You sure dont see much hot mop on commercial jobs!! :whistling
16 sq.ft.pan (only) $40.00 vs. $250.00..money in your pocket :thumbup:
single ply roof vs hot mop :thumbsup:
Well you're already calling in a separate guy to mop the pan why not another guy to tile the shower. If you work it right you could pay out the cost of the shower to your subs over 5 or 6 subs and a few weeks thereby extending your working capital on that job. Just sounds like good biz to me. :laughing:
specialty trades like waterproofers are worth their weight in gold. multiple layers of asphalt saturated felt are welded together by hot asphalt (what a concept) then topped off by a thick coating of the same material. when cooled, inside corners remain flexible, ASTM felt seals itself around mechanical fasteners (firring nails or staples) and the durable topper holds water like a swimming pool and resists damage.
just some of the reasons hot mopped shower pans are better than single sheet vinyl liners (imo).

Unbelievable....someone posted a legitimate response to the question.
Way to go!
Plbg. Code calls out for a flood test ,rrguardless of what the pan is made from..
Almost all commercial work im involved with does. (Flood test.) never seen hot mop used in commercial work.
PVC ,CPE,and all the various ANSI 118.10 surface applied are the norm.
Years ago lead,but that was coaded with a cold tar and in NY. City.
Down in Austin TX. Theres a bit of fiberglass used.Copper still shows up in some spec,s in new england but not on the job. Hot Mop is a CA. Thing.
Hot mopping has been the timeless standard for shower pan water proofing for 60 years.. nothing better. If you dont know why then why speak of it like its just a west coast thing. Pan liner , schluter , wedi systems are inferior. but the have big money puching them . none of them have sstood the test of time. Hot mops will last for decades if not reused. I E. demo then go over it. The tile setting trade is a specialized trade, with knowledge of all parts of intallation. DIY'ers and handymen dont get the subtrates and waterproofing right almost 100% of the time. jsut besase one can set tile dosent mean it a good job. and he will not be back to fix it..! gaurateed.!
I'm not sure why you are popping in with your first post on an old thread with such a statement. People are speaking of it as a Southwest/West coast/California thing, because that is primarily the only place hot mopping is done anymore.
Where's you evidence that properly installed "Pan liner, Schluter , Wedi systems are inferior...none of them have sstood the test of time"? Are you StarrTile, the tiling expert from YouTube?
The only thing correct you said is that "The tile setting trade is a specialized trade, with knowledge of all parts of intallation." I, personally, would not speak in absolutes and prefer to say that OFTEN DIY'ers and even professionals get waterproofing details wrong.
You like hot mopping and that is great. If there is still use and demand in your area, go for it? I'm sure there is still a niche market, just like buggy whips. I don't think you are going to convince people to go back as they have mostly moved on or it was never a thing in their area.
By the way, all of those red squiggles are incorrect spelling. Is that the long term effects of hot mopping?
pros of hot mop: its slightly better at being leak proof
cons of hot mop: smells bad for like 1-3 days in the house, not good for jobs sites that are condos, apts..etc... i think it takes longer to set up then the liners....
i dont think it matters if you choose liners from THD or schulter etc... They both get the job done, both about the same cost (hot mop service in Los Angeles is about $280-$400 depends how big the shower pan is)
i say go w the liner because the smell is annoying and can give you a headache.
Just ripped out a hot-mop that had failed. Hot mops are not good for earthquake country since it turns brittle and rips at the folds during a quake. Vinyl is the way to go.
Hot mops are the time tested industry standard guaranteed for decades and done by a licensed waterproofing company.. as where liners need someone that is well versed at them ..takes many installs to get all the nuances down ..like cutting it properly, pre-sloping BEFORE THE LINER GOES IN, folding corners properly and tight, stapling correctly, making sure weep holes are clear..etc. I personally have seen to many newfangled products fail over time. Gold bond slip sheet for one. Red guard has been labeled a do it all and its junk . No good for water proofing anyway. Doesn't have any adhesion. So GO with Hot mops they are capable of being walked on in two hours after install. Yes they smell for a while , but not toxic.
