When you are undertaking an industrial floor coating project, you want to ensure success from the very beginning. Being prepared for possible challenges along the way will allow for a smooth project completed on time and without added expenses.
Sometimes, even though you’ve been careful about securing the appropriate materials and taking the necessary steps, problems occur. One of these is amine blush, a chemical reaction between naturally occurring carbon dioxide and humidity levels in the coating project area. The result is a waxy or oily haze on the surface of the flooring. While amine blush can be corrected, having to do so adds time to a flooring job, which in turn can delay the completion of the overall project and thus affect the revenue of the building owner. As you can see, amine blush creates a domino effect you’ll want to avoid.
But if you’ve done everything right, how can amine blush occur? Factors that appear to be out of your control play a key role in the development of amine blush. Actually, you can control these underlying factors if you are aware of them before you begin an epoxy floor coating project.
Monitoring and maintaining proper moisture and humidity levels in the area of the project is of the utmost importance, since humidity is a major contributor to amine blush. Monitoring carbon dioxide levels is also crucial. Did you know that the combustion heating system you use to dry the coating may be emitting large amounts of CO2 and thus allowing amine blush to occur? Avoiding such heating systems can greatly reduce the chances of this happening. Other ways to avoid amine blush include ensuring proper mix ratio, using slower-curing floor coatings (if time is not an issue) and using an inexpensive colorimetric amine blush test kit between floor coats.
PIP has created a technical whitepaper outlining potential epoxy floor coating problems and how to avoid them. Armed with this information, you can take the precautionary steps that will lead to a successful epoxy floor coating project.
