Do I Need To Remove Drywall Dust Before Priming

TheSMJ join:2009-08-19 Farmington, MI	Member 2014-Aug-4 10:42 am Priming fresh drywall - go out the grit? Concluding week I had some freshly installed drywall mudded and sanded professionally. Sinec I didn't feel like spending an actress grand on the painting and priming, I decided to do that part myself. One thing that struck me as odd, is the guy who did the work recommended I leave the dust on the wall, and utilise a 3/4" nap roller to apply the primer. He said the grit volition mix in with the primer equally it's rolled on, and go out a better finish which the paint volition adhere to. Then, he said I should lightly sand the walls and put on a couple coats of premium paint (I bought SW Superpaint). This is the start time I'd heard of leaving the dust on the wall, and using such a large nap roller for applying primer. However, I'd done the ceiling this way, and then far it looks pretty good. I'thousand not sold on the idea of needing to sand the primer since it's already flat and designed for paint to be applied, merely if information technology's actually necessary then I judge that'southward what I'll do. Has anyone else heard of doing this?

As far as the dust, the just matter I've heard is that unless there are merely large clumps, you don't Accept to remove it. I accept not heard that leaving it improves anything though. Use a PVA primer, that is the virtually important thing.

What about sanding the primer? I didn't find any reason to sand after the PVA but I know some people do a light sanding then do a 2d coat of PVA. I simply did ane coat of PVA so 2 coats of paint.

If I were to return the latex stuff (which I believe I can practice), should I redo the ceiling which I already completed? I'm sure yous tin employ the latex stuff but it's just super expensive compared to PVA. A 5 gallon bucket of PVA was the price of 1 gallon of pigment like $35-40. I'd guess that latex primer is far more than and so $9 a gallon. The PVA primer is for new drywall only and then if you already did the ceiling it should be fine.

In my previous career, I was a pigment contractor. What we did was dependent on the desired end level. If we were shooting for a high-end, super smooth finish (aye, fifty-fifty on walls), then nosotros'd lightly grit and definitely sand between coats, just to knock off any droppings and texture that may take remained. Yous don't need to be overly thorough or too concerned, unless you lot're doing fine- finish work such every bit trim, casing, cabinetry, etc.

There may exist some instances when you want a really smooth finish and sand the primer. (never seen anyone do that unless there was something major issue underneath) Personally I prefer some texture, and I really use rollers that make a slightly textured finish.

mk_416 @108.168.55.x	mk_416 to TheSMJ Anon 2014-Aug-5 8:23 am to TheSMJ It really depends on the primer you are using and the finish of the paint. Eggshell and good primer, no need to clean it. Flat/pearl paint or not so dandy primer and a once over with a soft nylon broom is enough.

TheSMJ join:2009-08-nineteen Farmington, MI	TheSMJ to aurgathor Member 2014-Aug-five 8:24 am to aurgathor I'grand going for a flat finish on everything, so there would have to be a whole lot of texture for it to be noticeable. The primer I had applied is dry now, and I can't feel much of anything on information technology. I looked into trading my latex primer for PVA primer, and found that since I bought them during SW's twoscore% off auction, I paid less than $ten more than their PVA stuff. Even though the store is only a couple miles from my house, it doesn't seem to be worth the hassle getting information technology replaced.

From what I can gather it'south pointless unless yous need a super smoothen wall. The loftier solid content in PVA but absorbs the dust without whatever issues and works the aforementioned with or without dust on the drywall.
