None of these are completely on the mark. The problem appears to happen in warm, humid environments with dew points maybe over 50 degrees or so. Amine Blush - many brands of epoxy, especially marine epoxies use a curing agent that will 'blush' during curing in cool, damp situations.
The result is a visible or not visible waxy film on the surface of the epoxy that affects the adhesion of anything applied over it. See our page www. The problem with the enamel paints not drying in not related to amine blush. Epoxy Not Cured Enough - most epoxies feel hard or dry in a few hours but continue to cure and harden for about a week. Generally it is best to paint or topcoat epoxy within a few days of the epoxy application, before the week full cure period has passed.
This way the solvents in the topcoat will combine with the not fully cured epoxy and product some chemical bonding as well as the normal mechanical bonding. Again, the problem with enamel paints are not related to epoxy cure times. Japan Drier and Cobalt Drier - are additives often added to enamel paints to speed up their dry time.
You can find Japan Drier at paint stores and Cobalt Drier at art stores. The Cobalt Drier works faster and better than the Japan Drier, but neither do more than speed up a little bit the extremely slow drying of enamels over most epoxies.
Our Basic No Blush marine epoxy is very popular with boat owners and folks needed to create or reseal pebble decks around their pools and yards. But like nearly almost all epoxies, our Basic No Blush epoxy contains Nonyl Phenol, a common chemical used in most epoxy curing agent mixtures.
Like us, our competitors use Nonyl in their formulations. See our Nonyl page. Under some conditions, the presence of Nonyl Phenol can slow or almost stop the drying of traditional alkyd enamel paints - a near crisis when building or restoring a boat and using popular enamel top coat paints. With the exception of this enamel issue, epoxies are generally considered a Universal Primer under all other top coat products especially 2 part polys.
The best fixes for the "enamel crisis" are:. These products are amazing and do not need to be top coated, leaving an egg shell light gray or aluminum UV resistant surface.

Using latex house paint on boats is a subject that is sure to raise lots of debate. The original supporter of latex on boats was Dave Carnell. Dave was a chemist and coatings expert and an icon in the boating and marine world. His text on latex is listed below. I believe it was first posted in Sadly, Dave passed away in It is posted here so that you can get the comments and thoughts of a number of boat folks on this topic.
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 thatsticks 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. 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 weather resistance of these polymers parallels that of the acrylic molding powders Anti Slip Paint For Boats 01 that make red automobile taillight and stoplight lenses that last forever without fading. All of the products are available as custom colors mixed to your desire.
A posting on the rec. 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. 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.
When I rebuilt my Simmons Sea-Skiff 20 I used a heat gun and a wide chisel to remove about a dozen layers of old oil paint. 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. I believe I will try it. 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. Jim Michalak, boat designer and builder, uses latex paint on his boats.
Boat builders 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. I received this a couple of days ago from a guy in Pensacola, FL. Just read your great article about using latex paint on boats. I had a 40' sport fisherman and I painted it with white exterior gloss latex. Just cleaned up the hull real good and sanded any rough spots, then put the latex in a gun, cut it with a little water to thin somewhat, and shot the boat and cockpit.
That stuff is tough, and holds up very well. The nice thing is you can simply touch up any gator marks that occur. I ran it about 5 yrs on a basic coat, then finally did an overspray.
Figured it would go another 5 yrs or so. Everybody thought I was nuts. I simply did what you did: pointed out how well it holds up on houses, fences, etc. Another nice thing is that, in many areas, it will touch up fine with brushes. T his current page is all about:. Painting epoxy coated surfaces - options and warnings.
As is well known on this forum and around Cape Cod, I too believe in latex. Learned the trick back in the '60's from Spaulding Dunbar. I was spot painting a repair just above the waterline at the bow.
