Which is the best finish for walls – flat or satin (eggshell)?

Always require your painter from whom you get a written quote to specify on the contract which brand and grade of paint he/she will be using. Confirm before you sign that you are getting a high-grade, washable flat finish, then check the cans when they show up on your job site that they are the same as the what the contract specified. This is a way to ensure you are getting a professional painter in Lexington to paint your home.
