Old damaged wall - Can this be fixed?
 
Hello,
I am new to DIY so please forgive lack of professionalism.
I had some boards installed over the wall and after removing them in some places old paint got removed together with the first paper layer that is attached to the drywall. Also, when I sand the wall to prepare for painting, many times some of the paints goes off with that paper layer. It looks like in the attached photo.

What is the best way to prepare the wall for paining.
This is a bathroom.
I will be changing color to light yellow.

thx

If it was my job I would cut out that whole section of drywall and start with a new piece for a nice flat surface.
I know you can also cut away any loose paper and go over the whole area with at least three thin coats of drywall mud and sand it out, prime and paint it, but I've not had much luck having it come out as well as a new piece.

If you opt not to replace the drywall, you will need to scrape off everything that is loose and prime with Zinsser Gards before you do your repairs. Use All-Purpose Joint Compound to repair the wall and re-prime with Gardz after you have done the repairs. It's not an easy job, but it can be done.

This sure beats removing the drywall and re placing it as Mr Joe would like to do. :yes:

So , you think i cannot fix that without putting new boards?
What if I paint this like in this photo.

Would this be possible with this wall?
How do I accomplish look like that?

do I apply the Primer Whole walls or just parts where I used the compound?
I assume compound goes where drywall was damaged and then primer over everything?

Mr. Paint 03-20-2012 05:39 PM

If you have removed the face paper of the drywall, you will need to prime just the damaged areas before you repair with joint compound. When the compound is sanded flush to the wall, then prime the whole wall.

thanks for your help,
so when i clean the wall i should not force the removal of the face paper,
just nicely sand it, then put primer, i ask as every time I think all is smooth and ready for primer i see some face paper sticking out, i assume primer will glue it back?

blwegrzyn 03-20-2012 07:16 PM

What sandpaper number or type do you recommend for sanding?
And lastly i wonder what would you use to cover the holes between drywall and the doors?
Should I use acrylic caulk here and then cover it with compound mix later before final primer?

Check at your library for books on faux finishing to learn how to do this. It is not my thing and it can get out of hand in a hurry especially if the faux ends up totally out of context with the home.

I do remember one series that I found helpful. See if you can find "Recipes for Walls". I know there were at least two volumes and there may be more.

blwegrzyn 03-21-2012 04:28 PM

anyone can recommend what is the best to cover the holes between the door and wall in the picture above? Caulk and later compound and primer?

user1007 03-21-2012 06:52 PM

Ordinarily, trim would go over the wall surface. Whatever you decide to do is going to look a bit weird I think? :eek: I guess, if you must go for the embedded trim in wall look? Hot mud to fill in the major gaps and then caulk.

When I bought this place it was already like that.
Whoever did the condo conversion decided to cover all walls with new drywall.
Under that drywall there is plaster wall.
Undecided to strip all doors from old pain and re stain them.
It looks nice but crazy part I that like you've said the trim is embeded.
I don't have a choice and I have to fix it somehow.
The holes are leftovers from stripping the paint.
I wonder if I maybe just should use only hot mod and cover with primer and paint so the color stays the same. I don't know how caulk would paint but would not it be better to paint over primer?

blwegrzyn 03-23-2012 11:09 PM

so I applied the Zinsser Gards:

before:

after:

The next step is the all purpose compound and then just to verify Gards again?

Why not regular primer?

thx

Feel the Gardz- you'll notice that it absorbed into the brown material, and now has a coating that is impenetrable with water- much like an oil. The mud you put on will not be able to soften up that paper which would loosen up and bubble with most other primers.
This is one of the main purposes that Gardz was invented for.
