Query: Concrete at Home book

We used this book along with Cheng's other book and DVD when making our own concrete countertops. It was very helpful to us because we did a "pour in place" countertop where you build the molds right on your existing cabinets and pour the wet concrete in the molds for a seamless finish. Cheng's method for countertops focuses mainly on building molds in your backyard or garage, pouring the concrete, and then flipping the finished pieces over so you start with a smooth finish. This book has a lot of good examples of poured in place projects, so it was helpful to use this in conjunction with Cheng's countertop book.
