Steps to flash a pipe using CertainTeed SmartFlash ONE

1. First, get your field membrane in place, cutting a hole to accommodate the pipe.
2. When you're ready to flash in, start by roughing up the pipe.
3. Then, prepare the polyester fabric reinforcement. Wrap the fabric around the pipe, measuring with a 2” overlap.
4. Once you have that cut, cut fingers into the bottom half. This will allow the fabric to radiate around the pipe.
5. Next, we need our target patch, which will sit on top of the fingers. You'll take 6” on each side, overlapped by 2” in the middle. Simply cut out fabric to accommodate the pipe.
6. You can tape off the edges and pipe approximately 1” beyond the reinforcement. This allows for a clean finish. Now we're ready for resin.
7. SmartFlash ONE is thick and can be applied easily with a brush or roller without dripping. First, apply the resin around the pipe and onto the base at approximately 30 wet mils thick.
8. Then lightly press in your finger flashings.
9. Now fully cover the fabric with resin, making sure to put resin in the 2” overlap. You should not see any fabric.
10. Next, press in your target patch. Again, fully coating the surface and overlapping area with resin.
11. For full warranty coverage, up to 20 years, give this between 2-4 hours to dry and then come back with a final coat - approximately 30 wet mils thick.
12. Not required for warranty, but if desired for aesthetics, broadcast CertainTeed color-matched granules into the wet resin.
