DIY Indoor Planter – Mid Century Style

Are you sick of buying indoor planters that fall apart from moisture damage? DIY specialist Natasha Dickins from Little Red Industries has found the ultimate solution for a secure indoor planter that’ll last a lifetime.

“When it comes to growing greenery indoors, it’s all about the plant plus soil plus water on timber, which is an equation for potential for moisture damage,” says Natasha.

“So I’ve used a secret DIY product to make this indoor planter completely watertight,” Natasha shares.

Read on for instructions and follow along with Natasha as she creates the perfect indoor planter.

STEP BY STEP INSTRUCTIONS

DIY TOOLS & MATERIALS

  • Plant in a pot 150 x 150mm

CUTTING LIST

  • 12mm plywood cut to 250 x 150mm for the sides and 150 x 150mm for the ends of the box
  • 12mm plywood cut to 250 x 170 mm for the base of the box
  • 2 x 2.4m lengths of 35 x 8mm Porta Ribbed Edging in Tasmanian oak for the cladding, trimmed to 150mm-long pieces
  • One 1.8m length of 18 x 6mm fly bead in Tasmanian oak for the capping
  • 1.2m of 19mm dowel for the legs, cut to 300mm lengths
  • 1.2m length of 6mm dowel for the leg rails

“I’ve used a little Japanese saw for most of this project. It also helps if you can use a drop saw to cut the plywood for the box, or arrange to have it done at the hardware store.” Natasha says.

METHOD

Step 1: Make the box

Drill pilot and countersink holes into the sides, 6mm from the edge, then attach the ends using Bondcrete adhesive and 25mm timber screws, making sure the screws sit below the surface.

Step 2: Make holes for rails

On the legs, measure up 150mm from the base and use an 8mm drill bit to make the holes, then use a small drill bit to make starter holes into the top of the legs.

Tip: Clamp the legs and hold the drill upright to ensure the holes are straight through the centre.

Step 3: Attach legs to the base

On the box base, mark 20mm from the edges to countersink and secure 40mm timber screws through and into the top of each leg, then thread the dowel rails through, adjusting the legs so the rail is straight.

Tip: Dab a little Bondcrete into the holes, adjust the rails then leave them to dry.

Step 4: Complete the box

Countersink holes through the base and into the sides, apply Bondcrete along the edges then attach with 25mm screws.

Tip: Add three screws along the sides and two into the ends.

Step 5: Add the cladding

Start along one side, adding Bondcrete to each piece of cladding, positioning them to be flush with the top of the box. Pull the tape tight to hold the cladding while it dries.

Tip: Do a test fit along one side and an end, using masking tape to hold it while checking the corners overlap neatly. Remove any extra ridges from the end pieces using a Japanese hand saw.

Step 6: Attach the capping

Cut the capping to length, beginning with a long side first, measuring the inside of the mitres to match the inside corners of the box. Use a mitre box with a handsaw to make the cuts one piece at a time. Apply Bondcrete and tape the capping to hold secure as it dries.Affix the capping to the box frame using Bondcrete

Step 7: Waterproof the box

Use a brush to apply Gripset Betta Bitumen Rubber (found in Bunnings) inside the box to about 70mm from the top, leaving to dry thoroughly between coats.

“Gripset Betta Bitumen Rubber, is so lovely to work with. It goes on nice and thick, doesn’t have much odour, dries quickly, and it washes out of the brush easily! That’s my fave, all-round kind of product,” Natasha says.

Tip: Follow the instructions to apply at least two coats, brushing in different directions to ensure thick coverage.

Step 8: Smooth the surfaces

Use 180-grit abrasive paper to smooth over the cladding and capping, removing any splinters and rounding the edges and corners slightly. Smooth over the legs and over the rail join to remove any adhesive.

Step 9: Seal the timber

Use a microfibre roller with a mini tray to apply two coats of Monocel Clear Varnish over all the timber surfaces (but avoiding the bitumen), rolling into the ribbing and leaving to dry between coats.

Step 10: Add the plant

All you have to do now is drop in the potted plant, no tray required to avoid drips and spills.

“I’m inspired by mid-century design and love how the elegant Porta Timber Tasmanian oak dowel legs mirror the curves in the ribbed cladding. Finishing it with Bondall’s Monocel Clear Timber Varnish adds a richness to the woodgrain while protecting from moisture damage,” says Natasha.
