efflorescence, what is it? (Mike Haduck) commentary
Вставка
- Опубліковано 28 сер 2024
- Mike Haduck gives his opinion on how efflorescence forms on masonry. This commentary gives examples of how I believe the substance forms and the reasons for its appearance. All my videos are my ways and ideas, I always suggest anyone doing any type of work to consult professional help.
A very minor clarification:
" Effervescence" is the escape of gas from an aqueous solution. Pop the top from a can of soda (or beer) and hear the bubbling and fizzing? That's "effervescence".
Efflorescence? Mike's done a fabulous job of explaining what that is.
Two long, very similar sounding words. But quite different meanings.
thanks Drew, I appreciate it. mike

He got it right in the caption
@@samsngdevice5103 There's nothing wrong with wanting people to know whether they are saying it right man.
@@crusheen absolutely. The dude made a video and didn't even know how to say or spell the main bloody word. Then that Samsng Device idiot attacked the person who rightly corrected him. SMH.
Efflorescence is ANY soluble mineral that is transmitted to the surface of masonry. It usually happens more often in the winter because the masonry holds water longer in the winter. When the masonry holds water longer it gives minerals more time to migrate to the surface than in the summer. It can be salt but it also is any type on mineral in the wall that can dissolve. Cleaning with acidic washes can sometimes aggravate the problem. Wet the surfaces thoroughly before proceeding so the cleaners work on the surface not in the masonry below the surface. Always do a test spot and wait a week to see the result. Efflorescence can not happen without water travels through the walls. So to prevent that look at caulking joints, copings or caps, flashing, roof over hangs, drainage from roofs, drainage from wall bases, open joints, cracks, and breathable sealers to minimize water entry to the masonry. They are now developing concrete so dense it is waterproof which will help concrete structures made of poured concrete. Not sure on the way it will affect mortar joints as you don't want then harder than the units they are laid in. You can dry brush some off, used cleaners, soak a walls surface to soften it before cleaning but it can be very hard to remove without damaging the surface you are trying to clean.
well said, thanks mike
You say 'they are developing concrete now so dense it's completely waterproof'. They have had the ability to do that well over 100 years now, the additive is called 'Anti-Hydro'. I believe it was invented in 1902. ..but it's not cheap, so it only makes sense to only use it when necessary. I use it for natural stone fountains and waterfalls in and around pools. And it works GREAT, I never have any efflorescence on any work where I use 'Anti-Hydro'. 'Anti-Hydro' is the original and ONLY product I use. There's a lot of garbage junk trying to copy it and being sold cheaper. I used to work in a lab, and it really is junk. Don't touch it, no matter what the slick salesman (who knows nothing) says.

Excellent and informative video Mike, I always learn something from your approach and I'm an experienced old Landscaper. But never too old to learn!
I appreciate hearing that from a professional thank you much Mike
Another excellent video ! You are truly a Doctor of Masonry.
Thanks Mike for another interesting video. My back garden wall is about 120 years old and has a mix of efflorescence and old whitewash all over it which makes it look a real mess. I'm going to wirebrush it all off then paint with Portland as shown in your other videos.
Hi Londonfog, I would also consider and masonry-deck-stucco paint for the finish, the idea is to keep the water from getting into the wall from the outside , especially the top, I hope it helps, thanks mike
+Londonfogey - Please be aware that if you have a situation like in the example at 5:12. It's not coming from the top but rather from the bottom. It happens by capillarity, meaning the minerals content from the surrounding soil are pushed out of the wall by the moist. So make sure you "treat" the reason why the moisture appear in the first place.
Most important allow the wall to ventilate/breath. So NEVER cover it with rubberized paint, non breathing mortar, etc. Good luck.
Thanks crpth1. As far as I can tell the efflorescence was caused by soil piled up against the wall to a height of about 2 ' more than it should have been - it had probably built up over at least forty years. I removed all this soil, painted the wall with Portland then a couple of weeks later did a top coat of water based breathable paint. Hopefully it will be ok, it's not structural just a boundary wall so it doesn't need to hold anything up!
thanks crpth, I believe that and have seen what you are saying,, with the paint it all depends on where, what and why, I appreciate it. thanks, mike
Mike Haduck - I've seen some of your videos. Pretty good job you did on them. Thumbs up. ;-)
Hey Mike, you can't remove efflorescence with a water sponge, it will only disappear temporarily when wiped with a moist sponge it will be back to what it was after a few hours of drying.
And I would like to correct one other thing, there only one type of efflorescence the other type is only efflorescence build-up.
Hi Hantz, I hear what you’re saying, but I’m confident about what I said in that video, I appreciate it Mike
I do building inspections and find cinder block gives off mineral deposits both as mineral salts which are whitish and mineral oxides which are dark metal oxides. Moisture being the universal solvent will dissolve these minerals, especially calcium and iron oxide to produce conditions often mistaken for mold on walls. I use the stillagtite example to explain this to my customers to.
Thanks Paul, that's a good way to say it, Mike
Efflorescence is from water that has salt in it. The water dries and leaves the salt residue. A chimney that has gas venting through it creates a lot of condensation and salt, a natural byproduct of natural gas.
Thanks, Mike
Those geodes you show are everywhere in Ozark country. I was unaware that that is how they are formed. Gracias.
Gracias Tommie, mike
it's goig to take a while to see some of these great video you have archived
Thanks Savio, mike

How to maintain the Balcony condition in New York. Tiles from the floor will crack & track water underneath
Hi Tiger, tiles if the north always have freezing problems, thanks Mike
Thank you for your prompt reply. I really enjoy reading your blot. Once again thank you for sharing your marvelously knowledge with us. Do you have any suggestions. By the way would you suggest I use mortar mix solution paint on top & follow with a layer of sealer put on top to solve the problem.
Hi Tiger, I would do some experimenting and see what you are happy with, thanks Mike
Thanks so much for this video, it was awesome. Subscribed.
thanks , I appreciate it. mike
I'm sure overuse of a high strength Portland mix along with water ingress are contributing factors.A good wall Cap will help reduces water ingress.
I have found diluted Hcl acid removes it effectively.,also tartaric acid removes silicates.
Thanks K, check out my video, brick walls (old school cars. New school) mike haduck, tell me what you think, mike
I have noticed that some of the buff colored mortar mix that I use tends to get more of this. Since I switched to using strait Portland my work tends to not ever get it as often. I'm a mason in the north Ga, area and I see this all over the place on stone and concrete work. Sometimes it looks very bad.
I know it depends a lot on the cement company, come types more than other. hard choice for sure. thanks mike
+ScottTolbert - It tends to happen more frequently because in some mortar mixes the color is achieved with the addition of mineral contents. That's what "comes out".
Mortars with synthetic coloration usually don't have this issue.
Either case in new construction situation is always better to try to control the moist before anything else.
Was that piece from the bridge integral to its structural stability? lol) Are we homeowners wasting our time trying to remediate efflorescence on our foundation interiors?
Hi 65, I Usually paint the foundations white inside for that reason, but the water problems are mostly because the land is pitched to the house and no raingutters, thanks Mike
My interior basement walls (brick and mortar) are experiencing efflorescence in a corner that takes on a lot of ground water. I had a interior drain installed but it didn't help with the wall issue. Would repointing the crumbling/loose mortar and parging help? The house is from 1890-1900. Some people have recommended silpro seal cote and the big waterproofing companies are recommending a super slurry (whatever that is...) Any suggestions? I took down some of the existing parging a while ago but most of the basement is still parged and there's lots of hollow spots.
Hi Matt, I have a whole series playlist on foundation repair, I am sure you bump into answer there, thanks Mike
Hello Mike,
I was told one of the ways you get the white stuff on the brick itself was due to laying the brick wet which can cause it to draw out but I'm unsure. Cheers Luke
+luke medcraft probably true to some point but cleaning it after the job should take care of most of it. thanks mike
I had a handyman tell me to put Thompson's Water Seal on the bricks where I have "facial" efflorescence (house is 100 years old) - I didn't do it because I wasn't sure it was a good idea - would it be ok? Would it help stop the white fuzz from coming back each spring?
MrsFuzzyJammies Howdy mrs, thompsons went to a water based product so I don't use it any more. and I can't say unless I was there to see it. everything matters when it comes to water sealing, I think it would be best to ask the local guys, thanks mike
Sodium Silicate?
I have the efforescence on my basement wall that has my garage above it. The three other wall that are directly in the weather are fine. So what can be the problem with my wall that is co existing with the garage???? Thank you Mike
Hi Joe, too hard to say from here, but it could be the differences in temp, thanks mike
It's pronounced eff flore ess cents
Hi Mike, no worries if I go to florida they say it different, NJ, NY, Cal, and England all have a different way to say it. it is what it is, lol, mike
efflourence is NOT effervescense.
Yes, it's not effervescence, it is efflorescence.
and some brick and mortar are just prone to producing more efflorescence. You could get a bad batch of either bricks or mortar (usually it's the cement). ..I have seen it come from both. I think the theory of it caused by water behind the wall is overblown. It's very rare to get so much water behind the wall, condensation doesn't create that much water. Working in the rain and with wet materials causes more cases of efflorescence than water behind the wall. ..That's my opinion. The water behind the wall theory is a big deal to engineers (who never laid a brick) at the association.😅
Thanks mike
You can't just wipe it off with water. You should use a wire brush. It will reappear after the surface water dries,. There is natural salts in the brick. When the brick gets wet, or continues to get wet, the minerals come through. That''s why you never seal the brick. The salts will lock in behind the seal, and will always show up. You must allow your brick to breathe. Use proper chemical cleaners, and a good cleaning method to get rid of Efflorescence.
Hide lost, The trick is not to let any water get in there at all, and they won’t build walls like they did in Europe and England where the tiles would let the water In, just the way it goes, thanks Mike
Effervescence...isn't that what Alka Seltzer is ?
I could never say that word right, thanks Mike
I have brick on my home, wondering what that was. Now I know, thank you. Is it ok to seal brick work?
hi pony, some do, but If I was going to I would do a sample to see how it works, thanks mike
Hi Mike, i just had Cambridge pavers installed for my driveway and porch. i wanted to seal them now before oils and other contaminants get on them but they said i should wait 6 to 12 months because the efflorescence needs to come out first. what are your thoughts.
Thank you,
Joe
Hi Joe, I did a patio out of pavers and I told the owner same thing, I has to bleed out first, I told him wait out a whole winter and then before next fall before any sealers,,,, I hope it helps, thanks mike
thank you, Mike. have a great day.

I stumble over the word myself. Didn't Shweeps do a commercial about that years ago? I think I'm going to put plastic sheeting on the inside of my stone faced block garden wall.
Thanks , mike
thanks Mike ! :) !
My building has effloressence on brick walls inside the building.
Hi Ithaca, most buildings do, thanks Mike
Hi! Are you saying effervescence? Isn't it efflorescence ?
Hi Paola, it depends on where your from or what country, it is what it is, thanks mike
Isn't that from all the salt and brine in winter ?
Hi joseph,, seepage and moisture mostly, thanks Mike
I call it concrete cancer so I can scare my customers into paying me A LOT OF MONEY to fixe it.
Hi , I don't know how to answer that, mike
@@MikeHaduck
I'm joking. I do a lot of specialty maintainance services and would treat this as limestone buildup. Same substance that clogs coffee pots and faucets.
Knowing chemical reaction is key.
Acidic solutions such as Muriatic, Sulfamic, Phosphoric Or Ascetic (vinegar) will remove scale however surface damage needs to be explored.
Deionizing or Ion exchange with hydrogen compounds may also work but it's too complicated to explain. On sment surfaces abrasion (turbo cup) is a common solution. Wet look sealers may fix it cosmetically - if it disappears when wet.
Clarishield from sherwin williams works well on pavers with dulled out look.
How does a mason take steps to prevent?
my opinion would be to keep water from getting behind the face. but sooner or later like anything you will experience it. thanks mike
Hey mike ! I wanted to let you know how much i appreciate the videos that you made. My favorite channel on youtube hands down, seen every masonry video, some two, three, and even four times. Much appreciated,

Can you apply an Acid?
Hi Vcash, everything depends but it might do more damage than good, thanks Mike
