Oiling nails, nah…never, we would just melt a block of paraffin in a gallon of gas and pour that over a keg of nails, gas flashed off and the wax made the nails drive smooth. “Gassed and waxed” was the terminology we used. Some how it got spun into “coated sinkers” today, but they call the wax “glue” hah hah Keith C.

It seems that ignorance can be both blissful and profitable. The are more than a few concrete subs cutting corners
in my area. The "time saver" which I have the the biggest problem with is the
spraying of rebar with form oil(opposed to coating the forms prior to tying bar). I am searching for data, references, field/case studies which qualify the degree of compromise.
Anyone else have this issue? Rick
*Rick:This may not be the exact info you are looking for but a previous discussion took place here that is definitely related to your question. Probably the thread just confirms what you already suspected, now, you want i data…The Portland Cement Association has a number of publications available that deal with concrete installation and related topics. They are very comprehensive. You can get a list of their publications and then order what you need. Some are pamphlets, some are books. Most are illustrated. The list is free, the pubs are not. PCA's phone # is 800-868-6733.By the way, I didn't fully understand your post - are you saying that the concrete subs intentionally coat the rebar with form release, or are you saying that the rebar gets i accidentally sprayed while the forms are getting treated? Good Luck,Matt
*I don't have any "hard data", but it goes without sayin' that there should be no oil on rebar. Those forms wouldn't pass inspection here in Western Washington.
*no Intentional oil on rebar allowed in western Oregon either, kind of like oiling nails
