Tech Tips

SPF Gun Cleaners: Provides an overview of gun cleaning solvents and safe methods for basic spray gun cleaning.  SPFA's gun cleaner tech tip is a short and concise outline of how many spray foam contractors clean their spray foam gun and its associated parts plus key safety items to consider.

SPF - Exotherm vs. Thickness: When curing, SPF generates exothermic temperatures. When applied at excessive pass thickness, these temperatures can result in poor quality foam and, in some cases, can cause scorching or even self-ignition of the foam. This new Tech Tip provides some important information about the cause and prevention of high exothermic temperatures during application.

Maintaining Proper SPF Material Temperatures: If not properly stored within the manufacturer's suggested temperature ranges, foam chemicals can degrade and change viscosity, making them difficult if not impossible to apply properly. This new Tech Tip provides some general guidance on the proper storage and use of SPF chemicals to assure optimum shelf life and application during summer and winter months.

Picture Framing: Picture framing techniques for medium-density foam.  It details the procedure used to minimize cracks and voids when applying MD foam on framed cavity walls, roofs and floors.

Cold Weather Roof Coating Recommendations: When roof coatings are applied at temperatures below about 55oF (13oC), several challenges are encountered by the applicator. This new Tech Tip provides some important information about how to safely handle and apply typical roof coatings, as well as recommendations for storage, pumping, spraying and application techniques for coatings under cold weather conditions.
