This was my first time using micro cement and it was on a shower ceiling which posed all kinds of challenges. I had multiple questions, more than once, which they were always happy to answer. When I ran out with 1 square foot left (yes, really....) Epodex customer service was extremely helpful in getting me what I needed and describing how to finish the project without taking 10 steps back. It turned out great, and now I have some valuable experience!
