Drywall finishing (taping the joints)
OK, basic dw question here
Taping the joints is simple and basic when it comes to two uncut edges which are tapered and abutted. However, in many cases, you have two CUT pieces where full-thickness edges come together. What is the best way to deal with these? Adding tape and mudding over could leave a "bulge" if nothing is done. Does one take a mallet and "ding in" the edges? Taper them somewhat with a knife? Also, any links to sites which tell how to deal with drywall finishing in this way would be helpful. |

"Cshenk" wrote in message ... I've done that. Got a power hand sander? We tapered the edges in. You do not want much, just enough to barely go through the paper and to the next level a tiney bit. Thanks! That's a good idea. I'd better get a fine belt; dw will get eaten up in no time with that sander. I do not know if my method is 'traditional'. It was something my Mom taught me when I was much younger. Makes for a nice finished wall. Your mom? Excellent! Usually it's the dad! You have a good mom there. Anyway, who cares about tradition. I just wanted something to work. Yours sounds like a good idea. |

Taping a butt joint, which is what you are talking about, is no big thing. Treat it like a standard joint, be sure to get the tape on with a very think coat under it, keep the next two coats very thin and feathered will out. The slight bulge will be unnoticeable unless you shine a light down the wall. If you ran your seams horizontally (the professional way) almost all your butt joints will fall above doors and above/below windows and thus practically invisible even under the worst conditions.

It is thicker than paper to start with and the coarse texture is hard to hide resulting in a bulge twice as high as with paper tape. Harry K |

"StarMan" wrote OK, basic dw question here Actually not so basic. Taping the joints is simple and basic when it comes to two uncut edges which are tapered and abutted. Yes. Note the taper is very small. However, in many cases, you have two CUT pieces where full-thickness edges come together. Knarly. Not fun but not that hard. What is the best way to deal with these?

Yes, I was worried about undermining the strength of the screws, not to mention the huge mess. Good to know about the paper tape!!!! As for the visibility, there are no seams which don't occur along windows. In fact that's why these 2 walls had to be made piecemeal; the windows are 3' wide, only 1' apart. The seams stem from the edges of the windows, except for one in the middle of a sg door (above it). I also had to DW up to a beam on one side. I'm still debating how best to deal with the beam; either to sand it smooth (it's rough), which is a lot of work, or get a finished piece of wood to cover it over. The DW is flush with it so I have opions. |

Also, any links to sites which tell how to deal with drywall finishing in this way would be helpful. Butt joints are simple...Remove any loose paper or broken drywall.Tape with paper tape just like tapered joints,let dry, then go down BOTH sides of the butt with a 12 inch trowl or knife,don't worry about the ridge of mud left in the middle yet.After it dries scrape/sand the ridge in the middle and coat down the middle with 12 inch trowl or knife.Let dry again.Now go down BOTH sides AGAIN with a 14 inch trowl or knife applying more pressure removing most of the mud..Sand as usual...Good luck..... |

I'd better get a fine belt; dw will get eaten up in no time with that sander. Yes, light duty with fine grain paper. Also it might help to know I was about 13yo then so not very strong. I didnt press hard. I do not know if my method is 'traditional'. It was something my Mom taught me when I was much younger. Makes for a nice finished wall. Your mom? Excellent! Usually it's the dad! You have a good mom there. Yeah, she's great. Dad skipped out when I was 2, youngest of 3. Mom had to find a way to make a living. Doing something close to the 'flipping houses' is how we made ends meet but we lived in them while we did it. As a result, I have an edge on most folks on home repairs, but that doesnt make me a professional. Just functional grin. Anyway, who cares about tradition. I just wanted something to work. Yours sounds like a good idea. If it helps, this one we learned by accident. My 15YO sister started at one end, I at the other, and when we met in the middle (bad tactic) we found we had to do this with cut ends. We hadnt measured it right (one of us was looking at the metric side, mea culpa). Chuckle, imagine 3 kids, age 13, 14, and 15 renovating a house with Mom to guide us. The finished product was very professional but the mistakes were pretty funny along the way. |

I'll add unless he seam is along a beam, you do not fasten it there. Unlikely he landed right on a beam there. with a very think coat under it, keep the next two coats very thin and feathered will out. The slight bulge will be unnoticeable unless you shine a light down the wall. If you ran your seams horizontally (the professional way) almost all your butt joints will fall above doors and above/below windows and thus practically invisible even under the worst conditions. Invisible both ways but you do not have to do horizontal (harder unless you have a team of people), just do it carefully and right if vertical seams. Most of the houses I see with the visible seams, are horizontal ones. |

Adding tape and mudding over could leave a "bulge" if nothing is done. You make the bulge less noticeable by creating a wide joint. Does one take a mallet and "ding in" the edges? Taper them somewhat with a knife? Nope. Drywall is very strong when it is in factory condition. It is very weak when you break the paper or mash the core. Also, any links to sites which tell how to deal with drywall finishing in this way would be helpful. Search for drywall butt joint finishing and you should find some helpful information. |

I'll add unless he seam is along a beam, you do not fasten it there. Unlikely he landed right on a beam there. 1. You don't want to let a butt joint float between studs without some sort of backer. 5" strips of chipboard or plywood work nicely. There are also products made for this purpose which will impart a slight bend in the ends of the boards to mimic a tapered edge. 2. Drywall needs the facing paper for strength. I would never recommend trying to create a tapered edge by removing the paper and part of the core. You could argue that taping the joint returns some of the strength, but that doesn't take into consideration that the fastener head ends up on the wrong side of the paper (tape). Fasteners should never tear or break the paper, much less be installed where there isn't any facing paper. |

Also, any links to sites which tell how to deal with drywall finishing in this way would be helpful. I never use joint compound. I just ducttape over the joints and start painting the walls. All that compound and stuff is too much work and only makes bulges. They used to sell prefinished woodgrain wallboard that didn't need any joint tape at all. Too bad they no longer sell it. Greg O |

If you can sand through the paper on drywall with a power sander (or even a hand sander) without creating a cloud of white dust, I want to see it. I suppose you could sand it outside but you would still have dust coming off it until you taped. Harry K |

Harry, lots of people didnt like my suggestion (didnt say I was a professional drywall type) but you do bring up a real one. Yes, a bit of dust. Dunno about you but my Mom never let us work with drywall without a mask. We also had wrap around ventfree goggles for much of the work. I dont recall wearing them that time, but probably my sister and i did. Mom didnt give us a choice on such things and we'd get in terrible trouble (grounded for a week!) if she caught us even once not wearing the right stuff for a job. As to weakening the drywall, I suppose it did a little but the finished product once taped and that compound you use over the tape then sanded out fine, made it look perfect. Don't think BTW that Mom was any slave driver of us kids. She was in there with us or working on some other part of the house while we'd be doing our part on the weekends/summers after all homework was done. When shed sell a house, she'd proudly show off just which parts were done by which kid. One thing we tried once and once only, then never again, was drywalling a ceiling. We just didnt have the arm power for the job among us. I was too little, and my brother is lightly built. My sister is very strong though and a hair under 6'. Mom and Charlotte got wore out trying to hold it in place while my brother tried to nail it up. Hilarous in retrospect. I'm sure there's a better way but we ended up contracting that part out and did drop ceiling panels ever after or brought someone in for that part if it was needed. We did the finish work (taping etc) ourselves though as we did a better job. See, with no set timescale, we took as much time as the job needed to get it *perfect* as possible. |

Sanding a taper in drywall butt ends for nice flat joints is perfectly practical if done outside or whatever. The argument about the the paper top layer giving it stength is a bit off the mark, because the real stength iis in the rock itself. The most important thing is attaching the butt ends to the framing (or support) with extra care. Probably the best technique is to simply use a constructioin adhesive. For a lot of years I have tapered with a handy 7" body grinder and used that same tool for truing up the frame member that the drywall attaches to. End result is a quickly done joint, very flat, little or no rework and no concerns about shadow lines from any lighting source. Works fine for me, YMMV. Joe |
