To fix mistakes: You will probably still have some bleeding that you need to touch up. What works best with latex paint is a little bit of denatured alcohol and some cotton swabs. This will take off latex paint pretty well, especially if it hasn’t had too much time to dry. This does not work with oil based paint though.
If the denatured alcohol doesn’t work, we used a light sanding pad to get into tiny nooks and crannies, especially the angled ones. If you take off stain from parts that are stained, you will need to re touch that area. We had a ton of this because of the oil-based paint and we had to contact the painters from our home build and find the exact stain they used. But it’s nice to have on hand because now we can match other wood projects we might want to stain to match later.
Almost all our mistakes had to be sanding down and re-painting or stained. My husband wasn’t satisfied with my attempts to fix it so he took over this project, being the perfectionist he is. So I gladly let him do it, even though it literally took him the rest of the year to finish. And he still has one section to go through and who knows when he will get to that! That being said, I’m so glad we did it. I love the look of the tone-on-tone and it looks so nice with all our wainscoting. I can’t wait until we can finally rip out the carpet and put it beautiful wood treads. But that probably won’t happen for awhile.
