The interior walls of my 1951 house are plasterboard coated with a very deeply textured plaster. I'm sure they've had many coats of paint over the years, the last one being done by prior owners, obviously with a coarse brush, because the brush marks are obvious everywhere.

The reason for using brushes throughout was likely because the texture is too deep to cover well with a roller.

I need to start repainting certain areas. Question is how best to do it.

I do have an HVLP gun and compressor. Is that likely to work, or will paint just drip from the deeper crevices?

I could try a very long nap roller, but since there are also a lot of very smooth areas in the texture, I'd worry that would make those areas look oddly rough or stippled.

Any thoughts?

Roller cover to use: wooster superfab 1 1/4". It'll do the job nicely. to make the whole job easier on you buy a wooster 9" surelock frame and pole system.

i'm currently doing our living room with texture that does not sound as bad as yours, but is still a PITA. after reading some posts here and doing a bit of research, it seems our painting technique was crappy. get the correct nap on the roller, load it up and always roll with a loaded nap. forget the "w" formations and rolling all over the place with tired arms. load it up, roll up and down gently placing the paint on the wall, and when the paint trail starts to fade, re load the nap, do not push harder on the roller. I'm not a quality painter by any stretch of the imagination, but feel like this recent change is faster, less tiring and better coverage.

now cutting in, that is a pain in the rear on heavy texture. I'm sure others can talk about paint quality and where to get it better than I can....

The advice you have gotten on the roller nap is correct. But although coverage will be OK be aware this will not take care of the problem of the coarse finish from the previous job.
