A contractor called me and said that they installed a micro finish floor
in a basement and the homeowner called and said after about a month a
yellow stain appeared in the floor. The floor has 2 coats of thin, 3
coats of micro, sealed with CSS with a little charcoal reflector. The
floor is white. At first the stain was "highlighter yellow", now it is a
little more subdued, but a stain none the less. Also, around the stain
the micro is starting to bubble and crack. Any ideas as to what is going
on here?
