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. ## Frequently Bought Together - Liquid Rubber Waterproof Sealant – DIY Leak Repair Coating for Flat, Metal & Low Slope Roofs, Foundations, Gutters & More – Flexible Protective Membrane - Black - 1 Quart - Pro Grade, Paint Brushes, 5-Piece, Paint Brush Set: Flat & Angle Brushes for Latex and Oil Paints, Stains, Interior & Exterior Home Improvement - Tondiamo 4 Inch x 98 Foot Textile Fiberglass Waterproofing Roof Tape Anti Fracture Membrane Fabric Sheet Reinforcing Mesh Fabric Liquid Drywall Tape Waterproofing Membrane for Shower Walls and Tiles --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.us/products/432088356-waterproof-sealant-multi-surface-leak-repair-indoor-and-outdoor-coating](https://www.desertcart.us/products/432088356-waterproof-sealant-multi-surface-leak-repair-indoor-and-outdoor-coating) --- *Product available on Desertcart United States of America* *Store origin: US* *Last updated: 2026-05-15*
