What is the Best Bottom Paint Money Can Buy?

Best Bottom Paint

Best Performing Bottom Paint

The best bottom paint that money can buy may NOT be the most expensive. You should buy the bottom paint that works best in your area. That will depend on the temperature of the water, tide changes, the nutrients in the water that feed unwanted growth, and many other factors.

The best bottom paint for you will be the bottom paint that stops the growth and does not break your wallet. If you buy the best performing bottom for the harshest fouling conditions and the warmest waters you would need Sea Hawk Paints Biocop TF  or another Top Performing Bottom Paint. This provides you the absolute maximum protection against hard and soft growth on the bottom of your boat. This solution is recommended for high growth areas, or if you are trying to goes as long as you possibly can between bottom jobs. If you are in cooler climates or lower fouling conditions you would NOT need to spend the extra money on Sea Hawk Biocop TF. A better choice that is less expensive and will work in these conditions is Sea Hawk AF-33 or the equivalent.

ALUMINUM BOATS: The best bottom paint for an aluminum boat or pontoons is a copper free bottom paint. You cannot put the paints mentioned above (Copper-Based) on aluminum because they contain copper and will react like a battery causing pitting (holes) on aluminum. Therefore, we recommend an Aluminum Safe Bottom Paint. A good choice for aluminum is  Sea Hawk Colorkote, it is copper free triple biocide paint  safe for aluminum. If the aluminum has never been painted the best practice is to prime with high build epoxy primer like Sea Hawk Tuff Stuff to insure good adhesion and protect against corrosion. If you are painting a pontoon boat for the first time – try our Pontoon Bottom Paint Kit.

Premium Outdrive bottom paint kitThe best bottom paint for the outdrives is to brush on Smart Solution. (pint size).  If your outdrive has never been painted before, you can use Barnacle Blocker Primer for priming the area application of bottom paint. A great value for this is the Premium Outdrive Bottom Paint Kit. If there is already a bottom paint on your running gear, just scuff sand and paint! Another option is to try an aerosol spray bottom paint. These are easy to apply.

For outdrives a foul release agent may be the choice for you, see here.

How to Apply Bottom Paint to an Aluminum Boat


Tuff Stuff Marine Epoxy Primer

If you do not have any coatings at all on the bottom of the boat, we suggest to sand the hull with 80 grit and then apply Tuff Stuff High Build Epoxy. It is a water tight barrier coat designed for use under the waterline and with aluminum hulls. Use 2 coats. You can apply the 2nd coat within a couple of hours of the first coat. (up to 6 days)

After you apply Tuff Stuff marine epoxy primer on hull, be sure to use an aluminum safe bottom paint. The bottom paint needs to be applied the same day as the Tuff Stuff marine epoxy primer. Bottom paints in general are designed to repel hard growth. Colorkote is an excellent triple biocide bottom paint for aluminum hulls when in salt water. We recommend Mission Bay for fresh water.  I have listed links below to the products described above. These can be brushed, sprayed, or rolled.  If you already have coating(s) on the hull, pressure wash, sand with 80 grit, and then apply your paint choice.
