Recycled Concrete Mosaic Planter


Recycled Concrete Mosaic Planter


A friend recently moved into a new house and inherited a lot of the former occupant’s rubbish. One of the pieces ready for throwing out was a worn slab of concrete with eight hollow sections. Instead, to become an ideal planter, it just needed tidying up—and mosaic was the perfect medium. Keep a sharp eye out for other bases for mosaics—what is deemed one person’s rubbish can definitely become another’s treasure.

Concrete Planter


  • Concrete slab
  • 100 glass brown or gold tiles
  • 200 assorted beige and pale pink ceramic tiles
  • P.V.A
  • Exterior-grade wood glue
  • Cement-based adhesive
  • Tile nippers
  • Waterproof grout


  1. Clean off any dirt from the surface of the piece and seal with 1 part P.V.A. to 3 parts water. Allow to dry.

  2. Cut the glass tiles into quarters, leaving 3 intact. Cut 70 ceramic tiles into quarters, 70 into 16ths and leave the rest whole.

  3. Using an exterior-grade wood glue, stick down glass quarters around the top edge of each opening and 3 whole glass tiles equally down the center of the planter. Fix whole and quartered ceramic tiles around the edge of the whole piece.

  4. Fill in the rest of the top with rows of ceramic 16ths. For the sides, use a cement-based adhesive as this will stop the tiles from slipping. Place a row of whole ceramic tiles around the base, followed by a row of glass quarters, and finally a row of ceramic quarters. Allow the adhesives to dry completely before using a waterproof grout in the usual way.

I really like this artful idea. You must have a TON of patience and time to be able to pull this one off. It does require a certain amount of creativity. I have an idea for a short-cut, though. What about if you bought the mosaic 12" square sheets from a big box store- where they are held together with a mesh backing- and just cut strips and pieces to fit. It would cut down on a LOT of time. Just and idea!

I've got about a dozen brick blocks in my yard, this would be a great fall project for me to do this year :) Thanks for posting it!

this is awesome...just was thinking what could I use to make this..I have some ugly Cynderblocks that might become pretty now!

What a wonderful idea! I could totally see this in our back yard.
