My patched areas, once primed and painted, are noticeably more "fragile" than original painted drywall - e.g. I can dent them with fingernails, the same way you can dent a chalk stick with fingernails.

(I’m not talking about a movement of the whole patch if i apply palm pressure — the patch is held firmly with screws in furring and/or studs. I’m talking about the repaired area not handling point pressure well. e.g. a ballpoint pen would leave a scratch rather than roll).

I’m wondering if that’s just par for the course with drywall repairs in general, or if there’s something I’m missing…

Here’s how i generally proceed to fix large holes:

  • add pieces of furring to provide a backing (or do california patch)

  • if any, prefill gaps with quickset joint compound (aka “hot mud”)

  • after it’s hardened, scrape excess bits (no sanding)

  • tape joints with lightweight all-purpose compound. let dry.

  • apply second coat to even out depressions or ridges, with lightweight all purpose. let dry

  • apply “skim coat” — very light coat, to feather out ridges, and remove bubbles, with lightweight all purpose. let dry.

  • sand until smooth to the touch. if there are pinholes, i will typically do local touchups (possibly that could be where i go wrong)

  • apply paint primer (specifically formulated for drywall) with a 10mm roller. let dry.

  • apply two coats of latex eggshell paint with 10mm roller. wait at least product recommended duration between coats.

  • give it 1 week to “cure”

After all this, i find the patched wall areas look good, but they are definitely “softer” than the other painted areas.

    If you mean dent vs the patch area having more give (which shouldn't be since you added the furring), I must ask what the original wall material is. If you have plaster like I do, that plaster top coat is really very hard. Drywall and mud don't have that, though the setting type muds are harder.

    Remember that drywall has stiff paper holding it together, the patch does not. If you remove the paper from drywall, your fingernail will dent the inside also.

  • i meant the dent having more give. the patch itself doesn’t move, relative to surrounding non-patched areas. i will update

  • following a flood restoration, where we had to cut off a 2 foot section at the bottom of the wall, we had to add a significant amount of joint compound to make the wall (imperceptibly) flat again and i was wondering if there was perhaps a remedy to the difference in hardness between repaired and non repaired. sounds like the best we can do is prime well and paint over it a few times, and then forget about it.

  • what do you mean with "softer", can you be more specific? texture? give/ movement? how much softer?
