Resin flooring — including epoxy resin, polyurethane resin and self-levelling resin screed — has become increasingly common in UK commercial and residential settings. Resin floors are popular in garages, workshops, commercial kitchens, warehouses, showrooms and increasingly in domestic homes and extensions for their seamless, easy-clean finish and durability. But resin floors can sustain chip and crack damage, delamination and surface coating failure — and understanding what’s repairable helps operators and property owners make informed decisions.
Types of Resin Flooring Damage
- Impact chips and gouges — heavy objects dropped on resin flooring can chip through the surface coating to the concrete substrate beneath, leaving a rough, exposed patch in an otherwise smooth floor
- Cracks — resin floors can crack from substrate movement, particularly in new buildings where the concrete slab continues to cure and move; cracks in the substrate transmit through to the resin coating
- Delamination — where the resin coating separates from the concrete substrate, typically from moisture in the substrate at the time of application, from hydrostatic pressure below, or from coating failure; presents as bubbling, lifting or hollow-sounding areas
- Surface abrasion — heavy forklift, pallet truck and vehicle traffic in commercial settings can wear through the surface coating over time, dulling or removing the finished layer
- Chemical staining — spillages of oils, fuels, acids and chemicals in commercial environments can stain resin coating surfaces that are not chemically resistant
Resin Floor Chip and Crack Repair
Isolated chip damage and cracks in resin floors can be repaired by:
- Preparing the damaged area — removing loose material and cleaning to ensure good adhesion
- Filling the chip or crack with compatible resin filler, colour-matched to the surrounding floor
- Applying finishing coating to blend the repair into the surrounding floor finish
On plain coloured resin floors, repairs blend well. On decorative flake or quartz broadcast resin systems, matching the decorative aggregate pattern and density is more challenging — the repair is typically very good but may be detectable on close inspection.
Resin Floor Delamination Repair
Delamination repair requires identifying the cause of separation before treatment. Where moisture is the cause, addressing the moisture source is a prerequisite. Delaminated areas are typically removed back to sound substrate and the resin system is re-applied to the affected area.
When to Repair vs Recoat
Localised damage is typically best addressed by targeted repair. Where the resin floor coating has failed across a large proportion of its area — through delamination, widespread abrasion or chemical damage — recoating or overlay with a new resin system may be more cost-effective than patch repair across the whole floor.
