Product Review

Product reviewed

An epoxy resin floor system (including a colored epoxy layer with decorative “petals”/flakes, finished with a matte varnish). The main issue described is that the epoxy resin layer did not cure properly.

Key features mentioned

  • Colored epoxy resin for the visible effect, including decorative flakes/petals
  • Matte varnish as the final floor finish
  • Curing requirement: needs at least ~10°C during application and drying (the speaker cites this minimum)
  • Mixing ratio: 4:1 resin to hardener, but the speaker notes this depends on the mixing method and that the correct ratio must follow the technical guidance

Problems / cons (main negative points)

  • Improper curing / not hardening in multiple spots:
    • Marks/deformation and areas where the resin “has not dried and will not dry”
    • Subtle cracks/wrinkling when viewed at an angle, suggesting incomplete hardening
  • Heating attempt didn’t solve it:
    • Heat gun/heater trials reportedly did not make the resin cure
  • Overall rework burden:
    • Material waste and time loss are explicitly mentioned
    • Weather delays caused work to stop longer than planned

Root causes identified (speaker’s perspective)

  1. Temperature too low during curing

    • Application was around ~10°C, but nights and subsequent days fell (suggested drops to ~7°C, with further 1–2°C decreases at night)

  2. Wrong mixing method: volume instead of weight

    • The speaker mixed resin/hardener by volume based on 4:1 (car-paint habits), but the correct process requires mixing by weight
    • They also state they did not read the technical data sheet first, so the correct weight-based ratio likely differed

Fix / recovery plan (as described)

  • Do not necessarily tear up everything
    • A technician advised removing only the spots that didn’t dry, then filling them and applying another layer if needed
  • Proposed method
    • Heat under-cured areas (already attempted)
    • Scrape off the top layer in affected spots using a spatula
    • Re-mix correctly, then reapply only in the scratched areas
    • If the appearance is still not satisfactory after repair, potentially apply another full top layer
  • Color mention
    • The overall color effect is tied to RAL 7040 (as stated by the speaker)

User experience / workflow observations

  • Framed as an amateur, first-time project, documented to show mistakes and how to avoid them
  • Decorative flakes can hide some imperfections, but the speaker is not satisfied and expects to apply another layer anyway
  • Weather planning mattered:
    • Work stopped due to cold: around ~7°C daytime, down to -2°C at night
    • Resuming only when conditions were closer to a safer threshold (e.g., ~15°C and stable)

Comparisons made

  • Against “tear it all off” advice
    • Community/forum advice often leaned toward full removal
    • Technician guidance favored partial tear-out + patching
  • Mixing comparison to car-paint habits
    • Epoxy mixing was mistakenly treated like daily car paint mixing, leading to volume measurement rather than required weight measurement

Unique points mentioned (complete list)

  • The epoxy floor was intended to be filmed step-by-step, but rework prevented filming the full application
  • Under-cured resin areas caused visible deformation/marks
  • Under-cured resin showed wrinkling/wrinkled surface and cracks at an angle
  • Soft spots persisted even after testing pressure (soft vs “rock-hard” areas)
  • Heat gun did not fix curing failure
  • Causes cited:
    • Low temperature (minimum ~10°C requirement missed due to cooler nights and days)
    • Incorrect mixing (volume instead of mixing by weight)
  • The speaker claims confidence in general mixing technique (mixer, low speed, scraping sides/bottom), but admits:
    • Failing the correct ratio method
    • Not reading the technical sheet
  • Repair strategy included:
    • Heating affected spots, scraping, diluting/reapplying locally
    • Possibly applying another layer (or more) after patching
  • Color reference: RAL 7040
  • Technician guidance: remove only undried spots; full tear-down may be unnecessary
  • Plan to wait for better weather; may delay work until May if needed
  • Intention to avoid repeating the mixing mistake; bought a scale for weighing
  • Decorative flakes cover some imperfections, but not enough to satisfy the speaker
  • A filming plan was split into two parts to avoid higher risk/work complexity in a larger room

Perspectives / contributors

  • Single speaker (main narrator): firsthand account of the failure, causes, and repair plan; mentions a technician and forum/community input
  • Technician viewpoint (quoted/mentioned): partial removal and patching is preferable to tearing out the entire floor
  • Forum/community viewpoint (mentioned): many recommend full removal

Verdict / recommendation

Recommendation: Proceed with epoxy resin flooring only if you can guarantee:

  • Proper temperature (minimum ~10°C during application and curing), and
  • Resin/hardener is mixed strictly according to the technical sheet—by weight, not volume

Based on the described video, the system can look great, but improper temperature + mixing by volume can lead to areas that never cure, requiring localized scraping/patching and possibly additional layers.
