- Our experts will show you what causes efflorescence and how to remove and prevent it.
As the hot and humid weather continues, so do the complaints about efflorescence. Marcel Schoen of LATICRETE Technical Services shares causes, prevention and removal information.
The best ways to help minimize the occurrence of efflorescence are:
1. Use a polymer fortified thin-set like 254 Platinum, 257 TITANIUM™ or MULTIMAX™ LITE from LATICRETE
2. Use a calcium aluminate cement based grout such as: PERMACOLOR® Select, PERMACOLOR Grout, or PERMACOLOR Select NS
3. Slope the area to evacuate water from the surface to the sides of the installation - if most of the moisture moves away from the slab then there is less of a chance for efflorescence to occur.
4. For exterior installations over occupied space, use of the Plaza and Deck System (cdn.laticrete.com/~/media/pro.... This system prevents much of the moisture from staying in the mortar bed as it allows for runoff of water that gets beneath or into the
mortar bed.

Hey, thanks for sharing so much beneficial information!
I just get the wall which kitchen cabinets are going to be applied on tiled and grouted. The tiler did just wait for 10 minutes after tiling and then grouted immediately. I learned out that tile adhesive needs 24 hours for walls and 48 hours for ground to dry. I've read that applying the grouting too soon might cause efflorescence. But at the same time efflorescence examples I saw are either outdoor areas or bathrooms, never seen a kitchen wall with that issue on the internet. The tiler said "trust me, there won't be any problem" but I do not trust him at all after all. Should I be expecting any problems? Perhaps I need to apply sealant?
Thanks for the question. The result can go either way. On one hand there may not be an issue that arise. On the other and more common, grouting too soon can yield a number of issues including: Breaking the bond of the thinset to the tiles, Color or shading issues, weak or soft grout, minor cracks in the grout, and yes even efflorescence if soluble salts are present in the mortar/grout.
We always recommend following the written instruction of the adhesive to see how much time has to pass prior to grouting.
Typically a 24hour time frame is suggested but this can be shortened down to around 4 hours if using a rapid setting product.
One foundation wall of our house is on a downslope that has been permeated by water for many years. Want to avoid digging up the front yard to reseal the outside portion of the wall. If we thoroughly scrub the inside wall, is there a recommended treatment paint that will reduce or contain the efflorescence? Can such paint be coloured?
We do not sell a product for this purpose. You'd have to do some research to see what paints are available for this. Possibly DRYLOK may have something that can help you.
Put plastic sheet below the cement before pouring. Both on foundations and floors. Use a sulphate resistant type 5 cement. In freezing environments specify air entrained concrete to prevent spalling of surface. In tropical areas have redimix add fillers to build waterproofing into the cement. Keep fresh concrete damp for 15 to 30 days after a pour.
All good points Ken!
you all probably dont give a shit but does any of you know of a trick to get back into an Instagram account?
I somehow lost the login password. I appreciate any tricks you can offer me
@Kamryn Kian instablaster =)
@Ralph Orlando I really appreciate your reply. I got to the site thru google and I'm in the hacking process atm.
Seems to take a while so I will reply here later when my account password hopefully is recovered.
@Ralph Orlando It worked and I actually got access to my account again. I am so happy!
Thanks so much, you saved my ass !

Good information. However, does efflorescence cause structural damage? Would this cause damage to a subterranean parking structure?
Hi Joe. Thank you for your message. Since there are lots of semantics involved in your question, we suggest reaching out to our tech support team directly, so they can get you the exact information that you need. You can call at 800.243.4788 x1235, email us at technicalservices@laticrete.com. Hope this helps!
Just removed laminate flooring that was installed 15 years ago on top of my stained concrete floors. Found major efflorescense - hand sanded it off and also used white pad with floor sander. A few days later it's already coming back. What do you suggest to remove it with?
Hi Todd. Thank you for watching. You can try and seal the concrete, but unfortunately as long as there are soluble salts within that slab being driven up by moisture, it'll keep happening until it runs out. Sealing the concrete may mitigate the issue, but it probably won't stop it completely. You can also try to mitigate the moisture to figure out where it's coming from. Hope this helps!
@@laticrete I have the same issue as @ToddPenrod ...
if left alone and all 3 components are still present what will eventually happen ?
Radon Sealer. Can paint over it also
Thanks. That was very helpful. What product/method is recommended for shower tile? Also, will efflorescence buildup harm or block shower drains?
We've never seen a case where this would clog a drain. For recommendations on your particular project, we'd recommend calling our Technical Services Department so that they may understand the specifics of your project. They can be reached at 1.800.243.4788 x1235.
The maker of this video should see the difference between elimination and prevention.

@@laticrete hi I just painted my walls black and I have efflorescence how do I get rid of it
What wasn't helpful about it? I thought it was a pretty informative video and I'm a 20+ year tile veteran not just a diy homeowner looking for answers
