project: filling in garbage knock down texture with semi(?) gloss paint. Pre-70’s home so Lead paint and asbestos is possible.

I’ve been getting some nasty scratches lately in my joint compound applications

I scrape the wall getting anything that sticks out.
Primer (it does it with Kilz 2 and Zinsser 1-2-3)
Joint compound (all purpose usg green)
Topping (usg light blue)


before it would be a simple speck here or there in the joint compound itself etc. But now it’s taking the primer off too. I bought a new taping knife and it still did the same thing. The first two rooms I worked on didn’t have this issue.

has anyone come across this issue before?

Kilz Pva, then re skim

Kilz Pva, then re skim

Will that work on already painted walls? Especially when the coat I’m priming over is semi-gloss and low quality?

Prpbably not in that situation, id just skim over it, prime with pva and see if that works.

First, scrape the area clean and level using the putty knife. Next, apply a small amount of the spackling compound to cover the scratch with a putty knife and a small area around the scratch.

Mjaw is absolutely right. I’d would like to add only one thing. It’s good practice to sand paint before doing anything to it. Even between coats. I think that may be why it’s so rough. No one does that and tiny bumps grow into larger ones.

you really got some boogers in your mud there! lol

look up "roll skimming'. its a more light handed way of skimming walls. easier on the arms too roll mud on like a good coat of paint then knife it down slick. if you did a good job, sand lightly and repeat as needed. you can walk through and touch your bad spots if you leave a lot of lap marks and edges on first coat.
