Hi guys!

[Albertus Magnus]

Hi guys. The name's Magnus. My friends use to call me that so that's what I'm using here.

My avatar is a pic of a burger from "In-and-Out Burger."
To me, it's like a Johnny Rocket's Burger, only it doesn't cost as much lol.

Anyway, here's my problem. I've got the durock installed and the waterproofing rolled on. Afterwards, I took a straight edge to the wall (it's 8' high) and found that it curves into a very shallow "S."

At the two points where it curves on the "S," the deflection measures around 3/16."

Should I be worried about that? I was thinking that I should fill it in with a slurry mix made with 254? Or even a thinset since it's on a vertical surface and the slurry might sag and fall off the wall.

Here's a drawing I made of the problem. As you can see, the deflection is very small.

Hello,

The burger looks yummy What size tile are you planning to use?

[Davy]

A slurry sounds thin. I would make it just a little thinner than usual but not what I'd call a slurry. You can do some floating out, just use some sort of straight edge to rake across the mud to pull any extra off the wall.

What Davy said. Just get some thinset over the low area and rake it off with a straight edge. Just use the thinset your planning to set with. No need to be mixing materials. The thinset doesnt need to be any more loose than normal. Just get it up there and rake it off. Your fortunate the dip is in the middle. Its the ends out of wack that are hard.

okey dokey. After it dries a little, I'll scratch it so maybe the second coat of thinset will stick better. Thanks guys. I was kind of worried for a second.

What's up Handy??

I'm going to use 3x6.

yeah. I was thinking the slurry might just fall off. Thanks for the tip about floating out.

I was just thinking if it was a large format tile you could work it out with the thinset but screeding some across sounds optimal.

Welcome, Magnus.

If you'll visit our FAQ in the dark blue bar near the top of the page you'll find a brief tutorial on how to properly attribute quotes you post here on the forums. Very simple once you see it.

This is just a "quote test" to see if I can quote correctly

I did it! Thanks CX!

I have a question.

Let's say I use a ledger underneath my tiles to get them started.

When is it safe to pull the ledger out?

[Davy]

Best to wait till the next day. Some times we will need to pull the board within 6 to 8 hours but we have to be careful not the break loose any tiles. In other words, the tiles may not slide but they will easily break bond.

I used some 4XLT today but I couldn't get it flat.

It seemed pretty sticky and everytime I used the thin side of my 6' Stabila level to flatten it out I pulled the medium-set off the wall a little bit. I tried to trowel it flat but no success.



Can anyone recommend a good thin-set that isn't so sticky?

Maybe my problem was using medium-set but if I use the recipe to make thinset out of the 4XLT (6 quarts instead of 5 1/4 quarts of water per bag) it might still be too sticky.

Next time I will also use 1"X4"X6' lumber instead of my Stabila level to float out. That was pretty retarded. I think I almost ruined my level.

For what you're trying to do, I love using Ardex Feather Finish. I use it to patch low spots all the time. I have no idea if you could find it locally but thought I'd through the idea out there.
