Outside of the hull, there may be no better place on your

area from another is the name of the game here—and if you don’t have it properly
sealed down, it could lead to all sorts of problems. The good news is that boat

the right tips and tools at your disposal. Here at BoatLIFE, we’ve got you
covered with both.

Measure Twice, Seal

have to do some research and matching. Taking your time might seem like it’s
only prolonging the process, but it could save you a few trips to the hardware
store down the line.

time to clean out the surface. That means stripping away the old materials and
using solvents and

may simply have to wait as the solvent does its job. While you wait, you can
prepare for the next steps in the boat hatch gasket replacement process.

careful here to really apply the gasket well. It’s a good idea to take your
time. After all, it’s your seal we’re
talking about here. You get to decide how snug the fit is. To truly
weather-proof your boat, the proper-fitting seal will be the difference between
professional and amateur work.

adhesives to ensure everything will stay in place. Browse through our boat sealants to match

try. Inspect it for leaks and make sure that nothing is getting through. After
