Conklin demonstrated several different decorative effects using polyaspartic polyurea resins. He built knee walls on two sides of his concrete pad and installed a special base mold to show how decorative treatments can transition from horizontal to vertical. After diamond grinding the slab with 80-grit diamond pads to remove laitance, open pores, and flatten the concrete surface, he installed a 3-mil-thick coat of primer resin, which was almost absorbed into the surface. Thirty minutes later, he applied a 2-mil-thick “install bed” and broadcast decorative media over it. Within another hour, he vacuumed up the media that didn't stick and an 8-mil fill coat application encapsulated the media. He completed the process with a 2- to 4-mil finish coat.
