Category Archives: Bottom Paint

What’s the difference between freshwater bottom paint and salt water bottom paint?

Typically there is less growth in fresh water than in salt water. For that reason, bottom paint used in fresh water usually have less active ingredients (copper, zinc, etc.) to prevent growth. Most bottom paint for salt water can be used in fresh water. However, there are some exception, such as, Interlux Micron 66. This paint is limited to salt water only. Using Micron 66 bottom paint in fresh water, or where there is a lot of fresh water run off, will result in failure of the coating.

Consider using a bottom paint that is good in both fresh water and salt water. All of Sea Hawk Paints bottom paints are good for either types of waters and are considered both fresh water bottom paint and salt water bottom paint. You never know where you might travel that will have significant fresh water run off!

Keep in mind that you probably don’t need the top performing paint like Sea Hawk Biocop TF bottom paint if you are in fresh water. You can go with a less expensive alternative like AF-33 or Silver Bullet. Anything more is probably over kill!

Applying Bottom Paint for Boats

Preparation is the key when painting on any surface. Applying bottom paint for boats is not the cleanest of jobs, but it really simple to do. Below you will find the exact steps to insure a good bottom paint job, whether you have a new boat, or a boat that has existing bottom paint on it.

Bottom Paint for Boats Preparation on Bare Fiberglass When painting a bare fiberglass / gel coat hull for the first time, it is extremely important that all contaminants such as grease, oil, wax, salt, or other foreign material are completed removed prior to sanding or application of a Sea Hawk System. Scrub the surface with a detergent soap and stiff bristle brush.

Clean

 

A. Clean and de-wax fiberglass hull withS-80 Wax N’ Grease Killer solvent based dewax. Saturate cheeseclothrag and wipe thoroughly to remove any cleaner and contaminants. Be sure to remove any residue before it dries and change rags frequently to insure contaminants are completely removed.

OR 

B. Apply S-90 De-Wax Etch & Cleaner with a maroon 3M Scotch-Brite® pad scrubbing thoroughly. Do not allow cleaner to dry on the surface and remove by flushing with water.Rinse entire surface with water and check for any beadingon the surface which will indicate that wax is still present. If necessary repeat step 2 again until the surface is contaminant-free. Choose your system below.

Sand and Clean

 

Apply Bottom Paint
Apply minimum of two coats of Sea Hawk bottom paint. Allow 3 to 6 hours between coats and a minimum overnight dry before launching. See the specific Technical Data Sheet for bottom paint being used. Some bottom paint for boats may require more than 2 coats.

 

Sand to a uniformly frosty, dull looking surface with 80-100 grit (no finer) sandpaper, rewash with S-80 Wax N’ Grease Killer , S-90 De-Wax Etch & Cleaner
Tip: Epoxy systems on the bottom of bare fiberglass is the best way to protect your boat against blisters. It also provides added adhesion of the bottom paint to the hull. Click Here for the steps that you need to take for proper application of a marine epoxy primer (barrier coat system) to the bottom of a boat.

Bottom Paint for Boats Preparation Over Existing Bottom Paint

Clean

 

Clean the existing boat bottom paint with a pressure washing. If you have excess build up of growth, you can remove this by scraping and or muratic acid. Try to get all growth residue off the existing old bottom paint so that you have good adhesion of the new bottom paint.

Scuff Sand
Scuff sand to a dull looking surface with 80-100 grit (no finer) sandpaper, then rinse with water and allow to dry. If your old bottom paint is really chalky, consider giving it a more agressive sanding to insure proper adhesion of the new bottom paint.

Apply Bottom Paint
Apply minimum of two coats of Sea Hawk bottom paint. Allow 3 to 6 hours between coats and a minimum overnight dry before launching. See the specific Technical Data Sheet for bottom paint being used. Some bottom paint may require more than 2 coats.

How to Apply Bottom Paint to an Aluminum Boat

Tuff Stuff Marine Epoxy Primer
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. Smart Solution is an excellent bottom paint for aluminum hulls.  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 Smart Solution.
