A coating’s fate is written before installation: surface, ambient conditions and the hidden moisture within the concrete
When a floor coating fails, the material is the first to be blamed. Yet the source of the problem is usually hidden before the installation: in the surface, in the ambient conditions and in the unseen moisture within the concrete.
When we go out to examine a damaged coating in the field, the first sentence we hear from the operator is usually the same: “the material did not hold.” The coating has blistered in places, come away at the edges or worn out far earlier than expected, and the eye naturally blames what it sees. Yet one of the clearest lessons of our thirty-plus years in the field is this: a coating’s fate is decided before the coating itself. Three factors decide it, and none of the three is visible on handover day: the preparation of the surface, the ambient conditions on the day of installation and, the most insidious of all, the hidden moisture within the concrete.
The surface: the only ground the coating can hold on to
A coating lives as long as the bond it can form with its surface. And the quality of that bond is established before the day of installation. The substrate’s load-bearing capacity, its cleanliness, its texture and the traces left by its past define the conditions the coating will live under. The residue of an old coating, an unnoticed oil stain or an inadequately prepared texture undermines even the finest system. That is why, in our applications, we treat surface preparation not as a preliminary step but as the work itself; the life of the system begins here.
The ambient conditions: the invisible third party of the installation
Three parties sit at the table of every installation: the surface, the system and the ambient conditions. The first two get discussed; the third is usually forgotten. Yet the temperature on the day of installation, the humidity in the air and the momentary condition of the surface are preconditions for the system to cure properly. An application carried out on a day when conditions are not right gains one day on the schedule and can take years off the life of the floor. Deciding to wait on site can sometimes look like a loss to the client; in our eyes, a crew that waits is a crew that knows its job.
Hidden moisture: the patient enemy inside the concrete
The third factor is the most deceptive of the three. Concrete can hold moisture inside even when its surface looks dry. This moisture cannot be seen, cannot be felt by hand and gives no sign on the day of installation. It gives its sign months later: it accumulates beneath the coating, pushes the system away from the surface and comes back as blistering and delamination. The operator blames the material; yet the culprit is a question nobody asked on installation day: how much moisture is inside this concrete?
That is why we have one non-negotiable rule: we do not install without measuring. The moisture of the concrete, the condition of the surface and the ambient conditions are measured before installation using internationally recognized methods, and recorded. If the measurement results are not suitable, the installation waits; because moisture is an enemy that knows how to wait, and the only way to beat it is to be more patient than it is.
Conclusion
When evaluating your flooring investment, look at the process in the bid documents, not just the system: how will the surface be prepared, how will the ambient conditions be managed, and will the moisture of the concrete be measured? A bid without clear answers to these three questions is selling you not a coating but an uncertainty. Send us your questions; let us write that fate, the one written before installation, correctly together.
