I recently plastered my bathroom walls and applied a coat of dry wall primer. I waited a week and applied latex paint. Seems like the paint is picking up the plaster.

I read that I should have used acrylic primer. I only painted a small section behind the where the toilet tank will sit.

Can apply acrylic primer to the walls over the dry wall plaster or do I need to apply another layer pf plaster first.

Second question: I am looking for a Santa Fe look on the wall. What is the best way to apply the latex paint once the wall is ready? Roller, brush, falt applicator?

Hey Mike,

Do ya mean "USG All-purpose Joint Compound"?

** Did you do a texture-sprayer to apply it; or a broadknife?

** How long did you wait between your joint-compound application and the primer??

** What do you mean by "the paint is picking up the plaster"??

Let me know when you can...

Hey Faron - thanks for the response.

-Yes it was All-Purpose Joint Compound.

-I applied it with a broard knife. Has a bit of trouble with bubbles. I'm learning.

-I applied the primer about five days after applying the compound.

-When I painted the ceiling I tested the walls a little and I found that my paint brush seemed to be picking up the compound as I brushed accross the wall. As if the paint was softening the conpound and then my brush picked some of it up. When I went back over the area with my brush and then lifted the brush a residue would be left behind thicker than paint.

I can replaster the walls if need be. It's the first time I've plastered and I want to learn it right. I've learned to tile, dry wall and many other things. My learning curve is nearly verticle.

Thanks for whatever advice you can provide.

If you sanded the walls and did not get off the dust from the drywall compound that would give you what sounds like your problem. If that is case then you will need to wipe the walls down to remove the dust before you prime them with the latex drywall primer.

Didn't sand the area I tested but I did do some sanding in the room and dust may have gotten onto my test area. I'll wipe down the whole area.


* I should apply a new coat of primer first?

* Should I use Acrylic primer? I plan to paint the walls using a Satin latex based paint.

* Should I sand after I apply the primer?

How long should I let the compond dry before applying primer and how long should I let the primer dry before applying paint?

I wonder what you did to the wall in preparation for the joint compound/SantaFe treatment....Were you following directions or just experimenting ?....and what is the original wall....plaster or drywall...was ther ever wallpaper installed...

I suspect that now your primer needs to be oil-based.....

All-Purpose Joint Compound "dries" to a soft water-soluble finish.....

Plaster and Setting type compounds dry hard and cannot easily be re-dissolved.....

My opinion......worth price charged:

The action of your brush and Latex paint dissolved the edges of your poorly prepared wall/water-soluble joint compound........

especially in a bathroom..... just cover whatever you have with a barrier of good oil-based primer....dry and then your choice of latex top-coat

"...measure once.....cut twice....throw that one away and cut a new one...."

The oil based primer may very well be the way to go to create a barrier from the moisture. You allow joint compound to dry at least 24 hours before you apply paint to it and as far as the primer dry time just follow the directions of the product used,but do not use a fast dry stain kill type primer as they dry to brittle for this application.
