#Drywall skim coat intentionally leave blemishes how to

You can stop at this level if you intend to cover the wall surface with tile, or if it's in a garage intended to be used for storage or a workshop-type space. Level 2 : This next level means that you have skimmed a thin coat of joint compound over the tape and covered the drywall screw holes.Level 1 : This level means that drywall joint tape has been embedded in joint compound, but nothing further has been done.At this level, drywall is simply fastened to the walls or ceiling. Level 0 : Level 0 implies that no finishing of any type has been done.The Spruce Home Improvement Review Board.This needs to be done by end of day today. I can sand t and prime this evening.Īny other suggestions…I am running out of time. I may just buy a broad knife and do a very thin skim to just fill in the grooves and rough areas, with regular pre-mix joint compound. He felt that skimming over the smooth primer could fail/peel off over time. He advised against skimming over the primer without Plaster Weld and roughing up the wall a bit. Stripping the entire 170 sq/ft of this primer would be an epic nigthmare. The problem is the Behr will not sand it will roll up when sanded. He advised sanding the primer off and then sanding the marks out of the underlying skim coat. THe other primers will not fill the sanding marks he said. He considered every option and doesn’t have a product that can be rolled on. They have a high build surfacer product but it is only sprayable. This is turning into a bit of a nightmare. I’m thinking a couple coats of a sandable high build primer might do the job.

I’m time pressured on this room, so I do not think I have the time to do a skim over the whole wall I did a light skim to some of the worst areas, but there’s more areas that need to be smoothed out. The screening marks are not super deep, but they are there. I also have a gallon of Zinsser ZERO primer here and a gallon of Zinsser 123. I bought Ben Moore Fresh Start acrylic and it was much more pleasant to apply and covers better. Never again…the remaining 5 gallon bucket of Behr Primer is repurposed as a stool.įor the room in question, I primed the ceiling. But, I did get a good primed finish in the hallway, I was very deliberate in applying it, it’s not a very forgiving product. They left me with 5 gallons of the Behr and I did a hallway with it. Yeah, the walls in that room were done with Behr primer. The walls are 80 year old plaster although the skim coat is joint compound with some plaster of Paris mixed in.

Topcoat will be 2 coats of Ben Moore Regal flat or matte.Īny ideas on how to do this? Quick and dirty? Again, I just need a really thin layer of something to fill the scratches, then sand it back to smooth. But I have the feeling it will end up being too much work and I need to get this room wrapped up ASAP. The other thought was I’ve read of the technique of using a roller to apply thinned joint compound to get the skim coat. Working within my tool and time constraints, I was wondering if there’s some sort of high build sandable filler or primer I could roll on (no sprayer), maybe apply a couple coats to fill in the screening marks, then sand it smooth. Had the same issue on another smaller wall in this room and I used ready mix all purpose joint compound with a taping knife and put a very thin skim coat.īut I really do not have time to re-skimcoat this wall, it’s 18’ long. Btw, these are plaster on wood lathe walls. The primer they used was Behr #73, New Drywall Primer/sealer. Mind you, they are not DEEP, just surface screening marks on a wall that was incorrectly or incompletely sanded. The screening marks are just sloppy work and I’d like to get a smooth surface. The undulations I can live with and consider it ‘character’. My dining room was skim coated by workers form the building management.Ī couple of the walls were not done so well…there’s some undulation in the walls, but more annoying on a couple walls there's sanding screen marks through the primer…obviously it wasn’t sanded well (other rooms walls were sanded to 220 with sandpaper).
