High Build Primer For Drywall New

plazaman

Just a very Crazy thought here, but do you think its possible to spray or roll a high build primer without even sanding new drywall? I want to skip the sanding step and go straight to the primer.


Again, i have no intentions of doing this, but just a crazy thought.

Ever heard of Equilizer? I have seen the dry wallers use it as a final coat. It like a mix between primer and mud. They use it for slick finishes.

Some of the guys out here mix mud with water to thin it out, then roll it on heavy and wet one wall at a time. Then a guy follows behind with an 18" blade and lays it down to a fast level five smooth finish. Still need a very slight sand but a great way to get an excellent finish fast...

We also spray a heavy coat of Hamiltons on new rock, backrolling to even it out which works pretty good at keeping sanding to a minimum.

Hamilton's? As in Hamilton's Prep Coat?

No way, High Build is not thick enough to cover un-sanded mud

Sorry- I misunderstood. I thought plazaman was talking about finished rock/mud- referring to the "fuzz" that occurs when priming new rock. We always sand first then patch/spot prime before painting. Guess that's what I thought he was referring to- not unsanded tape joints/mud- geez, no paint can cover that- even ter polymers.

Yes, I was referring to Hamiltons Prep Coat....

It is crazy, but...in real world applications, it does happen. Depends on how well the tapers smooth the walls. Usually, HB paint is used. The high build is just an extra. The main trick to this is to get the flattest paint with a color that just blobs everything, to the point that your eyes can't focus on imperfectons.

People who automatically feel the walls with their handswill find it right away.

Sucks on a repaint because the customer usually doesn't see anything wrong. You have to show them where unsanded mud has been painted over, and then fix it.

There is no way to get around sanding. Even 24 oz. commercial grade VWC won't hide unsanded drywall.

Exactly what color is it that "blobs everything together" to a point your eyes can't focus on it. Perhaps some multicolors might have that effect to a degree but no single color will.

First, I"ve never painted over unsanded drywall. The flat off whites without too much red, but black tints will do the blob trick.
