Natural Hydraulic Lime: Mixing Lime Mortar
Wish I clicked this video earlier. Clear what the mix is and what it can be used for.
Hi,what would cause mold and orange spots on freshly lime plastered wall? We used NHL 2 about 6-8 wks ago, we have not put on the skimming layer yet and we have noticed in the corner floor level these mold and orange spots? Help?
great video thanks - what sand do you use please?
sorry - just saw the sharp sand comment below. Any guidance on washing ?
That is not how you point at all. What a horrid mess of a job.
What sand is that ? And why you not wearing a mask ??
great vid, would you add sharp sand, if so in what ratio :)
how does this set with no cement
The lime sets it off slowly
how do you get the bice beige / yellow lime mortar though
i wish these tutorials educated more about the actual types of lime. like what hydraulic lime is for and when to use hydrated lime
what type of sand is used here?
so we want the moisture before pointing? Should we water the stones just before?
In this part of a longer talk? Is the full version available somewhere?
so if you want to mix another mixerfull you have to dry out the mixer that wouldnt be great
Do you just use grit sand/sharp sand, not mix sharpsand with building or yellow sand?
What ratio would you use for structural walls?
I suspect that that lime has at least some cement in it whereas I believe Saint-Astier does not. Also it is preferably to drop down to a NHL 2 mix as this is more breathable and less brittle.
Is Lime mortar appropriate for repointing a 1950s sandstone retaining wall (about 8 feet tall in the center, and tapering down to 3 feet on each side with the surrounding slope) in Pennsylvania? I haven’t had the failing mortar analyzed, and am not sure if Portland has been used in the construction. Any guidance you would offer is much appreciated.
Hi,nice and informative vedio,please tell about lime and clay or sand bricks,can we make it and are these bricks eco freindly and waterproof? Please for lime meter and for wall plaster which materials use with lime and how much ratio of each??
Thanks for the video, what kind of sand is needed for this mix? thanks
where's the whiskey?
Thank you very much.🇦🇺
Use a mechanical tool and put the pinnings back when pointing.
Brilliant. Thanks for that. I understand there is a preference for using hydraulic lime, not so easy to get and expensive, as opposed to Hydrated lime easily sourced in building merchants.
No mention that Lime has been used for thousands of years Obviously no clue
👍👏
No cement ? 🤔
Can I use that mix for flooring?
Calm down calm down……🤣🤣🤣🤣🤣🤣🤣
Would a more accurate way, for the quantities if you have time, would be to weigh the sand and lime mortar? Eg mix 3:1 use 30kg sharp sand 10kg lime ?
Sand weight will vary dependant on water content. Measuring by volume is more consistent than by weight.
Wow gauging bucket! Wow 🤩-
What a mess
Nice video buddy, I'm about to start indoor lime rendering, the video has helped a lot.. would you happen to know how many grams of horses hair you would add to your 1 lime to 2.5 sand mix, for a scratch coat
2:22 Comparing cement with lime: (cement has) "..3 materials that have to be individually quarried.. With Lime, we have one material"... So why's lime so expensive then?
Hi, I live in a stone cottage in west wales (approx 200 years old) and it has a roughcast/pebbledash external render. How can I tell if the render is a breathable render or cement? Any advice or videos on this would be fantastic!
While I like the Irish accent in English, it always reminds me of the sad state of the Irish language.
Can we use slaked lime also. Please help it will be helpful for us.
By the way phone is under my husband 's name, not mine.lol.
William Freeman who came to America in 1635 on the ship, The Abraham was my ancestor. On my grandmother side. She was born a Freeman. Same set or different set from Cor Castle set?Just curious.
Just 2.5 of builders sand, not any grit or granite flakes? Or would you substitute .5 sand for grit or granite chips?
What is the difference between hydrated lime and hydraulic lime and what is the formulation of hydraulics lime
Hydraulic lime has "impurities" from burnt clay that allow it to set without air (e.g. underwater). Natural Hydraulic Lime is made from burning limestone with clay impurities. (Artificial Hydraulic Lime is lime putty with "pozzolans" added, like fly ash, metastar, brick dust, or volcanic ash (used by the Romans).) Hydraulic lime sets faster than pure lime putty, and is less breathable. NHL 2 is typically used for indoor work, NHL 3.5 for outdoor, and NHL 5 for very exposed locations (and things like limecrete floors). Hydrated lime is powdered lime typically used as a plasticiser for sand and cement render. You can mix hydrated lime with water and chemically it is the same as lime putty, but it isn't as nice to work with. Apparently, if you let it "mature" long enough, it is pretty good.
What type of mortar/mix are you using here? I have a stone wall that needs to be re-pointed and am not sure what type to go with. Nice work, and thanks!
He is using a hydraulic lime.
Why aren’t the mixers using masks?
What the sand mix? 🙄
Fooking awwwwfull job
You don't put the water in first, like with cement ?
what sand? Looks like sharp not soft/building. In a mixer you should put some water first to avoid sticking!
All lime no matter which lime takes 29 days to cure, in cold, winter takes abit longer, hydrolic lime sets more if exposed to water like under bridges stuff used for etc, hydrated does not set well by it self quick unless its used in conjuction with pozzalons, which are like cement used in rome eyptain time, modern cwment is damaging to building insideor exterior, if cement blocks u can get away with it depends background but not great cement as it holds water freezes in winter then craks alot haurline craks water seeps in motar u got damp wet wall
Been looking at lime mixes for a binder material, Sadly the NHL is excessive cost in the west coast area of the US. I've been looking hydrated lime with a Pozzolan additive to have a similar result that is affordable. Hopefully NHLs will become available locally to make them more attainable in the future.
Fantastic lads 👍👍
I thought that lime mortar mixing should occur in a flat puddle
