Each casting uses 80 lb of concrete mix. Just fill each cavity of the mold, smooth the surface and, after 1 minute, remove the mold to start the next casting. Each time the mold is moved, it's rotated to give a matching connection with the section just cast.
Comes with full instructions, including how to make curves, corners, and different surface textures.
Made of strong recycled plastic. A very economical way to create an attractive walkway or patio.
Made in USA.
