What this video covers

Mixing epoxy by volume rather than weight prevents curing failures, as resin-to-hardener ratios are calibrated for volumetric measurement.5:06 When working with small batches, apply the five-minute rule: mix only the amount of material that can be fully applied within five minutes to prevent the resin from overheating and hardening in the cup.8:47 For large-scale applications, pour the mixed resin onto the surface immediately to extend working time by spreading it into a thin layer.9:38 Avoid using U.S.-standard chopped strand matting with epoxy, as the styrene-based binder does not dissolve in epoxy, preventing the glass from conforming to radii or complex shapes.10:43 When selecting materials, prioritize 2:1 ratio epoxies for their lower viscosity, which eases fiberglass wet-out, and choose blush-free formulations to eliminate the time-consuming step of scrubbing away amine blush before secondary bonding.14:42 Adhering to these technical standards reduces rework and accelerates project timelines.
