Instructions
1. Remove the stakes and braces holding the forms in place. In some cases the stakes are nailed
directly to the form lumber while in others the stakes are a distance from the forms and
connected by braces. Pull the nails from the braces and stakes using a claw hammer or
wrecking bar. If duplex or two-headed nails were used, a section of the nail should be visible
for easy pulling. Some builders use standard 16d nails and do not drive them flush into the
board.
2. Pull nails connecting the form pieces at the corners using a hammer or wrecking bar. Again,
the heads of the nails should be visible. Upon completion of this step each board making up
the form is separate from all others and can be handled separately.
3. Pull the forms away from the slab. Use caution when pulling the forms loose. The concrete is
not fully cured at this time and susceptible to damage. Forms used in footings and other
below-ground applications may require some excavation before removal.
4. Clean the form lumber by scrapping any adhered concrete from the form using a putty knife
or other edged tool. The forms can be set aside for use on other projects. Often the braces and
stakes are damaged or so short they are not worth saving for reuse.
