Topic tags/keywords: bin shellac

I sprayed some 6 or so year old BIN on some MDF raised panels to seal for painting yesterday and its still sticky today so I figure the shellac has gone bad. I used this only 6 mos ago and it dried fine – oh well! My question is can I recoat with some fresh BIN or some other finish – or should I call it lost and make the panels over again?

If it has indeed gone bad, there is little you can do. Given the cost of MDF, I think I’d just start over.

False economy to try to save old finish.
Get some new stuff and quit drivin’ yourself nuts.

Thanks all. I may have dodged a bullet as they panels don’t seem sticky now. Its been pretty humid here in GA and the BIN was also tinted both of which causes delayed dry time according to the MSDS. Will check them tomorrow and if they are the least bit tacky I’ll remake the panels.

You don’t need no stinkin’ shellac. Whatever paint you use will “seal” itself.

Lesson learned. Always check the shelf life of petroleum products and review the Material Safety Data Sheets that are available from the mfg.
