Update, the finish over white spots had bad adhesion, in some white areas there was white powder like crystalization. Still not sure what exactly happened. Wax..dog urine..., ? We scrapped the white areas out, stained, returned next day to build finish, 25% white spots returned, we pbunched some through and filled making it look like distress and knots and used a black analin dye on some that was scattered over entire board. Then we coated again. Adhesion was good, thankfully it was a reclaimed pine floor that looked better with more distress and knots. Didn't make a whole lot of money on that one![smile]()
