Everyone has a good point, But ive found its just the mud, All purpose has glue, Its the glue level in the mud thats doing it, One nz made mud we have is a reall shocker for it, Dare touch that up bare and you have a problem, Other muds dont do it, The USG midweight being one. A lite mud thats topcoat only might work but i havent tryed it.

And go get one of those small plastic bottles 100ml or so with a cap and a drip hole, Take it to the paint shop and ask them to fill it with paint tinter of whatever colour you want, I use a deep yellow colour, Then you can tint your mud, It dosnt seem to affect sanding but i usually try and light check after priming and touch up then, If that cant be done then light check before sanding early in the morn on daylight when its darker, you see everything then.

Promix all purpose was a buggar for doing that, it didn't always behave like that though, I've stopped using it.


The problem with some muds is that when you apply a very thin touch up coat they tend to POLISH on, this polished coat is harder than the unpolished mud around it and under it. Villaboard finishing compound is the worst for it.

So is plus 4, Its really bad for onion skinning/layering etc, Thats what i use to use, Now im on the multi yellow bucket and im really happy with it, Holds corner tapes well, Nice through the tools, nice to pc or hand sand, Not to soft not to hard, It doesnt seem to onion skin and you can touch up with it, Really good all rounder and surprisingly doesnt bubble up much over paint.

What are you using now?? Im tradeset 90ing the beads and flats first coat though, Multi corners tape and top.

Sounds like your giving it good go anyway, Took me a while to figure out the zook, Now i just use it for corners as i want tradeset for taping and a homax does it well. I dont use a zook much but if i know im using it the next day then the night before i will spray it up with lanox, And up the tube then leave it head down in a empty paint pot over night, Next day shes good to go, If any mud get on it then it wont stick, Or just a hose off and its gone.
