Johnson Rubbaweld mast boot tape is the perfect solution for waterproofing deck aperture for keel-stepped masts. It creates a flexible, long-lasting, good-looking professional joint that will not leak.
This Rubbaweld® professional grade self-amalgamating mast boot tape is 4" wide for sealing the mast at the partners, where it passes through the deck.
When properly applied, this tape bonds to itself to form a single integral structure. The tape is adhesive-free, so there is no stickiness to deal with when applying.
Can withstand high temperatures for uses such as emergency repair of engine water hoses.
