Priming under knock down ceiling texture
Fbart
| Posted in Construction Techniques on
I was just given a job which includes knock down texture on the ceiling and walls of a multi room building. I have done several ceilings before and have always primed the sheetrock with primer paint first. I have however seen it done without priming first, and then priming and painting over the finished knock down texture. Is one way better than the other? And if so , why? Any help is appreciated.

Funny you should ask. I have the same question. For years I always just blew the texture onto unprimed drywall. Never had any problems. Recently I read and heard thru the grapevine that you HAVE TO prime first. On my most recent project I primed first and then put on a heavy orange peel and then primed again and then normal painting. I did not see any advantage and sure don't like priming twice.
I do have an open mind and would like to also hear from others.

The reason we prime before we spray is because the drywall compound absorbs the moisture out of the spray faster than the unmudded parts of the drywall. If you are doing a great big room, everything dries slower giving you a longer work time. My 2 cents anyhow.
I have also heard you prime first to one reduce the shadowing underneath from the white compound and the gryish drywall as well that the primer seals any dirt, oil, dust on the sheet rock for bettter adhesion.
Thank you gentlemen for your replies. We spryed the walls and ceilings today, without priming, at the suggestion of the GC., and they look good at this point. It will be interesting to see how they look after painting.
Most people do as you have done .
