That night I checked the roof with an infrared camera and found moisture located under the rolled roofing where we sprayed but not much under the areas not sprayed. The next day we continued to apply our Polyurea and completed the project two days later. After one week the blisters had gone away. Two weeks later we applied an acrylic stain to the Polyurea to give the color of choice.

Penn Hotel - PenthouseMonroe, La

Kim and Melody Olson recently purchased a 10 story 80 year old building known as The Penn Hotel in downtown Monroe at the corner of South Grand and Grammont.

They have taken on the project to renovate the entire building and as of August 2008, they have done an incredible job. The building is not completed and it may take some months to experience the end result, however, the progress has been phenomenal.

Part of the project was making the penthouse larger and re-doing everything inside and outside. They contacted Pro Set, Inc. to waterproof their penthouse deck which consisted of rolled roofing.

This presented problems for us as we had to pump our Polyurea up 100’ to reach the roof. This was unknown since the highest we had ever pumped material was 70 ft. at a nuclear power plant.

We could have taken the machine up the elevator as we did when we waterproofed a 26 story roof in Ft. Lauderdale. But, we tried and were able to pump and spray by running the hose up the side of the 100’ wall. Our Graco 20-35 worked perfectly and we were able to complete the project without any problem spraying.

However, the obstacles were not over. We spayed only 750 sq. ft. the first day over the rolled roof substrate to make sure everything was working. It worked great, but the second day blisters appeared everywhere. The deck was approximately 12” thick and made up of different layers of concrete, roofing, concrete and rolled roofing. Apparently, traces of water had gotten trapped into the various layers and when we applied Polyurea at 170˚F it vaporized the small amount of water causing blisters.

Rather than cut out the blisters, we waited until the next day and found that they were disappearing. We did cut out one blister to examine it and found it to be adhered completely to the rolled roofing and in fact, the adhesion was so good that it pulled the rolled roofing apart since moisture got in between layers releasing the rolled roofing from itself.

That night I checked the roof with an infrared camera and found moisture located under the rolled roofing where we sprayed but not much under the areas not sprayed.

The next day we continued to apply our Polyurea and completed the project two days later. After one week the blisters had gone away.

Two weeks later we applied an acrylic stain to the Polyurea to give the color of choice.
