​BoatLIFE: Pioneers in Marine Sealant



Did you know that BoatLIFE introduced what can be called the first truly marine sealant to the market? We haven’t been touting the benefits of Life-Calk® for our own health. We’ve been doing it for the health of your boat. We say that with confidence because Life-Calk still has no direct competitors, making it the true marine sealant of choice.

But simply knowing about Life-Calk’s existence isn’t enough to ensure that your boat is adequately sealed. Here are some tips and tricks to ensuring that your own tube of Life-Calk gets its best use.

Why is Life-Calk Great for Sealing?

The equation is simple: you put Life-Calk on an area of your boat to seal it. So what separates it from the rest?

  • Life-Calk can be used both above and below the waterline—a truly marine sealant. It can even be applied underwater for emergency repairs, providing a highly waterproof seal that helps your boat’s overall seal against the water.
  • Life-Calk produces a seal that can be sanded and painted with compatible paints. Not only does this offer the seal you’re looking for, but makes it possible to keep it looking brand new without having to alter or damage the sealant.

Put together, these two benefits make Life-Calk a must-have marine sealant for both emergency application and for the best possible cosmetic seals on your boat. But there’s one more thing that boat owners will want to pay attention to: the difference between One-part, Two-part Type H and Two-part Type P sealants.

The Two Types of Life-Calk

Life-Calk can generally be broken down to Types H (Heavy) and Type P (Pourable). You can likely figure out one major difference simply by hearing their names. Type P’s pourable formula has an application time of only 30 minutes, which is better for quick seals and even cosmetic repairs to your boat.

With Type H, the application time is higher—some 60 minutes. This is generally better for seam-sealing, which can require a lot of sealant and a lot of application, especially when it’s applied to vertical surfaces.

How to Get the Most from our Leading Marine Sealant

Getting the right type of Life-Calk is important. But that’s not where your knowledge should end. We’ve put together a few tips for using Life-Calk to help you get the most out of your purchase:

  • Clean tools and applicators with Life-Calk Solvent & Cleaner . Since this is specifically designed to clean off Life-Calk, you won’t find a product more effective at keeping your tools clean.
  • Warm up tubes and cartridges of Life-Calk before using them in cold weather areas.
  • Push your caulking gun for best results—as opposed to pulling it.

And then there’s the matter of which Life-Calk product to buy. That only you can answer—but you can answer it over at our Boat Caulk & Sealants section, where you’ll see different products associated with Life-Calk, including cartridges and applicators. To get the very best for your boat, go with the only truly marine sealant.
