Provides great adhesion to fiberglass, glass, most plastics, metal and wood
For use above and below the waterline
Paintable, Sand-able and more easily cleaned than polyeurethane sealers like Sikaflex
Advantages and Limitations
Advantages
Paintable and Sandable
No primer required
Fast skinning (10 min), fast curing (24-hours)
Outstanding adhesion to fiberglass, glass, plastics, metal and wood
Used above or below waterline
Easier to remove than polyurethane (i.e. 5200)
Permanent flexibility
50% joint movement
Limitations
Allow minimum of one week for full cure prior to total water immersion situations or painting
Do not use as a deck seam sealant
Not recommended for wooden decks
Not recommended for use in areas subject to regular gasoline contact
Elastomeric generally has good resistance to teak cleaners and oils, however it is advisable to test a small area for compatibility and resistance.
Where to Use?
Behind doors and storage unit frames
Thru hull fittings (above and below water line)
Deck hardware, windshields
Ports, hatches, rails and chain plates
Anywhere else a high quality marine grade adhesive is required

Does this work on Starboard?
Sudbury elastomeric sealant adheres to Starboard much better than silicone. It is the recommended adhesive for sealing/waterproofing behind starboard frames on tackle boxes and doors. With that said, it is not a substitute for mechanical fasteners and should not be used as the only means of structurally adhering starboard.
