Release agent for concrete formwork

Aug 23, 2006 4 Replies

I am using wooden formwork in the making-good of a concrete slab, that had a hole made in it to access service pipes.



I would like a release agent on the formwork, which has an area of about a quarter of a square metre.



Can anyone recommend from experience something commonly available, non-hazardous, to use as a release agent for this small area? I wondered if petroleum jelly might be suitable in this application.



Regards.

polythene sheet is one of the best.

Paint the inside of the formwork with diesel.

Thank you for those suggestions. I can see that using polythene sheet will close any gaps in the formwork where two pieces of wood meet, but I shall bear in mind the other suggestions also when I do the job as soon as the weather is suitable.
