To Whom It May Concern:

We at Tropical Tile & Marble, Inc. have used the crack isolation membrane known as Proflex in several of our custom installations. Those installations range from interior to exterior such as garages, commercial offices, condominiums and interior custom home flooring. We are especially pleased with the Proflex PR-27 exterior grade primer in which we use now on all of our installations. This is due to the ease and quickness in which an installer can prime the substrate and immediately install the Proflex membrane. This is not so with most of the competing sheet membranes. The adhesion to the substrate is also superior. We have had situations where the other membrane primers, installed properly, allow the membrane to loosen, even with the use of a 75# steel roller; also, the wait time on a lot of the other primers slows the installation process.

We will be using the Proflex 90 Mega Sound Control shortly on two of our condominium jobs. This is in lieu of cork, so we don’t have to worry about the hollow sound cork can give a floor nor do we need to worry about moisture from the mud-set.

Another point that helps all installations is the cost has been .05 to .10 cents a foot cheaper than the other membranes. When we are doing 3000, 4000 and 5000 sq. ft. jobs, this equals a considerable savings and furthermore, they have an outstanding warranty! Proflex is a superior product that we foresee using for quite some time.

Dear Al,

Just a short note to thank you for recommending the Proflex Membrane Products to me. Since we first talked about an alternate to cork as an underlayment for tile in our condominium we have had three owners who have used it. As you know we are presently having our entire atrium re-tiled and happily they are using Proflex 70SSC as the underlayment.

I urge all owners remodeling here at the Savoy, as well as their tile contractors, to quote the Proflex products in lieu of the 1/4" cork. The sound reduction from floor to floor is greatly reduced and using the thinner product eliminates the need to cut down the steel entry doors. Those two factors alone make it worth the small price difference. All of the other pluses these products offer is pure gravy.

Feel free to share this letter with potential users who still may consider 1/4" cork a good product under any floor. It sure doesn't deter sound transfer from floor to floor.

Sincerely,

Phil Paradis, Director of Operations

Dear Joe,

Pursuant to my conversation with you last week, we have evaluated the Proflex samples that were shipped to our Middleton, MA facility.

Bostik's Best and BST was used to bond engineered wood flooring to Proflex CISM, Proflex 70 SSC, Proflex 90MSC and Proflex 100 USC. Adhesion was found to be excellent to the Proflex products. Based on the test results, Proflex CISM, Proflex 70 SSC, Proflex 90MSC and Proflex 100 USC would be suitable for use with Bostik's Best and BST.

Please refer to the enclosed Bostik's Best and BST Data Sheet for complete installation instructions and standard product warranty.

If you have any questions, please feel free to call me directly at 978-750-7234.

Sincerely,
BOSTIK FINDLEY
