What's wrong with my touch ups?

Hey guys! Got a problem here

For some reason I've been having lots of trouble with my touch ups after my final sanding. I mix my mud with professional tint from the supplier. The problem is that when I sand the touch ups, my sponge doesn't sand the tinted mud but it sands the skim coat around it... leaving a bigger touch up...

I was working with another taper who was using the same tint and he had no problem. So it's not the tint. I've tried using thin and thick mub but it makes no difference. I've also tried using less tint but I still got this problem :S

Anybody knows what I could be doing wrong?

Thanks!

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.

Stopper, if your mud is drying up that hard on the chain, you need to let it sit in a bucket of water when you aren't running. Keeps all that mud wet. We tape all flats, take a break, the taper head is soaking at this time. When we start angles, the head gets scrubbed. A crummy head while running angles will cause you grief. If it gets crusty while running angles we'll scrub it again.

To be honest I wasn't paying much attention to the chain when I was using it, it wasn't till after I got home and watched a few of 2Bucks videos and saw him mention "not getting mud on the chain" that I thought that that might be my problem. I rule the tube out as the plunger was sliding nice and free, I kept a wet rag stuffed in the end of the zooka to keep it moist.

t if i know im using it the next day then the night before i will spray it up with lanox, .
Thanks I'll try that. :thumbup: I've ordered some St Johns Wort too :D

after your skim coat sets up, depending on climate/temp go through and touch it up when its stick tacky, on any finish we always go through and spot all the corner bead, butts, angles and seems like a screw, basically crossing anything off and just pull everything tight, like a screw as stated before. This eliminates pinholes and dust filled gouges you might not see otherwise. I use tint also in my mud, not never miss but a different product we came up with ourself, not chalk or anything like that, and I can use red color to tape, skim, touchups texture, whichever step its is and it does NOT bleed through the primer. Chalk has a tendency to change the porosity of the mud and can cause problems later on, so stay away from that, and I don't use the tint to find touchups, I mix it in every box of mud I apply, because its brightens the day ! :D

I never said anything about chalk coming through,but I've seen it happen myself, maybe the guilty party used an excessive amount, but it has null advantages when adding it to drywall mud besides leaving something behind for different materials NOT to bond well with. How much testing have you done with chalkline and the different aspects of mud, primer, paints, lacquers, acrylics, latex's oil bases?

I recently use the Dewalt blue chalk. It is bolder/ darker than Ervin chalk. I have always used blue and never had any problems with bleeding through.

I used to have this same problem. Touch ups not sanding out no matter how tight I feathered them. Then I realized it was actually worse the tighter I put it on. Thats when it dawned on me to try leaving the edges a little heavier.. and voila my touch ups sand out perfectly now. It seems contrary to logic but it works
