Priming interior sheetrock before painting

Ready to prime before painting walls a satin finish and would like to know if I should use a specific roller. I am looking for a smooth finish and not sure if I were to use a nape type roller if the satin water base would flow and cover any residual texture the primer may leave. Using the heavy duty 1-2-3 type primer which appears fairly thick. Input suggestions appreciated!!

Assuming light or no texture, I'd use a 1/2" nap roller. You could use a 3/8" nap but it won't hold as much paint as the 1/2" [won't apply the primer/paint as quick] As long as you do a decent job of rolling the minute roller stipple won't really show, sanding the primer will help to eliminate or reduce the roller stipple.

Don't forget to remove any sanding dust before priming!

Yes, thought I would paint the living room walls without any texturing. If understand correctly, any 'roller stipple' after applying the primer can be sanded out? I was not aware I could sand after applying the primer, that's very good to know!! I will purchase a couple 1/2" rollers for applying the primer, and couple more for the water base paint. Appreciate the input!!.

There will still be some roller stipple, the only way to completely eliminate is to either brush the paint or spray it on. A slight roller stipple makes the walls look better as it will help to hide [or at least not accentuate] any minor defects in the wall and also makes touch up easier to hide.

Basically a light sanding of the primer promotes better adhesion of the top coat while making any roller stipple less noticeable. While all/most of the roller stipple can be sanded out - IMO that's more trouble than it's worth!

Thanks much, if after applying the primer coat nothing significantly stand out and the primer coat thoroughly dries intend applying couple coats of the satin and leave well enough alone. Thanks again found info very helpful!!
