Correcting a sloped shower mortar bed

[jakeblade]

OK here we go.
I just installed the mortar and sloped it for my shower pan that will be using the PVC material. This is the first sloped portion that the PVC materail will go over.

Unfortunately this was the first time I ever attempted this and have a not quite evenly sloped motor bed now. I have some dips and valleys.

The million dollar question is can I correct this without having to start over and remove what I have already done.
I was thinking that I could use a thinset to get rid of the valleys and dips to and get the nice even slope that I had intended in the first place. The mfg of the mortar does not recomend adding a new layer of Mortar so that is how I came to the conclusion of using a thinset.

I look forward to any Professional advise that I can get a this point.

Hi Jake, Welcome.

You can use just about anything, including thin set, to patch the dips. Any kind of patching plaster or cement patch will work. What you are looking for is a reasonably solid and smooth surface on which to lay the liner. The "pre-slope" doesn't have to be waterproof or bulletproof either.

Thanks for the quick response.
I am glad to hear that I can make the correction with thinset instead of having to rip it all out!!!
I only have about 4 or 5 dips or valleys so the correction should go quickly and easily.
