## Questions & Answers

**Q: What is the coverage area of the 500ml canister?**
A: Couldn't say in square metres, but gave good coverage of a large garden table umbrella inside and out, with some to spare.
Don't think it made a lot of difference though.

**Q: I make cotton fabric handbags, will this make them waterproof?**
A: Our FS-75 Fabric Sealer is compatible with most fabrics and is usually performs well on cotton. We always recommend testing for suitability on a small area before application to ensure good results.

**Q: Can it be used on nylon tent fabric, particularly groundsheets**
A: Yes

**Q: Would this be OK for canvas car roof please**
A: It is very good but I couldn’t say if it would work on a car roof , I have used a wax candle previously as this gets into the grooves
