Mapei WP 200 waterproofing and uncoupling membrane

[Italy]

Some people like Latex though Antonio.
I hear that many Germans are fond of latex?

I do not know, I use it only in exceptional cases.
when use of grout rubbish, I add a bit of latex as a precaution.

Brown paper would uncouple!
Honestly, don't get all hung up on marketing.

My understanding is this - loads of different products will do loads of different jobs, many of which they aren't "meant" for, and in many cases it's just because the manufacturer hasn't paid for the required testing, or they don't want product A to reduce sales of their product B...

So, as you've seen it in the flesh, would you put it on par with tm's mat or brown paper for decoupling?

Well I've yet to use brown paper, but I didn't like tm membrane, I found it tricky to apply. I know it's not classed as waterproof, the fleece will transport water. But I suspect it's far more stretchy than the mapei.
I Normally Stick with ditra for uncoupling, because it's so far advanced of anything else, but waterproofing I believe there's more of a level playing field in terms of choice and function.

Have any of you used Ardex DS 20 for uncoupling?

 

[J Sid]

no, you?

Not yet but was considering it, I just wanted to see if there were any opinions on it out there. I can't think of a bad product that Ardex make.

Have I just misread the pdf or do you have to use epoxy or grout with additive on this stuff? If so why?

Hi, it should be a CG2 or epoxy. Ultracolor Plus or Kerapoxy ok as is all our grouts.
