/ Most failures start here

The slab problem most contractors skip entirely

Moisture vapor pushing up through concrete is behind the majority of epoxy delaminations. We test, treat, and seal the slab before any coating decision is made.

— Why coatings fail

Invisible moisture. Visible failure.

Concrete slabs emit moisture vapor continuously. Without a proper barrier, that vapor migrates into the epoxy bond line and breaks adhesion from below — often within two years.

Most contractors skip the moisture test. They coat the slab and move on. The failure isn't the finish — it's the untreated substrate underneath it.

+ Substrate first

Test. Treat. Then coat.

Every Glosstek installation begins with a moisture vapor emission test on the slab. If readings are above threshold, we apply a two-component epoxy moisture vapor barrier rated for high-emission concrete.

Only after the barrier cures and passes a secondary check does any finish system go down. The extra day upfront is the reason the floor is still intact in year five.
