You mean different. If it fires the bricks it's correct. If it doesn't it's wrong. This is how you think logically.

Understood. But how do you keep water from infiltrating house walls, ceilings, dripping on Inside of windows if there is no seal or drip edge on horizontal and vertical timbers? Really hoping someone can tell me. I am new to this house and the damage each rain storm is significant. Thank you.

Very good to see quality knowledge of lime in use for construction on the youtubes these days compared to about a decade ago...thank you. I'm looking to do a stone masonry knee wall with a lime mortar. A timber frame structure. And a wall enclosure with either straw/lime or a hemp/lime with lime finish. I wonder what limes to use in each case?

Nice Diagram, BUT: how can CaCO3 AND Ca(OH)2 BOTH be "Calcium Carbonate" as labeled?
@Babipoki Жыл бұрын
Correct, Ca(OH)2 is Calcium hydroxide/slaked lime.

Here's some simple observations. Underground where it's wet a strong mix is used and not just lime mix mortar cement is added.Pointing should be a stronger mix than the underneath mix which was laid and one reason non cement{old lime} buildings have moved terribly over the years is because they didn't use cement{or not as much}.Cement is added to make a mix stronger so if done right it doesn't move in the first place so if wanting a building to "breath" is so good then why is cement used at all anywhere?I've pulled down many an old lime mortar wall over the years as well as old strong cement based walls and I know which ones have rotted the most. Given a choice of hacking off an old lime plastered wall or a hard cement render I know which one i'd choose and why.

@Scribe31682 жыл бұрын
I have found a potato masher and a household manual cake mixer quite handy for extremely small batches. Running over a mix to and fro on my skateboard has had the same effect as those large and much more expensive pan mixers.
@ironimp12 жыл бұрын
Personally I think your mix is lime weak: Taken from Dr. G Lynch 'Myth in the mix': Misconceptions concerning the traditional method of gauging quicklime to sand have contributed to some mortar failures based on a volume ratio of 1:3 with ready-to-use lime, particularly where inexperienced personnel working with lime putty have not realised that a measure of lime within a ratio might not be one full unit of lime. Lime putty contains a sizeable percentage of water; thus reducing the actual binder content within that ratio further.

This should be the top result when searching 'lime mortar'. Incredibly well made video. Has everything in it. Btw in my research I found out that MY HOUSE of the 17th century has a cement render. The reason I'm guessing is that it wasn't a protected monument before that and people have been mutilating the building before that. Perhaps they pointed it with cement and found out about the damage, and then put on the cement render. I'm guessing the best course of action is to take it off, then take out the cement pointing that is possibly there. Then repoint it with lime and plaster with lime if wished.

I really enjoy hearing absolute experts. Super Experts are not always valued by Management - Because Management would rather employ generic employees who know a fair bit about many things but may not have the depth of knowledge that specific real experts have accumulated over the years - plus the newer staff will just go along with a boss who wants to save as much money as possible. Younger newer employees still learning their trade may not even know about different mortars. Whereas real expert and very experienced people who understand why some other solutions will be better should be paid accordingly for their specialist expertise. And when you come across these super experts they can concisely, logically and expertly explain the WHAT, WHEN, WHERE, WHY and HOW without any useless waffle. Worth their weight in GOLD.

Hello What kind of lime mixe would you recommend for a 1940 brick building that is located in new brunswick Canada on the eastern shore for repointing? Charles Thank you
@Ev-eq8zn3 жыл бұрын
Hi Charles. I used to do heritage work in Canada (Toronto). Tough to say, 1940s, good chance it's a weaker cement/lime mix. Cement was definitely used in Canada at that time, but maybe not ubiquitous. Code will say use a "Type O" mix for restoration, like on the parliament buildings in Ottawa for example. I forget what that exact mix is now, but you could try a 1:1:6 Cement:Lime:Sand or weaker. If you can get NHL 3.5, a 1:3 or 1:4 mix would do. Hope this helps.

It's all about cost and ignorance... a bag of cement is alot cheaper than a bag of hydraulic lime or a tub of lime putty so the modern day builder (who very rarely has any concerns about heritage or conservation) will always try to sway the client towards the use of cement based mortars /renders...... also there's probably the best part of 5 generations within the construction industry who haven't been taught about traditional techniques, methods and materials so they have no idea about what materials should be used and in what situations...

I use a mattock handle on it holding the mattock by the metal end and pushing it handle first into the mix in a bucket, really seems to squash it in, alternating with trowel mixing. I have tried both washed sand and kiln-dried sand. Washed sand seems to work best, with 3 parts sand to 1 part putty, hardens well over a few days. Kiln dried sand needed about 1 part sand to 0.55 parts putty to get a workable mixture, and takes lots longer to dry. This might be something to do with the higher putty ratio. I think the washed sand has less fine clay and organic material, but moisture content is rather high. Also the putty can have variable moisture content. Still learning how to do this.
