They are easy to make with a few simple ingredients found at your local building supply store. Before you begin, take a good look at real boulders and rocks, carefully examining their shapes and crevices. You’ll want to replicate those natural markings.
Things You Will Need
-
In a sheltered spot away from breezes, mix together portland cement, perlite and peat moss with the hand trowel in the wheelbarrow.
-
Add water, mixing with the hand trowel, until the mixture is damp but not crumbly.
-
Let the mixture rest for 10 minutes.
-
Push the chicken wire into a rock or boulder shape. Stuff plastic grocery bags in the chicken wire holes.
-
Use the hand trowel to begin applying hypertufa mixture to the chicken wire. Completely cover the chicken wire and use the trowel to make a realistic design. Use the sea sponge to add texture.
-
Cover the completed rock or boulder with black plastic sheeting and let the hypertufa cure in a sunny spot for two to four days. Check under the plastic several times a day and mist the entire hypertufa rock or boulder with water each time. When it is completely cured and firm, apply the concrete sealer with a paintbrush.
