This is the guy ! Great info he is so well informed.

I'm an electrician by trade and frankly, lime plastering is more confusing than anything I've ever had to learn about. lol I thought I had it sussed, but then I have now seen something that says, don't use sand in a top coat of lime putty, use chalk! WT.. Heck! 😁 The hydrated lime I bought to make the putty with says: mix with water and seal in a tub for a time before applying it (no mention of aggregate?) I've done a fair amount of plastering over the years, but always with gypsum. Now that I'm a convert to the beauty of lime I have taken off much of the horrible pink plaster in my old house and I'm gradually replacing it. My scratch and float coats were a pleasure with good results. But the finish coat is doing my nut!! 😩

Lime (calcium hydroxide) can be made into two similar forms. One is a putty that is sometimes referred to as pit lime as it is stored in pits in the ground below the frost line. You can buy it in sealed tubs or barrels. The longer the putty ages in the pit or tub, the better it is and the more it will cost. A second form in which limes comes is a hydrated powder. It's made using an industrial autoclave. Both kinds of lime are slaked with water to make calcium hydroxide. However, hydrated lime is partially dried to make it a powder. You can buy this lime powder in big bags. Some folks mix the powder with water and let it soak for a bit to make a putty that looks similar to the pit lime putty, although it's not as good of a product and aging doesn't do as much for soaked powdered lime as it does for pit lime. Regardless of which putty you are using, you can mix it with sand to make lime plaster. If you have the choice between the two in the future, always buy the pit lime. It's significantly better.

Thanks a lot for the importand info!!

Its also good as a paint. Gonna last for years and years.

I’m guessing that it would have been important to mention that you’re talking about areas that don’t experience heavy freezes or freezes at ALL really.

Very informative. Thank you! I'm building a straw bale house in the mountains in the USA -- a pretty wet environment. I've been advised to use High Calcium Hydrated Lime, to create a paste or putty, and then let that age for a year before use. Is that correct? Or is it better to begin with Quicklime and then age the putty? Or is there not really a substantial difference in the long run

I don't think Hydrated Lime has any binding properties, it's used in the UK as a cement plasticiser. I think slaked quicklime (Putty) would be better.

Thanks for wonderful info....May I kindly ask you one question regarding Lime mortar usage with Lime Blocks/ Lime stone...I never seen any video where lime blocks ( big blocks) are in use with lime mortar...My motto is to construction of my home by Lime BLOCKS external walls. Can we use lime mortar with Lime blocks as well? As we use with lime stone... Regards from India...Much influenced by Architect Laurie Baker

Non Hydraulic Lime Mortar was used for hundreds of years from the Roman occupation of Europe to the present day. Including construction using limestone blocks. Some buildings have lasted for centuries. So yes, lime mortar can be used for limestone, sandstone or granite block, and brickwork. Indeed, lime is better in some ways than modern cement as it is softer than the construction material, is self healing and moves as the building flexes. So its strength is in its flexibility.

Thank you for your question. Lime plaster is breathable, so it will allow moisture to pass through it and will not waterproof your walls. Traditional building methods that utilize lime mortar and lime plaster are designed to be breathable, allowing moisture to pass in and out. We do have other products more suited to waterproofing concrete and brick. Let us know if you want to know more.

Hi, I would like to use slaked lime for lime and sand mortar. It's for plastering the outside wall. How long does it take for one cm of mortar thickness to dry out in order to be frost resistant. I would like avoid natural hydraulic lime/ NHL mortar.

I'm about to start using lime in my house soon, as it's stone and lime , I need to replace much cement render,.. You need NHL lime and washed sand this is free of salt and some other shit, not sure exactly lol, but it needs to be washed sand I think, I was going to use normal building sharp sand , I'd rather use that sand its easier to buy, unless I'm wrong and we can use normal building sans ,, anyone?

If the repair you speak of to the wattle and daub is just to the plastering, then mix 3mm down angular sand to non hydraulic lime putty in the ratio 2.5 sand: 1 lime. Don't use hydraulic lime, even NHL2, as it is too hard for the earth substrate. Regards, Mike Jackson, M.C.Jackson Plastering.

I think the point he trying make is moisture in a building made of lime will escape through capillary and vapour. Cement will not permit this. Just look at the number of sandstone buildings pointed with lime that have been destroyed through freeze crack cycles. Not BS at all.
