View Full Version : Levelquik RS not drying

Hi Tile wizards. I mixed up some levelquik RS to lean up some chips and inconsistencies in my bathroom before laying tile. Its been 2 hours and it's still not quite dry.

The smaller bathroom was about a 1/8 inch pour. It was reasonably hard when I went back to check on it just now.

The bigger bathroom was laid a little thicker, around 3/8" and is somewhat hard but will come up the consistency of soft eraser dust if you run your fingers across the top of it.

Any ideas about what to do from here? Let it dry more? Take it up and start over? It's been rainy here but still very hot 90s and 100s so I can't imagine it would take so long to dry off.

Maybe the SLC was old. Regardless, I would let it dry longer. Did you use a primer?

Yep I did. Cleaned, swept, mopped, and primed with customs leveler. I talked to rep at custom and he said that it could have been either too much water (which I guarantee is not the case. I measured exactly.) Or it could have been not mixed well enough. He said that it must be mixed at over 600 RPM and I have serious doubts that I mixed it with that high RPM. The bucket was so full, idk how anyone could mix over 600rpm in a 5 Gallon bucket.

my bet is it set up fine.

Just did a level with the RS leveler and the HO added too much water to the mix...an extra 1/2 gallon and it was pretty loose.....however, it firmed up well...although it took an extra 12 hours to do so. Still, it hardened up fine with the help of a fan.

Weird. It's still not set. I can run my fingers over the top and it feels like clay. I'm getting close to just taking it up and starting over.

Was this from an opened bag? In really humid weather the stuff can go bad quickly in an opened bag.

FWIW, the stuff cures, not dries. It’s a chemical reaction. It will get hard before it is totally dry.

Interesting. Now that you mention it, there was a small hole in the second bag which is the floor that wouldn't dry. I wonder if that's what happened.

I rented a demo hammer last night and took the whole floor up. I'll prime it tonight and pour it again tomorrow.

I also think it wasn't mixed as well as it should have been because I kept having to stop the drill to keep the LQ from splashing out of the bucket and it definitely wasn't mixed over 600rpm. It mixed to liquid with no lumps or bubbles but wonder if the chemical reaction didnt take effect or if the open bad was the culprit.

After 4 days the other bathroom is finally hardening (the unopened bag #1) and was poured a lot thinner @ 1/16"

Thanks for all the input fellas.

Another thing you may encounter is just stuff past it’s expiratio date, which is only valid in an undamaged bag stored properly.The stuff may not become a solid lump in a compromised bag, but end up a bunch of loosely attached, cured grains that can be broken up. When mixing, you’ve got essentially all aggregate with no active cement left to cure. Cement cures just fine while wet. Curing actually chemically incorporates water into its structure...the excess not needed for that reaction will eventually dry.

Too much water, and the stuff can separate the particles making the crystalline structure have less chance of interlocking, and allow the active and inactive components to separate, sort of like panning for gold.

Thanks for the input. Ive just laid it for the 2nd time and it was night and day. I bought a smaller paddle for the mixer so it could rotate faster. I also turned on the AC in the unit so that it can stay cool and dry. It could have been mixed badly the first time, been a bad batch, or both but this pour was 100x better. https://uploads.tapatalk-cdn.com/20190704/07c6c2f8312c99f02ead9933b6e38090.jpg

Lol seriously. 2 floors later, if it doesn't, I'm installing carpet in the bathroom.

Night and day. It was dry in 3 hours, I'm tiling on it today.

Question for floor tile pros: There was a tiny (less than 1/16") border where the first batch of LQ met with the 2nd. The floor is smooth as glass and level, except for this small piece. Do I need to address it somehow or can I just start tiling.

With it that small, I should think you're good to go. Any more than that, a rub stone would even it out.

What Laz said but if you don't have a rub stone, wrap a piece of sand paper around a block of wood and use that.

It's tiny but it wouldn't hurt to give it a pass with some sandpaper. Low grit?

I'd say more of a medium grit. It won't take much to sand down. Then sweep and sponge it.

Here's a pic of the (mostly) finished result.

Huge thanks to the guys on this thread who have been super helpful with knowledge and advice. If not for this forum, I would not have known that the first contractor who did my shower pan royally effed it up and I'd have had to rip it out and do it again in the near future. Johns ebook was also a clutch resource, well worth the money.

I learned a ton about renovation in general thanks to the forums and stickies. It gave me the confidence to do more than I could have afforded to if I contracted out the work.

Cheers to this forum and this community.https://uploads.tapatalk-cdn.com/20190706/a0adccbeecb1f9535fa5ae50a839852d.jpg
