I own a home that was built in 1890. I am working to restore the dining room. I am at the last step which is dealing with all of the painted trim. There seem to be over 7 layers of paint on the trim, and it is all cracked. What advice can you give me for being able to paint the trim without the cracks coming through again? After reading several posts - I am sure that lead paint will also be an issue. Thanks for your assistance!
