After a few years of pouring resin, you will have some experience of resin art, and you will realise that resin art revolves not only around the resin. It is also important to your tools (silicone moulds, mixing cups, heat guns and spatulas).
However, most resin artists ended up purchasing replacements too frequently due to an adhesive resin, hazy moulds or hot tools.
Here, we are going to go through the process of cleaning, restoring and making your most needed resin tools last longer, with them still working like new.
You can be a hobby crafter, or a resin business owner but your tools are directly related to the outcome.
Having proper treatment you will be able to maintain the cleanliness of your kit, extend the lifespan of tools, save money whilst achieving clearer, smoother finishes of resin.
Silicone moulds are rubbery and tough however not very strong. Cured resin, pigments, and oils may have an effect of sticking on the surface over time and minimise shine.
Pro Tip: Spray some mould release before every use to demould easier and increase the lifespan of the mould.
Heat guns and torches are necessary in terms of extracting the bubbles and creating that glassy look but they can be easily covered with resin splatter or pigment dust.
This is to prevent overheating or splattering resin, which can be prevented by considering using heat tools that can be adjusted to either an adjustable airflow or adjustable temperature, such as those in the Res-iT Tool Range.
Reusable mixing cups are simple, although you have to wash them in the right way.
Sticks and spreaders may also be reused:
Your resin tools are temperature and humidity sensitive, particularly in the UK where the climate may change.
The following are the ways to store them safely:
The choice between acetone and isopropyl alcohol (IPA) is frequently debated as a cleaning medium by resin artists.
| Solvent | Best For | Notes |
|---|---|---|
| Isopropyl Alcohol (IPA) | General cleaning, wiping tools, removing tacky residue | Safe for most plastics and silicone; minimal odour |
| Acetone | Heavy resin build-up on metal tools | Strong; use sparingly and with ventilation |
Wear gloves and keep the air flowing when taking solvents.
When your mould has faded or become cloudy, do not put it in the trash yet! You may also regain the shine with:
In case of deeply cut scratches or incurable damage, then there may be a need to replace the item but prevention will save you money in the long run.
Enhance your resin tool treatment with necessities under the Epoxy Res-iT collection:
All of them will save you wastes and make your resin performance much better, not to mention that your kit would be in excellent condition after all.
Wipe your resin instruments (cups, sticks and spreaders) with paper towel each time you pour with a little isopropyl alcohol. Allow the resin which may be left to dry completely, and then peel off. Plastic tools should not be exposed to acetone because it may lead to the tool being cloudy or broken.
Yes! Silicone moulds and flexible mixing cups can be re-used several times as long as it is clean. This can be done by letting the resin cure up and then bending it out. Mould release spray is supposed to be applied frequently to extend the life span of the mould as well as keep the surfaces shiny.
Pouring must never be done without a mould release agent or silicone spray. It suppresses the bonding of resin and promotes demoulding. The other thing you should keep in mind is that you should keep your tools clean and dry so that moisture will not make the clouds and surface defects worse.
Isopropyl alcohol (IPA) is suggested in general cleaning of resin tools in simple cleaning because its cleaning is not difficult, effective, and not dangerous to silicone. Use acetone only on metal tools or heavy build up and ensure that there is plenty of air when doing it.
Wipe tools as soon as they are used and store it in a dry dust-free area and always store silicone moulds flat so that it does not bend. Investing in good resin kits and accessories (Ex and such as Epoxy Res-iT) will result in the final result and the reduced number of replacements of tools.
It does not mean that the maintenance of your resin tools must be a hassle and a couple of minutes of cleaning after pouring can save a lot of time (and money). Being able to reuse, restore, and protect your tools will not only extend their life, but also improve your outcomes and have a smoother creative process.
Both when creating jewellery or deep geode art, the Res-iT Epoxy Resin Tool Range provides you with all that you need to make your workspace both efficient, clean and professional.
