## Questions & Answers

**Q: What is the coverage if using a trigger spray?**
A: Thanks for getting in touch.

Coverage for the FS-75 Fabric Sealer depends on the type of material being treated.

As a rough guide 1L should cover up to:

Lightweight Nylon 20m²
Lightweight Canvas 10m²
Medium Canvas 7.5m²
Heavy Canvas 3.5 – 5m²

**Q: What is the coverage if using a paint brush?**
A: It's difficult to say accurately as, to some degree, it will be affected by the material being waterproofed. I can only say that I was waterproofing my cratch cover which is a heavy  pvc lined canvas and I covered appropriately 4 sq. mtrs with 3/4 of the ltr bottle (750 mil). Hope this helps 😀

**Q: Dose this change the texture (feel), after treatment ?**
A: No barely saw any sign of the treatment once it dried

**Q: Want to waterproof a cotton fabric to use outdoors, will it work**
A: We’ve found it does work but to be honest, we’ve not had any heavy downpours!

Easy to apply and seems to work well. I applied 2 coats to a jacket, but the second wasn't really required and just ran off the surface.
