On 2018-11-14 by (mod) - clear like substance that is all over the ceilings, walls, and the carpets

Sutton

It is essential for you to find a doctor whom you trust and listen to her or his advice.

Unfortunately nothing in your photo is diagnostic.

And whatever those dark streaks are on the unidentified surface, it is not effloresence as that's described in this article series.

Given the case history and complaints you cite, besides finding and listening to a doctor whom you trust, it would be most helpful for you to see MORGELLONS SYNDROME

On 2018-11-14 by Sutton

So I’m gonna start off by saying I moved back home with my parents cause the apartment I was living in also had issues and I ended up with sores on my body, needless to say I thought I would get better quickly and yet I was so wrong.

There is a clear like substance that is all over the ceilings, walls, and the carpets and it’s even out in the garage and seems to not care what temp it is whether it’s hot or cold.

Because I have holes in my skin this stuff is leaking into my skin and at first it looked like worms coming out of my skin and everyone including 7-10 doctors thought I needed psych meds and treatment,

how ever then the stuff started leaking out from behind the plastic in our laundry room and into the carpets and I have a white clear worm like stuff that comes out of the holes and I have moments when it just feels wet and also feel this stuff moving on me when it falls onto me, this house is not but like 5 years old, the laundry room seems to be the worst spot of all and is even on the side of our salt water tank that is used for the well

and when I shower I seem to get huge clear worm like things that attack my feet and this is very painful. In fact they fall from my ceiling onto my bed and go into the holes I have which I can feel all of it and am loosing my hair because of this and I’m only 33 years old and have been battleing this for 100+ days now and I’m at my wits end I have no respect for any doc at the moment cause they all think I’m nuts which I’m not.

Could this be anything that someone can awnser for me if I sent some pics? I’m in desperate need of finding out what maybe this could be cause it’s destroyed my life, I really hope someone will give me some good advice that’s not to see my doc or a psych doctor cause I’ve been there done that and am still waiting on dermatology to scrape my skin, is there any resources out here who can help me because

it’s starting to do the same thing to my 8 year old daughter and this has drug out so far it’s been a very hard thing for me to be told I need to see someone and also hard for my family because I can see it and feel it and it doesn’t seem to bother my parents which I don’t know how.

This stuff even when it falls from the ceiling gets in food and will make your food move and look like it has worms in it and it’s super gross and then hurts my stomach really bad and I can see what looks like mucus in my stools and yea I know it’s a lot of info but I’m praying someone out there will have an awnser for me, god I hope someone will read this and reply

I would say it's not the efflorescence that is corrosive it's the moisture and perhaps contact between the aluminum and other materials that would be causing corrosion.

On 2018-06-17 by michelle

Is efflorescence corrosive to aluminum? I have what seems to be formations surround the base of my screened patio support posts and it is literally eating through the metal. I took pics however, my phone isn't cooperating so I can send images. If efflorescence IS NOT corrosive, then I don't know what I have?

On 2018-05-27 by (mod) -

Efflorescence can appear on just about any masonry surface although some are more porous and will display more moisture pick up in this more efflorescence than others. You may even find a fluorescence on glazed tile and although more often it would be at the mortar joints you may even find it on

On 2018-05-27 by Anonymous

Thank you. Does the efforescence apply to light gray bricks in a moisture area?

On 2018-05-26 by (mod) -

Mary

that looks like efflorescence, the mineral salts discussed in the article above. Very often moisture from the ground weeps up into bricks leaving the salt behind as it evaporates from the upper surface. As brick density and individual ground area moisture conditions very you may not see the identical white deposits on every brick.

On 2018-05-26 by Mary

What is the white powdery substance on red concrete bricks, under orange tree? There is no white substance on leaves or trunk of orange tree.

On 2017-12-27 by (mod) -

Dean,

Indeed effloresence can continue to grow crystals after the original leak has been repaired - it can take months for concrete under a tile floor to dry out to a stable moisture level.

I would not rush to replace the tiles - that may be an expensive "fix" that doesn't work anyway as the underlying slab could still be damp, or dampness could cause a failure of the new tile mastic.

Instead I would clean with a vinegar solution, using as little liquid as possible to avoid adding to the trouble, then combine your dehumidifier with a fan blowing across the floor. Increasing air movement will significantly-increase the rate at which the dehumidifier removes moisture from the air over the floor. In turn that will speed drawing moisture out of the slab below.

When you stop seeing rapid water accumulation in the dehumidifier clean the floor again, and repeat the process a time or two.

That should put the kebash on the effloresence that just doesn't want to quit.

On 2017-12-27 by Dean

Firstly I would like to thank you for such a great forum and also any advice you may be able to provide me with in advance.

I own an apartment which has a concrete sub floor and tiles throughout.

I had a burst water pipe which flooded the apartment completely for one day and discovered this upon returning home from work. One inch of water covering approx 1300 sq ft.

After this i have had grout coming away and also effloresence on the walls about 1 ft from the floor.

I have used a dehumidifier in the main living area and its now been about 4 weeks. I tried to repair the walls but the the effloresence is coming back..

How do i deal with this and repair the effloresence form reoccurring.

I was thinking about removing all.the tiles and replacing them with new tiles.

Will this solve my problem. I would really really appreciate your advice and help.

On 2017-12-27 by (mod) - how to get rid of old effloresence damage on a wall

Effloresence damage on wall after leak repair - (C) InspectApedia.com PaulThanks for the nice remark, Paul.

The photo and your text describe a common and aggravating situation indeed.

First, let's see if you can borrow or buy a moisture meter to confirm that there is no ongoing moisture source - we can be fooled about having fixed a wall leak.

If there is no moisture difference in and out of the problem area then I suspect the problem is remaining mineral salts and softened, damaged plaster - at least in the photo your wall looks like plaster.

I would use a shop vac and perhaps a stiff putty knife or cold chisel to remove all of the powdery and loose material. Vacuum the surface, damp wipe it with vinegar, and leave it for a few days.

Then let me know - or show me - what it looks like. If we stop seeing more mineral crystal growth on the surface then it'd be ok to patch and re-paint the wall.

For detailed advice about how to clean off efflorescence, see our advice at EFFLORESCENCE REMOVAL & PREVENTION - What steps should I do to remove efflorescence from my building?.

On 2017-12-26 by Paul

Hi

Thank you for your excellent web page. I have mineral efflourescence crystals lifting pain and plaster on an internal wall and ceiling coving in my lounge/kitchen.

The external source was remedied 3 years age (Flashing to abutting roof).

The problem is that the paint continues to bubble off even though the source has been remedied. Please can you advise what I can do to overcome this. Thank you.
Paul

Hi. A chimney company said I have efflorescence in my basement firebox. It is not present in the fireplace on the main level directly above. The company recommends waterproofing the exterior of my chimney down to the footing, to the tune over over $5000.

They also said I need a new chimney crown. Theses recommendations were made during the course of an estimate for a gas insert install. There is no efflorescence on the outside of the chimney anywhere (unless underground where neither of us can see).

Should I let them perform the costly waterproofing repairs or see if the repairs to the chimney crown solve the problem?

On 2017-05-22 by (mod) - "Treating" mushroom growth

"Treating" mushroom growth really is in my view more of a treat for the wallet of the treating person since "treatments" are not the proper approach to dealing with mold or mushrooms growing in buildings. (Mushrooms are the fruiting body of mold or fungi). Rather you need to

1. remove the mold by physical cleaning as much as feasible
2. correct the cause of mold growth - typically by finding and correcting sources of water or moisture

Here are photos of what is growing in my barn regarding my post below:
barn growth2.JPG
Let me know if you can open the file, there seems to be no other way to attach it, can I e mail it to you?

On 2017-05-22 by Jeannie

I have white, mushroom like substances growing on my interior barn walls. It happened after I had 12' x 72' of concrete removed and relaid. The contractor used a wet saw blade to cut out the concrete and the concrete mud created went everywhere.

There was black and white mold created inside an interior room connected to the barn and a mold specialist was called. He removed walls, wood and treated everything inside and out. He did not know what the mushroom like substances were, but treated it anyway. Several months later, the mold was not back, but the white mushroomy like substance was. It grows in what looks like waves, and is a tough, spongy material.

The mold specialist had it tested and it came back from the lab as non mold and fungal. I sprayed it with disodium octoborate tetrahydrate and that seems to slowly kill it, but the white stuff grows so fast, it is hard to keep up with it. I miss a day spraying it and it doubles in size. It is now sprouting up in all new places, having moved from the barn to the edge walls of the house. I have photos, but do now know how to attach them here.

I think effloresence, a mineral salt formed when water evaporates leaving its mineral content behind, would not be likely to appear on lighting equipment that has been in use as that equipment would usually be so hot as to stay dry.

But if the equipment has been soaked by some event or leak then I suppose such stains and salts could appear - meaning that the equipment, having been wet, is unsafe to use.

I'd need to see the pattern and markings and also the environment to have more of a guess.

On 2017-04-20 by Elizabeth

Is it possible for efflorescence to grow on lighting equipment? At my work, some of the stage lighting is having a weird growth on the set screws and safety cables of the stage lights that looks a lot like efflorenscence. If not efflorescence, do you have an idea of what it could possibly be?

I suspect you are seeing a chemical salt residue of the "mildew" additive.
Speaking more accurately, there is no mildew in buildings: mildew is a specific family of molds that grow only on living plants.

Polyurathane mixed with m1 mildew additive was applied to wood ceiling of long home. Shortly there after white crystals appeared. Any suggestions

I agree that it's difficult to find an exact leak source without demolition when cabinets block access. You might try

- pulling the dishwasher kickplate and looking below it for leaks

- turning off water to the suspect dishwasher to see if the moist areas dry out

- look for the routing of water supply piping to enable guessing about leaks from that source - ie if no pipes run through the area then water is entering it from above or from one side.

But if it were my house I'd pull off the cabinet kickplate and inspect below. I suspect you'll find so much mold on the cabinet undersides (and thus suspect mold on their back walls) that you'll end up having to remove the cabinetry to clean and remove mold.

On 2017-02-15 by Betty

Exterior red brick has white deposits, roughly where lower kitchen cabinets are on inside of house. Below cabinets where toe area is, there are two places with black substance, probably mold of some kind. One place the wood looks buckled where black stuff grew between wood and veneer.

This part of the cabinet has dishwasher and sink. How would I find leaking water source without removing about ten feet of lower cabinet? Thank you very much for your time and your website.

Could the material be corroding?

On 2017-01-16 by Monika

I Was cleaning out a salt shaker I bought at a thrift shop. The next morning it was covered with a white powder substance. I thought maybe a salt residue? I cleaned it with soap and water kept it out to dry and the next day it was covered again. Since then I have cleaned it 3 more times with dish soap and very hot water. Within minutes you can see white crystals forming. What is going on?

On 2016-11-09 by (mod) -

Anon:

Find and fix the moisture source.

Drying time may take a month or more depending on the location of the effloresence.

Simply wipe away or vacuum away. Using water based cleaners or a cleaner with vinegar to help dissolve the mineral salts is harmless but will prolong the dryout time.

how to get rid of efflorescence

On 2016-10-31 by (mod) -

You can use plain water, or for deeper stains, dilute muriatic acid, to remove effloresence. If your cleaners did absolutely nothing I'm suspicious that the stain may be white paint or paint pigment rather than efflorssence,

On 2016-10-30 by How can I 'temporarily' remove white efflourescence?

...from an exterior brick chimney surface... Bleach? Muiratic acid did absolutely nothing.

On 2016-10-21 by (mod) -

Yes it could, particularly if there is moisture below the slab and the plastic chair mat is serving as a moisture barrier in that immediate area.

White powdery substance can also be from a deteriorating carpet backer or padding.

On 2016-10-19 by Ralph

We have 2 desks with chair mats on the carpeted floor that has a white powdery substance on floor side between the plastic mat and the wood mat; floor is carpet and pad over concrete.
Six months ago we purchased finished slated wood chair mats that, unfortunately, were not adequate weight bearers,

we then placed plastic chair mats on top of them and now 6 months later we find the white powdery between the wood and plastic in the center area and gradually diminishing toward the edges. The center area appears to be damp. Could this be mold or efflorescence?

On 2016-10-19 by (mod) -

Tony,

Since efflorescence is a mineral salt Left Behind when water has passed through masonry materials such as concrete, concrete block, or brick, finding efflorescence on a wood surface would be extremely odd

. I suppose that if water has passed through a masonry wall and then through a wood surface it might be evaporated leaving some mineral salt. However more likely is white staining or moisture damage to the wood itself that is not a mineral salt, that is, it's not efflorescence.

Please search inspectapedia.com for WHITE STAINS IN BUILDINGS to see other examples and possible causes of the white stain that you described. You can also use the page bottom contact link to send me photos.

First let's accurately diagnose what's going on with the stucco wall.
Searching InspectApedia.com for

WHITE STAINS ON STUCCO we find https://inspectapedia.com/PaintFailure/Stucco_Paint_Job_Failures.php

There you'll read that there are several causes of white bloom or blotching on a stucco exterior. The cure depends on the cause.

IF the white stains on your particular stucco are really effloresence from a water leak or high moisture you'll want to identify and fix that water source first, then clean, seal, and re-paint the stucco.

Responding to the question of how quickly efflorescence develops - We replaced a small front porch that had open steps with a larger porch that has fully enclosed steps two months ago. Today I noticed efflorescence on the crawl space wall where the new porch is.

We had extremely heavy rain recently (more than anyone has seen in 20 years) so I would say that with the correct conditions efflorescence can develop within two months.

James,
Use the page bottom CONTACT link to send me some photos of the home exterior so that I can see roof and surface drainage general conditions;

Generally digging around a foundation, unless you also install a drainage mat or geotextile drain and gravel against the foundation wall, risks actually increasing water entry as any roof spillage onto the softer backfill wants to run down and under the foundation wall and footings.

So I'd concentrate on above-ground fixes first: triple check how your roof runoff is being handled; be sure surface drainage is away not towards the home;

Clean with a HEPA vaccuming or dru wipe. Once the water source has stopped it may still take a few months fir the soils below the slab to dry out. It would be unusual for there to be any consequential level of airborne particulates from this source.

Having problems with efflorescence had a leak on the outside faucet connected to the garage started noticing white powdery stuff coming up through the concrete! Have fixed the leak about 2weeks ago cleaned up the mess in the garage just by sweeping but now I'm still finding it on the concrete in the garage!

What should I do to get rid of it? Is it harmful to breath in or for my cats that sometimes sleep in the garage?

On 2014-11-07 by (mod) -

The fuzz is a mineral salt. It indicates that water or at least moisture is still migrating out of (probably through) the foundation wall.

On 2014-11-07 by allise

Thanks Dan. I'll post as the project does or does not advance. I think your idea to leave the areas un-coated after scrap off and wait over the winter to see what happens. The white fuzz looks kinda scary, though. Once I've scraped, the flat white salt beneath the elastomeric paint was one thing. The white fuzz trailing over the face of the foundation for all the neighbors to see is another, lol.

On 2014-11-07 by (mod) -

It may make most sense to clean as much as you can and leave the wall un-coated to see where moisture shows up.

On 2014-11-07 by Anonymous

Hi Dan, Yep, the water damage expert was just here a few minutes ago (Paul Davis franchise). All is bone dry everywhere under my home, below and in the attic too. Fellow says my home is very well built and very well maintained.

He will do the HVAC for us if our painter doesn't have the capability, to prep the wall areas for UGL brand waterproofing paint that is hydrostatic. My big question is: Do I paint the entire run of the foundation with the UGL hydrostatic paint, even in areas where I can't get the elastomeric off the wall?

Or do I jett the wall with power water spray (done by a very skilled jetter person) next summer, and do all the painting in the summer after the concrete drys out (dry here in Reno, except in the winter...)
--

I guess the big question in my mind is can the wall be left bare over the winter, with the exposed concrete that is actively efflorescening (with some pocking and loss to the concrete already, especially at the interface with the show porch).

The Paul Davis guy wants me to tell him how it all goes, as he cannot figure out why only the exterior is doing this, and there is NO water trail to point at anywhere. Dry Dry Dry.

On 2014-11-06 by (mod) -

Allise

Indeed the physical forces exerted by mineral salts left as moisture evaporates from a surface can be quite strong and will certainly bubble most coatings - a more porous coating such as a latex paint works a bit better.

I'd look further at the walls using a moisture meter to see if it's possible to track the moisture pattern and relate that to a possible water source.

On 2014-11-06 by allise

Hi Guys. Thanks for all this. I've got efflorescence on exterior concrete foundation walls. I see other homes in my neighborhood have similar stuff, and especially at the show porch foundation area. I suspect the show porch could have used some interface moisture barrier before it was poured.

Our trouble started a few years after the foundation was spray painted with a thick in spots layer of elatomeric paint (over what is probably a thin coat of paint done at the time the home was built). Home built in 2000.

The garage shows the foundation wall inside is dry and free of any matter, then just go to the exterior of the garage foundation wall, and there is the efflorescence. The white crystalline stuff shows mostly in areas that are sunny and have flat concrete nearby (driveway and stoop areas, or the porch).

So Far: I've scraped and removed all paint areas that bubbled up and beyond. No way I can remove all the paint (without jetted water pressure, which I don't think you are going to recomment, right?)

My Plan: Remove as much paint, vacumn (HEPA), paint with UGL paint, finish with a thing latex paint to match the color of the rest of the paint I can't get off.

My Concerns: The pressure to release/evaporate will then move to begin bubbling in new areas where the elastomeric paint remains, and I'll have to keep at this. This is my best outcome, as this is doable. Right?

I've looked for water sources and have cut plantings out, moved trash can away from side of home, eliminated drip lines from plantings in front of show porch. Long ago I removed all the turf lawn from my front yard, and have only dripped drought tolerent plantings, but left the irrigation for the lawn in place and do use it on occasion. I've had a moisture expert come look under my home for water leaks.

None. I've had a moisture barrier placed in 'tight' fashion under my home two years ago. Not as tight as for radon, but comprehensive. Is this good or is this bad?

We live in a dry environment (Reno Nevada) thatdoes get downpours.
Gutters good.

On 2014-10-19 by (mod) -

Vaccuming may be best. If you need to wash the surface keep in mind that wetting may generate a bit more of these mineral salts requiring a follow-up cleanoff.

I have a poured concrete room 16 foot long by four foot in our basement.It is directly below a 16 foot brick lined flower bed which is located outside and in front of our home.

Before we bought the home the gutters needed to be replaced so water was constantly dripping into the flower bed ,down the inside wall of the flower bed and making it way into the basement room. Now I have new gutters

so I haven't seen water in the room but I am left with the junk(EFFL) on the wall. Maybe some mold mixed in. How should I clean the stuff off? Thank you for your help. Tom

Question: 2 weeks ago we had a roof leak. It left a wet spot on the ceiling about 3 'x3' in size. We scraped off some of the peeling paint which exposed the plaster. Which I believe it is plasterboard. I was checking the moisture readings last night and it seems to be going down a little.

e have had a dehumidifier in the room since we noticed the spot, but it's taking so long to dry. Anyway, today when I went in to check the moisture readings, there was something growing on the patch where we exposed the plaster. The best way I can explain it, is that it looked like patches of flour. What is this? Thanks!
