- Is it permissible to paint bars which are to be used for reinforcing concrete?
- This practice is seldom permitted, except in rare instances to prevent the corrosion of the steel in concrete structures exposed to sea air; in such circumstances, if the bond stresses are low, the steel may be painted with one or two thin coats of a red oxide of iron made up with spar varnish and China wood oil. Under most exposure conditions, 2 to 4 inches of cover with concrete of good quality will provide sufficient protection for reinforcing.
