## Description

Product Description          GreenSkin GS-4000CSI, is a state-of-the-art, 100% clean & green, super-sticky, crack isolation flooring underlayment. This cutting edge anti-fracture membrane just happens to tout TCNA's highest performance crack strength level available on the market (ANSI 118). GreenSkin's hi-tech approach, inverts the structure, as well as the traditional VOC/solvent based asphalt mind-set, by adding enormous strength and performance features to the membrane, while actually upgrading the glue strength/chemistry, to a PRIMERLESS, crystal clear, clean and green PSA / hot melt - eliminating toxins from the air you breath (i.e. asphalt based designs off-gas VOC/solvents). This design allows us to build in a moisture management ply of metallized polyester (METPET � looks like foil), add a clean & green anti-microbial agent to the topside nonwoven, and thus, provide you with a �beefed up,� water tight, non-wicking, high energy surface, with which to receive your desired thin set formulation. The best part of all of this, is that GreenSkin membrane is VERY price competitive ($/SF).             From the Manufacturer          GreenSkin GS-4000CSI Crack Suppression Isolation Membrane; 100% Clean and Green Primerless Peel & Stick Underlayment; Water Tight Moisture Management Anti-Fracture Crack Iso Membrane

### ⭐⭐⭐ 3.0 out of 5 stars







  
  
    The silver backing is SUPER tacky. Hard to even get your fingers off ...
  

*by S***M on Reviewed in the United States on October 19, 2016*

What I received was not "green" - it was "white"??  Appeared to be the same otherwise so I used it anyway - time will tell if hair line cracks show up in the new tile.  Be sure NOT to get the paper backing wet.  If it gets wet you won't get the paper off.  The silver backing is SUPER tacky.  Hard to even get your fingers off of it.  It should absolutely stay stuck to the concrete.  Hope the thin set stays stuck to the "White Skin" fabric!  Again time will tell.

    Great product
  

*by M***N on Reviewed in the United States on October 7, 2015*

I am tiling several rooms that used to have carpet. My house is on a slab foundation and I noticed a lot of cracks in the slab. At a previous house I lived in I tiled over the cracks and later regretted it because the tile cracked over the cracks in the slab. A few years ago I used a similar product to this and had good results. That product was more difficult to use because it required a bad smelling primer to be applied prior to the membrane. I love using this GreenSkin because it has a peel off backing and requires no primer. I apply it directly over any cracks in the slab and then use a crack resisting thinset mortar. It is easy to cut with a utility knife of a pair of scissors.  So far I have had good results.

I also received the "White" product. It is NOT the same. It does not have the green microbial top layer or the "Foil" layer. Useless product IMO.
