## Questions & Answers

**Q: Can this be used on leaking asbestos garage roof**
A: Was able to seal fibre glass pond. I’m sure it would be suitable to seal asbestos garage roof

**Q: Can this be used on epdm roof?**
A: Yes you can but you need our EPDM Primer 1st

**Q: Can it be painted over with a cuprinol shed paint,when used on the side of rain leaking shed. Thanks**
A: Thank you for reaching out to us.

It is generally not recommended to paint over it for exterior applications as the paint will likely not expand and contract as well and this will likely lead to the paint cracking and peeling.
Also, as it is a bituminous product, It can bleed through the paint over time.

I would recommend that if you want a colored product use Liquid Rubber Color Waterproof Sealant instead.

Liquid Rubber USA/CAN has great technical support, application info and instructional video's.
Have a great day!

**Q: Can this be used over a fibre glass roof?**
A: Hi, yes you can use the Liquid Rubber Waterproof Sealant over a fiberglass.  Make sure to rough the surface up first and clean well.  Bridge joints, seams, vents.... with Liquid Rubber Seam Tape first.

Really good stuff for cheap roof repair. I’d probably only use it as a temporary solution however as it does seem to degrade after a few years

### ⭐⭐⭐⭐ Easy to apply
*by K***N on 29 August 2023*

Applied 4 coats to my osb timber shed roof within a 2 day period of no rain about a month ago.. We've had some heavy rain since and also some really hot days and so far so good.. have enough left for one more coat. My roof is 3m x 5m.. goes on brown then turns black quickly... Time will tell..
