How to pre slope a shower pan on slab - Using Dry Pack Mortar

I this video I will demonstrate how to pre-slope shower pan on slab. Pre slope pan provides gradual slope for rubber pan liner. If you don't want to have a large wet spot around your shower drain you better build a pre-slope pan under your shower pan liner.

You're doing amazing Tile work. Waterproofing is definitely your expertise.

[@simonproatl]

Thanks 👍

[@user-pu4uh6do2z]

Wow, I wish I could find a contractor in my area that is as thorough as you.

[@simonproatl]

You can do it! :)

[@rebeccaskeldon1064]

THANK YOU for making this video, it’s so helpful and specific for my project.

[@simonproatl]

I'm glad that it was helpful.

[@Renatousa17]

[@simonproatl]

Glad it helped

Don't call that sponge "dumb" 😂

Very helpful. I hadn't thought of painting on waterproofing before the PVC liner, but it makes sense. I have plenty of Redgard so might as well. A couple questions:
Do you need to use adhesive between that preslope and the PVC liner? And do you allow any drying/curing time for each layer before doing the next?

[@simonproatl]

You need silicone around the drain between preslope and liner. It's better to wait till every layer dries.

Your video is great content, i like it. I have question though. How long does it take the dry pack to set before i can continue working? Thank you.

[@simonproatl]

I usually wait till next day.

[@EJfromNYC]

homedepot is out of stock for the SAKRETE
50 lb. Floor Mud Mortar, which other one do you recommend? I like your videos, I am about to do your concrete curb this week, next is the pre slope bed... just dont know which mix to use... thanks!

[@simonproatl]

For pre-sloped pan you can use anything that has cement and sand like Sand/Topping Mix. For shower pan is better to use 4 to 1 Mud Bed Mix

Hi thanks so much for your video ! I found some fiberglass mesh but it is in rolls that are about 10” wide. Do you think I could still use it if I lay 5 lengths of the 10” strips next to each other and embed them in a thin coat Of thinset? Or do you recommend that I keep looking for one solid piece of fiberglass mesh?

[@simonproatl]

Yes. I will work.

[@laurenharper1510]

@@simonproatlthank you! Actually I went to a Brick and stone supply store and found the huge roll of fiberglass mesh. I have 3 showers to do so I decided it was worth the cost!

[@burtrussel1535]

Hi. Do you have to put a pre-slope below the dry pack? I was planning to do a dry pack pan thats sloped to a flo fx drain kit. Its going on a slab. Can i just do a sloped dry pack pan, then use the waterproof membrane, then tile? Thank you for making great video.

[@simonproatl]

When I prep the shower I will use dry pack mortar to build pre slope pan that creates slope for rubber liner. Then i will install rubber liner and build shower pan using dry pack mortar. I never used Fx drain kit.

[@JustAnAcre]

You are a refreshing channel compared to the crap that is out there.

[@simonproatl]

Thanks

[@franciscosunworld]

Great video, but I would like to know all the steps from the very begging to the end. Thanks a lot!

[@simonproatl]

Ok, thank you

[@bennisim7949]

Hi. Did you apply the waterproofing right away ? Didn’t let the mud bed to dry ? Thanks.

[@simonproatl]

It's better to wait till it dries but it will bond very well to damp surfaces.

[@laurenharper1510]

I was wondering the same thing.
I would think let each layer dry first because each different material shrinks at different rates, but that is just my opinion.

[@simplefacecard]

Can i use fiberglass cloth instead

[@simonproatl]

Yes. But it can get expensive. I used it on the shower curbs in the past. You can find large mesh in stucco supply store or on ebay.

[@gizzeconstruction]

no showerpan?

[@simonproatl]

In the future video :)
