What happens here

Timing is crucial for removing formwork. If you pull the forms too early, the still-wet concrete edge will come away with the forms, damaging the clean edge you were trying to create. Wait until the concrete has set enough to hold its shape but is still workable enough to remove the forms without excessive force. Once removed, you can easily finish the edge using an edger if needed.

Goal: Remove formwork without damaging the freshly set concrete edges.

Tools and materials

What they say

Hide

opposite direction of the screed, if we wait till the right time to mag, around a quarter inch depression, the slab stays flat and is much easier to work on. If we pull the forms too early, this edge will come with it. If we pull these forms at the right time and the right way, this edge can be easily finished. If you broom too early, you'll get a bad finish. If we broom finish at the right time, this will turn out much better.
