PR Drying

[rdunn12]

I did my first couple of casts with pr and the outsides of the blanks are still extremely tacky.One of the blanks was cast 2 or 3 days ago and still sticky.Feels hard as a rock,just sticky on the outside.Shop temp 65 degrees and I used 7 drops of catalyst per ounce.Is this normal or not?Ronald.Any help would be appreciated.I read the tutorials in the library and did'nt see any mention of this(I may have missed it).Thanks guys.

Ronald, this is the norm and creates no problem just turn off the tackieness on yor lathe.If you have a toaster oven you can put the blanks in the oven at 150 degress for 45 min and the tackieness will be gone.

The resin is designed to be tacky so you can pour multiple layers (to encase objects) and have them adhear to each other.
