RE: [bolger] Re: paint on epoxy?

I recommend washing down with white vinegar to remove the amine blush,
sanding it smooth with 100 grit (if it is a wood boat it should be naturally
fair) then prime with System 3 epoxy primer thinned with denatured
alcohol. As soon as the primer flattens (but before it is cured) I spray on
the first top coat of 100% latex enamel. I have a 15 year old boat that gets
a lot of use and it still looks good. Tim P Anderson

Dan,

Just about any paint will do the job if you prep the surface
right.
I once owned an Elver that I painted with an oil based exterior
house paint.The boat lived in the water(fresh) 6 months per year and
outside on land(cold) for the other 6 months.8 years later it still
did not need painting and never flaked or pealed either.

The surface(epoxy and 'glass) was given a thorough wash down with
this:http://www.dap

It really did the trick for me!

Good Luck!

Peter

And you just explained why it is worth the exspence to use quality
products it is less work in the long run and the boat lasts longer.

I have built several small ply/epoxy/glass boats to Bolger and Michalak
designs. The system I've had the best luck with, for the cost, is Kilz
II primer underneath regular latex house paint. Three coats of primer,
then three coats of paint. It will wear off when rubbing on gravel or
sand, but it's so simple and cheap to touch up every spring that I
can't justify the expensive epoxy or urethane paints.

The other one I tried that seems to last longer is Sherwin-Williams
Tile Clad II epoxy paint, then an oil-base compatible primer (Kilz
would work here, I believe, but I didn't use that brand), then oil-
based house paint. It's expensive and takes a long time to fully cure
(perhaps a month or two in my garage), but once cured has been a
reliably smooth, tough finish on my Light Schooner.

All of my boats live on trailers or dollies, or upside down outdoors.
The one I use the most, a Michalak Robote design, spent the Colorado
winter outside and hasn't seemed any worse for the wear - the gravel
shorelines here are much tougher on it than the weather.

If you don't ming spending $25/quart, I have had good results with
Interlux Brightsides (1-part urethane) over various brands of epoxy
(Systerm 3, MAS, RAKA).

For a boat that is going to be in the water only a short time (few days
max and most the time on the hard a two part topside paint over a good
primer will last a long time and look real good. Not cheap but will
wear and shine.

I have had no problems with Petit Easypoxy above or below the
waterline. Just sand the epoxy ( 100 grit) and paint,never used primer.
The paint you use is not as important as the primer. Make sure you get a good quality primer made for slick surfaces.

After a good primer, you can use latex house paint ABOVE the waterline and save money over the expensive marine types. Below the waterline, you need a paint that will stand up to water, so the marine epoxy-based paints are probably best.

The boat (a Nymph) will be taken out of the water and washed after use
so there's no need for anti-fouling paint.

I apologize for asking a question I am sure has come up before. Any
advice/experience regarding the best paint for an epoxy/fibreglass
hull? My only previous experience was with a Cosine Wherry that I
painted with an alkyd enamel and it flaked a bit (after sanding and
washing so it probably wasn't a blush problem).

The boat (a Nymph) will be taken out of the water and washed after use
so there's no need for anti-fouling paint.
