Required supplies
Non-reactive nitrile gloves
Opaque container suitable for storing resin
Paint or oil filters (“fine” or 190 micron mesh size)
To filter the resin:
1. Put on a new, clean pair of nitrile gloves.
2.
Suspend the paint or oil filter (with a “fine” or 190 micron mesh size) above an opaque
container suitable for storing resin. Use a ring stand to reduce the risk of spilling resin.
3. Remove the resin tank and mixer. Place the mixer aside on a protected surface.
4. Hold the edge of the resin tank, taking care not to touch the resin tank’s underside.
5. Tilt the resin tank with the tank spout aligned directly above the filter.
6. Pour the resin through the filter, into the opaque plastic container.
