Here are some instructions and
photos showing the process of applying our urethane teflon antifouling
paint to a canoe. The same process applies to boats of all kinds. And you

- less fuel used
- faster boat
- less maintenance in the long run and
better resale value
- ability to use pressure washing instead
of grinding or scraping to remove bottom contaminants
Note that growth on your boat bottom can
increase its drag by as much as 10%. With our non-stick coatings, that
growth can usually be released from a properly coated boat bottom when speeds
of 10 to 15 knots are reached. If the flow of water over your hull is
insufficient to wash off your growths you may need to brush or pressure
wash off the growths periodically. Typically you will not need to grind
off any growths. Once fouling has established a hold on a boat hull it
will rapidly spread or "colonize" the surface. Prevention is therefore
better than the cure of having to remove the fouling by scraping.

Reasons to keep your bottom free from fouling
Heavy fouling growth reduces responsiveness of the craft. The
added weight of the fouling can make the boat sit lower in the water than
intended. This can have obvious implications in heavy weather conditions.
Prolonged growth of certain types of fouling can damage the
substrate of the hull. For example, the natural glues which organisms use
to attach to the hull can damage wood and fiberglass. Fouling can also clog
water intakes and cause damage to the engines.
Speed and Efficiency
Fouling causes drag. As drag is increased, fuel
consumption increases and speed is reduced even to the point where a
planing hull may not be able to get on plane. For racing boats, this can
be the difference between winning and losing a race.
Smooth Sailing Antifouling coating is not meant to be a cosmetic or
decorative coating. Smooth Sailing coatings rely first on the large
molecule which produces a drag coefficient smoother than ice. Smooth
Sailing Antifouling also uses copper. Copper has been protecting boat
bottoms from growth since the 1700s when Britain's Fast Ships like the
Cutty Sark raced from the orient to England with cargoes of fresh Tea. All
antifouling paints change when they are
immersed. The true color will establish itself after the boat has been
launched. Along the waterline you will often note that the antifouling
coating looks dirty or faded and can often turn color from copper to a
dark gray and ultimately to a green tone. This is due to the
reaction of the paint with oxygen forming green copper oxide. Because
color change will occur over time, you should try to keep
the Smooth Sailing Antifouling coating as close to the true waterline as possible.
How often should a boat bottom be coated?
Smooth Sailing coatings will retain their antifouling properties as long as
the coating is on the hull.
Sanding between coats will add to the longevity of the bottom jobs. By
sanding the bottom in the spring you will get more coats to adhere and
forestall the day when too many coats means that you must remove all the
antifouling coatings from the surface and start over. Smooth Sailing
coatings must always be sanded even if they have just been power washed.
Because Smooth Sailing Standard and Smooth Sailing Antifouling bottom coatings wear
away with use, there is no buildup of coatings that will eventually have
to be removed from the surface. The minimal buildup reduces the
maintenance and preparation needed when it is time to apply more
antifouling. In contrast, Smooth Sailing Urethane lasts up to 12 years and is so hard
that it does not wear away. Because of its long expected life, coating
buildup is usually not an issue since five or six coatings can be applied
before any thickness build up is a concern.
A disadvantage to hard antifouling paint is that frequent applications
result in the buildup of residual paint film that occurs when the surface
is not properly sanded prior to application of new coats of antifouling
When hard paints are hauled and stored for the winter season, the paint
film, as well as the biocide, oxidize, making it more difficult to
release biocide out of the film. For this reason, they must be sanded
and re-coated with fresh antifouling before re-launching.
Smooth Sailing coatings use PTFE, the same chemical used in
Most people associate Teflon® with nonstick household products or with the
space program, but the properties that make it perfect for those
applications also make it an ideal ingredient in antifouling coatings.
PTFE creates the lowest coefficient of drag in any coating available. The
lower the friction, the less energy is required to move the boat through
the water. For powerboats this means greater RPM's, increased speed, and
fuel savings. For sailboats, greater speeds are achieved with less wind.
Because PTFE melts at 400 degrees or more it will not flow into gel coat
pores when wet sanded, so new coats can be applied at any time.
The level of copper is not the only determining factor of how well an
antifouling paint will perform.
The resin-binder system, the material that holds the paint together, has
its own antifouling agents and is
equally important. The amount of copper affects the life of an antifouling
coating but the sophistication of the resin-binder system to hold and
release copper is far more important to the effectiveness of the
antifouling effect. Smooth Sailing Antifouling will release biocide
at a nearly constant rate throughout its life. For this reason, the highly
efficient Smooth Sailing Antifouling is less dependent on large
amounts of copper to deliver the best possible performance.
Fluorourethane was originated by the U.S. Naval Research
(NRL) in the early 1970s. It was a combination of a fluorocarbon (Teflon)
with a urethane molecule. The material was unique in that it provided a
surface with approximately the same coefficient of friction as the Teflon, was
hydrophobic, UV resistant, and at the same time provided an abrasion resistance four times
that of Teflon.
The fluorourethane was originally tested on several ship hulls for the
U.S. Navy. One boat tested was a harbor tugboat in Chesapeake Bay. The coating lasted
11-1/2 years compared to a conventional hull coating which lasted only 18-24 months. Of
major interest was the fact that no rust or corrosion occurred under the coating.
And biofouling, such as barnacles, could be removed with a high-pressure water jet
instead of chipping or shot blasting.
