Peeling or flaking means the coating needs investigation before another coat is applied. The appearance alone does not identify the cause, and there is no universal repair that prevents every recurrence.
Describe where the failure occurs
Record lifted sheets, small flakes, soft areas, exposed concrete, tyre routes and contamination. Note the product, primer, previous finish, application date and when traffic returned. Photographs and batch details help a supplier assess the problem.
Check the substrate and preparation
Loose concrete, dust, oil, old sealers and poorly bonded paint can affect the coating system. Read concrete preparation guide. A primer does not remove contamination or make a weak slab sound; confirm the required preparation rather than adding another layer automatically.
Investigate moisture
Check for water entry, drainage problems and moisture concerns. Use the selected system’s specified assessment method and acceptance limits. A taped-plastic check is not a definitive test for rising damp or approval to coat.
Review compatibility and application
Identify the retained finish and confirm whether the new coating was approved over it. Check tools, permitted dilution, coverage, thickness, coat count and environmental limits against the actual instructions. One failure pattern can have several contributing causes.
Review curing and traffic
Compare the actual recoat and access timings with the product instructions. Touch-dry does not establish vehicle, forklift or chemical-service readiness. Use drying and curing guide to separate the stages when planning repairs.
Choose local repair or wider removal
Assess the cause, extent and soundness of the surrounding coating. Ask the system supplier whether a local repair is appropriate and how to prepare its edges. Do not assume all patch repairs will match colour or sheen, or that every failure requires complete stripping.
Recoat with an approved system
Resolve the underlying issue and follow the specified preparation, primer and finish. Compare floor paints by substrate and actual traffic. No resin family or premium label guarantees that paint cannot peel.
Keep a maintenance record
Retain the assessment, repair products and batch details. Follow approved cleaning and inspect the repaired area. If failure recurs, stop repeating the same treatment and obtain further investigation.
