Focus On Resin

We ask four resin artists for their top tips!

Read the instructions carefully and weigh or pour volumes of resin
and catalyst (hardener) very accurately. Different brands have
different recommended proportions so do be sure you've got the
right ones!
Mix gently, but thoroughly. Most resin doesn't set because it's
been poorly mixed. You don't want to beat it and trap air; just
stir vigorously for the whole of the recommended time, usually 4-5
minutes.
To clear air bubbles, place a lamp above the project, as the bulb
gets warm it will make the resin thinner and draw the air bubbles
to the surface where they can be popped with a pin.
Place a jug or bowl over your pieces while curing to avoid
dust/pet hair drifting and settling in the mix!

The following tips are for Apoxie Sculpt, which is a
self-hardening two-part resin clay. Malleable for 2-3 hours after
mixing, it requires no baking and sets rock-hard after 24 hours.
The clay adheres to other surfaces and itself.
Items that wouldn't withstand baking, for example acrylic stones,
beads or delicate materials can be set or embedded in resin
clay.
If the resin clay becomes too sticky after mixing, then either
place in the fridge for a short while or put some Vaseline on your
fingers.
Smooth the resin clay with
a little cold water - this also helps to prevent it sticking to
your fingers or tools.
Mix pre-coloured resin clay to make new shades or add a drop of
oil or acrylic paint, powder pigment or mica to natural coloured
clay.

When using casting resin, it is much easier and more accurate to
get the correct mixing ratio using mini jeweller's scales.
If you are having trouble getting something out of a mould (bangle
moulds can be particularly tricky), then put it in the freezer for
a bit and it will pop out ten times easier.
Don't be surprised that in the winter resin can take slightly
longer to cure. When it gets cold the resin can take an extra day
or so to become fully hard.
Leave a mixing cup and stick next to a project. Use this to test
the state of the resin, which prevents anybody from sticking their
finger in and ruining the project!

Experiment with new ways of colouring resin. Epoxy resin will not
work with anything that has water in it because it makes resin
cloudy. Use dry powders and other dry materials.
Line up several projects to put resin into - then you will have
less wasted material. If you have made too much, put it on an
acrylic sheet; when it is set you can lift it off and use it in
collages.
To find out how much resin you will need, weigh a piece without
resin in and one with resin in - the difference will be the weight
of the resin and hardener that you will need in future. It is worth
keeping a record of weights.
Follow health and safety instructions that apply to the resin that
you are using. Always work in a well-ventilated space. Your
workroom needs to be at least 18°C for the resin reaction to work
properly.
