retile rough mortar shower pan

Hi, my name is Allen and I have a 3 by 4 mortar shower pan with the tiles removed. The mortar is rough and has craters in it. Can I top off the entire mortar bed with thinset as long as it is not thicker than 1/4 of an inch to smooth it out and let it dry, than rethinset and put my new 2 by 2 tile on it? All Help is very much appreciated. Thank You.

Welcome to the forums! The road at the end of my driveway is "rough", just how rough is your floor? Can you post some pictures so we can see just how rough it is? No close ups, as we know what concrete looks like.

More important is whats under the mud bed. How old is the shower pan? Do you know how it was constructed? Does it have a proper preslope under the liner? What is condition of the existing drain? Shower pans have a useful life, and eventually they fail. If yours is old, it might be time to demo it and rebuild a new one.

If you have already considered what I said, and have determined that all is ok, you may be able to do what you describe. Is the mud bed in tact, or is it cracked and crumbly? Did you demo the walls as well? If you can tell us a little more about the project it will be helpful.

Thinset on shower floor?

Is thinset a good idea for the shower floor? Should something more substantial be used? Will porcelain tile mortar work better than thinset?

Also, I have a question about wall seams in the shower...

Is there a significant or serious problem with getting thinset into the seam of an outside corner? On another forum site an expert recommended not using thinset for outside corner seams because the two surfaces will generally move, he recommended silicon caulk prior to applying thinset to the surface seams and inside corners, the idea was that the caulk will fill the void and prevent thinset from entering the seam. I wanted to reply and discuss when they asked me for $ 9.95. I said, "I don't think so".
