The Perfect Caulk To Do The Job Right!

One of our boat supplies, Life-Calk®, is a long lasting, permanently flexible marine polysulfide caulk which can be sanded, painted* and can be used above and below the waterline. Life-Calk® is a moisture curing system and under the ideal conditions will be tack-free in 1-3 days, and fully cured in 7-10 days. This product provides excellent resistance to teak oils, gasoline and diesel fuel. Life-Calk® is versatile and will bond to fiberglass, wood, metal, glass and itself. When cured, it will form a flexible rubber seal with excellent waterproofing and adhesion qualities. For emergency boat repair situations, Life-Calk® can be applied underwater for repairs, and can also be applied to damp surfaces. It’s perfect for use on teak decks, hull hardware, seal thru-hull fittings and underwater seams. Life-Calk® comes in Mahogany, Teak Brown, White, Black and Grey.** Our formula is the only polysulfide with an excellent performance record since 1959.

How To Prep Your Area:

The first thing you need to do is remove the old caulking. Cut along the caulk seam as close to the surface as you can on both sides. Next, you need to lift and pull the caulking out. After the majority of the old caulk has been removed, be sure to go back and scrape out any remaining caulking fragments. To be sure you get the best results when applying the new caulk, use a brush or vacuum to get any remaining fragments out, and use our Solvent & Cleaner to remove any residual oil, grease or dirt. Having a clean surface will help you get a perfectly adhering caulk seam that has the potential to last for many years.

Pro Tip:  Caulking Like a Pro

  • When using a caulking gun, apply caulk by “pushing” the caulking gun to avoid air pockets.
  • Temperature and humidity are the main factors that determine curing time.
  • Avoid freezing.
  • Do not store above 90°F
