  Can you talk about lime mortar used with Accrington brick . Any experience repointing ? often existing mortar blackened with coal dust or naturally white but excessive hard very thin joints which the brick doesn't absorb much moisture from the mix .

  I’m in an ongoing process of slaking a load of lime putty with quicklime for top coat plaster. I know they say ideally it wants to mature for at least 4 months before use. I’m going to hold off using it as long as possible but if I have to use some of it fresh will it still be ok? How does the maturation improve it exactly? Is it purely workability or will the end product be affected?

  I got the badge and would get th t-shirt f sure, the times my partner walks in while im cooking or sipping some green wine and she says "you watching this guy again..!?" Hellas.. Very useful content thank you, we are reviving an old house in SE Portugal, most of the stone work is schist with lime rendering and pointing, at least what survived the last round of renovations that include whole walls in cement render.. Question: all of the original render/pointing has been done with a medium brown lime, coarse/ish sand, no hair, but it's brown or latte color. across the boarder in Spain I have been able to source hydrated lime that is latte colored, but it's a CL70, is this dogshit? we are just using it for plastering to mix & make the Secil lime warmer really, but Secil is the only stuff we can get our hands on.. there is some Keracoll stuff too that is 3.5 but comes as a ready mix and it's 20£ bag.. "breathability miracle" they sell it as.. The local builders use only NHL5 mixed with cement to tell clients it has lime.. it's sad to watch..

•

  The brown lime plaster may even be earth/lime. There's still some around. CL70 is fine but you'll have to be careful slaking it as it's usually got a slow burn to it so you can easily drown it. Never buy premixed NHL because that's the dog shit stuff. NHL5 mixed with cement is just really bad. They don't need any cement whatsoever. "This guy" 😂😇 Ha ha!!

  @michaeljamesdesign ive actually attempted to fire limestone four times. On the last time, I reached the nearly 2800 degree mark for an hour and was so excited.... but, I noticed when I finally unloaded my lime a strange sulfur smell and knew something was wrong... but, i tested it anyways... taking a small amount and adding a drop of water... no reaction. I thought what the hell now!?! Then, I had a random thought of that sulfur smell... and, I quickly googled the formula for gypsum.... and, wouldn't you know, the fine 100% all natural high purity calcium chalk I used, was not actually chalk, but gypsum! I was devastated because firing large quantities of the fine powdered garden lime proved troublesome as to obtain the temp supplemental air is required (for a small campfire sized pit), and with powder, poof, gone like a fart in the wind. Second attempt, I welded a contraption that solved the blowing away issue, but instead ended up with so much ash, charcoal, and foreign matter in the end product it was useless.... and, the metal surround reduced the amount of heat exposure to the lime. Attempt three, adjusted my contraption, solved the debris problem, but couldn't get high enough temp for long enough due to wet wood. And then I switched to chalk because It was much easier to handle, lacked the problem of blowing away and even if debris got in, the chalk pieces were easy enough to remove. Just a little post fire sorting party. Lol. 🥳. And, I the stage was set, had dry wood, charcoal for the bottom, and an open enclosure. The flame was white, the chalk was glowing, which made me smile as you know when you've got the good stuff when your limestone glows luminescent usually. So, i was excited as a pig in shit, even recorded the whole process post-glow. So, you get 20 mins of me explaining and with a child like Gettiness. And, then, no sizzle... cue insane cussing rant of epic proportions at 5am, in suburbia, and....that video was erased from existence out of utter shame and devastation. Lmao. So, it's a work in progress, plan on trying again when I can get my hands on enough free limestone or "real" chalk!

  @michaeljamesdesign8 күн бұрын

  Thanks for the comment John. There's a saying that a good example of pointing looks like a bad example of plastering. There's a lot of truth in that. Although most of it is gone, there used to be many examples of a half and half pointing/rendering way of partly covering stone. It was sooooooooooooooooo rustic and appealing to look at. It really resonated with the senses. I find that as these older properties age and become more dilapidated because of lack of essential maintenance (mainly in the south of England) that I'm now forced to knock back much of the friable stone. The result is this semi-rendered finish. Looks lovely. Takes a bit of skill and know how but as long as there's a combination of stone and lime mortar showing it's very aesthetic.

• 
  @michaeljamesdesign10 күн бұрын

  But if you've got a good lime mortar then there'll be no need for Stormdry. You've got to look at the use of old buildings. Many of them were used to store food products. For example, mill barns where flour and grain was stored. These large lime and earth mortar built storage units would be located close to the river because that's where the mill was. If flour gets damp then it goes rank. If grain gets wet then it gets moldy and people starve. That's why lime had to work. There's just as much need for Stormdry now as there was then.

• 
  @michaeljamesdesign10 күн бұрын

  That's good. But what you have to bear in mind is that recessed mortar means there's less of it to pull moisture away from the stone or brickwork. The result is that harmful salts have a longer dwell time which means that stone erosion is speeded up. It also means that moisture hangs around longer. The upshot of this is that the freeze/thaw cycle has more of an impact in winter so weathering is accelerated. Jus' sayin'.

  The chemical formula is different. Lime hydrate is calcium hydroxide but lime putty (which is fully slaked) is calcium oxide. Lime hydrate is not as good as lime putty. The finish ain't the same.

  Limestone and chalk both contain calcium carbonate CaCO3. 'Burning' calcium carbonate causes the calcium carbonate to decompose to calcium oxide CaO. This is called Quicklime. 'Quenching' or 'Slaking' the quicklime with a limited amount of water results in an exothermic chemical reaction which produces calcium hydroxide Ca(OH)2. This is called Slaked Lime. I'd be interested to know what people in the industry mean by 'lime', 'hydrated lime' and 'free' or 'available' lime.

However, I do appreciate the comments raised in this video regarding traditional construction. I do note that the roof on this building is a modern replacement with some poor detailing. Too many people think that the mortar between the stones or bricks/blocks is there to stick them together - it is not, it should be regarded as being there to keep them apart. Indeed, simple sand bedding can be as effective as any other mortar so long as the sand is prevented from leaching out, which is what the lime and the cement does as they act as a binder

  Hey Clive, well pointed out. I was only just looking at the roof and also the stud walling upstairs. All fairly recent. I'd be interested to see what it looked like previously. I would assume pantiles. Sorry if I caused offence with the plonker comment but I got sick to death of the so called "conservation architects" in the south of England - particularly Oxfordshire. Many of them were just chancing their tails trying to secure work on grade 11 listed properties as there are so many of them. It's interesting that you should point out the sand bedding mortar as well. I mixed fine Bath stone dust with nothing but water and it set like cement. Far harder than earth stabalised mortar.

  @@michaeljamesdesign Too many historic building professionals are not conservationists but preservationists so that they have to replicate whats there instead of creating a building solution and I suspect because they really don't understand construction. I worked on Coombe Abbey and there we had the original Cistercian monastery, a Jacobean manor house, a Renaissance stately home and a Victorian revivalist extension all in one building, with major Georgian stables and Real Tennis building all sitting happily together with each being the latest and modern style of the day. That brought into sharp focus that buildings need to evolve and change, even when repaired otherwise they deteriorate and become less relevant and lose their character. Fortunately, we had an excellent contractor and a great Conservation Officer and LA Building Control officer and that relationship has lasted, with at times when we often consulted each other of various aspects on other jobs long after Coombe Abbey was completed.

  @@clivewilliams3661 This is it. Beautifully summed up. And if a solution is born out of a lack of architectural understanding coupled to unrealistic client expectations where the completed project is concerned then often the result is often a green-washed mish-mash of modern and traditional products and finishes. Particularly if it's a commercial venture.

  I’ve long suspected my Victorian property has earth lime mortar in the internal brickwork and plastering. Would it just be the earth extracted when digging the footings?

  I wouldn't know. What it will be is a low organic matter content colloidal soil.
