Prepping Plaster Walls for paint

19 years ago

I have a two coat system of plaster on the walls of my new addition and the plasterer told me to wait a month to cure the plaster then to use a pole sander to sand, then prime and paint. I'm ready to go now, and want to know if vacuuming the dust is all that needs to be done before priming. I sure want to do this right--I have no intentions of painting again in my lifetime!(Well, depends upon how long I live. . .)

Hi Vedazu,

STOP...DO NOT do anything to those walls for a month!!!

There's a lot of water in plaster, and it takes that long to harden-off. It's a very heavy-bodied product!
* If you primed/painted NOW, the water leaving the plaster will push-off your new paint job.
* AFTER a month, THEN sand, vacuum well, then prime.
* Then, TWO coats of paint.

Sorry, sometimes you have to wait!

Dear Faron,

As usual, I wasn't clear: it has been a month and now I'm ready to paint. I appreciate your response! Should I sand after priming as well, and what is the best roller out there to avoid little itsy-bitsies in the roller coming off on the wall? Thanks so much! Veda
