So you're using greentop for finish coat and 45 hotmud for touchups?

 

Yup. After i have sanded. I dont really have much for touch ups. Dings , dents and flaws in the rock. Once I have sanded i expect to be getting a check and dont want my GCs to have any excuse to not pay me. Plus I dont plan on making an extra trip to come back and sand.

 

I have been using ez sand 45 for my touch ups. Its a different color then USG green top. For the rooms that are dark I just mark them with blue painters tape. I hate searching for them and I have a crew so theres no excuse for them not to see it. Small touch up small piece of tape. Large touch up bigger piece of tape.

 

don t use tint, just pencil em

 

Different batches of mud have different amounts of water, and therefore different densities. Could be you are touching up with a heavier/denser mix, than what you used for skimming. try touching up with the same mud. I seem to remember a discussion on this a while back. However, it was probably a thread that went off topic, so good luck finding it!

 

The problem is that I've got too many touch ups and the painters don't like that ^^[/QUOTE]

this is the problem right here. i'm not trying to be an ass but i don't usually have more than a few touch ups per room and they are usually so slight i know no one will see them. i've seen crews that must have thirty touch ups per room and bad ones too. you may as well just put a third coat on at that rate. when i do have to touch up i make sure not to skim the touch up tight for two reasons. firstly because you will compress the mud and make a harder area to sand on top of a uniform second coat thus the edges becoming worse not better. second, if the touch up has any depth to it, one skim will shrink too much and you will still see the defect.
my first effort would be to have less touch ups. one way or another more time needs to be taken to eliminate them.

 

Using a color additive or not touchups can be a pain if not done right. We do go through after finish sand for all ours. I've used never-miss, chalk, but usually use nothing. Verdicts still out for me about never-miss, some of my guys think it's easier to sand the touchups but I haven't really noticed a difference.

Thing is be sure to keep all edges pulled ass tight, and when you go to sand them have enough lighting to see if you killed the edge enough without "humping" the edges.

 

Never touched up nothing in all my taping days!!:blink:
After i leave a house its up 2 the painter 2 sort anything:thumbsup:

 

God I wish we had it like that :yes:.

 

I thought touch ups were a painters problem.

 

Come to Canada worky, our painters feel their above touch ups:furious:

combine these 4 pictures together, and that's what our painters think they are:yes:

 

Sounds like you are describing "onion skinning", the way I avoid it is spray the surrounding area with water first, that seems to soften or reactivate the existing topcoat, then when you touch up it's more like fresh over fresh so there should be no blending in problems when sanding.

 

Now that right there belongs in tips of the trade. :thumbsup:

 

What mud are you using?

 

touch up after prime.... problem solved :yes:

 

i see how this system works in your situation pointing up after your crews but i HATE touching up after prime. that's two more trips to any job than i ever plan on taking. mud does not go over primer as easy as fresh board. too many passes to eliminate fisheyes. thick, well mixed mud helps.

 

well, sounds like the tint your using is changing the texture of your mud, so try not to use too much tint.

I use blue chalk if needed (chalk line powder, don't use red), but even the chalk can cause the same problem. Trick is not to use too much. Make your mixture a very lite blue, not a very dark blue.

I'll try it again with even less tint then I guess. I've been waiting for primer since my last mess up like Thefinisher suggested

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!

Touch up and then sand!!!
