Sanding/Feathering on Drywall with Knockdown Texture
I'm painting our bedroom wall. Before we paint, I've also just fixed a giant hole in the drywall: cut out a 1'x16" rectangular section and replaced with new drywall piece.
I've mesh/fiberglass taped and applied a fresh layer of joint compound and wet-sanded a bit. Now, I'm starting to sand and my previous experience (twice before) has me worrying about blending into the existing knock-down texture.
For walls with KD texture, is it OK to have less feathering on edges since I have to replace all the KD anyway? ie. going for "smooth as glass feathering" isn't needed? If I apply a wider Skim layer, the additional compound annoyingly fills gaps in existing KD (making it all flat) and then there is more to sand, further outside of the repaired area.
I've done moderate sanding to avoid a straight visible seam, just trying to avoid spreading the compound out even further, ruining more of the existing texture.
Does this logic translate into a decent real world repair?
