The Foreman’s Guide to Proper Propane Melter Safety
Before operating a rubberized asphalt melter, it is the obligation of everyone involved in its operation to know, understand, and follow all recommended safety procedures, local ordinances, and codes. As with all safety programs, written directions and codification must be combined with individuals exercising common sense with a high awareness of safety issues. This is…

When it comes to maintaining the roof of your home or commercial business, cold-applied coatings can be fundamental for performance and lifespan. There are many reasons to apply a coating to your roof, though the most common is to maximize the service life by reflecting ultraviolet radiation away from the membrane. Coatings can be used with…

Restore & Repair So You Don’t Have to Replace Bituminous roofs and flashings oxidize and dry out as they age. Becoming increasingly brittle, they eventually split open from natural contraction and expansion cycles. These, along with other forces, cause roofs to become increasingly susceptible to moisture entry as they age. Once moisture enters the system,…

THE MOST IMPORTANT PRINCIPLE OF WATERPROOFING Each separate envelope trade contractor’s work, regardless of its being thought of as a waterproofing system or not (e.g., exterior mechanical apparatus), must become part of a totally watertight building envelope. Equally important, all individual envelope systems must be adequately transitioned into other components or provided with watertight terminations.…

There is a significant difference between standard oxidized asphalt ASTM D-312 Types I, II, III and IV and unoxidized asphalt materials. The ASTM D-312 products utilize a petroleum derived material called “flux” which is put into a still, heated while air is induced, which essentially ages the asphalt flux to a point that is within…
Read MoreThe Foreman’s Guide: 11 Popular Cold Process Options for Re-Roofing & Surface Restoration Applications
Cold Process Systems consist of multiple plies of reinforcement sheets that are set in a cold adhesive (solvent based or water based). These systems are often referred to as cold process BUR systems because the application procedures are similar to hot applied BUR systems. The most common reinforcement felts are manufactured from fiberglass or polyester, which…

“Will deicing products have any effect on Barrett’s RamTough 250 hot rubberized asphalt membrane?” Using ice melting compounds to clear snow and ice from plazas, drives, public entryways, and other pedestrian & vehicular traffic surfaces is virtually a universal practice today. Facility maintenance personnel learned long ago that to achieve safe surfaces in the shortest…
Read MoreThe Foreman’s Guide: Cold Weather Applications for Roofing, Waterproofing, and Restoration Systems
Application of a roofing, waterproofing or restoration system in cold weather can be achieved successfully, within certain limitations, if precautions are taken. It is important to understand what may be encountered during cold weather applications and what material and manpower limitations exist. Following these cold weather suggestions will help provide greater application efficiency and system…
