How to Make Carved Concrete Stepping Stones



Here in Florida, we are a couple months into Spring and that means I have a Spring project. A rather large one this year!!
I am creating a poured concrete stepping stone path in my front yard (Yes, basically I am making a mosaic with stepping stones, ha!  :).  It will be about 80 feet long when complete.
FYI: Basic How-to for stepping stones (here on my blog).

I have about half of it set, leveled and planted with dwarf mono grass plugs and Blue-eyed grass (which is actually not a grass but is in the lily family).  And I have about another quarter of the stones poured.

That bare area will get sod.

But, of course, I HAD to get a little creative!

I am using a variety of molds for these stones, only one of which is sold as a stepping stone mold (and is not pictured).

I found a plastic container with nice crisp corners and plain bottoms (intended to be used for holiday treats), and I also found a set of tiered cake tins I had picked up at a thrift store years ago.
Foil containers work too but result in rough sides plus can only be re-used a few times each.



The largest mold is the plastic saucer for a very large outdoor pot. You can see it towards the top of the photo above.






And, this ===> is what a simple poured concrete stone looks like using the pot saucer as a mold:

Blah!!




So I did a bit of research, gathered a few basic tools to carve and make marks, and got busy!

* The main carving tool I am using is the red handled X-acto with a saw blade. You can use any sort of saw you have handy, even an old kitchen steak knife.
* The old green-handles garden sheers make nice lines and gouges.
* The old dental tool makes nice lines and also smooths areas.
* That odd bit of copper pipe wrapped in a paper towel? That makes great little circles (bottom left of photo). And if pressed in and rotated well, will even pop out a bit of concrete to make a large circle depression. Nice for flower centers (second row, far left :)

I am trying to make each carved stone different.

One of these is not like the others.
Can you spot it??

TIPS:
*See my blog post on: "How to make a poured concrete stepping stone."

*Place a board or large floor tile on top of your mold before flipping. Then, after carving, move the board/tile together with the stone. Don't want to crack that soft stone while moving it!!

*Timing for carving is critical, and dependent on your own conditions: air temperature, how wet your mix was... I find it is ready to carve once the poured surface has started to loose the wet gloss and is hard to the touch. For me, this is around 8 hours at my current (warm) temperatures. There is a time window for carving, but remember, the more time after pour, the harder it will be to carve. I did a few after about 16 hours and it was rather wrist-aching!



*Lightly score your lines first, then proceed with deeper carving. Try to cut away from the areas you want to keep.

*Periodically brush off loosened concrete so you can accurately see the emerging design. I use a dust pan/brush set.

All designs are my own. If you make some stones I hope you use the opportunity to also create your own designs. Have fun!


I don't just play with concrete!!
