Just had my bathroom painted. A couple weeks later I noticed that the paint on all four walls had small cracks everywhere. Thousands and thousands of small cracks everywhere. It appears the paint has separated. It appears to have expanded or contracted and not stayed together in a smooth uniform continuous layer. Thousands and thoausands and more tiny cracks. What do you believe caused this problem and what do I do now to correct it? We have repainted this room in the past and have never incurred this problem before. Thanks for your consideration! Steve
