What happens here

Ron discusses the use of forms and release agents. For thinner slabs like sidewalks (4 inches), forms often don't require a release agent as the concrete tends to break away easily once cured. However, for steps, where a smooth finish on the vertical face is desired and forms need to be stripped, a release agent is necessary. Options include specialized 'bubble gum release' or even Pam cooking spray. Diesel fuel can also be used, but it's generally not recommended due to environmental concerns.

Goal: Effectively use forms and appropriate release agents.

Tools and materials

  • Forming lumber/boards — Creating the molds for concrete structures
  • Hammer — Securing form stakes
  • Screw gun — Securing form boards with screws
  • Stakes — Supporting form boards
  • Release agent — Preventing concrete from sticking to forms
