I gather you asked about a form release. Petroleum naptha is a great release
and won't attack the cement. Paste floor wax works very well especially for a
one time use and is likely cheaper than the naptha. The brand name of the
petroleum naptha is Magic Coat. The wax is rubbed on with an old rag and the
Magic Coat can be sprayed on up to 24 hrs in advance of the pour. I spent 6+
years in the precast concrete buiz.

Get a gallon of diesel fuel ($2.50) which is a very light oil really,
and pour it into a garden tank sprayer. Spray the wood until it is
nice and wet. The concrete will not stick and the wood has a preservative
treatment !
