I used a 45 minute medium compound instead of drywall mud. I realized my mistake and have tried to scrape it off. It now looks terrible.

Can I now used the drywall mud to smooth it out?

    What, precisely, is the product you used? "Setting" drywall compound would be fine (but then, why did you consider it a mistake?) Artists medium would be less suitable. It's unclear what you actually mean.

If you are referring to a fast setting joint compound that comes in a bag and mixed with water? Yes you can. I typically use the fast set mud since it does not shrink much and sets fast, so I can add a coat of regular mud over that since it is much easier to sand than the fast set mud.


If you applied too much, you need to sand it off, not just apply more of another product.
