Stepping Stone / July 5, 2018 / Christine
When using shaped objects (such as pebbles) where you dont want them buried in the concrete but would like an even surface after placing them on top of the stone cover with a piece of wood larger than the stone and press evenly. It may take a few tries to figure out the right pressure but the professional look will add to its attractiveness. Besides pathways your garden stepping stones can be used as points for a sundial to ring a tree as wall or raised bed decorations even tabletops or to line small pools and fountains.
You can also give it a different look by using colored grout between the pieces of glass. (Putting the grout on the glass may change the perceived color of the glass in the finished product.) Flat metal punchouts are great for garden stepping stones. Wildlife garden (or other trade) tools and zodiac are all possible themes. Small colored stones could be used to make the constellations. Some garden stepping stone basics make sure you can get the finished stone out of the form by lining it with plastic wrap (rememberwrinkles may show or the plastic become trapped in the stone) or using a nonstick spray; make the stone 34 inches thick so it can stand up to traffic; let it dry for several days before you remove it from the form.
Normally there are 3 types of base material used depending on the use of the stone. Regular concrete is used most often when a stone is actually part of a pathway and decorations such as small mosaic tiles or colored stones are used for visual effect. Stepping stone concrete is used when a more intricate pattern (or 3d effect from a mold) is used. It is finer grained so there is less likely to be an air pocket in a detailed area. Finally there is plaster of paris; it is VERY fine grained and will hold the best detail of all; but lacks the strength necessary to hold up under harsh weather or traffic conditions. Garden stepping stones of this material should be ornamental only and in an area protected from weather and harsh temperatures.
