Unlike most roofing systems that require significant nailing or screwing, a fluid applied roofing system can be sprayed in place and offer a fully adhered membrane that offers some of the best waterproofing in the business. This particular roof had a unique situation in the fact that it had two different substrates, a large section of granulated BUR and a small TPO area. National Coatings was able to gain superior adhesion to both substrates without unusual preparation or caustic sacrificial primers. The unique performance capability of the A502 and A503 base coats provided direct adhesion to both substrates and also offered outstanding ponded water resistance to the rainy season that occurs during the Northern California winters.
This system offered a 10 year full system warranty and can be re-coated every 10 years, offering a truly sustainable waterproofing solution. Needless to say, both TriVascular and the building owners were extremely happy with the solution that kept the business up and running!
