Why Cheaper Epoxy Floors Fail Early
A Low Price Is Not the Same as a Cheap Floor
When two quotes for the same floor differ sharply, the lower one feels like the smart choice. It rarely is. A floor is a fixed amount of necessary work — slab testing, preparation, the right system, the correct film build. You cannot remove work and keep the floor; you can only remove work and defer the bill. A lower-priced epoxy floor is almost always a floor with a step taken out, and the step that comes out first is the one you cannot see.
Here is exactly what gets cut, and how each cut comes back.
The First Thing Cut: Moisture Testing
In Ghana’s persistent 81–83% relative humidity, the dominant cause of epoxy failure is slab moisture. Vapour rising through the concrete builds osmotic and hydrostatic pressure under the coating and lifts it — blistering and delamination within months. The defence is to test in-situ relative humidity to ASTM F2170 and moisture-vapour emission to ASTM F1869 before the resin goes down, and prime to the reading.
Testing costs time and a vapour-suppression primer costs money, so on a lower-priced quote they are the first to vanish. The floor looks identical on day one. It blisters by the dry season.
The Second Thing Cut: Surface Preparation
Epoxy bonds mechanically to a concrete surface profiled to an ICRI CSP standard by diamond grinding or shot-blasting, with laitance, oils and curing compounds removed. Skipping or under-doing this — a quick acid etch instead of a proper grind — leaves the coating keyed to a weak surface layer that peels away under traffic, taking the floor with it.
The Third Thing Cut: Film Build and System
The cheapest way to lower a number is to lay less material — a thinner build, or a light coating where the duty cycle called for a broadcast/quartz industrial system. It passes the handover inspection and chips out of the forklift lanes a year later. Under-specifying anti-slip aggregate has the same effect: the slip rating to EN 16165 is missing exactly where someone slips.
The Real Cost Arrives Later
A floor that fails early is the most expensive floor of all. You pay for the first installation, the downtime while it fails, the strip-out, and the correct installation you should have bought at the start. The lower-priced quote did not save money; it moved the cost forward in time and added the penalty of doing the job twice.
How to Buy Honestly
This is not an argument for the highest quote — over-specifying wastes money too. It is an argument for asking every quote the same questions: Does this include an ASTM F2170/F1869 moisture test? Is surface preparation to ICRI CSP? What film build and system, for my duty cycle? A quote that answers those clearly is one you can compare. A quote that is silent on them is lower for a reason.
