My family and I recently decided to sand, stain and polyurethane my entire upstairs floor. We let the stain stand and dry for a week before applying the polyurethane so that can't be the problem. However before using the applicator for the poly, it was recommended that it be rinsed with water. The applicator may have still been wet during application and now cloudy spots are seen all over the floor after the first coat. How would we fix this without stripping? Any help is appreciated, thanks alot.
