The marble is dark green. We will be sure to do a second coat but how long do we have to wait before we tile?

Overnight with redgard. Be a bit careful no to poke through it with tools while setting.

For green marble an epoxy based mortar should be used.

Okay I have two different answers for the thinset. One person- I forget who-said that since its only 2x2 tile that versabond would be okay and that there would be very little chance for warping since they are so small. Can someone either verify that or is epoxy the only way to go?

Also we did the curb today and it didnt really turn out as good as we had hoped. Its pretty ugly actually! It doesnt seem to want to hang on to the mesh. Did we not use enough water or what and will it be okay? Should i spray some water on it with a water bottle? hopefully all is well and tiling is next but we will wait for a reply from the pros-thats you guys! Thanks to all as usual!!

I have a question about my mortar bed. Since it has taken us so long to do the tiling the mortar bed has been walked on etc. etc. needless to say I can see the membrane. My questions are 1. how do i get up the rest of the mortar bed and 2. is there a way to fix it or just start over? Thanks

If you're able to, post a pic of the curb. We can tell you if it's fixable or needs to be torn out.

As for the mud bed, if you can see the liner, I'd say it needs to come out. How thick was it at the drain?

Jill,

How on earth can that be? The deck mud should have been about 1 1/2" or thicker. You're saying you walked it off? Why was it not covered with cardboard or ply? Never mind.

A picture would help. Either a link or by email.

Well Jaz what happened was someone put a step stool in the shower and stood on it . It was covered with a moving blanket but the foot of the step stool poked a hole in the mud. Then I started to sweep

The mud is about 1/2 inch at the drain

OK, trying to remember what's going on without reading all this again.

You have a pre-slope right, and no problems. Then you installed the drain and membrane. You then installed a vapor barrier on the studs, the CBU or (?) on the walls. You then placed the mud deck, which is only 1/2" at the drain and it is now damaged? And the curb is not right?

OK, start over with new deck mud, then build the curb again. What type of mix did you use for the deck mud, and for the curb?

Jaz

Hi Jaz Yes we did everything like you said, the preslope is fine along with the waterproofing. As far as the curb goes, it didn't look pretty but I leveled it out with thinset and I think it's fine. My question is, since we have to redo the deck mud do we also have to redo the curb? We used mortar mix for the curb.

As far as the deck mud we used the calculator we found online that calls for 133lbs of sand topping mix and 67lbs. of coarse sand. Does that sound right to you? We are going to home depot today but will wait for your advice.

thanks again
