Re: butt joints
Where are the roller marks? In the middle or at the bottom?

Re: butt joints
middle of butt, i put the second split coat on today and that seemed to work better, what do you mean by wider? the wheels are a little wider than the blade.

Re: butt joints
when you split dont let the two splits touch. I think you need to explain how you are finishing your butts for me to help.

Re: butt joints
When boxing butts,I hold the brake & keep the wheels lifted off the board about 1 inch for the full legth of the butt.

Re: butt joints
I first check my butts with a straight edge, like a metal stud or a 2x4. If they are really bad, I bust them out and don't even touch the tape. I spread out a 10" on both sides of the tape, wide, probably 2" off of the tape, so the tape is not even coated on the first coat. This helps flatten them. I also use some 2" screws if I need to and try and push the butts in more.

Re: butt joints
All the advice your getting here is right on the money!. I split with a 10. Down the middle with a 12. By then you can usually tell the real bad ones. bust out the bad by hand. There is no set way to do anything in this business. probably as many theorys on butts as there is members in this forum. Just keep experimenting and you will find what works best for you, good luck

Re: butt joints
Mesh vs paper, works alright on flats . I could never get it right in angles and the butts always seem to blister were the sheets come together. My solution was to stay away from the mesh completely, I don't like repairs. and besides that the mesh is alot more expensive.
as far as your problem with keeping the the wheel marks out of the middle of the butts, take miguel's advice. don't ride the wheels I never do ,it gives me more control and I get a lot cleaner job in the end |

Re: butt joints
AH this is where my tools excel! All the bad mouthing about blue line and I NEVER have this problem. Blue Line's wheels are on the inside of the blade path so this is not an issue for me!

Re: butt joints
I've done that, I found that it was less work to just not v them out and go wider. However, I do agree with you apple

Re: butt joints
but whitey when you v em you get rid of the loose paper on edge even if its a factory cut, after its prefilled its flush or better. Then the paper never creases out the way it does if you do nothing to the butt before taping. No call backs for cracked butt joints, other than garages but thats another thread. And for the guy with the straight edge if theyre that bad they were broke on the wrong truss or the hangers should float the butt w/ plywood.Your a drywaller not a plasterer, I plaster but usually dont go to that extreme, V em out first run split w/ 10 box wide open.Only way to go and i have never lost a client.
