Step 2: Painting the Rebar

I painted all my rebar with primer and rust-preventive paint using a special technique I came up with.  A  piece of 3/4" diameter PVC pipe is bent to make a paint reservoir.  The rebar is pushed in one side, passes through the paint, and is scraped of excess paint as it exits by a conical silicone rubber tip attached to the end of the pipe.  The tip is formed over the conical end of a new cartridge of silicone and is trimmed with a knife to get the appropriate size hole. 

Rust can cause the rebar to expand and damage the cement, so for best quality work it is best to paint the rebar.
