Alcohol spray for Epoxy Resin

How can alcohol spray help your epoxy resin project?

Using alcohol spray with epoxy resin can be helpful in a few ways:

  1. Removing air bubbles: 
    Alcohol can be sprayed onto the surface of the epoxy resin to help eliminate or reduce the presence of air bubbles. This is particularly useful when working on projects where a smooth, bubble-free surface is desired.
  2. Helping release your resin from moulds:
    Some tricky moulds with smaller parts can be difficult when it comes to un-moulding. Using a few sprays of alcohol spray before you pour your resin can make them easier to un-mould when your resin has cured.
  3. Cleaning Tools and Surfaces: Alcohol is a good solvent and can be used to clean tools, brushes, and surfaces that have come into contact with epoxy resin. It helps in preventing unwanted residue and ensures a clean work environment.

How to use alcohol spray

Alcohol spray for resin

Alcohol spray can be used in a few different ways when working with resin. Here’s a few tips to keep in mind.

  • Type of Alcohol: 
    Use isopropyl alcohol (rubbing alcohol) with a high percentage of alcohol (preferably 92% or higher). This ensures that the alcohol evaporates quickly and doesn’t leave behind any residue. We use this one from (Here’s a link for an equivalent product in America.

  • Spraying Technique: 
    When using the alcohol spray to reduce bubbles, mist it lightly over the resin surface. Avoid spraying too much at once, as it can potentially affect the curing process of the epoxy. One or two sprays is often enough. You can always leave your project for 10 minutes and revisit it for a second spray if needed.

    The same rule also applies if using alcohol spray on your mould before you pour.

  • Test on a Small Area: 
    Before using alcohol on your entire project, it’s a good idea to test it on a small, inconspicuous area to ensure compatibility with your specific epoxy resin.

  • Using for cleaning your moulds and pots: 
    When using alcohol spray as a cleaning agent, always remove the excess resin first. You can then spray the alcohol directly on to your moulds, pots or equipment before the resin sets and use kitchen roll or baby wipes to wipe clean. Make sure you wash with washing up liquid and thoroughly rinse before using for your next project.

  • Using to clean hands:
    It is advisable to always wear gloves when handling epoxy resin however, if you do have resin come in to contact with your skin, you can use alcohol spray to get rid of the sticky residue. Always wash with soapy water and rinse thoroughly after use.

    Safety tip: If you experience any side effects or an allergic reaction with either your resin or alcohol spray – consult a medical professional immediately.

    Always take care when using alcohol spray on surfaces such as metal and wood as it can damage surfaces if not rinsed after use. It may not be suitable for use on some surfaces. Always read the label of your chosen alcohol spray.

Top tip!

Always follow the manufacturer’s guidelines and recommendations for both the epoxy resin and the alcohol you plan to use, as different products may have different requirements.

DO NOT use alcohol spray and then apply direct heat to your mould or resin. Alcohol spray is HIGHLY FLAMMABLE and can catch fire. Do not use a heat gun, torch or flame after spraying alcohol.
