We have three little kids with dirty little hands. Thus, I decided to paint the walls of our new house with semi- gloss paint. THis was great until we then had to have a lot of drywall work done AFTER the paint. Now, despite the fact that the new sections have 4 rolled coats of paint on them, they still look completely different from the original sections. Are we totally horked, or is there something I can do to get the textures right?
