Greetings! First thank you for the taking the time to check out this post. Here's my issue: My father-in-law decided that he wanted to paint our hardfloors with a high gloss, high build polyurethane coating (I believe the product used was minwax). After completing the job, the polyurethane coating developed what can best be described as a shattered-glass look, or almost like a spider-web effect. It appears that the polyurethane is cracked. Has anyone here ever heard of this and if so, thoughts on how it might be able to be fixed? Any help would be immensely appreciated! Thanks again for your time!
