We've got a new cold store to fit out and the room is already running at about 4 degrees. My worry is the resin just sitting there tacky and never going off properly.
Cold really matters, because most resins cure by a chemical reaction that slows right down as the temperature drops, and below a product's minimum it can stall or never reach full hardness. Substrate temperature is the one that catches people out, since a slab holds the cold long after the air feels workable. For cold-store work a system rated for low temperatures, often a polyurethane-based one, is safer than pushing an ambient product past its limits. Thermal shock from wash-downs or rapid cooling is the other risk, so the floor needs building and curing for that duty from the start. Exact minimum temperatures and cure windows are product-specific, so check the datasheet or get in touch before you start.
