These pinholes are caused by air bubbles formed in the epoxy coating during the application process. (some people mistakenly assume that they appear later once the floor has cured. This is wrong)

Repairing bubbles once cured is very difficult (or nearly impossible without needing to re-coat). Therefore the entire strategy for avoiding bubbles will need to fall on prevention of air bubbles. Over the years I have come to identify the key factors that can lead to the formations of bubbles in epoxy floors. Some of these I learnt the hard way, meaning that I encountered a cured floor with bubbles and needed to explain to the customer. And therefore I now make sure that most possible causes of bubbles have been eliminated before applying the epoxy coating.
