drywall texturing/paint question

[RU482]

I had the joy of steaming down some gaudy wallpaper we had in our bathroom, only to find that the wall underneath is "less than perfect" , plus I did some more damage scraping the wallpaper off. It looks like the wall has a couple of coats of primer on top of the drywall. I'm thinking about using an air compressor and a broadcast sprayer to texture the walls and cover up some of the blemishes...can this be done over a primed wall??

thanks

Is replacing it out of the question? Sometimes hanging a new piece of drywall is better than fixing an old beat-up mess. If that's not an option, how about that southwestern adobe look that you see used sometimes? I've never used it, but I think you basically just throw on a ton of plaster, texture it with a trowel, and paint over it. Either way, good luck.

My wife took the wallpaper off of the kid's bathroom this fall and the wall under the paper looked BAD.
She ended doing some kind of sponge type imprinting on it and it looks great. You can't see the flaws
that were in the walls at all.

if it is really bad they make 1/4" drywall. Rememer, if you go that route, you will have to extend the jambs on any doors and windows along with needing thicker mudrings on the outlets.

But it is way easier than a skim coat.

Eh, not recommended unless you modify the standard texture mix.

See, going on regular paper that's on gypsum board (drywall) or a skim coat (using hot mud), the texture sticks really well so you won't have adhesion problems or pieces coming off with wear-and-tear. Going over a latex or other sort of primer, the texture will not adhere as well, especially if it's a thick one. Note, it will still work, but use care.

Several ways around this.

1) Modify the texture mix to include an adhesive or a latex/acrylic additive to increase how well it sticks (you can use this instead of water).

2) Increase the size and thickness of the texture to ensure stickage.

or use a plain skim coat of hot mud. Evadman, I disagree. I think it's cheaper and faster than drywall. I've skimcoated a 10x10 room in about an hour in preparation for a knockdown.

If you want, spread the texture over the primed wall, then smooth it out as if you were doing a knockdown with a nice trowel, at least 12". Let that dry, then cover it again with texture and that way it will stick better because of surface area.

Hope that helps. Honestly, it should work straight onto the primed wall, but try it on a section and see. Texture sticks well, I've found.


Cheers ! 🙂

an hour including sand time? I took the question as redly trying to fix the look of his walls, not apply a textre. the texture was to hide the problem.

Ah, good point. Nah, I was doing a knockdown and needed a base so I just troweled on the stuff. Plus, it was an easy room, few corners and plenty of flat space. 1/4 inch drywall would do the job if a flat finish is desired. Then you're right, skim coat would be too much hassle. Waaay, waay too much.


Redly, I still think it will work if you just spray it on and paint over it.


Cheers ! 🙂

If it were me, I would do a quick skim coat on it, them apply a concrete block filler type paint as my primer coat for the new paint.
