Can you put drywall compound on top of a painted wall?

the wall has alkyd primer + acrylic latex paintCan you put drywall compound on top of a painted wall?
when they build houses they stray an acryllic primer and then the drywall finishers point up the house... fix all the nick and scratches in the wall.. once the house is painted and the new owners do the first walk through.. durring this time they will mark the walls some how so that the contractor knows what to fix.. then the point up guys come back.. they spread the drywall mud on the paint then sand then paint ..


the only place that i have ever seem it fail is on an outside corner where there is a large amount of drywall mud for a repair.. if it is bumped it can chip.





if it is a really slick paint you can use a sanding sponge on the area first to create a texture for the drywall mud to grab on to. the only problem that i have ever had with repairs is a lot of the time at the right angle you will see a differance in texture where you put the mud from another part of the wall.





you can also use ';ez- sand'; try have it from 20 to 120. thats approx mins to it starts to set up. use the highest if your not use to it... add a little to your mud to give it a faster dry time, and also more time to work with it then just straight ez-sand.Can you put drywall compound on top of a painted wall?
For a large hole or spot of damage a better idea is just to cut new drywall or it. But if its a small wound then drywall compound is fine. You just have to make sure you sand it down to be even with the rest of the wall and the right color paint to do the touch up. I would suggest doing at least a minimum of 2sq ft. of painting around the area as well if you can't afford to paint the entire wall. Even if you buy the exact same paint color and style it doesn't have the age and wear and tear as the other paint around it and it will stand out like a sore thumb.





Sand the area. Fill it. Sand it. Paint it. You'll be ok.





Good Luck.
Yes, in small area's. Be sure to sand the area once the 'mudd' has dried, or you will get a rough look- with high gloss paints, you may have to sand the area to get the texture to stick.
You can, but it won't adhere properly, so it's not recommended.
