Is the lime putty kiln dried first? I have a large quantity of limestone slurry from my stone veneer if facility and I am considering turning it into mortar to sell as product.
What's the difference from using lime mortar vs using a NHL 3.5 Lime (or similar) in terms of Practical use. It's so hard to find NHL here in the midwest so I was wondering if they're interchangeable. Thanks in advance for any advice or thoughts.
Andrew Weis the NHL mortar is a hydraulic mortar, part 1 of my series on mortar talks about this some more but basically the difference is in the water resistance of the mortar, hydraulic lime will set in moist locations and regular lime mortar may not. How old is the brick you are working with?
1880 the home was built using a 2 1/2 inch thick foundsation wall which seems to be mostly comprised of limestone blocks. I live in Eastern Iowa where temps can get into the -10 to -20 ranges. It's descent on the inside mostly but there was a section where there was a small river flowing throught the foundation over a crawlspace into my lower basement which drains into the city main.. The water itself was easy to deal with but the eroded hole in the foundation wasnt . I dug away a small section of the dirt on that side of the home to find that most of the mortor that was basically eroded away and was replaced with dirt that was inbetween a good chunk of the rocks. The foundation basically fell apart in that small section. I temporarly and lightly used a portland based mix i happen to have sitting around to put a fair portion of the very deep rocks back into the wall which is about 2 1/2 feet just to put a bandaid on the deterization, but I went light on the mortar as I know its' not friendly with old stones. Any how now I'm here trying to make the best descisions I can to move forward with the repair. FYI. I do plan on installing an updated rain water drain system on the trouble areas of the house. I believe there was a sort of dry well/french drain setup only there was no drainaige tube of any sort in the ground just what looked like a foot or so of loose gravel athat wasnt wrapped in any soil membrane and was completely impacted with dirt. So ya, that's on the list too, let the fun begin :)
Andrew Weis you will probably be fine using the NHL mortar, as you probably know the reason to use lime mortar is that the way that bricks were made left them with a hard shell and a softer center that can be exposed if the mortar is harder than the brick. In your case you have limestone which should be the same density throughout. NHL mortar should still be softer than a Portland cement mortar and will resist any moisture that may appear later on.
Yea, the real issue come froms the moisture working it's way into/out of the walls. Where I believe NHL will allow that process to happen naturally and in a way "flex" with any movement. The next thing I have to ask is if you may know of anywhere in my area that may sell this type of lime. I've checked the box stores like Menards, Lowes, Home depot.. and they dont seem to stock it or even really have a clue about it. I guess I'll just move up the chain onto the more specific vendors of the trade and see what I can find hopefully without paying an overly high price or traveling. I figured I'd ask anyhow and maybe get lucky.
Should've used Hydrated Lime! Also, just filling in the crack will actually make things worse over time. You need to chisel out all soft mortar just past half of the brick and then fill it in once washed and brushed. What you're doing is only covering up the problem instead of fixing the problem.
so, does the lime putty have any practical use outside of being an ingredient for mortar? Will it dry if used purely as a plaster? Can I shape lime putty into blocks ?
Hi, to the best of my knowlage Yes lime putty will dry without adding the sand if you wanted to make it into a block however I think that it would be very weak and would crack easily. this is just a guess on my part as I have not tried it. As for plaster you can make a traditional mortar in basicly the same way as the mortar just using a different ratio of sand and lime. do you have a project in mind that you could give more details on?
Estate Groundskeeper Hi. Really appreciate you replying. No, I don't have a project in mind. I'm just fascinated by the potential of lime plasters and currently developing my knowledge
no problem, it is really neat stuff. If you check out the comments in one of my other videos ruclips.net/video/TEsMSfoJLZ4/видео.html there is a link to a research paper on lime that is worth reading.
The lime putty that you had in the green bucket was covered by some water (it was in the other video). In this video there is no water on top anymore in the green bucket. Did you just mix it in or did you pour it out before making the video? If it is still in the bucket (I can't tell for sure), how did you take out putty from the bucket? Would be useful for me if you actually filmed it, but I guess it is too late. Maybe a trivial question but I have never done this so I am learning. Thanks.
The water is still there, if you look at about the 3:45 mark you can see it as I scoop it out, the extra water is there to 1) allow the mixture to absorb any water that it needs to be fully saturated and 2) it makes a barrier seal so that the putty does not dry out. As far as I know if you keep a layer of water on the putty it lasts somewhat indefinitely
You need well graded sand. Sakrete all purpose seems okay. It’s has small aggregate down to dust. Then you should do a saturation test to see how much putty to use. Mine was 1 putty to 3 sand plus and extra 1/8 putty.

What`s the best lime-to-sand ratio for indoor applications?

Approx 2 1/2 foot thick foundation.

Thanks for the video 👍🏼👍🏼👍🏼
As refractory mortar for rocket stoves, you could mix a bit of cat litter or bentonite to make it real sticky. Add pumice or vermiculite if you want.
Should've used Hydrated Lime! Also, just filling in the crack will actually make things worse over time. You need to chisel out all soft mortar just past half of the brick and then fill it in once washed and brushed. What you're doing is only covering up the problem instead of fixing the problem.
Do you make or buy hydrated lime?
This is hydrated lime. See his videos for making lime putty. He made the putty from hydrated lime
Hydrated lime isn't actually believed to be any use for anything but plasticising cement mortars
so, does the lime putty have any practical use outside of being an ingredient for mortar? Will it dry if used purely as a plaster? Can I shape lime putty into blocks ?

Does the putty have to cure for an amount of time before you use it?
No

Oh, I did not see this part when I posted my question. Thanks!
No problem, glad to help
Hello, what kind of sand did you use? Is it just any all-purpose sand from home depot? Thanks
Nat Regalado thanks for asking, I used mortar sand, it was quicrerete brand but yes any relatively fine grain sand will work
Aperture Now would hydro sand work?
You need well graded sand. Sakrete all purpose seems okay. It’s has small aggregate down to dust. Then you should do a saturation test to see how much putty to use. Mine was 1 putty to 3 sand plus and extra 1/8 putty.
Will beach sand work?
LIME IT UP.
