Mixing epoxy resin correctly is vital for any crafting or DIY project. When the balance between resin and hardener is off, the final result can be less than ideal. Here’s what can happen and how to get your ratio right every time.
Consequences of Incorrect Ratios
Using too much or too little hardener in your epoxy mix will impact curing. If the ratio is wrong, the resin might stay soft, feel tacky, or become cloudy once set. These issues aren’t just cosmetic—they affect the strength and durability of your project too. In some cases, an incorrect mix can even prevent the resin from fully curing at all.
How to Get the Right Mix
Always check your product’s recommended mixing ratio, which can vary from brand to brand. Use accurate measuring tools—digital scales (like our Precision Digital Scales) offer the best results for weighing components by grams, while graduated cups allow for volume-based mixing. Carefully combine the resin and hardener as instructed, and be sure to mix thoroughly to ensure consistency throughout.
When This Matters Most
Getting the ratio right is especially important if you’re creating jewellery, coatings, or anything requiring clarity and strength. Incorrect mixtures are more likely to cause problems for detailed or functional pieces, where a sticky or cloudy surface can ruin hours of work.
