However, I wear gloves every application as it is sticky. To complete the curing time, you have to give it 24 hours. I like how it can stick to both porous or non-porous surfaces and dry or wet ones. I also use it to fix the rod and gutter.

What is Marine Sealant and How Does It Work


A marine sealant for aluminum boats is for use when leaks are on the vessel’s body. A small leak that you fail to repair may bring more damages. Hence, we need a sealant formulated to use on aluminum boats. Also, if you are a first-time user, fret not as the application is a breeze as long as you follow the manufacturer’s instructions.

Seams and rivets are the common areas with leaks. What the marine sealant does is strengthening the areas that require repair. Its penetrating ability also works on molding, decking, and stringers.

Marine sealant can do many things. For instance, it’s resistant to abrasion and impact. It’s a great feature as it prevents corrosion and blistering of fiberglass if you have it on your boat. Its resistance extends to chemicals, water, and potentially damaging environmental elements.

It does repairs excellently, and it can withstand the wear and tear along the way. Curing varies per brand, and after this process, you can paint the surface. Prepare the essential things before you start applying them on your boat.

Curing needs a little time, so you can return to the lake or river with your aluminum boat without waiting for too long.

Types of Sealers of Aluminum Boats


It is a substance that can establish more adhesion rather than just sealing. It will be practical to have it as it assures you of long-lasting hold. The strength of polyurethane is beneficial for making bonds on hull fittings and deck or hull joints.

This product works well on the aluminum surface but not on a plastic material that is fragile to oil and acid.


Synthetic rubber sealer is deemed as the most versatile material. A two-part application is usually part of this sealer. You have to understand that these parts are recognized as caulking items. It is not complex to use, and it gradually cures for a sturdy hold.

The two parts of polysulfide stick to different types of surfaces. It implies that you can have it in aluminum, other kinds of metal, wood, and glass. However, this sealer is not suitable for frames, plastic deck fittings, acrylic and polycarbonate windshields.


The application is super easy as silicone is elastic. It is also known as resilient to chemicals, and it’s an efficient material when separating things that are not metal. When it comes to adhesion, it is not as robust as the other materials.

You may need to get rid of tough debris, but nothing will stick with it like fresh silicone and paint.

Benefits and Drawbacks of Using Sealant for Aluminum Boats


An aluminum boat allows you to enjoy the water. The quality of the aluminum would be noticeable in just a glance, as well as the issues. This point of view encourages every boat owner to apply the sealant. With cracks and holes, the sealant would fix those issues and provide long term protection.

Hence, you’ll be able to avoid spending more money on necessary repairs. Some sealants would allow you to do the fixing while you’re on board, even with water around you. You can do it right away once you see the issues.

You will only come across drawbacks if you don’t follow the recommended steps of the manufacturer. Some cases are with inadequate drying time, or the mixture is not right. So you’ll end up with an unstable hold, and it suddenly peels off.

Buyer’s Guide

There are many reasons behind the need to get the ultimately effective aluminum boat sealer. You should get it to practice the real deal of the maintenance. It’s also what you need to do for the longevity of the boat. You can’t just choose the right sealant in a snap of a finger.

Here are some factors that you have to ponder onto:

Performance and Lasting Protection

An ideal aluminum boat sealer can provide maximum protection that can last for a long time. The product can make a solid bond and a reliable sealing capability, thus guarantees the optimal performance of the boat.

Some sealers are formulated for many applications. You must choose that one that can adhere to an aluminum surface pretty well.


The finish that a sealer can form should be resistant to chemicals, water, and environmental factors. It will be durable if it can surpass damaging elements in the surrounding, especially with weather changes. Chemicals shouldn’t be able to damage it too. Being waterproof is a good indication of its strength.

With its bonding ability and resistance, sealing and shielding will be an absolute provision.

Easy Application

It would help a lot if the application can be easily done. It also contributes to the effectiveness of the sealer.


It will be easy for you to decide when you consider the price as money matters. Not all expensive ones are effective. You’re lucky enough if you see a product that gives you what you need without spending too much. Don’t settle for cheap ones if you can’t attain what your boat needs.

Care and Maintenance

Here are some steps that can guide you for the necessary care and maintenance of aluminum boat sealer:

  • Stand by the instructions of the application and some safety measures given by the manufacturer. Always check the label for this before applying.
  • The coat of the previous sealer should be removed before getting started. The surface should be clean, and you can use acetone to eliminate tiny bits. You have to let the sealer dry before applying different kinds of coatings like paint and varnish.
  • Apply the proper amount of sealer. Don’t be stingy when you apply it on hulls and decks and fastening hardware.
  • Curing period varies from product to product. Some sealers would only need a few hours, and the shortest can be half an hour. But some may take a few days to get cured completely. You can count on its robustness when it takes a long time to dry and cure.

Moisture or dew that fills the air can hasten the curing period of sealer made of polyurethane and polysulfide.

  • When you are using a mechanical fastener to seal, don’t miss tightening the nuts because it will ensure a watertight bond.
  • Seal any leak or crack on your aluminum boat in a well-ventilated place. Prepare all the needed items.
  • Manufacturer guidelines are still important when it comes to removing the sealant.
  • You can use acetone, kerosene, and mineral spirits when removing spillage, excess, and misapplication. Such an occurrence can’t be avoided. You may also refer to the manufacturer’s instructions when making corrections or removing spillage.
