Cooler & Freezer Floors Installed Without Shutting Down
Most floor systems need a warm room to cure, which means emptying the cooler, shutting down refrigeration and losing days of capacity. PumaCRETE urethane concrete flooring cures down to 35°F, so it goes into operating coolers. For active freezers, fast-curing MMA repair options fix damaged areas without a thaw.

What cold storage does to a floor
Rooms that can’t warm up
Epoxy needs temperatures well above 60°F to cure. Warming a cooler means moving product and shutting off refrigeration. PumaCRETE cures at 35°F.
Condensation and frost
Doors open and close all day, so warm air condenses on cold floors. The system is non-porous and keeps its slip-resistant texture when wet.
Forklift and pallet traffic
Cold storage aisles see constant forklift traffic, often with hard wheels. The 9,500 psi system resists wheel wear and impact.
Thermal cycling at doors
Floors at dock doors and room transitions swing between ambient and cold many times a day. Thermal expansion matched to concrete prevents cracking.
Blast freezer extremes
Blast freezers and spiral freezers run far below zero. The system is rated for service down to -40°F.
Joints and damaged slabs
Spalled joints and cracks trap water that freezes and expands. Joints are repaired and the topping seals them over.
Recommended system by zone
One urethane concrete system, configured for the room you’re standing in. Thickness, texture and cove are set zone by zone. Add 1/8 in for integral cove.
| Zone | Recommended system | Key exposures |
|---|---|---|
| Coolers (33–40°F) | 401-HF, 1/4 in (cold cure) | Condensation, pallet and forklift traffic |
| Freezers and blast freezers | 401-HF, 1/4 in where rooms can be raised to 35°F+; MMA repair option for active freezers | Sub-zero temperatures, frost, forklifts |
| Dock doors and transitions | 401-HF, 3/8 in | Thermal cycling, impact, water tracking |
| Cold staging and order picking | 401-HF, 1/4 in | Pallet jacks, foot traffic, condensation |
| Refrigerated processing rooms | 401-HF, 1/4 in + cove, slip-grade | Washdown, cold, product spills |
Keeping refrigeration running
Install at room temperature
In coolers, PumaCRETE goes down without warming the room. The optimal install range is 40–50°F.
Freezer options
Freezers are either raised to 35°F or above for a short period, or repaired in place with fast-curing MMA. We’ll recommend the right option for each room.
Section by section
Racks and aisles are done in sections, with product moved within the room rather than out of it.

Frequently Asked Questions
Cooler & Freezer Floors FAQ's
Yes. PumaCRETE 401-HF cures at temperatures down to 35°F. The optimal install range is 40–50°F, which matches most coolers.
The standard system needs at least 35°F to cure, so freezers are either raised briefly or repaired with a fast-curing MMA system. The finished floor is rated for service down to -40°F.
Foot traffic at 6 hours, light wheeled traffic at 12 hours, and full forklift service about 24 hours after the final coat at 70°F. Cure is slower at cooler temperatures; we schedule around it.
No floor topping fixes frost heave, which comes from frozen ground under the slab. We assess the slab during the site visit and tell you if structural work is needed first.
