I bought my mold from : http://www.gardenponds.com/molds6.htm......I used what they recommender, 8 parts Denatured alcohol & 1 part castor Oil for the mold release agent. .. I have used vegetable spray in the past and it worked fine....Used the recommended Sancrete Sand Mix. Brands may change depending upon where you live. Traced the outline of a brick onto a piece of shirt cardboard..I did take a little off the width and the middle brick I made shorter to look better.. Then traced onto the concrete...I left a 1/2" space for the "grout" which is the unpainted concrete..I bought 2 different color paints from Lowe's Concrete paint, Brick Facade and Poppy Field... you may want to match your brick color.. Painted the darker color on bricks first the came over with a little of the lighter color on a rag..kind of like a light wash...I think they turned out pretty and are easy to do!
