// mixing tips

• Measure by weight for accuracy (digital scale recommended)
• Mix slowly to avoid bubbles — stir, don't whip
• Work time: ~20-30 min for most epoxies
• Mix in a clean cup — residue affects curing
• Pour leftover resin into a thin layer to cure safely
• Never return mixed resin to original containers
