In cold storage the floor must not crack below zero, must cope with the temperature difference at the door and must stay grippy despite condensation.
Cold stresses materials
At low temperatures many coatings harden and become brittle. In cold rooms and blast freezers the floor needs a system that stays flexible and crack-free below zero.
The temperature difference at the door
When the door opens, warm and cold air meet, and the floor in this zone undergoes constant thermal change. Thermal-shock-resistant polyurethane-cement systems are often preferred here.
When to install
Coatings cure within specific temperature ranges. In a new store the floor should be coated before refrigeration is switched on; in an operating store, suitability for low-temperature application must be assessed in advance.
Condensation and grip
Moisture condensing around doors makes the floor slippery. A slip-resistant finish in these zones is important for forklift and staff safety.
Forklift traffic
Cold stores see heavy forklift traffic; an abrasion-resistant system of adequate thickness ensures a long service life.
Frequently Asked Questions
Is epoxy used in cold stores?
In low-temperature and thermal-shock areas, polyurethane-cement systems are usually more suitable.
Can an operating cold store be coated?
Low-temperature suitability must be assessed first; ideally the floor is coated before refrigeration starts.
How is slipperiness at the door prevented?
With an anti-slip finish and correct door-area detailing.
