Frequently Asked Questions

With a broad-edge tool or spatula, ideally the one supplied with your order of Eli-Chem Resin. Be sure to be thorough and scrape around the sides and base of the mixing jug to make sure there is no un-activated material. Try to not mix too fast to avoid drawing too much air into the mix.

At 15-20°C it will be tack-free in 4-6 hours, dry in 12-14 hours or up to 4 days for CER.

No, when you add more hardener you overload the system and it will result in a tacky cure, or not curing at all. Adding too little will result in the same problem. The speed of cure is determined by the amount of accelerator we formulate in the product and not by the by the amount of hardener you add. Please adhere to the recommended mix ratio on the bottles.

Lacing is created by using a heat gun to blend the edges of multiple colours together.

Canvas, Wood, Metal, Strong Card & Concrete. Plastic & Glass can be used as well, but if put under sheer loading, delamination is possible. Canvasses should be supported in the middle to avoid slumping. 

With a spirit level.

Eli-Chem manufacture a range of opaque, metallic and glow in the dark pigments. These should be used in conjunction with out range of resin. Avoid water based colours. Do not incorporate more than 10% pigment to resin ratio by weight. 

As an approximate guide, 500g of mixed resin will cover 1m² at 1mm of thickness.

  • MasterCast:- This is our most popular resin and is used for clear coating artwork and also resin art with the addition of pigments.
  • totalCAST:- Fairly similar to MasterCast, but thinner consistency and faster curing – ideal for shallow jewellery casts and some art work.
  • Clear Epoxy Rigid (CER) an unaccelerated water clear resin:– Used for deep casts as it does not generate heat whilst drying. Takes 3-4 days to cure.
  • General Purpose (CEL):- A low viscosity resin which can be used to coat art work, but also ideal for applications on floors or work surfaces.
  • UltraCast XT:- An epoxy coating/casting resin with excellent surface heat resistance up to 95°C, suitable for tabletops, bar counters and kitchen worktops.
  • Glass Clear Polyester:-Glass Clear Polyester Casting Resin is an optically clear, two-part polyester resin used to encapsulate and embed a wide variety of items.
  • Eli-Dome Polyurethane Doming Resin:- A water-white resin that is free-flowing and self-levelling offering excellent surface penetration and provides a 3D lens on the surface of your component.

Layering multiple layers of coloured resin into one container, give a gentle ¼ stir then pour into the centre of a level surface and allow the resin to flow. resi-BLAST can also be added to a couple of the layers.

A general purpose contact adhesive, such as Gripfil can be used.

That depends which of our resins you’re using. MasterCast 1-2-1 & totalCAST both have an exothermic reaction during the curing process meaning you need to limit how think they are poured to, to avoid too much heat.

If you need to cast at depth, our Clear Epoxy Rigid can be poured to any depth up to 12L per pour.

Although our resins are all user-friendly and non-toxic please bear in mind they are still industrial chemicals, therefore we advise the observation of good industrial hygiene.

Make sure the room is well ventilated when mixing and applying resin, we recommend using latex, nitrile or other gloves and keeping the skin covered.


It is either too cold for the chemical reaction to take place, the mixing ratio used is incorrect or the mixing itself was not thoroughly enough and un-cross linked material is present.

With difficulty, the best way in this scenario is to mop up what you can when wet, then leave to dry and try to break off or cut out.

The application of heat from a low speed heat gun will draw air out of the resin when it is still wet.

There is a difference in viscosity between the resin and the hardener meaning the ratio end up with one component being slightly heavier than the other. However there is a margin for error built in, meaning using 1:1 by either volume or weight gets perfect results.
