Top Mistakes To Avoid When Using Epoxy Resin

Working with epoxy resin demands attention to detail. While it may seem simple at first, small steps done incorrectly may affect the final result. From the way it is mixed to how it sets, being aware of common errors can make the task easier.

These tips from recommended by an epoxy resin manufacturer apply to hobbyists and businesses.

Incorrect mixing ratio:

One of the most common mistakes when working with epoxy resin is not following the correct mixing ratio of resin to hardener. If the two components are not mixed in the proper proportions, the resin may not cure properly, leading to a sticky or soft finish. Always check the manufacturer’s guidelines for the correct mixing ratio and use accurate measuring tools to ensure consistency.

Not prepping the surface properly:

Before applying epoxy resin, the surface must be clean and free from dust, dirt, or oils. Failing to clean the surface can cause the resin to not adhere correctly, resulting in uneven coating or peeling. Always prepare the surface by cleaning it thoroughly and, if necessary, sanding it to ensure the resin bonds well.

Working in poor ventilation:

Epoxy resin produces fumes that can be harmful to your health if inhaled over a prolonged period. Working in a poorly ventilated area can increase your exposure to these fumes, leading to discomfort or health issues. Always ensure that you are working in a well-ventilated space, or use a mask designed for chemical protection to minimize inhalation risks.

Not allowing enough curing time:

Epoxy resin wants adequate time to cure fully, and rushing the curing process can lead to a soft or tacky surface. Each product may have a different curing time, so ensure to follow the manufacturer’s instructions. Avoid touching or moving the project before the resin has fully cured to prevent damage to the finish.

Using resin in high humidity or extreme temperatures:

Epoxy resin is sensitive to environmental conditions. If you apply it in an area with high humidity or extreme temperatures, it may not cure correctly, or you may end up with imperfections like bubbles or a cloudy finish. Try to work in a controlled environment, ensuring the temperature and humidity levels are suitable for curing the resin.
