Estonia: An industrial floor
In 2020, the industrial floor at Estonia was made with Impermax Polyurea H Flex, Colodur ECO.
01 · Project overview
What is this project?
In 2020, the industrial floor at Estonia was made with Impermax Polyurea H Flex, Colodur ECO. The climate swings from a hot afternoon to a cold night. An elastic membrane follows that movement. A rigid coat cracks.
This one is an industrial floor.
Impermax Polyurea H Flex is the spray coat on this roof, so the field and the details are one film. Colodur is the coat that stays in the sun, over the membrane that keeps the water out.
Krypton Chemical makes the resin. The crew on site applies it. On Estonia the details have to get the same film as the open field, and the cure has to finish before the building goes back to work.

02 · The challenge
What did this structure ask of the system?
Estonia: An industrial floor is a working floor. Wheels, washing water and the daily grit of a building all sit on the same film. A coating that only looks right on the day it is laid will map every crack in the slab within a season.
The concrete has to be opened, not painted over. Laitance, oil and old dust are how resin floors lose their bond, and they lose it in the traffic lines first. Joints and drains are details, not the edge of the job.
03 · The solution
Which system was trusted here?
The system trusted here is the one named for the job: Impermax Polyurea H Flex, Colodur ECO. It is chosen because it matches the substrate and the exposure, not because every building wants the same can.
A floor system is a stack. Primer for the bond, body for the thickness, seal for the face. Skipping the primer to save a day is how the floor comes back up on the tyres.
04 · Application
How is the system built?
On this floor the sequence follows the products named for the job: Impermax Polyurea H Flex, Colodur ECO. The slab is ground or blasted, the dust is lifted, and cracks are filled before the first resin. A primer is what locks the system into the pores. The body coat takes the wear. The seal is the face people walk on, and it is the layer that has to keep its colour.
Each coat has to be down at the thickness that product is designed for, including at the drains and the joints. A floor that is thick in the middle and starved at the edge will fail at the edge. Traffic waits until the seal has cured. Washing water waits longer than footsteps.
On Estonia: An industrial floor the floor is not a decorative coat. It is the surface the building works on. Preparation decides it. Oil, laitance and a closed power-floated face will take a primer for a week and then let it go. The mechanical opening of the pores is part of the system, not a favour the applicator adds if there is time.
Joints move. A resin that is rigid across a joint will crack there, and the crack fills with wash water. The joint is either honoured, with a flexible seal of the right width, or the floor design accepts a cut. Drains are turned into the floor, not left as a ring of mastic after the last coat. Colour goes in the seal coat so a repair later can be matched, and so daylight and cleaning chemicals meet a film that was chosen for that, not the structural coat underneath.
Cure is part of the programme. Foot traffic, pallet trucks and the first wash are three different dates. Opening a floor early because the building is in a hurry is how a good system gets a bad name. The data sheet of each named product sets those dates. This page does not invent a shorter one for the sake of the story.
05 · Results
What does a job like this stand behind?
Estonia: An industrial floor has one standard. The coating is still doing its job after the building is back in use, at the details as well as in the middle.
Figures for cure, thickness and strength, where they are given, come from the product data sheets. They are not a test cut out of this building.
What this asks of Estonia: An industrial floor is workmanship at the difficult line. The open field is the easy part of a resin job. Outlets, edges, penetrations and changes of plane are where thickness goes missing, and where water or wear finds the gap. The same products and the same care belong there, and the cure is allowed to finish before the building goes back into use. That is the difference between a coating that was simply applied and a system that stays in service.

Frequently asked questions
Where is this project?
Estonia: An industrial floor. Europa Este
When was the work done?
2020.
Which products were used?
Impermax Polyurea H Flex, Colodur ECO.
Why does the concrete preparation matter?
Resin sticks to a clean, open slab. It does not stick to laitance or oil. The bond fails in the wheel tracks first.
When can the floor take traffic?
Foot traffic waits until the seal has cured. Wheels and wash-down wait longer. The exact window is the one in each product’s data sheet.
