If your taper is doing that much sanding, there is a problem, we never have to sweep the walls. after the final coat, we prime, if anything shows up after prime, we touch up, spot prime, and away we go....

It doesnt hurt to sweep the walls, at leas at eye level, it doesnt take long.

use a 415 to 517 tip to spray and backroll with an 18" roller setup.

light sand on walls after prime and away you go!

Glad I don't laim to be a taper. I will at least do some dusting . Have been known to use a damp rag as tack rag to wipe with. I tack when I am concerned about the dusting from a brush or dry rag causing the dust to become airborn and settling back on th ewall or bb's.
I'm beginning to appreciate the dustless dw mud.

Ditto.
I also like to use a pva primer, especialy when dealing with darker colors.

thats the way to go. Use a pole sander and it takes 5-10 minutes to do the whole room, about the same time it'd take to sweep the walls.

Worst case sceanario when your painting over a lot of dust. You end up with a lot lil bumps which will be small and many if sprayed or big and few if rolled. Then again worst case scenarios get a 12 in knife scrape the whole wall then 2nd coat.

Why do you back roll with an 18" roller

Soloplayer

18 inch roller is more efficient than a 12 inch roller on large walls or ceilings.

first of all, you DONT have to prime bare drywall.....you have to UNDERCOAT IT ...........if im doing a B/R renovation top to bottom new rock ill roll the entire room with ceiling white once then hit the ceiling 2 more times (sometimes only once more if it covers) then ill roll 2 top coats on the walls with whatever color they chose ......... then ill do the trim .....then ill get paid !!!

I have to disagree. This has become the shortcut for painters trying to compete for work these days(price-cut) First thing you need to do is read the ingredient label. Ceiling paint and Primer have different chemical makes. Second, it comes down to the pricing. A good primer tends to be 1/3 more per gallon over the price of even a decent ceiling paint. He has the two coats of topcoat right, but the trim should be done first. Then you cut the walls back into the trim. Notice the exclamation on getting paid. There is a reason I paint 5-10,000 sq. foot houses. You don't just hand over a 1-7 million dollar house to anyone. Also, most rollers are 4,9,and 18. I recommend Wooster Polar Bear. If your new to the game it will teach how to roll. If you have further ?'s feel to ask. I am just here to help the consumer. I am tired of people wasting money and fixing other painters messes.

I agree with you Matthew. Once walls are clean and dust free, prime walls and ceilings using acrylic primer. Finish paint ceilings with two coats of paint. Paint trim (primer and two coats of paint also) then finish paint walls with two coats of paint. Always sand after priming, walls and trim.

At the risk of making enemies here I say right on Matthew! If you're going to do the job you might as well take the time to do it right the first time- save money by not having to go back for a repaint. Every job you do affects your rep and you'll be remembered first for any bad jobs or peed-off clients.

I agree with you Floyd, PRIME PRIME PRIME there is a reason for primers . I have done it both way over my 40 years and agree that priming is the RIGHT WAY. Also agree on dusting the ceiling and walls , would you paint over a dusty surface... just my two cents worth
