How to Remove Shuttering from Concrete

Removing shuttering (or formwork) from concrete is a crucial process in construction, and it must be done correctly to avoid damaging the structure. Here’s how to do it based on the web search:

  1. Wait for the Right Time: Do not remove formwork until the concrete has developed sufficient strength to support all loads placed upon it. The timing may vary depending on the type of formwork and the specifics of the project. For instance, complete slab shuttering should typically be removed after about 5 days, while walls and columns can usually be removed after about 24-48 hours.

  2. Start at the Top: If you’re working with a sloping slab, always approach form removal from the top.

  3. Use the Right Tools: You’ll generally need a hammer and pry bar for this process5. A hammer can be used to dislodge nails that hold the forms together, and the claw of your hammer can be used to pry out any nails.

  4. Take Care with Curing: After form removal, it’s important to ensure proper curing of the concrete. This could involve water fog/spray, plastic sheets, wet burlap, or a curing compound, all applied immediately after form removal.

  5. Remove Props Last: If you’re working with slabs, these typically have props left under them which can be removed last, usually after about 3-4 days.

Keep in mind that this is a general guide. The actual process can be more complex depending on the specifics of your project and local building regulations. Always consult with a qualified engineer or construction professional to ensure safe and effective practices.
