Was just pondering this as I gear up to paint my boat inside and out. With the rise in insect carried illness (zika and such) having a permanent insecticide coating on the boat might be a real help. I have used the stuff in housepaints and am always impressed with how well it works, but don't know how well it would play with an LPU.

Advanced Insecticide paint additive can be added to latex or oil based coatings such as stains, varnishes and sealers for use to kill crawling and flying insects when exposed to treated surfaces.

You're going to be exposing yourself and your crew to the same chemicals which are poisoning the insects.

If it works, do you want to LIVE in an insecticide fog on your boat? ("paint my boat inside and out...")Does not sound healthy. LPU paints may also behave differently than houseplant. You could check with the manufacturer to find out more.

I’ll deal with the bugs using screens..... Big repelant is chemicals that will eventually kill you too. jump

I think there is a misunderstanding of just what this insecticide is.

The insecticide most used is deltamethrin, a synthesized version of an ester produced by chrysanthemums. It is used in treated mosquito nets, and even a laundry treatment designed to infuse bedding and children's pajamas.

The chemical is oderless and does not out-gas from the treated surface. There is no "fog". It works much like copper-coat does below the waterline. There is nothing in the additive half as dangerous as the stuff in Interlux Perfection (not singling them out, just the last paint I read the SDS for lately).

It is a product approved for application to residential walls. Nurseries and hospital rooms. It's a common paint treatment in homes where bug-born illness is a thing.

And I figured, with the advance of these illness vectors lately in Florida and the Caribbean especially, some cruiser might have thought of going this route.

The additive specifies an oil or water-latex paint, but LPU is not a common residential wall paint base (I don't think anyway)so maybe it's just not something that's come up.

No way, an LPU surface is impervious.

If you have an old can of half used LPU just try the mix.
Unless you have people licking the painted surfaces, I don't think you have much of an exposure pathway.
Zika, chickenguya (obviously made up spelling), malaria, and other bug borne diseases will probably have far worse consequences if you are infected than putting in some pyrethrin or other contact insecticides in paint.
I'd be a little careful in galley surfaces.

Pioson oak is odorless too and organic. Rapseed oil is used for cooking, but it IS canola oil used as a pesticide. It’s organic.

Consult with the manufacturer of the paint. You wouldn't want to mess up its chemistry for how it cures.

For mosquito prophylaxis, you need screens, and if you're going to be out there with them, you need insect repellent. Although, if your chrysanthemum based insecticide is used for children's sleepwear and bedding, you could probably use it to impregnate your clothing, and it would be fun to watch bugs settle on you and die.

We had a cockpit net, contrived from a bed net soaked in permethrins, that worked that way, and we felt safe to be out of doors behind our net in a high malaria area (the Solomon Is.) I also had a long sleeved blouse and a long skirt, similarly treated, that I wore if we had to go ashore. However, I did use DEET on my exposed skin areas. Never bitten. Lucky, but also, we were very careful. Mosquito prophylaxis is very important to me, and also against sandflies.

Good old chemicals...... to each his own. I’ll take the risk of mosquitoes rather than the guaranteed toxicity of chemicals.

All good!
Good luck!

I wonder if keeping a few plants (chrysanthemum) on deck and in the salon / galley would help ? Anyone tried this ?

I hope the joys of malaria or other insect borne diseases don't bless you with a visit.
PS - your entire boat is filled with modern industrial chemicals.
As for chemical toxicity, you do paint your bottom with anti-fouling paint, don't you?
