Work out shuttering oil quantity instantly with clear inputs, formula shown and shareable results.
Release agent is applied fresh before every pour, so consumption is formwork area divided by coverage, multiplied by the number of pours the panels will be used for. Coverage of 15-25 square metres per litre is typical for a chemical release agent on plywood or steel faces.
Consumption
Litres = formwork area / coverage per litre x number of pours
Litres = formwork area / coverage per litre x number of pours. Release agent is applied fresh before every pour, so consumption is formwork area divided by coverage, multiplied by the number of pours the panels will be used for.
