Sealant tape for building and marine repairs, LLPT Butyl Seal Putty Tape, is designed to deliver watertight, flexible sealing for windows, RVs and roofs. Tradespeople and keen DIYers gain a quick, mess-free application and a paintable finish that blends into repairs. Will the 10m roll and non-drying butyl compound cope with regular maintenance chores?
⚡ At a Glance
- • Sealing Performance: High-viscosity, elastic butyl compound forms an immediate water-tight barrier against wind, water, dust, oil, grease, vapour and moisture
- • Best for: RV and boat owners, window and door repairs, mobile homes and general DIYers who need fast waterproof reinforcement
- • Not ideal for: Precision structural joins or applications that require mechanical fastening rather than a flexible seal
Synthetic composite butyl rubber remains tacky and elastic, giving instant adhesion and shock absorption. Easy moulding and high viscosity allow reliable sealing across uneven surfaces.
Watertight sealing - with high-viscosity synthetic butyl compound
High-viscosity synthetic composite rubber stays tacky rather than drying out, creating an immediate bond when pressed onto a clean substrate. Elastic properties absorb movement and maintain contact under vibration or minor shifts.
Immediate water-tight repairs for windows, RV seams and roof patches, preventing wind and moisture ingress without messy wet sealants.
Conforms to awkward shapes - with easy moulding and elasticity
Soft, malleable putty tape moulds around tight corners, unusual curves and jagged edges, maintaining continuous contact across glass, metal, wood, plastic and rubber. High elasticity ensures the tape follows movement without splitting.
Effective sealing on irregular surfaces means fewer gaps on retrofits and mobile-home joins, saving time on trimming and secondary sealing.
Neat, paintable finish - with a paint-accepting surface
Tape surface accepts paint after application, allowing a flush finish over repairs; ideal installation temperature is around 10°C, as lower temperatures make the tape stiffer and slower to mould.
Repairs can be disguised for a tidy appearance on boats, caravans and window frames while retaining a flexible, long-lasting seal.
✨ The 4 Key Reasons for LLPT Butyl Seal Putty Tape
- Instant adhesion - Creates a watertight seal within seconds of firm pressure
- Mouldable elasticity - Wraps tight corners and curves without losing contact or seal
- Paintable surface - Lets patches be covered for a neat, low-profile repair
- Generous 10m length - Reduces runouts during larger jobs, needing fewer joins

❓ Frequently Asked Questions
Q: Which surfaces is the tape suitable for?
A: Glass, fibreglass, wood, coated or uncoated metals, plastic and rubber are all listed as compatible surfaces.
Q: Is the tape suitable for outdoor use and roof patching?
A: Application notes include indoor and outdoor use and specific mention of EPDM roof and galvanised metal roofing patching.
Q: How should the tape be applied?
A: Clean the surface, release the tape and press firmly all around the area; install around 10°C where possible because lower temperatures make the tape stiffer and slower to mould.
🏆 Our Verdict
Ideal for RV owners, boat owners, tradespeople and DIYers who need fast, waterproof repairs on irregular surfaces. The non-drying synthetic butyl compound moulds easily, accepts paint and holds a watertight bond while remaining flexible. Large 10m rolls and durable, non-hardening composition deliver strong long-term value for recurring maintenance tasks.
