Re: Varathane water or oil base?
Spar Varnish.....Whichever brand you prefer. None of the Varathanes
(brand name) seem to have the stated UV protection that Spar Varnish
has. Most seem to be Interior products, rather than Exterior. Plus,
Spar is about the same price. A couple-3 coats, and away you go...,
just a little sanding in between.

Thanks but I have read that article a while back just before i put
my first lap of house paint on my brick.
But I wanted to know if anyone has had good luck with varathane
water or oil based.
I'm looking for a clear ,fast drying, high build, no sag or
run ,scratch resistant, diamond hard, UV protected finish.

my first lap of house paint on my brick.
But I wanted to know if anyone has had good luck with varathane
water or oil based.
I'm looking for a clear ,fast drying, high build, no sag or
run ,scratch resistant, diamond hard, UV protected finish.

Latex Paint for Boats
WARNING: Warning this article contains material that may be
offensive if you think painting is more fun than boating.
When I bought my first yacht (27' auxiliary sloop) for $300 in 1951 I
quickly learned that if its for a boat, the same material costs
several times as much as if it is for your house. Oakum was $1/lb.
at the marine supply store; five pounds for a dollar at the plumbing
supply store. Marine paint cost several times as much as house paint
of similar composition. I worked for a major chemical company that
also made paint and knew that their paint that made the most money
and on which they spent the most on research was house paint. Houses
are out in the weather all year-no winter cover or inside storage.
Their owners expect to repaint them infrequently, such as every ten
years or so. They also expect a good paint job will require little
preparation before repainting. Back then the only house paints were
oil paints, so my yacht was painted with top quality oil-based house
paint.
All paints consist of binders or resins, pigments, solvents, and
additives. The binder forms the film that sticks to the boat and
holds the pigment there. The pigments color the paint, make it
opaque and have a good deal to do with UV resistance. Solvents keep
the binder dispersed or dissolved and the pigments dispersed in an
easy to apply state. They allow the paint to be applied in the
correct thickness and then evaporate from the paint film as it
dries. Mineral spirits, a petroleum distillate fraction, is the most
common solvent in oil-based paints. In latex paints, water is the
major fluid. It does not dissolve the latex particles, but disperses
them in suspension. Small amounts of special solvents are present to
control the coalescence of the latex particles into a tough,
tenacious film and to slow down the drying of the latex paint.
Through the years latex paints have developed to the point where 100%
acrylic latex paints are better than oil paints on all counts. They
are more durable and tougher. They resist chalking and fading,
retaining their color especially well when exposed to bright sun.
They are easier to apply, going on more smoothly and with less brush
drag. They have less tendency to grow mildew. They have almost no
odor and no fire hazard. Cleanup is with water. They can be
recoated in as little as one hour.
The 100% acrylic latex is the key to the outstanding latex primers
and paints now available. The weather resistance of these polymers
parallels that of the acrylic molding powders that make red
automobile taillight and stoplight lenses that last forever without
fading. I checked out all the top quality exterior primers, paints,
and porch and deck paints at both Lowe's and Home Depot-they are all
100% acrylic latex products (the Glidden latex exterior primer at
Home Depot used an organic nomenclature I hadn't worked with for 50
years, but my Handbook of Chemistry and Physics translated it to 100%
acrylic copolymer latex). All of the products are available as
custom colors mixed to your desire.
Your new boat went together pretty fast-instant boat or tack and tape
construction. What kind of a paint schedule can you use to get it in
the water next weekend. Let's say the inside will be all one color
and the outside all one color, not necessarily the same as the
inside. You can do the outside in one day, the inside the next, and
give it a couple of days before you launch it.
Here is the schedule. Sand it all over with 60 grit and clean up the
dust. Put on a coat of latex primer. That will raise some hairy
fuzz, so after drying a couple of hours give it a once over with 60
grit to defuzz it. Put on a coat of your exterior latex paint.
Gloss is the toughest and most durable, but also shows surface
imperfections best. Semigloss is almost as tough, durable, and easy
to clean as gloss while not showing surface imperfections. For me,
it is the usual pick. I have stayed away from flat paint.
You won't have to sand after the first coat of finish paint and you
can easily recoat in the afternoon. That finishes half of the boat.
The next morning turn it over and repeat the schedule for the other
half of the boat.
If you use two colors on the outside of the boat, you will add
another day to the painting. If you use different colors for the
bottom and the side on the inside and have a steady enough hand to
cut it in at the chine you can do it in one day.
While it is best to wait a week for the paint to dry hard, don't let
it keep you from getting in the water before next weekend.
A posting on the rec.boats.building newsgroup on the Internet asked
if latex paint was good below the waterline, as if it was going to
wash off. Look around your neighborhood. All those houses painted
with latex paint sit out in the weather all the time. My boats live
in the water with their latex paint jobs. Platt Monfort recommends
for waterproofing the Dacron® skins of his Geodesic Airolite
boats "...the simplest method being a good quality
exterior latex house paint."
How long is the latex paint job going to last? My sailing skiff that
lives in the water was three years old this spring. The inside,
especially the bottom, was scroungy from bilge water and having been
through two hurricanes, so I gave it a one coat repaint job this
spring. It looked great until Hurricane Bonnie messed it up this
year.
The 16-year old Uncle Gabe's Flattie Skiff (Sam Rabl) built of ¼" fir
plywood was painted when new and then about 9 years ago. It looks
pretty scroungy, but the interesting thing is that while the paint on
the wood has been scoured off by hurricane winds and general wear the
paint on the epoxy-fiberglass joints in the sides is perfectly intact
and looks great.
A fellow who was donating a boat to our local museum told me he had
the real secret to boat painting. He had painted a production
plywood boat with latex primer and latex paint. He was sanding the
paint off and found it was almost impossible to remove the last
traces of the latex primer because it had penetrated the wood to some
degree. Well, nothing soaks into wood like water and some of the
pigment particles are bound to be carried along with the water
vehicle of the latex paint.
When I rebuilt my 1964 Simmons Sea-Skiff 20 I used a heat gun and a
wide chisel to remove about a dozen layers of old oil paint. To
repaint I used latex primer and then two coats of Lowe's "Severe
Weather" 15-year guarantee semigloss latex exterior paint custom
colored to match the "Simmons blue" that was next to the wood. It
has been three years and three hurricanes ridden out on the mooring
since the boat was launched. Except where the boat has rubbed
fenders or the edge of the float and on the cockpit floorboards the
paint is in first class shape. I do need to repaint the
floorboards. In my survey I found that Lowe's has an exterior 100%
acrylic latex skid resistant paint (Skid-Not®) that can be custom
colored. I believe I will try it.
I am not alone in appreciating the outstanding performance of 100%
acrylic latex paints for boats. Thomas Firth Jones, boat designer,
boatbuilder, and author of Boats To Go wrote in Boatbuilder several
years ago that he preferred latex paint over oil paint for boats for
all of the reasons cited above. He did comment that he paints his
tiller with oil-based paint because the latex paint stains there.
I was talking with "Dynamite" Payson one May weekend a couple of
years ago and he told me he was going to repaint his skiff with latex
paint that weekend.
Jim Michalak, boat designer and builder, uses latex paint on his
boats.
Phil Bolger reported in Messing About in BOATS that his personal
outboard boat is painted with semigloss latex house paint.
Boatbuilders are traditionalists and it has been a hard sell to get
them to accept plywood, stitch-and-glue construction, epoxy
adhesives, and other similar innovations. Don't let tradition keep
you from benefitting from the ease of application and outstanding
performance of 100% acrylic latex paints.
