Precise mixing of epoxy resin and hardener is vital for successful self-levelling pours. Getting the ratio wrong can cause irreversible issues with your finish and durability.
Why Mixing Ratios Matter
Epoxy resin cures through a precise chemical reaction between resin and hardener. Each product has a specific ratio—such as 100:55 by weight for EpoxyTable 5-Five. Deviating from this can prevent the resin from curing properly, leaving surfaces tacky, cloudy, or soft. Undermixing or overmixing the hardener not only affects strength but could also compromise clarity, making it difficult to achieve a flawless, level finish.
How to Avoid Incorrect Ratios
Always follow your resin’s instructions precisely. Use digital scales for accurate weight measurements—measuring by volume is risky since resin and hardener can have different densities. Consider using specialist tools like an Anti Bubble Mixer for thorough, gentle stirring to achieve the best blend and reduce bubbles.
- Check the manufacturer’s recommended mixing ratio for your resin type.
- Measure both resin and hardener separately and carefully.
- Stir slowly and thoroughly, scraping the sides and base of your mixing container.
When Mixing Accuracy Really Matters
Getting the ratio right is crucial in projects where surface finish, clarity, and strength are important—such as river tables, jewellery, or artwork. Products like Trasparente and EpoxyTable 5-Five are formulated for very specific thicknesses and applications, and even small ratio mistakes can mean the piece never fully cures.
