This presentation explores problems that may arise during the application of industrial flooring works. Epoxy floor coatings are amazing products that can provide great benefits to industrial and commercial companies. However just like many other great building products if the product is not applied correctly, the installation will fail, causing severe operational problems and headaches to the end-user. This presentation identifies the seven key reasons. Visit for more information

Seven reasons why epoxy floors fail

  1. 1. Seven reasons why epoxy floors fail
  2. 2. Epoxy coatings are fantastic products that can create great seamless resinous floors
  3. 3. And yet….
  4. 4. Many times things can go wrong when applying epoxy floor products….
  5. 5. So what causes industrial flooring projects to fail?
  6. 6. Here are the top 7 reasons:
  7. 7. 1. Poor surface Preparation
  8. 8. Always grind (or shot- blast) the surface before installing the new floor! 1. Poor surface Preparation
  9. 9. 1. Poor surface Preparation A surface needs to be properly prepared. This means it should be • clean • dry • dust-free and • the substrate must be ground or shot- blasted
  10. 10. 2. Humidity
  11. 11. Solvent based Epoxy products do not bond well with humidity 2.Humidity
  12. 12. Make sure that • the surface is completely dry • no pipes or taps dripping • no rising humidity from beneath the ground. 2.Humidity
  13. 13. 3. Weak Substrate
  14. 14. This happens when the Epoxy floor product is much stronger than the substrate (for example low –quality cement) What ends up happening is that you don’t actually have the epoxy layer detaching from the cement 3. Weak Substrate
  15. 15. but the cement detaching itself from the cement. (for more information on substrate failures click here) 3. Weak Substrate
  16. 16. 4. No (or wrong) Primer
  17. 17. 4. No (or wrong Primer) Always use suitable primer for Industrial Floors!
  18. 18. Floors experience heavy wear and tear Don’t assume the industrial floor screed will simply just stick to the substrate. Always make sure that the primer is suitable for the substrate 4. No (or wrong Primer)
  19. 19. 5. Incompatible Surface
  20. 20. Make sure the substrate is compatible for epoxies both in terms of adhesion as well as tensile strength. 5. Incompatible Substrate
  21. 21. For example never coat epoxy on wood! Wood is far more flexible than epoxies which leads to the epoxy cracking simply because it cannot follow the expansions of the wood floor. 5. Incompatible Substrate
  22. 22. 6. Contaminated Floors
  23. 23. Such problems occur in old installations (for example food and drinks factories, car service shops, workshops) that want to install an epoxy floor coating over the old contaminated floor. 6. Contaminated Floors
  24. 24. 6. Contaminated Floors All oils, greases, residues must be properly cleaned before attempting any type of fresh coating. Don’t expect proper bonding otherwise.
  25. 25. 7. Faulty Resin/ Hardener mix
  26. 26. 7. Faulty resin/hardener mix Ever seen the coating not cure properly? Did it remain sticky or soft long after the application was finished?
  27. 27. 7. Faulty resin/hardener mix This was caused by a faulty mix between the resin and the hardener: - Mixing incorrect or inaccurate proportions of the components - Not mixing the material properly or for a long enough time (click here for more information on sticky epoxy)
