Why did your epoxy coatings bubble?

Posted by Pedram Mojarrad on

Have you ever seen bubbles in epoxy floors? do you know why those pop up at all? Bubbles don't look good in what we expect of resin flooring systems (seamless, consistent looking coatings).     What are they? These pinholes in the coating appear as small blisters or bubbles. After the blisters pop, they leave round bowl-shaped bubbles that can be seen through the transparent film.   Causes: 1- Outgassing: Air can escape from the porous substrate and becomes trapped in the coating. So substrate preparation is really important here.  2- Temperature/Humidity: If too hot or humid, it can result in rapid drying...

How to Paint a Concrete Floor With Epoxy?

Posted by Pedram Mojarrad on

Epoxy flooring is a durable solution for concrete. Not only does it prevent concrete from ingress of aggressive ions, but also gives the concrete floor a much better look. But it can be a bit tricky. Have a look at our checklist as follows:     Check For Moisture Check for existing moisture issues. If your slab was originally poured with no underlying vapor barrier or you have high ground water, it’s possible for water vapor pressure to actually lift coatings off the surface. Tape a 50 x 50 cm piece of clear plastic over the slab and leave for 24 hours. If you...
