Traditional brown shellac sealer, specially blended and tested for optimum performance (without dilution) to seal plaster casts before taking plaster moulds from them.
This Shellac Sealer can be thinned if desired with the addition of our Methylated Spirit, but it doesn't thicken well with Shellac Flakes. If you like to adjust shellac to your own requirements, try our Jenkins or Mylands Shellac Sealers.
Please note: Please ensure Shellac does not come in direct contact with silicone or fibreglass when mould making - it'll stick very well!!
