Running short of epoxy resin mid-project can be both inconvenient and costly. Mixing a little extra is a simple precaution that helps ensure your job runs smoothly from start to finish.
Why Mix More Than You Calculate?
Despite careful measurements, the actual amount of resin you need may be slightly more due to absorption into surfaces, losses in mixing containers, or accidental spills. For this reason, it’s wise to mix approximately 10% more resin than your initial calculations suggest. This buffer can help you achieve a professional finish without the worry of running out at a critical moment.
Practical Mixing Advice
When preparing your resin, always round your total up by about 10% to cover any unforeseen losses. For projects such as thick table pours, consider a deep pour formula like EpoxyTable 5-Five, which is designed for bigger castings where even slight shortfalls can compromise the result. If you have leftover mixed resin, pour it into a spare mould or tray rather than discarding it—this minimises waste and can produce useful samples for future tests.
When This Matters Most
- Large or deep casting projects, such as river tables
- When working with porous materials (wood, stone) that may absorb resin
- If your project requires a flawless, seamless finish without visible breaks
