What type of thinset should I use for an acrylic shower pan installation, and should the thinset cure before laying down the pan?
Having some trouble with my shower pan installation – any advice is appreciated!
I bought thick set mortar thinking my acrylic shower base was a “floating” one, but turns out it wasn’t. Now the mortar is crumbling and I need to start over.
Can’t seem to find the right thinset mortar online – it’s all the same stuff I already have. Any tips on what I should be looking for?
Also confused about whether the thinset should cure before putting down the shower base. Some DIY articles say yes, but I thought the point was for it to grip the base. Already used self-leveler on the floor, which was a mess.
Would really appreciate some help with:
A) the correct thinset for an acrylic shower base &
B) should the thinset cure before installing the shower base?Why would you let it cure?
I haven’t applied mortar to install a shower pan in more than 20 years because it tends to dry out and become crunchy. I’ve found that using two cans of triple expanding foam consistently yields great results.
I’m on the same page as ^
Thanks , I’ll definitely check this out!
If you haven’t checked out YouTube yet, now’s the perfect time. There are numerous videos demonstrating each step and the materials needed.
I checked out YouTube, where I found my initial incorrect idea. YouTube has a wide range of mortar types and techniques. So, without any experience myself or knowing anyone who does, I decided to ask here!
Maybe not the best idea for you to do on your own right now. 💁🏼♀️
Well, , that doesn’t sound too promising 🙃
But if you’re only recommending someone to check YouTube or Google, maybe it’s best not to comment at all? 🤷♀️ Unless you provide specific links or details, your comment isn’t really useful or related.
I’ve tackled much more complex DIY projects; this is just a frustrating task where I can’t seem to find helpful information.
Good luck, !
The base of my shower pan was made of foam, so I simply had to secure it in place with some glue.
Expanding foam definitely does the trick! We ended up using mortar with foam on top to fill in any gaps. Although it turned out a bit crumbly, I believe it will maintain its shape in the critical areas.
Let me think, I’ve experimented with thinset, Masonry cement, Portland cement, expanding foam…
It all depends on how you mix it.
And none of them healed before settling.
I tried out Structolite.
Start by test fitting the base. Once you begin, it’s tough to turn back.
Then, combine and spread the product with a trowel. The goal is to have a little extra (just a tiny bit!) so the base pushes it out. Make sure to fill all the gaps underneath. This way, the base will not only stay in place but also won’t droop when you step on it.
Place the base and add weight to ensure it makes contact with the subfloor on all sides. Double-check your level. NOW, allow it to set.
Big shoutout to for the thorough notes!!
