This series of posts is designed to assist both new and trained professionals in the roof coatings industry. We take the information we have learned from contractors and chemists and either create a video or write a blog in order to assist contractors specifically with job site and application issues. You will find topics concerning best practices on job site storage to how to properly perform an adhesion test. For a more comprehensive learning experience, consider attending one of our bi-annual FAST (Fluid Applied System Techniques) Academy training sessions at our corporate headquarters in Mobile AL.

  • Heat Blisters in Dark-Tinted Elastomeric Coatings - Heat blisters have always been a concern when applying a dark-colored, high-build elastomeric roof coating during the hot summer months. Because elastomeric coatings dry from the top down, the excess heat causes the coating to skin over at an accelerated rate. The escaping moisture then becomes trapped and ultimately forms a blister. This past summer, an American WeatherStar Platinum Level contractors was ...
  • Tech Talk: Terminator Waterproofing Sealant - In today’s segment, Technical Services Director Eric Long is going to discuss the waterproofing power of Terminator 622 and 624XT. Terminator roof sealant is a 100% solids, moisture-curing sealant that adheres to nearly every substrate we have tested, including fluid-applied coating systems. Our testing even shows optimal adhesion to silicone. In this video, we demonstrate how ...
  • Technical Bulletin: Salt Spray Test for Acrylic 211 - 3,200 Hour Salt Spray Test for Acrylic 211 (ASTM B117) American WeatherStar is based on the gulf coast in Mobile, Alabama. Much of our roof coating projects under warranty are located in this region of the country throughout Alabama, Florida, Louisiana, and Texas. The coating restoration systems we develop must perform on roofs near salt ...
  • Tech Talk: How to Assemble, Operate, and Clean a Tank Spreader from Rooftop Equipment - When it comes to roof coatings, tank spreaders are easily one of the most important tools for roofing contractors. Because of it's simple design, tank spreaders require very little training, and can help contractors work more efficiently and increase productivity. In the two Tech Talk videos below, we go over the assembly of Rooftop Equipment’s 40” Super ...
  • Annual Maintenance on a Commercial Roof Coating System is Critical - As roofing professionals, if we promote and educate our customers about regular maintenance, it would be beneficial to everyone involved. The average building owner only purchases a commercial roof a few times in his/her career. They seldom understand that you cannot simply install a new roof or coating system without having to maintain the warranted system. Many commercial ...
  • Best Practices for Receiving a Shipment - When receiving a shipment, it is critical to ensure orders are received properly. We rely heavily on the LTL trucking industry to carry material from an American WeatherStar warehouse to your provided shipping address. All shipments require a Bill of Lading. The BOL is a legal document listing the contents of the order by number ...
  • Installing a Silicone Recoat - Over the past 10 years, silicone roof coating systems have taken over the coatings industry. Over time, many roofs utilizing a silicone system are now in need of repair and a silicone recoat. Because of this, we see a great opportunity for our AWS approved contractors to repair and recoat these older silicone systems. In ...
  • Tech Tips – Vertical Seams on Standing Seam Metal Roofs Do Leak! - Over many years of working with contractors that restore leaking metal roofs, we have learned that vertical seams on a metal roof can be the root cause of roof leaks. Since most traditional style panels are designed with a crimped seam of 3” or more above the panel, it seems counterintuitive that these seams can ...
  • Tech Tips – Tools for Properly Measuring Wet and Dry Film Thickness - Are your guys on the roof properly measuring coatings as they apply the system?  Do they have the proper tools to accurately measure wet coatings during application and dry film thickness once the coating has cured? [columns] [/columns] Once the job is complete, there are two types of measuring tools to determine dry film thickness ...
  • Overcoming Cold Weather Challenges For Roof Coatings - Working with roof coatings in winter months can be slightly challenging. Since the chemistry of each roof coating will react a little differently in cold weather, we will address the cold weather concerns for the materials that compose our core systems. Acrylics Acrylic coatings make up our Met-A-Gard and Met-A-Gard+ roof coating systems. Acrylic 211, High-Tensile ...
