It is amazingly easy to create your own concrete garden benches. History Stones offers concrete molds to create bench legs as well as curved and straight bench seats. The molds are made of strong ABS plastic and can be used many times. Use ready mix concrete (less than $5 ) and water, mix and pour, allowing the concrete to set up for 24 hours before removing from molds. Similar to baking a cake, but a lot heavier! Your benches can be customized by using concrete colorants in the mix, concrete stains on top of finished concrete or use mosaics to truly personalize your creations. Creating elegant concrete garden benches is addicting and you will want to create some for your front porch and special nooks in your yard and garden
