What is “amine blush” and why is it happening to me?
When epoxy coatings are applied in adverse conditions (usually high humidity), they can cure with an unintended hazy or greasy finish, known as an amine blush. This same result can occur in areas of high CO2 levels. So understanding and controlling atmospheric conditions is very important for your epoxy floor coating project and efforts in preventing amine blush.
You need to fix this problem.
Amine blush should be removed immediately for effective bonding and performance of your floor coating system. This will add significant labor costs and extend the timeline of your flooring project. But, you need to correct this situation now.
This is what you are facing with your floor:
| · Reduced cleanability | · Poor overall aesthetics |
| · Less stain resistance | · Tacky surface feeling |
| · Decreased gloss | · Compromised adhesion |
| · Trouble with recoating | · Quicker yellowing |
Your floor is the foundation of your business, so it’s important that it’s optimally performing as a key part of your team.
How do you fix this problem?
The recommended solution for removal is using either denatured alcohol or a vinegar wipe followed by a clean water wipe or rinse. However, most applicator contractors will decide to sand the epoxy to be sure all of this amine blush contaminant is gone. Then, additional coats of either epoxy or polyurethane can be safely applied.
Preventing amine blush should be your goal.
As an end user, how much does it cost to delay your production line to correct amine blush? If you are an application contractor, you are encountering additional expense and time to correct an occurrence of amine blush. Working together you can work towards preventing amine blush.
