I have spent the last few days doing a lot of online research and have come across some chatter or internet hype about a new anti fracture membrane by Devcom called GreenSkin. I have now been researching this new material and lots of miss information is being shared online in regards to this new product called Green Skin. Make sure you read this complete thread since the info has been edited to include my most latest findings.
As of July 6, 2013 GreenSkin is NOT an approved waterproofing material - what I find alarming is so many appear to be treating it like one. I hope the men who jumped on the band wagon of using their promotional rolls do not have any series failures to fix down the road.
When the product was launched it appears they tried to start a contest for contractors but pulled the plug. I'm assuming that dozens and dozens of the regualr posters on John Bridge tile forum where sent promotional rolls to play with and use at work. I have seen dozens of action shots and many pictures of tile men using the product outside of TCNA and TTMAC specifications. The TCNA and the TTMAC require any waterproofing membrane to have a ANSI 118.10 approval rating. GreenSkin does not have this.
Reading the data sheet I noticed that it claims to be "Anti Wicking". I'm not sure if this is a good thing or a bad thing but it is very interesting. My experience is that all these sheet membranes wick. Years back I feared this was a bad thing but in hindsight I find that the wicking actually spreads the moisture in a shower floor or wall over a large area and helps the room dry out quicker. This is marginal of course and I have never measure the two head to head.
I'm going to order a roll of this product (unless someone State Side can send me 10 square feet)
UPDATE: Testing Started Already!!!
and put GreenSkin on the rack and test it along side the other anti fracture membranes I'm testing and uncoupling systems. We have been buried with work trying to finish of this hallway renovation but will have more time this week to continue the testing of my uncoupling systems.
I'll gather up some pictures of GreenSkin and have some descriptions here. Jim did Schluter discuss this new membrane at your training class with them?
