I'm not sure to stay with this product type or recommend completely discarding it. thanks Lisa Goodwin Robbins, RA, CCS, LEED ap Senior Member Username: lgoodrob Post Number: 116 Registered: 08-2004 Posted on Friday, January 14, 2011 - 08:45 am:    Anne, I've never heard of it either. But, before you devote much time to research, are you sure it was already installed? James M.

American Hydrotech is on 4specs.com under 07 5600 Fluid-Applied Roofing.

According to their technical information, the product complies with ASTM D 6083, which is recognized by the IBC for liquid-applied coatings. When I checked the standard, it is titled "Standard Specification for Liquid Applied Acrylic Coating Used in Roofing." The scope of the standard states it covers "100% acrylic elastomeric latex coating used as a protectective coating for roofs." In other words, the standard isn't for products used as roofing.

And yes, its not Hydrotech -- I have no questions about that product at all. its Hydrostop. as for its having a web site -- a lot of the products sold on late night cable TV have web sites, but I wouldn't use them on a public building...

This is for a government building, and it just seems like the wrong product for this location/installation. I'm going to kick the issue back to the client for decision. thanks..
