Steel spiral stair, spected for 3/4″ stone treads with 1″ mud bed. Any ideas on how to bond the mud bed to the steel? Concerned about vibration and cracking. Steel treads are 1/8″ plate, 1″ upturn to create pan for the mudbed. Welded to 3/4″ plate stringer. Pretty solid, but , still feel a little vibration at this stage. I assume that after the stone goes in, it will tighten up but I would like to be sure by ensureing the stone is bonded to the stair. Stonesetter hasn’t a clue at this point.

I'm no mason but I wouldn't.
If you can weld to them now (without ruining paint or setting the house on fire) then tack down some expanded metal. This will create a great mechanical bond. Otherwise, I suspect an epoxy based bonding agent could be used if such a thing exists. Call the local concrete plant/supplier and ask what's available.
They make a special bedding epoxy that I have tried out and one of the uses was attaching masonry to steel, The main use I got it for was glueing rebar dowels into an existing foundation, but the information on the cartrage gave that information, I got it at Boxley masonry products in Roanoke Va., it was a two part system that mixed itself in the tube when you dispenced it as far as I know 15yrs later it's still holding and I also used it for a slate repair job on some steps once since I had a couple of tubes left around the same time.
I wonder if that was a Hilti product that you used? I have used their "hit" system that mixes the 2 parts in a spiral tube. I'll give them a call and see if they have anything. Thanks
I will call down there here in a little bit and see what it is called and get back in touch.
I don't want to be a pain, but, what the heck, while you got them on the phone, ask if their product can be squirted ( I think that's the correct technical term ) on a steel pan and a concrete product put on top,... right away? ... after it sets? What do they think? Also, I don't think I mentioned that these are interior stairs. I 'll check the budget and see if I can get you a consulting fee. (Note: that last statement was a lie )
Karp--just checked with my main masonry dist.-dont have it any more but it was by powers co.--but I tracked down what you need to use though--I called the tech line at powers and they said because of the deflection in the treads THEY would recommend a poly urathane type product well any way called up my construction materials house -A.H. Harris & sons, Va. const. supply - they recommened Sikaflex11F.C. adhesive then I called sika's tech line and they recommened the same thing sikaflex 11 F.C. with a wire brushed down to bare metal and a primer coat of sikaflex 260 primer I have used the same stuff repairing slate steps. and repairing masonry exp. joints that primer makes all the difference in the world on making poly caulk or adhesive adhear to whatever you are using it on. The tech line # for Sika is !-800-933-7452- what area are you in? need to fill out your profile. Glad to help DW
I know that euclid chemical co. makes a primer that you use on clean steel and you can mortar or pour concrete onto it and it will stick to beat the band ive use it on a stainless well cover that I layed bricks on. The family owned a large industrial supply co. and wanted this handdug well made into a table so rebricked the well top and layed a industial sprocket I fabrcated out of stone and brick into the table top , looked cool.
Wow,... thanks, that's a lot of info. That product is available here, (toronto, Ont. ) As for my profile, how do I update it? I didn't even know there was one. Oh, and I hope I'm not being to personal but are you at home in your underwear? where do you find time to chase all that down? I barely have time to read this thread. I'm in a trailer on site, so I get about 10 min. before some clown,... I mean, highly skilled craftsman, bangs on the door with the next problem. Breaktime really is a break for me because there all someone ELSES problems. Its nice to help and not have to sign-off on a problem. My stairs for example, Architect, "Idon'tknow" Engineer, "Idon'tknow" Tilesetter, "Idon'tknow" So I'll make a proposal, and get one of them to "sign-off" . I hope. Damn, there's the door.
no underwear here.I just have done a lot of different things, but what I am doing right now is by far the most challenging thing I have done in my whole life, I sweated worked two jobs, raised my two oldest younguns by myself got them through collage,found me a good woman the second time around, now I have a 14 yr.old step son and a two yr.old and a four yr. old that are mine. I do masonry jobs in my spare time, as I am a stay at home dad full time,My wife has more consonants in front of and behind her name than most peoples full name , so she earns the living &I take care of the younguns and her needs :) I do mostly repair and custom stuff, so I get into a lot of different jobs ,hence I a least knew where to get the information you needed.I admire the craftsmen and women in this forum they implement things I can only think about ,with wood anyway. I also am a firm believer in that you can think something to death, as a old swede told me one time ,talking about a obsessively detail oriented co worker -{he dresses up in a white tuxedo, then craps himself}sometimes you have to use what information you have and just run with it, worry about the small stuff later.
Well, my hat's off to you, because, according to my calculations, you've got,... just a sec,...carry the 1,... 5 kids! wow! My wife and I had problems trying to concieve and that lead us to eventually adopt. So, 2 months ago, we got a 2 yr. old boy. Just the one child and my life has turned topsy-turvy. I'm still trying to get use to it. I love the fact that your at home. If it wasn't for the whole MONEY thing, that's where I'd love to be. My wife is at home, so that's a blessing, but she will be going back to work in the fall. So I guess I've got a few months to win the lottery.
I'll let you know how I make out on the stairs.
