The answer comes from Best Materials LLC, our online distributor..
We have seen some amazing results with the NovaTuff 100 product. We did a section of our existing white warehouse roof seven years ago. The standard elastomeric roof coatings turn off white after about 6 months. The NovaTuff product stays bright white, year after year. On our roof, we just applied the 100 as a finish topcoat.
We would like to finish up the roof someday….
I think one key thing to document is its ability to STAY white. It repells dirt for a LONG time.
