## Description

LLPT Butyl Seal Putty Tape | for Leak Proof RV Repair Window Glass Boat Sealing EPDM Roof Patching (WST233) | White | 25mm x 10m x 3mm Thick : desertcart.co.uk: DIY & Tools

Review: Good Stuff - Used this to repair a inner door lining on my car which wasn’t stuck down properly allowing a little water leak, easy to apply and stuck the lining down very well so fingers crossed no more leak.
Review: Sticky, sticky..... - I usually buy a mastic based sealant to seal my Motorhome roof windows, after a recommendation from a friend I looked at the Butyl strips as an alternative, the other 'Named' brands were a 5 meter roll for roughly the same cost as this item but this one has 10 meters on the roll so better value straight away. Still a bit sceptical, I installed the tape on the roof and Ohh my word, it sticks, I mean, it really sticks, when you use this you only get one chance to get it right, so be precise and certain you have everything lined up correctly. The window has been fitted and it has sealed perfectly, there was heavy rain that evening and there were no leaks at all. Highly recommend this tape and I certainly won't be going back to the mastics.

## Features

- APPLICATION: Widely used for window and door waterproof reinforcement, airtight sealing, windshield, RV, retrofit, pipe, joint sealing, mobile home, glass, EPDM roof or galvanized metal roofing patching for indoor and outdoor.
- WORKING PATTERNS: Suitable to be use on glass, fiberglass, wood, coated or uncoated metals, plastic, rubber at tight corners, unusual curves, uneven and most jagged surfaces; reliably shut off wind, water, dust, oil, grease, vapor, moisture, corrosive chemical and other leakages; paintable feature is making your installation area a seamless, clean, dry and heavy duty water tight workspace.
- FEATURES: LLPT Butyl Putty Tape (3.5mm/0.14 inch thick) is made of synthetic composited rubber for non-drying, non-hardening and extremely working temperature that provides easy installation, easy forming, quick molding, shock-absorbing, mess free, air tight sealing, waterproof, high viscosity and elasticity.
- EASY TO USE: LLPT Sealant Putty Tape delivers easy molding and instant adhesion to the surface of object. Simply clean the surface first for better bonding and release the butyl tape to areas you want to seal with proper press all around the tape. The ideal installation temperature is around 10 Celsius degree, to low will make the tape stiffer which might need a little bit longer time for molding.

Search on desertcart for other LLPT tapes like PET Repair Tape, Woodworking Tape, Aluminum Foil Tape, Foam Tape, Black/Gray/Clear Acrylic Mounting Tape, Duct Tape, Silicone Tape, Caulking Tape, Gaffer Tape and so on.
