hi guys- after my shellac went missing from my workshop,:RpS_cursing: had a chat with the joinery lecturer regards an alternative,
Mylands H/B water based Lacquer gloss - this was brushed onto the (dry) reverse mould, this was allowed to dry then polished off with a dry pad of scrim, this was repeated twice more - polishing after the lacquer had dried ( same as shellac) the grease was then applied, as normal - and casts were taken . The reverse mould showed no sign of damage after 8 casts.:RpS_thumbsup:
The only down side of using this product, it dries clear, and the learners found it difficult to check whether, the firstings had completely covered the reverse mould prior to positioning of the scrim, overall I was impressed with this alternative-
I will check out the price compared to shellac - don't know if it would work on damp plaster
perhaps a dye added would solve the problem, of checking
