Epoxy Resin - What Not to Do

Below you will find some of the bad habits that will hurt your project or yourself.

Do not use a respirator

Epoxy resins are derived from petrochemicals. It is a heavy and toxic chemistry. They do not all smell, but that does not make them harmless: effective respiratory protection is essential .

In addition, there is a real risk of developing an allergy.

Do not use safety glasses.

In continuity, your eyes are more important than your crafts!

Do not use gloves

The skin should not be put in contact with the resin, the resin cans are explicit about it.

Use powdered latex gloves

The latex does not protect the epoxy resin. And the resin does not like dust, so the powder gloves.

Use the same epoxy resin for everything

One day the resin is used to varnish, that is to say to be applied in very thin layer. The next day it serves for inclusion, ie applied in a very thick layer.

It is complicated to find such a versatile resin. To tell the truth, it certainly does not exist. Either the resin is suitable for varnishing, or it is suitable for inclusions. Rarely to both. Some varnish resins allow small inclusions, but this will not give an optimal result. However, there is no inclusion resin for varnishing. Not to my knowledge in any case.

Do not worry about storage conditions

The resin was stored in the garage, the hardener in the cellar, the mixture takes place in the kitchen, and the polymerization will be done in the bathroom.

The conditions to fuck in beauty are met.

Use one container for mixing

Dosing resin and hardener in the same container is not ideal. This technique does not guarantee a 100% homogeneous mixture in the recesses and on the walls of the container. This may cause, in places, incomplete polymerization of the mixture when poured.

Dosing the resin and hardener with the pifometer

Often we see some youtubers perform a volume dosing. At sight of the nose. Two doses of resin, a dose of hardener, approx. And presto it's folded.

Without going into the details of the polymerization of the resins, it is a chemical reaction that reacts a compound A (resin) with a compound B (hardener). Thus, a volume dosage is not precise enough to ensure that there will be the right amount of the two compounds.

Pour resin and hardener quickly

This is the best way to incorporate air bubbles! Bubbles are the enemy (with a big "E"). They ruin a beautiful surface appearance or a beautiful inclusion. You must not be in a hurry.


Tint the resin with an acrylic dye

Except if the resin supports it explicitly, otherwise it's a very bad idea. The epoxy resin likes neither water nor moisture.

Use a round stick to mix

A round stick will "sneak" between liquids, it will not mix them effectively.

Stir the stick vigorously

Stirring vigorously will have the effect of incorporating air bubbles into the mixture.

Pour the resin at the end of mixing

Like that, she does not have time to debull by herself.

Pour the resin too fast

Another good way to incorporate bubbles.

Pour the resin in multiple points

That's it, it's the latest bubble embedding technique for those who like it.

Pour the resin on a raw wood

After the direct techniques of incorporation of bubbles, here is an indirect technique.

The pores of the wood contain air. The resin will take its place, have itr will turn into small bubbles ... which, trying to escape, will become trapped in the resin.

Second "kiss cool" effect of this propagation in the pores of wood: an inclusion will give the impression of having drooled.

Observe the tasks on the slice. This is the resin that has gone through more than one centimeter of oak.

Fire with the torch

Method seen very often on Youtube. The goal is to dilate / burst the large air bubbles trapped in the resin. It works, the big bubbles burst. But small bubbles do not burst because lodged too far below the surface. On the other hand, the heat released by the blow torch has altered, heterogeneously, the polymerization of the resin. The resin will thank you by an orange peel of the most beautiful effect ^^

More dangerous, there is a risk of explosion to heat a cold hardenable resin. If in doubt, always refer to the manufacturer's safety instructions.

To debilitate with the hair dryer

If it blows too hot and / or too strong, the disadvantages of the previous point, we can add that the epoxy resin may overflow its mold.

Deburring with a heat gun

A small downside here, I am referring to the strippers that are not adjustable: they blow too hot and too strong. We then find the hair dryer defects, but tenfold.

Do not apply topcoat

She is so beautiful this resin, with its little bubulles and her pretty orange peel. Why should we still apply a finish?

Maybe to be more resistant to UVs ...
