The reason I don't use PVA is because of the time involved in a product change.

It really doesn't matter, do what you want.

Brush, roll 3 or 4 coats of finish, First acts as a sealer.
Or brush, roll 1 or 2 coats PVA. Then 2 coats of finish.

You are going to have to buy 2 or 3 gallons PVA and then 2 or 3 gallons finish.
Then get stuck with 1/2 gallon PVA at the end of the job. Finish you will keep.

Or just buy the finish and have no PVA left at the end of the job.
White over new drywall will require at least 3 coats.
Do yourself a favor and buy a 3/4" lambswool roller, frame, a five and a screen. Don't use a tray and don't use a short nap roller. You can wash the lambswool, five and frame, and it will probably last you forever.

If I was you I would just use finish, from start to finish. It makes cut in easier, coverage easier and product purchase easier.
If you are just using white, buy 4 singles and then go from there. You may have to buy 1 more, you may get to return 1.
God luck.

Damn good advice here. It amazes me how many people think they'll get a good finished product with a cheap roller and pan. You get what you pay for.

Another benefit of the 5 is to mix multiple gallons together as you paint. Especially with tinted paint, there might be slight differences between gallons. Dumping several at a time into a 5 minimizes the difference.
