Or... sand down the biggest offenders, paint, and move on? Your kid probably won't care and may well leave wall souvenirs of his own...

We allowed our daughter to flick six different colors of paint all over her room and found the easiest, cheapest way to smooth the walls before repainting for selling the house was to have them skim coated with plaster by a pro painter. It didn't add much to the cost of the job, but wasn't something we could tackle ourselves.

What Lyndee Lee said....get a flat razor blade scraper and scrape the walls, I do this every time I paint to get any roller marks off or raised areas. My house came with very bumpy walls from previous owners using a roller for rougher finish. I have been gradually getting them smooth with the scraper and a pole sander.

Your local paint store should have these scrapers. They have 4 inch blades and a long handle about 12 inches long. Put a bright light on the wall and scrape all the raised areas you see. It will quickly slice off the extra paint way faster than sanding. Then you can go over with quick sanding pad to blend. Very easy and quick.

editing to add that I am not talking about the paint scrapers that are 2 bladed. I'll insert a link...https://www.homedepot.com/p/QEP-4-in-Floor-and-Wall-Razor-Scraper-with-5-25-in-Handle-and-Stainless-Steel-Blade-62920/311182302?source=shoppingads&locale=en-US&&mtc=Shopping-VF-F_D23-G-D23-023_014_FLOOR_TOOLS-NA-NA-Feed-SMART-2150536-WF-New_Engen_PL3&cm_mmc=Shopping-VF-F_D23-G-D23-023_014_FLOOR_TOOLS-NA-NA-Feed-SMART-2150536-WF-New_Engen_PL3-71700000084477446-58700007168062760-92700064419903686&gclid=Cj0KCQiAuP-OBhDqARIsAD4XHpeZXuQYZ2qWi3KytW96QH2OrRT2WY5fncsMGIDnYwEYL1NCQIHgAGAaAh1AEALw_wcB&gclsrc=aw.ds

I hate ignorant comments. This isn’t Facebook. Of course my kid won’t care, he’s 1. I care. And I don’t want to half ass it like people do apparently. I also don’t want to leave it until I sell. I want to fix it. Not sure why that’s such a bad thing. Anyways.

Thank you cleo. I took a look. I have a wallpaper scraper that looks a lot like that. Will I get by with that or need that specific tool? (Which is fine. Just don’t want to spend money if what I have will do)

The wallpaper scraper you posted is essentially the same as the one Cleo posted. Try dull blades and sharp blades to see what works best. You will likely Damage the paper face of the drywall so you will want to seal any exposed paper with shellac or oil based primer before you start skim coating otherwise the mud will make it swell.

Yeah someone did a paint splatter effect on the walls not thinking what it would led to in the future.

My sister and her young daughter came up with a great idea of painting huge polka dots all over her bedroom in bright colors. Then they decided to put house up for sale and were repainting all the rooms with neutral colors. The paint polka dots had to be sanded down with a electric hand sander, primed and painted to make them go away.

Thanks all! The wallpaper scraper did an okay job but I ended up just getting an electric hand sander and did all the walls that way. Still battling the glue. I did take a nice portion of the drywall off with every other method, obviously not ideal, so I stopped doing that. The sander tends to melt it of course, which actually makes it easier to scrape off. So for now that’s what I’ve had to go with (using an old sanding pads so I don’t ruin my others) Thank goodness this is just the one room! (They all need some touch ups but this is by far the worst!) Hoping to finally get painting next week.

Izzy - My kids have a nice sized playroom and I wanted to put round circles on the wall but thankfully I thought of that haha! And am going to do them out of wood, paint funky colours, and then affix to the wall. In the first home we built, I did stripes in a bedroom and feel sorry for whoever had to sand that down to repaint the wall. I didn’t think of it when I was doing it, of course. I have a similar issue in my dining room where the upper half was painted and the lower half was wallpaper. Plus what wasn’t painted under the trim. LOTS of sanding in my future! Haha!

Excuse me asking but why are you sanding the paint color off the wall? Isn't primer supposed to neutralize color?

Did you double check that the glue is not water soluble?

Take a pill this is always going to be a formu where people have opinions if you don't want opinions don't ask the question. IMO the best is the scraper with the razor blade and after you get rid of the biggest offenders prime the walls and paint honestly no one will notice every little speck and as said your child will add to the character of the walls .

Goo Gone makes a remover for 'stuff' that ended up where it wasn't supposed to be. Maybe that would help.

@ Rho Dodendron (I have no idea how to tag in this app) If you read the thread, there’s paint flecks all over the walls. Like someone took a brush and whipped it at the wall. So I’m trying to sand all those bumps down.

@ Patricia Well I expect Houzz to be a little more professional in nature. Not like I’m on Facebook with a bunch of keyboard warriors. It’s possible to act like an adult and stick to the question asked, instead of adding irrelevant and ridiculous personal opinions that don’t address the issue. Apparently not, though!

@ Colonel - Wish would have thought of that sooner! 🤦🏻‍♀️
