I just want to point out that at 26:00, the brick were destroyed but the mortar remained. That brick only lasted 50 years? And frankly it's all destroyed. Whereas, the early 1900's buildings with lime mortar are 120+ years old, and need repointed and some brick replaced. A water table would have helped tremendously on those early buildings.. (Lime mortar is a great mortar, I what I'm getting at. But straight Portland for ground contact is a must, or at least Type S. I'm a mason like Mr. Madduck, but he's got about 30 more years experience..lol. I live in western PA, he lives in Eastern PA. Same weather. I do lots of small repair work, same as him, after 20 years in mostly new construction. Stoops and chimneys are the absolute worst with a lot of the modern-ish "cheap" brick. I've had to repair so many. Many times the old timers used incredibly hard mortar, which magnified the problem. Plus...Portland is a hydraulic cement. It forces the water to go through the brick instead of through the mortar, then freezing and expansion destroys the brick, instead of the much easier to repair mortar.. Lime mortar also repairs itself and re-calcifies..

So if you have a concrete foundation with spalding, would you clean and cover that concrete with Portland (if it’s too hard and causes substrate to crac) or just type S? Would you cover with a dry lock or a waterproof mortar?

The most important thing for wall longevity (stone or brick)is that the roof of your house hangs over at least two metres away from the exterior walls around the entire house so that the rain and sun never hit the exterior walls at all. I have seen 150 year old stone houses that have no mortar falling out and the stone work remains in place and I am talking about mortar made of lime and clay earth mixed with small stones. The lime stops mildew and mold but the clay/lime mortar though not the strongest works perfectly well since the walls do not get hit by rain and the humidity in the walls does not fluctuate much.

[@MikeHaduck]

Thanks ,I agree, Mjke

[@mikemorgan5015]

Water is the universal solvent. It's what mother nature uses to reclaim just about everything. It rots wood, destroys foundations, turns brick to powder, destroys windows and doors, breaks big rock into little rocks, turns solid steel into red flakes, and on and on. If you build, a large roof overhang will allow your building to last almost indefinitely as long and you maintain the roof. Your paint won't peel, and your masonry will remain pristine. 2 meters is a BIG overhang!

One of the traits of the lime is that if it gets wet it swells enough to close the tiny cracks in the mortar so that it will not absorb water. Lime mortar does not stick to the brick or the stone and that is where the water gets in at. The lime over time gives up and all you really have left is the sand. to day there is hydrated lime and you can get unhydrated lime. The mixing of the portland and the lime works well but I agree that the mortar should not be as strong as the product you are building with be it any kind of brick or stone. If the mortar is to strong the bricks will crack instead of the mortar allowing movement. All brick and mortar walls leak to some extent. In today's construction flashings are used to allow that moisture to get out of the wall with flashing and weep vents. In today's construction type S is used on most structural block walls because of the amount of rebar and grout used to fill the voids in the blocks. A typical Wal Mart store in my area will be built with 12" concrete block with vertical rebar every 24"s and horizontal rebar every 4' in height all of that grouted solid with grout made from 3/8 or less pea gravel, sand and portland cement. This stuff is extremely strong. there is also wire reinforcing like in this video everyl 16" in height. The amount of sand in the mix helps in making the mortar stronger but it also affects the workability of the mortar. To much sand and the mortar will not stick to the mason's trowel, to little and the mix gets to sticky and the mason can not get it off his trowel. The portland is what gives the mortar strength. Type N or 50 50 will still make mortar so hard that you can not drive a line pin into it when it is a month old. There is much to say about these subjects and like Mike geography and experience will teach a lot. I am in the St.Louis Missouri area and know full well what freeze and thaw can do. The architecture in St. Louis has a very large amount of turn of the century homes and buildings made from bricks. PBS television has a great documentary on the history of brick in St. Louis. Some of those old bricks sell for more than new ones.

Excellent post Mike! Really helpful. Your channel has very quickly become my most helpful of late. I just completed the rebuild of my son's brick chimney and it looks awesome. It is all because of the information you've passed onto people through this channel. Contactors wanted $7500.00 to do this job. My son and I completed it for $1100.00. Two of the guys who bid on the job came by today and commented on the quality of the completed job. They both asked who did the work. When I told them, they didn't believe a machinist and a retired 1st responder could have done it. My son's neighbors confirmed that 2 D.I.Y.ers did in fact do it. It took us a lot longer than a Mason would have but we did it and it was all because of the things I learned watching your channel.

Living between several different regions of France, it's always fascinating to see how the rocks used for housing changes. Nearby we have towns made from rock formed/transformed from a huge meteorite impact millions of years ago, further east it's volcanic rock, to the north its limestone etc. My house and barn is granite rock, which is the local geology, it's about 200 years old. At some point I need to repoint parts of the barn - it's still holding up very well, but aesthetically it doesn't match the house which must have been repointed within the recent decades. All the old houses here are done with a lime mix, and it is what I will be using. The video was very well put together - it's improved my understanding a lot. Thank you.

Thanks, Mike for another good one! One of your best. Keep up the good work. PS I remember my dad, putting lime in the mixing trough and adding lots of water. It had to sit like that bubbling for quite awhile before you could do anything with it. I think it was called slaking? I don't know what he did with it when it was done, ( I was something like 4 years old, now I am 80 ). I remember he said don't touch it or go near it that it would eat your flesh and bones. Also said the racketeers would dispose of bodies that way??? Funny what you remember, hahhaha.

[@MikeHaduck]

Hi Jim, I wish I could have seen it, by my time things had already changed, good memory, thanks mike

[@geraldtanis9322]

I was taught the trade by two old timers who taught me the methods for "Brown and White Coat" interior plastering. "Slaking the lime" was done (in a 55 gallon barrel) to create a putty that when it was ready, you would make a ring of it on a board- about 2' around, and then put water in the center and add Plaster of Paris. You mixed it all thoroughly and got it to the mason who went like crazy to get it on the wall or ceiling before it hardened. The white coat was less that 1/4 thick, so it was very important that the 2 brown coats underneath it were put on accurately. The first brown coat was called the "scratch" coat. The 2nd brown coat was applied and finished with a wooden "float". Then came the white coat- It was troweled smooth and a brush made from Chinese boar bristles was used to wet the plaster ahead of the trowel. There were some neat tools we used- one was called a "darby"... and the wood that was used around doors and windows were called "grounds". It was used to determine the outcome of the finished product so the trim could be applied... The original part of my house (1928) is plaster over wood lath and it's beautiful yet- even though it's almost 100 years old...

[@msdiego2k]

Thanks nice video! You should also point out that there is a difference between "normal" lime and NHL 2 / 3,5 / 5 (and also HL 2 / 3,5 / 5). The NHL 3,5 which the used at the castle, is pretty much as strong as a 50:50 portland-lime mix.

[@MikeHaduck]

Thanks, Mike

[@demammoet]

Ahh, I thought only NHL 5 came close to Portland's hardness. I trust Mike's experience. I'm however interested in line still. Basically one of lime's issues was that the old timers had little means of having uniform materials that science could check before Portland took over. There may be a place for lime in freeze/thaw heavy places. But it's most likely a niche not yet found. Mike's making me wonder a little though, I haven't seen anyone in their right mind advise lime for ground work inside or outside the lime mason community. Maybe lime is just for temperate to hot climates, I'm by no means an expert. All it's attributes are known to have frost highest on it's problem list. Lime most definitely needs a good "hat and boots". And any place in PA would have you worried about it's"set". If it's not hotter than hell it suddenly dips into freezing on a spring day, either way it's humid.

[@deninsrmic4165]

Indeed, I am surprised that no word has been bread about NHL 3,5 or 5. NHL 5 would have been better substitution for cement as its more breathable than latter. Here in Europe, when it comes restoring old buildings we still use lime without mixing with Cement, although I have seen failed brickworks pointed with cement instead of lime and it was sad to see old soft bricks spalling and falling asunder. Many of the brickies tend to use cement on old buildings without even knowing that they should not. Has NHL been tested in Pennsylvania Mike? This nevertheless is still very informative video, many thanks for that?

[@MikeHaduck]

Hi, they don't sell it here, most of buildings are under 100 years old not like Europe, it's either mortar or Portland, if I was to buy it I would have to send away for it, thanks Mike

Thank you so much for this video. All the old house experts, blogs, etc. make it out like Portland is the devil and if you repoint your house with Type S, the bricks will fall apart. Thanks for setting the record straight. I have been worried about my circa 1840 house in Kittanning because at some point it was repointed with a hard Portland based mortar. I asked a number of these experts what I should do and they said I needed to rake all the Portland out and repoint with lime or my house would be screwed. I knew I wasn't going to actually do that, as the masonry is in pretty good shape. All of the masons locally told me they don't use lime and most of them recommended Type S. These guys seemed to know what they were talking about, so I knew something didn't add up. Your video needs to be seen by more people.

They say something like a N or O (like the interview with the guy at the cathedral). With hard stone (igneous) or modern bricks that have been fired to higher temps you can use a stiffer mortar. I got in to researching this because my basement walls are a soft stone (built about 1900), it was parged at some point in the past and now that is spalling and is growing efflorescence so I know and I'm going to have to have it dealt with.

I'm going to say I agree with you that PA weather destroys everything. There are situations where you just have to use limestone mortar though. There are different strengths of lime mortar that have been developed over the years that are still softer then Portland but can still breath and not harm older brick. Low to the ground for example where you you might get a lot of splashing from a hardscaped ground surface and mortar washing out you would use a harder NHL 5 Lime morter mix as apposed a softer NHL 3.5 mix.

Great video and it covers so much, but I disagree with saying that lime mortar doesn't last.(in PA) You're pointing to buildings that are over 100-120 years old, some 140+, and they are still there. Lime calcifies and becomes harder over time. It can also repair itself, as a crack can get wet and re-calcify. Lime mortar is still used all over the world, and does need..maintained, but do does a Portland based mortar over time.

It's been 3 years and a couple of the bricks have started to spall. They had pointed it with St. Mary's N-type mortar. I looked some stuff up and found some places saying that chicago brick should be pointed with lime because it's a soft breathable brick and any portland makes the mortar too hard for the water to espcape the brick and it cracks. What's your experience with that? what should be used with it? I live in SE MI. The climate is pretty comparable to PA. I should mention, I recently redid my basement window sills with a 1:3 portland/sand mix, and I was worried that it may cause cracking with the bricks it's attached to since I didn't use N or S type mortar cement. Thanks for your help!

Hi ,Mike, the problem is usually the soft brick, I recommend to a customer to cover the whole top with metal and a large overhang, sense then he has had no problems, thanks mike

[@MikeBotrosDIYHomeGarden]

@@MikeHaduck thanks for the feedback! Luckily most of my brick is doing fine being covered. They’re are some that are spalling on the side of the chimney above the roof facing north, where the sun doesn’t dry it out enough. I’m thinking about spraying a waterproofer on it to help prevent water getting in and causing the bricks to spall.

[@boots7859]

@@MikeBotrosDIYHomeGarden Not a mason, however if brick has been laid and its a soft brick then a matt or low-sheen waterproofer sure seems like the best/only option.

[@akaredcrossbow]

@@boots7859 I agree! Chimney’s/brickwork should have waterproofing every 3-5 years to keep the moisture out. Only waterproof your chimney if it hasn’t been wet in a week, don’t want to lock in moisture.

[@MMGJ10]

@@akaredcrossbow Make sure you use the correct waterproofer as well. A penetrating sealer that allows the brick to breathe is required. Anything that top coat seals it will trap in moisture and destroy it.
