Epoxy / PU Floor Repair
& Rectification
A running floor rarely needs replacing. Failed bays, torn joints and delaminated patches are cut out, prepared and rebuilt in the same system family as the floor around them, so the repair blends in and the area goes back to traffic on a planned shift.
What rectification covers
Rectification is the work that sits between a diagnosis and a full replacement. Delaminated bays are cut back to sound material and rebuilt, worn or damaged patches are cut square and refilled, joints that have torn or spalled are re-formed, and blistered areas are opened, dried and closed. The system used matches what is already on the floor, so the repaired area behaves like the rest of it under the same traffic and the same chemicals.
The repair, layer by layer
A repair holds because of what happens under it. The build runs from the exposed base upwards.
Topcoat & Finish
The repaired area is closed with the same topcoat family and finish as the surrounding floor, so slip character, cleanability and appearance stay consistent across the bay.
Delivered as a POLYZEN Applied System
This rectification is delivered as a POLYZEN Applied System, surveyed, specified and installed turnkey by trained applicators. The repair system, its build thickness and the finish are selected to match the existing floor, its exposure and the traffic it carries.
How the repair is specified
The repair system is chosen from what the existing floor is, what caused the failure, and what the area has to withstand afterwards. POLYZEN states the build it will lay and confirms finished values on the product technical data sheet. It does not publish fabricated figures.
Repair system, build thickness, edge treatment and finish are specified per area, exposure and the cause established at audit. Where the failure is structural rather than a surface problem, a structural engineer input is recommended. POLYZEN confirms finished values on the product technical data sheet.
Four steps on site
Mark And Cut
Failed areas are marked with your team, agreed as a scope, and cut square to sound material.
Prepare
Base and edges are ground or blasted, cleaned and dried to the profile the system needs.
Rebuild
Primer, body and finish are laid in the matching system, level with the surrounding floor.
Cure And Hand Back
The area is cured to the stated schedule and released back to traffic on an agreed shift.
Failure and treatment
| Failure | How it is rectified |
|---|---|
| Delaminated bay | Cut back to sound material, re-primed and rebuilt in system |
| Worn or damaged patch | Cut square, chamfered, refilled and finished to level |
| Torn or spalled joint | Joint arris re-formed and re-sealed to hold movement |
| Blistering | Opened, dried, cause treated, then closed in system |
| Pinholing | Surface abraded and re-coated to close the film |
| Loss of finish | Abraded and re-coated in the matching topcoat family |
| Crack in the coating | Opened, filled and bridged, or referred back to audit |
| Lifting at edges | Edge cut back and re-keyed rather than feathered |

Warranty on rectified areas
Rectified areas carried out by POLYZEN are covered by a written warranty issued with the completion documents. It covers the area repaired and the system laid. Where the underlying cause sits outside the agreed repair scope, that is stated in writing before the work begins rather than after it fails. The standard period on resin flooring systems is 12 months from handover, extendable to 24 months by written agreement, and applied waterproofing carries 5 years as standard.
