Mastic Tape Sealant

Marine-grade mastic tape sealant is a non-setting flexible marine sealant used on Freeman Cruisers to seal most external fittings from mooring bollards to fender cleats, & deck plugs to mast bases, and more.

All boat deck fittings (external fittings) should have a sealant between the fitting and the boat to prevent water from seeping into the superstructure and causing potentially serious structural problems and inconvenient aesthetic issues - mastic tape generally serves this purpose with exceptional results.

Boats can take a lot of abuse, bobbing around while moored up, little knocks and bumps, and perhaps great stresses while being lifted out of the water. Many sealants cannot cope with such movements but mastic tape, due to its material properties, can adjust to these movements. Its pliable nature means it can stretch, contract, and move with the boat, not against it - maintaining a complete seal.

As a testament to its exceptional properties, Mr Freeman used this mastic tape on the very first Freeman Cruiser, and the very last! Our marine-grade mastic tape is twice as thick as some 'cheaper' options now available (which seem to have stemmed from the caravan market!) and thus is better at producing the seal and will last longer once done. The cheaper versions are thinner which provides less protection, for less time too!

It is extremely important to maintain the seal on all deck fittings and reseal anywhere the membrane may have perished as this will help to prevent further serious problems - it is worth doing and keeping on top of constantly.
