How Do You Make Sand-Cast Garden Ornaments?
Creating sand molds for cast concrete garden ornaments is a lot of fun and yields ornaments with a rustic surface that seems weathered. Bird baths, stepping stones, wall copings, bench seats, wall ornaments and shallow planters are all good candidates for sand casting. Make a simple wooden form or box that is large enough to accommodate the ornament that you’d like to make. Fill the box with mason’s sand. Wet the mason’s sand. Model the ornament that you’d like to make or find an existing element that you’d like to use as a model to create your mold. Choose a model with a bold, simple design since this method won’t pick up a lot of intricate detail. Press the model into the sand. Remove the model gently from the sand, leaving an impression in the sand. Touch up any rough spots with your fingers. Keep the sand mold moist with a spray bottle so it doesn’t crumble. Mix a batch of concrete. Experiment with the consistency. Strive for a balance of runniness – to allow the mixture to flow in
