I've used the Walkmaker mold with Quickcrete, if you still have questions after reading the threads. Good luck, Dianne

Hi Ruthann,

I made a concrete sidewalk with the mold a couple of years ago. It turned out well, and was fairly easy. My problem thou was, i did not wear safety glasses and got a small piece of the rock in my eye. Big Mistake, always wear safety glasses. That sidewalk cost me a lot of money and eye pain.

here is a link to what we did with a mold .we put weed blocker fabric down then set the mold on top.we did not remove the grass first.good luck Robin

Here is a link that might be useful: walk maker path

I have also used those concrete forms but cut mine so that I only have three large stones molds in the form....thought the cobble stone look was too busy plus was much easier to fill, just cut out the cross pieces. Might be easier to highlight the shape you want on the mold and cut away what you don't need. If doing a long walk I highly urge you to buy two forms, makes it so much faster. Tip: one bag of concrete [80 lbs.]will do one and a half forms cut like the ones I have. The good thing about them is you can stop at any point and pick back up later....been at it for 4 summers and lost count after the 385 bag of concrete.
