Left: After the ties had hardened overnight they can be removed from the forms.
We recommend removal within 2 days. The reason is a certain amount of cement cream or slurry is going to excape under the insert and solidify around the peg or pins. After a couple of days prying up the ties off the pegs might damage the plastic mold since the cement will no longer be "green".
Using a pointed shovel pry the molds off the gang forms equally from side to side 1/4" inch at a time until each form is up and off the pegs.
