Any magic for fixing persistent cracks?

I went to see 30 foot wide ceiling today that had a perfectly straight crack right down the middle of it (directly under the center of the roof trusses). It's almost like 2 cracks where the paper has twisted over an unfilled 1/4" gap in the boarding behind the tape (but in the case from what I saw digging, there was no gap). It was originally taped by one of the best crews in our area, then failed, then paper taped again (originally it would have been a tapered seam, then it was retaped like a butt seam--likely V'd out first from what I saw digging around with a utility knife). The second time it was taped, apparently it failed by the time it was painted just a few weeks later. the paper hasn't torn, it's just cracked the mud in a 3/16" strip down the middle of the tape.

The crew who originally taped it no longer works for my GC, so now its my baby. If it didn't work twice for the previous, very well respected crew, I'm not real excited about using regular taping mud and paper tape in the same manner as the other two applications. The owner won't accept the look of the trim-tex magic corner joint down the center of the room (flat ceiling rather than a vault). I can't imagine no coat being used in a flat application.

Does anyone have any magic tricks for a crack like this? I'm considering rasping out the second layer of tape and redoing it using vario and fibafuse (pending the outcome of some experimentation in my shop), but would sure appreciate any suggestions you guys might have from past experiences.

Thanks,

Steve

Just like 2buckcanuck said; "Rockers did not put a backer/wood/steel stud behind the joint, it would crack again no matter what I did." I've had numerous crack problems from customers; meandering wall and ceiling cracks, but I recently came across a newly patented perforated steel backing plate that can be inserted directly through the crack at 4 inch intervals, where it can be held in place against the backside of the cracked wall, then fastened from the outside with drywall screws; it makes for a smooth surface for refinishing and installs in seconds with a reusable hand tool. You should first cut a 1/4" groove along the crack, then cut 1/4" X 1 1/" slots every 4 inches between studs. I use mesh tape and 20 minute easy sand. They market under the name Insisi-Back, from Prest-On Drywall Fasteners. Check it out in the USPTO patent database (US 8,024,903B2). I'll bet it solves your crack problems. It works great for me.

New Product-Steel Backing Plates repair cracks. New Patent issued 9-2011

Yes-Indeed! I do know a "Magic Trick" to fix drywall cracks. Your best solution is finally here. This reply represents a Press Release about a New Product, announced by "CRACKMAN." I am the inventor of a new technology drywall crack repair Backing Plate, awarded U.S. Patent US8,024,903B2 September 27, 2011; under the title, "Drywall Crack Repair Backing Plate," registered under the Trade Name, Invisi-Back(R). Why Invisi-Back(R)? For over 90 Years; the drywall industry has known only 3 ways to repair drywall cracks;
1) Tape & Float; like putting a Band-Aid on a deep cut, it only covers the surface with paper tape and drywall compound. The cracks usually return.
2) The Patch-Over; about the same, but somewhat stronger.
3) The Replacement Method; replacing all affected wallboard panels. It is the most expensive method of all. It is environmentally unsafe, usually forcing the homeowner to vacate during re-construction; and it is a clean-up nightmare!

Now; for the first time in 90 years
of drywall crack problems, there is a real solution to this ugly problem. Invisi-Back is a simple to use two part metallic device that includes a palm-sized reinforced, perforated steel plate; Invisi-Back(R), can be installed with the use of its Re-Usable "Applicator Tool." The two parts, when assembled, create a living hinged device, which can be easily and quickly inserted directly into pre-cut slits in the crack, (like using a jackknife) at 3-4 inch intervals between the studs or ceiling joists. Once the trailing edge of Invisi-Back passes the inner wallboard surface, it will automatically spring open within the blind-side of the wall cavity. Pulling out on the Finger Loop of the Applicator Tool forces the Invisi-Back to lie flat on the inner panel surface; where it is held in place with the finger of one hand, while blindly driving 1" drywall screws at 3/4" from the crack on both sides of the cracked panel edges with the other hand, and into the perforations; installed from within the room with the cracks. The Applicator Tool can be released from the Invisi-Back with a slight squeeze of the hand, whereby it may be re-used for installing multiples along the crack. Invisi-Back creates structurally strong artificial backing, without attachment or support from nearby studs or joists, and can be installed at any location along the wall or ceiling. The end result is the smoothest possible surface for refinishing the repair; without any bumps, crowns and ridges. The device is user-friendly, simple to use, cost effective, without having to replace any drywall panels. Clean-up after the project is a snap, with very little inconvenience to the homeowner. Repairs in one room can usually be accomplished in two days. A prototype of Invisi-Back was field tested by the inventor in San Antonio, Texas for 4 years, with great success and without cracks coming back in the same place.

After making the final repair; Tape & Float, re-texture and paint as normal. Contrary to what most people think; Tape & Float is NOT-TRUE-CRACK-REPAIR. It's what you do after the crack repair, provided you know how to truly make the repair. Invisi-Back(R) provides the "know-how." And it will surely be; "CHANGING THE WAY YOU THINK ABOUT DRYWALL CRACK REPAIR(SM)." Invisi-Back(R) is presently being manufactured and distributed by Prest-On Drywall Fasteners, in Hot Springs Arkansas, and should soon be available at Lowe's, Home Depot and many Contractor Supply houses. Invisi-Back may now be purchased in single packs of 6, plus one Applicator Tool, and 12 drywall screws. Or it may be purchased in bulk of 200 each case.

If they want a flat ceiling and not an expansion joint, and they can't back block it where it is, then you might have to "shift" the joint by cutting a wide section out of the ceiling and making two joins, one each side,(so you have no join where the original crack was), that can be back blocked with more drywall making them strong..ofcourse the ceiling might just as easily crack somewhere else.

Steve; you need to try something new that has Tape & Float beat; hands down. The newly patented Invisi-Back; creates an artificial backing without attachment to nearby studs or joists. It's made of re-enforced perforated steel, that can be installed in multiples by inserting it directly into the crack within the blind-side, where it can be fastened with drywall screws from inside the room. The U.S. patent #8,024,903 B2 was just issued on September 27, 2011; presently being manufactured and sold by Prest-On Drywall Fasteners at Email (orders@prest-on.com) or by phone at (800) 323-1813. See the photos in my post of today #39.

Drifter - While you may have a decent product there for small patch jobs it sounds like the problem is a 30 foot long crack. Using your product for such a big crack in my opinion would be a major pain in the ass and regardless it would not work if the seam is up against existing backing already. If you want to push your product why not use the Reviews function?
 
#51 ·
I just take a piece of shiny 90, work it into the crack, screw it, then work another piece in on the other side, screw them together and cut off the overhanging part with a grinder. Unfortunately, every time I do this, the part where I screwed them together falls off onto the floor. Then the joint cracks again. It sucks.

Man, business sure is slow lately.:blink:

Actually, my magic for fixing persistent cracks is to pull my pants up and tighten my belt.

Reply to mudshark

OOPS! On 6/10 I wrote this reply to “KiwiMan” in error, when it should have been directed to you, Mister “Mudshark”; in response to the negative remarks about the new Invisi-Back®. See my response, with a few added thoughts below;

OK: Kiwiman is right-on when he says Invisi-Back won't work if it is a (30 ft whatever) butt joint that is already backed along the seam. I must have not correctly read the post. However; this new product is not just for small "patch jobs' because it is not just a patch. Meandering cracks can run horizontal across wall studs or ceiling joists, then vertical between them. Such a crack can run very long without backing. It seems to me that it would be a far greater frustration ("pain-in-the ass") when you already know, from your past expert experience, that to merely Tape & Float; or Patch over persistent cracks has always miserably failed, because it does nothing to strengthen and reconstruct the crack from under the surface; like putting a Band-Aid on a deep cut; that kind of "fix" has been the industry-wide-"standard frustration" for over 90 years. Sure; you could go the radical route, by replacing all the crack affected wallboard panels? That's a frustrating job too; it's costly, hazardous to the environment, a great inconvenience to the homeowner; and it’s a clean-up nightmare!

And, just so you know, I’m not just another pretty-faced salesman in a pin-striped suit, trying to peddle his wares. I did all this stuff for a living for 15 years, as a Licensed Drywall Contractor; just like you. Yep! I am interested in pushing this new product, because I know first-hand that this damned thing works; and it does all that it’s cracked-up to be! Pardon the word game. I too was frustrated because I knew there had to be a better and less costly way to fix persistent drywall cracks for my customers. The idea for this steel backing plate product came to me out of that necessity. I tried a number of backing designs before I came upon the best, fabricated a whole bunch of the best prototype plates in my garage; then I field-tested it for four years before my patent was finally issued last September. The biggest marketing challenge is to find the key that will open the minds of the industry to accept a new or improved idea. So guys; why not try another way, before you start knocking it? Tape & Float is what you do after you really “fix” the crack, with Invisi-Back®. Try this method, and you will soon be "Changing the Way you think about drywall crack repair."

A) Treat the broken panel edges like butt-seams by fastening the edges to the studs to draw the both panels flush.
B) Install re-enforced steel backing plates, (Invisi-Back) strategically placed about 3-4 Inches apart along the crack between studs or joists. Place a final Invisi-Back at the termination point to stem the crack's travel; like the Liberty Bell fix. The end result is a structurally strong repair that reconstructs broken wallboard panels; and it provides the smoothest possible surface for re-finishing, that is free of bumps, ridges and crowns.
C) Tape & Float after the true repair, for final bonding and smoothing; followed by match texture and painting.

I have attached a few photographs from my project gallery for you to see the before and after results; along with a quick lesson on how to use it. Invisi-Back® is presently being manufactured and marketed by Prest-On Drywall Fasteners, Tel: (800) 323-1813; or www.orders@prest-onj.com. Now; if Kiwiman, or anyone else wants a free sample of Invisi-Back, please Email your mailing address to me and I will send a "Six-Pack" free of charge. That way you guys can write your own New Product Review. Of course, I will gladly respond to any questions about special product use issues, so do let me know how I can be of help.

Mudsharks not knocking your product, he's just addressing the issue/problem of the thread. What he's trying to say is.....

Start your own thread, that deals specifically with your product. State what it does. (which you have done). Then, like a lot of other manufacturers have done, offer some samples to the first 10 or 20 dwt members that PM you, or what ever number you like, to test your product. Be nice, and don't forget to ask the mods for their permission.

Bottom line you half to put something on the line. If all goes good, people will fill your thread with good HONEST opinions, and maybe even write a review, but on the other hand:whistling2:

Some guys come on here pushing their wares, then begin to fight with Drywall talk members. So you half to be serious,,,, and nice,,, or the mods will ban you:yes:

The biggest challenge to trying a new product to fix cracks is this (at least in my niche):

I can't afford to have to go back and fix something again if the new product fails to do the trick. Usually, people are living/working in the unit.......which means I have a lot of protection to do. When I leave, the crack is fixed......because, if it's a framing issue, it has been addressed. And, if it's a drywall problem, well, I just happen to know a guy who can fix that stuff. Sans bandaids.

Thanks a million for making me aware of my bein' a jerk when I got myself all riled-up and my feathers ruffled at your seeming negative remarks about my Invisi-Back product, Mister Mudshark, Sir. Although I'm Not trying to excuse my poor response to your comments; please do understand my motivation for coming a bit un-glued.... I worked on getting the patent for this product for five years, went through many sleepless nights writing and re-writing legal language and re-drafting the mechanical drawings six times, in my struggles with the USPTO. Besides all, that, I was successful in making a good living by using a prototype of the device during all that time; having proved that it does indeed provide the only true drywall crack repair, without the cracks coming back in the same place. So please do accept my sincere apology to you and to anyone else who read my inappropriate response. I do promise to be less sensitive in the future, and I will surely "be nice and serious." I do value the opportunity to be a member of this forum. I also want to thank Mr. 2buckcanuck for his recommendation for me to start my own thread about this new product; perhaps I will start a BLOG, if I can figure out how to do that. I do have a number of good tips and ideas about generating business doing drywall crack repair as a specialty service business, as well as special application advice. Of course I do welcome questions about certain application situations when using Invisi-Back. Slim Pickens said that a new product he uses has to do the trick the first time, because he can't afford to go back and fix something again. He is so right. That is the great benefit of Invisi-Back. It DOES fix it the first time; unlike most tape and float, or other methods. I have CAZNA's address and have sent him a "Six-Pack." Mister Mudshark, please send me your mailing address, so I can send you a "Six-Pack" of Invisi-Back to you too. Try it yourself. And, sincerely man.. Thanks a bunch. Drifter.

Hi Drifter. Although I haven't commented much on this thread at all, I would be interested in trying your patches.
Maybe even put together a promotional video for your company if you don't already have one.
Do you already have a distributor?
PM me and we can try to work something out.

RE: Invisi-Back-Response to Precision Taping.

I'm glad get the good words from you. Don't know anything but your "stage-name", but mine is Robert Riggs and my "Drifter' stage name is from my pride and joy, a 12 year old Thoroughbred Ex-Race Horse, (Jockey club registry name: Cowboy Drifter 4th generation out of the famed; Secretariat, and kin to both Native Dancer and Man-O-War. Here are my answers;
#1. If I can get your mailing address I will send a "Six-Pack" of them to try them out.
#2. I am very interested in doing a Promo-Video and I would be honored to help put it together with you. I do appreciate the offer. What better way of getting such a presentation put together than to go to the one who invented the product and personally field-tested its prototype in actual business for four years? As a side note of interest to you; Before I decided to retire and act on my life-long desire to go into business as a Pro-Handyman & Home Repair Contractor in 1995; I was a traveling Law-Book Salesman and Territory Manager for a large Legal Publisher or 20 years, in which I regularly made presentations of both our printed and computer generated publications to customers and prospects. A great part of my duties included, co-authoring our company sales training manual and video training program, personally training sales representatives in selling techniques and marketing, teaching a college credit course in how to conduct legal research to large groups of law school students. For fun; I was also a lead performer in a small theater group for seven years in St. Louis, where I then lived.
#3. Presently, I do have an Exclusive Licensing Agreement with Prest-On Drywall Fasteners (www.prest-on.com), in Hot Springs, Arkansas. They are now manufacturing, marketing and distributing the Invisi-Back; along with their own drywall fastening product line. The latest news I have is that Prest-On has made great inroads with the Home Depot, which will soon have Invisi-Back displayed on their shelves everywhere. Home Depot has announced that they will produce a training video, which is now in progress. I don't know what that will look like when it goes live on their website, because I have not yet been asked for any input as to its content. Therefore; I do have my doubts as to how good that will be. The good word is spreading since my patent was issued last September but it is a slow moving process getting making the market aware of the product, and to accept the possibility that there just might be a more effective way to fix wallboard cracks. We need to get Invisi-Back in the hands of the pros in our market.
#4. Another great benefit to using Invisi-Back is that; after they are installed behind the wall with the crack, there is nothing left on the outer surface that would foul-up automatic taping equipment; no sharp metal edges. The result is the smoothest possible surface for re-finishing. Thumbs up on that one too! :thumbup:

Hats Off Mister Mudshark; Thanks for the encouragement. I'm trying to figure out how to start a new thread about my Invisi-Back Drywall crack repair backing plate; covering tips and special ideas and advice in its usage, including ways to generate business using the product. Can you, or anyone give me some pointers as to how to start a thread like that; or perhaps it should be done in a blog? I'm really new at using this forum. Thanks in advance. Drifter.

Go to Forum

Then I suggest clicking on "drywall tools,supplies and equipment"

Then you will see new topic.

DWT still needs fixing, so allow the 1st post to screw up, it will do stuff like........^^^^--4 PT has a small stick (((%#@

Just insert 4 happy faces or something,,,, like this:D:D:D:D

Invisi-Back® Drywall Creack Repair Backing Plates. Q & A Department:
Question from Tucker:

Answer: Yeah Boy! You are right about many homes being built with foam in the wall cavities. That’s a really bad idea, because it causes big trouble when repairs need to be done, like when an AC Technician, Electrician, Plumber, or any other pro needs to cut into the wall, for many reasons. Here is a “Good Indian Trick” for making drywall crack repairs in walls that have been foamed. Mobile home manufacturers really go nuts with foam in the walls; and in the ceiling as well. The product “Great Stuff®” is habitually used by most of them. I have been called upon to fix some of those cracks. Try this good, but tough little trick;

#1. First; cut a shallow bedding V groove along the crack, using a utility knife.
#2. Make a 1/8 wide cut into the crack along its path.
#3.
Wedge-Cut out a small rectangular wallboard section; the same size as one invisi-Back, (1 1/2" X 3") across the crack, with the long side diagonal to the crack. Be sure to cut that little piece concave at the edges so you can use it again to plug up the hole you cut. Do save that little piece for later.
#4.
Now look to see if you have ample separation between the foam and inner side of the wallboard, to slide Invisi-Back between that gap.
#5. If there is at least a 1/4" thin gap; load one Invisi-Back onto the Applicator Tool, and place it into the hole against the foam.
#6. Now slide the assembled Invisi-Back over to the left or right side along that crack until it is positioned under the cracked panel where you want it.
#7. Now "blind" fasten the Invisi-Back through each side of the panel edge, and release the Applicator Tool, to be used again.
#8
. After the completed repair; butter the edges of that little cut-out piece and use it to plug up the hole. Follow that with standard taping.
VIP NOTES:
If you need to install more than one Invisi-Back; use the same procedure as in 4 through 7, starting from the farthest placement. This is the tricky part. If there is not adequate space between the foam and the board; you will have to heat that steel plate Invisi-Back first, with a good hair dryer or a butane torch so it will melt enough foam to get the thing to slide over into position; being really quick about it too.... I should not have to tell you not to stupidly let open flame touch that foam or any other flamable material. DUHHHH! Don't be stupid. I have pasted in a rough drawing of how this can be done. Now; if you will send me your mailing address by Email, I will send over a "Six-Pack" of Invisi-Back to try it out. Best regards, Drifter. drifter2739@yahoo.com

In response to the plywood idea...
sounds like a reasonable solution. you could add 2x2's also that are screwed to truss at each end of ply and again through the drywall from underside and through the 2x2 as well. In effect creating the bracing that it needs. then I would, as previously suggested, use fiberglass mesh, then bed papertape over that WITH durabond, then treat as a butt joint. Durabond for the bed coat. make sure you are at top of your game on this "butt" because as you mentioned, it is built up. Nice and wide, maybe a fourth skim even, so no one notices. everyone will be staring at this point. I have had success at fixing cracks in plaster using this taping method with the mesh, hot mud, paper, hot mud with no call backs so far. have also done it with drywall. Hope this helps.............

Is that you Mister Mudshark; the mean face givin' the bird? OK; No Problemo! I can take a good Jab once in a while. Tell me though; is that your number of years in school, or your IQ???
No that's not Mudshark...That is SIR Mudslingr...Your talking about IQs ,,but cant start a thread..If my jethro ass can start a thread or edit my profile than i'm sure the guy that can fix the unfixable crack can!:rolleyes:
