Whether an epoxy floor lasts or not is decided before the first coat is rolled onto the floor. A standard installation process is a sequence of connected steps — survey, substrate preparation, application of each coat, curing and acceptance inspection — in which each later step can only reach good quality if the earlier step was done correctly. This article presents the overall flow of the process so that project owners and contractors can share the same picture of progress and of responsibility at each stage.
This article only covers the process framework. The details of concrete substrate preparation are presented separately in the article on floor grinding, crack repair and moisture testing; detailed acceptance criteria are presented separately in the article on acceptance inspection. Separating them this way lets each article answer exactly one question, instead of repeating the same content in many places.
Step 1: Site survey
The survey is the step that gathers information before choosing a system and planning the work. Survey content includes the area and shape of the floor plan, the condition of the concrete substrate (flat or uneven, cracked or not, previously coated or not), environmental conditions (moisture, sunlight, chemicals), the expected type of traffic (pedestrians, pallet trucks, forklifts) and the time the area can be handed over for work. A thorough survey helps avoid choosing the wrong system or discovering a weak substrate only after work has started.
Step 2: Concrete substrate preparation
After the survey, the concrete substrate is prepared to create a surface clean enough, rough enough and dry enough for the coating to bond. This work usually includes floor grinding, crack repair and floor moisture testing — the technical detail of each task belongs to the dedicated article on substrate preparation, but in process terms, this is a mandatory step that cannot be shortened to meet a deadline. Skipping substrate preparation is the most common cause of early peeling, even when the material and the coating workmanship are not at fault.
Step 3: Primer application
The primer is the first coat in contact with the concrete substrate. Its job is to increase adhesion and seal pores on the substrate surface. The primer is applied after the substrate is clean and dry, at the mixing ratio of coating and hardener specified by the manufacturer. The primer must be allowed to reach the state specified in the instructions before the next coat is applied; overcoating before the coat below is ready can cause adhesion defects that are hard to repair later.
Step 4: Intermediate coat application
The intermediate coat builds thickness and flatness for the system, and also serves as the base for the topcoat. For a self-leveling system, this coat plays an important role in creating a uniform surface; for a roller-applied system, the intermediate coat may be applied in several thin passes depending on the system design. At this step, the installation team needs to control the thickness and uniformity of the coat across the whole floor, especially at joints between application batches.
Step 5: Topcoat application
The topcoat is the finishing coat that determines the colour, gloss, anti-slip performance and abrasion resistance of the floor. This is the visible coat and the coat directly exposed during use, so it has the highest requirements for cleanliness of the working environment and for application technique. Dust, insects or foreign objects falling into the topcoat before it dries all leave defects that are hard to fix without local recoating.
Step 6: Curing and waiting before use
After application is complete, the floor needs curing time for the system to fully harden before it bears loads. This time differs by product and environmental conditions, and must follow the instructions of the manufacturer — pedestrian use, light vehicles and heavy vehicles usually have different permitted start times. Putting the floor into use early is one of the easiest operational mistakes to avoid, and also one of the most common.
Step 7: Acceptance inspection and handover
Acceptance inspection is the final check before handing the floor over to the project owner for use, comparing the actual work against the agreed documents: area, system, thickness, colour and surface quality. Detailed acceptance criteria belong to the dedicated article on acceptance inspection; in process terms, the important point is that acceptance must have a written record and a clear milestone, so that warranty responsibility is counted from one agreed point in time.
Throughout the process, the four Kadier systems — RollCoat (roller-applied), LevelFlow (self-leveling), StatGuard (anti-static) and AquaBase (water-based) — all follow the same framework of steps, differing only in the materials and technical requirements of each coat according to the TDS of that system.
Note: The individual specifications of each Kadier system (thickness, consumption, chemical resistance) will be updated when the official technical data sheet (TDS) becomes available.
Conclusion
A standard process is not a list of steps to read for completeness. It is a mandatory order: a correct survey leads to the correct system choice, correct substrate preparation lets the coating bond durably, and sufficient curing time lets the floor bear loads. Shortening any step means accepting risk at the steps that follow.
If you are preparing for installation, describe your floor area and desired schedule via the contact form, or use the system selector to identify a suitable system before planning the installation in detail.
