    Default Prep work before painting

    Greetings everyone!

    I am currently working on renovating a bedroom of a split-level house built around the 60s. I removed all of old trim from the windows, doorway, and closet. There is a thick layer of paint where the old trim met the wall forming a slight bump. Should I smooth this out before installing new trim? Should I sand it? Should I use joint compound, spackle, etc.? I am not sure if the paint underneath is lead based, but I would prefer not to sand and expose that layer of paint from when the house was built.

    Thanks in advance for any advice and suggestions!

    Is the new trim wider, the same width or narrower than the old trim?

    use a putty knife to sc**** the bump off and hand sand if needed to keep the dust down. install the new trim then caulk where the trim meets the wall. paint the trim then you can cut a nice straight line of paint down the wall where it meets the trim.

    The new trim will either be the same width or wider. (I haven't picked it yet.)

    MLB,

    I actually started down this route, but found that some paint was coming off in large chips down to the plaster. How should I even out these chips?

    Carefully sc**** the paint ridges as flat as possible, then install your same width or wider trim. When you caulk the new trim, it will hide the remnant of the old paint line. If the new trim is narrower, then you'll want to scrap it as flat as possible, then float with drywall topping compound, lightly sand to blend everything together nicely.

    Large peeled patches, remove what is loose, then float the area with topping compound and sand smooth. Multiple thin layers work better than single thick layers. Don't be too aggressive with your sanding, just enough to blend the patch into the wall.
