Painting on cardboard like drywall?
 
Hi there guys, new to DIY Chatroom. There was a leak a while back and it damaged one side of our wall pretty bad. I went on ahead and peeled off the paint. There is this cardboard like substance on the wall. I'm pretty sure it's dry wall, I think. I'll provide with a picture. I'd like to know how I'd go about fixing it and preparing it for paint. Thanks guys.

Just get some Hot mud, let dry, sand & feather, finish, repaint. Easy one day job.

That might work.. or the moisture in the mud will cause the paper ( its a covering paper over the actual white gypsum that sheetrock is made from) to bubble .
What I do is coat it with something that will be a moisture barrier- Oil primer, a waterborne primer called Gardz or pigmented Shellac- called BIN. then taping compound (2x) , sand, prime and finish.

What brushjockey says ... Plus use a utility knife to cut round the drywall paper to make sure there are no loose parts which happens if you just try to peel it back.

I'm not 100% sure that's drywall, looks a little like masonite (hardboard). Kinda immaterial though as what Brushjockey posted would work fine in either case.:)

Thank you guys so much! Is this a good sealer (1 gal. besides 1 qt.)?
"Kilz 1-Gal. Oil based White odorless Primer"- http://www.homedepot.com/h_d1/N-5yc1...&storeId=10051

It is not the best but if you already have it, it will work( maybe):whistling2:

Taping compound is like spackle only made for finishing drywall. Spreads easier, sands (usually) easier. Plus three is a very popular one. You can get it in small amounts ( maybe a qt- for sure a gal) . Use as big a mud blade as you can- I would be using a 12" and a 3" to get it out of the pail and onto the big blade.
Look for it in the sheetrock section- not the paint dept.

looks like sound board to me. Which some people get confused an install instead of drywall. Its meant to be installed UNDER drywall
