Epoxy floor installed in basement — bubbles, texture issues, and hard debris chunks. Professionals, is this normal or a bad install?
Had an epoxy floor installed in my basement this week by a licensed contractor. Two rooms — kids playroom and home gym. Total cost $7,000.
Before starting, the contractor mentioned the concrete was softer than expected and that vapor could come up through the slab. He applied a thick black base coat to address it, then came back the next day and applied the color coat.
I noticed bubbles forming during the base coat application. Now that it's cured I have:
A rough, pitted texture with tiny marks across the entire floor
Several hard, jagged black chunks embedded in the epoxy that appear to be concrete debris from prep/grinding that wasn't cleaned up before coating
Overall uneven, cloudy appearance
My questions for anyone who installs epoxy floors:
What likely caused the widespread bubbling/pitting texture?
Is the concrete debris/hard chunks a normal occurrence or a workmanship issue?
Is this a fixable situation or does the floor need to come up entirely?
Would you consider this an acceptable finished product?
