Liquid adhesive for EPDM shower pan?

[Bucho]

I want to use EPDM for my shower pan, because I have a whole roll of the stuff that I use for pond liners. Normally, I use the splice tape to join pieces. However, I don't think the splice tape is ideal for corner reinforcing a shower pan.

What type of liquid adhesive works well for EPDM, and where do I obtain it?

Thank you.

Hi Bucho,

Not as far as I'm concerned. They make it for ponds which don't suffer if they seep a bit. The stuff is not specified for shower liners. Besides, a piece of approved liner is not that expensive.

But it is approved for roofing. Still a no?

OK I cannt help myself--It is not approved for showers ,will not meet the standards,will not hold up under a mortar bed. EPDM buried under cement (mortar) will fail!If you don't want to hear it from me ask Gobis!

Eric's company makes a couple of the approved shower pan liners. Check out the link under his name.

Hey, I'm the king of hack jobs, and have been specializing in hack shortcuts for decades. I've even used torch on roofing for shower pans--of course without a pre-slope. But that was before I came here.

That being said, some questions you want to ask yourself is whether the product has an anti-mold and anti-fugus additive. Most shower pans do, most roofing products dont.

I also think you'll find the the EDPM is not as flexible as shower grade pvc and cpe, and that folding corners will be a pain.

Finally is the issue of the dam corners. Have you thought about what you are going to use? I sure as heck wouldn't try to get cpe corner dams to stick to EDPM.

If this is a customer's home and you feel lucky, go for it.

If this is your home and you intend to reside there for more than 5-10 years, I'd use a product which is designed for the shower. They call this a shower pan. Leave the roofing products on the roof.

Just thought that I'd ask.

I can take advice well enough. If it doesn't seem like the right thing to do, it probably isn't...
