First time with denshield.

First time using denshield in a little shower where doing. The home owner doesn't want to spend the money for a wedi or Schuler shower kit. It's a family friend so all of you know how these jobs go. I was at least going to use perma base and use aquadefense as we use to before all the nice new products. The homeowner really wants to use denshield and I'm not really familiar with it. Any info will be much appreciated. Can I use aqua defense or red guard on it or is the coating on it good enough. Thanks in advance.

Unlike some people I like to follow directions and trust the manufacturer. Mr. Werner Schluter is a very smart man and his company is a testing and research machine. Everything they make is of the highest quality.

When you apply Kerdi to a substrate, it doesn't matter much what's behind it. You can make Swiss Cheese watertight with Kerdi over it. Schluter says regular wallboard is perfect, as you know.

I've installed it over both types of wallboard, over Hardie, Durock, Permabase, and others. I've also used Kerdi Board. If the substrate is under my control, I would go with regular drywall, with Kerdi Board a close second.

Drywall doesn't belong in a shower no matter what you are putting on top of it. It is an organic material.

Just because they say it can be done, doesn't mean that it should be done.

I don't know if they reformulated redguard or what, but I've used some recently and it sure does stick to my skin (membrane).

:eek: People use cbu and cbu-ish stuff for curbs? :eek:
That seems weird to me. But I guess then people can use 2x stock and sheetrock, then just kerdi, sheet, or liquid over it.

Had pork ribs for supper tonight. Three of them fed 2 people and had leftovers. Don't see anything wrong with that at all.
I've used cbu on curbs for years. I tape all seams and fill with thinset, then kerdi or hydroban.

However, we are going to start using Wedi very soon. I've done my own crazy tests on it and like it!

When using liquid membrane, does anyone use a film gauge? Anyone have one? Do you guys just apply a coat and call it good? Talking about regular CBU now.

What's the alarm about that? You can use most CBU's on curbs as long as you apply a waterproofing membrane over them.

No comment from anyone about not burying Dens in deck mud? How many have done that?

Ah, Hey Rob...

"The idea is still solid to waterproof he entire surface of the DenShield."

"The surface is water proof except for the seams and the screw holes. Those have to be waterproofed. Sure, you can roll the dice and hope that the AD is perfect around each hole and seam, or you can roll the whole wall and never have to worry. It is a solid sheet of AD.

It's really not that difficult of a concept. It doesn't take much more time or material. And you only need one coat to do the trick.
"

...

"but since DS is already waterproofed it is not needed, IMO."
:blink:

:whistling

...so which is it?

Taken out of context, sure it looks inconsistent, however the last statement is in reference to multiple coats of AD over DS. The former statements were in regards to ensuring at least one solid coat of waterproofing.

I'll explain again. Dabbing over screws and cover the corners leaves edges that are all areas of weakness, giving at least one solid coat ensures that you have a solid sheet of waterproofing.

Since the majority of the sheet of DS already has multiple layers of waterproofing, additional coats of AD are nice but IMO not needed to ensure one solid coat of coverage.

I didn't say that Matt was wrong, just called it how I saw it, as over kill at that point.

So I choose, both ways under my intended context. :thumbsup:

When you guys have some time you should go to the GP site and read the installation manual. Read the whole thing but pay special attention to page 7 DS002. Continue to page 8 DS004 and study how they want you to do a shower seat. Notice you have to apply a waterproofing system over Dens for the seat. Item "F". Then what? Where does F stop? Ridiculous I think.

While you're scrolling down to page 13 to find the approved waterproofing systems, take a look at the other shower sketches, DS007 Makes my head spin and makes no sense to me.

Jaz,

I've fixed curbs that had denshield buried into the mudbed. Sucks up the water like.....drywall. Shocking, I know.:laughing:

I use cbd + membrane(liquid or sheet) or wedi for curbs. I haven't used a wrapped curb product like wedi curb,yet.

AquaD wants two coats min. for corners then seal main area. That's 3 coats. The first coat dries fast because it soaks in. The next coat(s) take longer. Not too bad if you have other stuff to do there.

Olzo,

As we all know the curb is usually the first sight of failure. Even old fashioned mud jobs are often not done right and that's the 1st to fail. I'm semi-retired and so I choose the jobs I wanna do. I could care less for people who's only desire is to get it done cheap. I have only done Kerdi showers since '05. There's no better method. Cheaper, faster, yes, but not better. IMO.
