    This product was easy to work with with no fuss or must of mixing on the side just pour it in the hole and add water. Sets up quickly so you can continue to work on your project without losing a day. I would recommend this to anyone looking to put in post holes.

    Quickset concrete mix
    The yard has a bit of an incline, so I had to stack a row to get the proper level height. The concrete needs to be sifted to get pebbles,etc out. The key is to lightly mist the mix to begin the hardening process.. definitely would use again

      I used this to make stepping stones and compared it to the vinyl patch mix : both will work. The Quickcrete provides a more natural, pebbly background . If you work fast, you can insert shells and mosaic pieces, but be ready with your materials because it hardens quickly! It's just a preference, but if you want a more rugged look, this is your medium and more slip proof as well. Just mix up what you are immediately going to use, and have a little extra mold ready in case you have extra left over. Have fun !
