| FORM REMOVAL
Forms should be built to allow easy removal without danger to the concrete.
Before concrete is placed, forms are treated with oil or other coating
material to prevent the concrete from sticking. The oil should penetrate
the wood to prevent water absorption.
A light bodied petroleum oil will do. On plywood, shellac is more effective
than oil. If forms are to be reused, painting helps preserve the wood.
If form oil is not available, wetting with water may be substituted in
an emergency to prevent sticking. Wood wedges should be used to wedge
forms against concrete, rather than a pinchbar or other metal tool. To
avoid breaking the edges of concrete, forms should not be jerked off after
wedging has been started at one end. Forms to be reused should be cleaned
and oiled immediately. Nails should be removed as forms are stripped.
CAUTION
--Permit only workmen doing the
stripping in the immediate area.
--Do not remove forms until the
concrete has set.
--Pile stripped forms immediately to
avoid congestion, exposed nails, and
other hazards.
