Introduction: Cement Planter With Stairs


I came across a "DIY cement planter mold" on Aliexpress, on little use of the search engine, the site showed a huge variety of cement planter molds to choose from. Sorry this is not an ad for them, but I thank AE for the inspiration for this project.

I decided to make a cement planter mold myself, some differences as below

  • They use silicone for mold for making this many times, I am using sun board which would like one time only
  • The overall dimensions were small 3.5" x 3.5" x 1.6", may be for smaller succulents or an ash tray, I made mine about 5.75" X 5.75" X 3.5"

I will list down each step in details, If you have queries and suggestions, please leave a comment

Step 1: What Do We Need ?

  • White Cement 1 Kg
  • Fine Sand 1 Kg
  • Sun Board (5mm or ~0.25")
  • Cutting knife
  • Pen
  • Steel measuring scale
  • Hot Gun gun
  • Super glue
  • Transparent tape
  • Water

Step 2: Outer Box

  • Cut four pieces of sun board with dimensions- 6" x 4.75"
  • Cut base of 5.75" x 5.75"
  • Tape the sides to make a square
  • We are not going to use super glue for the outer box, which makes it easier to de-mold
  • Donot attach the base yet

Step 3: Stairs

  • On the base sheet, leave 1" from one of it's edge and mark 9 dots separated by at 0.25"
  • Cut few strips of 0.75"
  • Cut these strips to size on the base sheet, we should have 9 steps
  • Stack them one over the other to make stairs
  • For the second Stairs, match the height by placing 9 full length strips( 0.75" X 5")
  • Leave about 2.75" and then start a new stair of 9 steps, each of 0.25" apart

Tip :

  • I used Super glue to stick these, instead use tiny amount of hot glue for easy de- molding
  • Because the strips were cut by Hand, there are few imperfectness. One could make the stairs even, by using some kind of filler

Step 4: Inner Box

  • The inner box is about 4" x 4" x 3"
  • Cut it's Base of 4" x 4"
  • Keeping the margins sun boarding thickness cut the sides 3.75" x 3"
  • Stick them all together using transparent tape
  • Use paper tape to fortify sides

Step 5: Mold Assembly

  • On the base we have already stuck the stairs
  • Hot glue the inner box without it's top and then hot glue the top
  • Hot glue the outer box to the base
  • Use transparent tape to seal any gaps


  • Even after my best efforts, there was a gap of 2 mm in between the stairs and the outer box. this caused issues while de-molding. I recommend first hot glue two side to stairs and then rebuild the outer box

Step 6: Casting

  • Mix 1: 1 cement and fine sand in a large container
  • Add enough water to make a semi thick paste
  • Pour the mixture into the mold
  • Because of the weight of mixture, there is a bulge on the sides, use paper tape to make it as straight a possible
  • Leave this to dry for 24 hours
  • I used about 1 Kg of each Cement and Sand

Step 7: De-molding

  • This is the most difficult part of the all
  • Slice the transparent tape, carefully and remove the sides
  • Remove the base. Since I used super glue, it did not come out well
  • Since I had gaps in between the stairs and the outer walls, i had to first sand the excess and then slowly pry the stairs
  • The inner box come out easily, just remove one side at a time and the base or it's top at the last
  • While de-molding I broke the first step, which I later super glued in place

Step 8: Final Words

  • Once the planter is properly de-molded
  • We need to sand all sides and make it uniform using sand paper
  • We need to water cure the planter for 2 to 3 days to avoid any cracks
  • Add soil / pot mixture, sow some seeds and watch the planter come to life
