5: Curing and cutting
After 2 hours, the foam will be filly hardened. Cut the PVC pipes flush with the foam.
Step 6: The Finishing Touch
Add soil, flowers and water. Planter is now half the weight of a soil filled planter. Foam is completely safe for plants after cure and will not absorb water. Once adhesive is fully cured, add the remaining potting mix and then add your chosen plants.
