Ivermectin you can buy for use as a bug wormer for animals. It is easy to buy.

All you need is a small amount put into the paint. Notice only 0.1 % per liter.
You can buy it in paste form at 1.5% etc...., So for a few dollars you get an safe effective bottom paint.

here is a paste of 1.87%, also can get it in liquid form.

Just calculate the dose to 1 gram per liter.
Now what paint can be used versus buiying a cheap bottom paint and adding Ivermectin?

Ivermectin large amount pour bottle.

I think to get sufficient amount of Ivermectin into the paint using these sources as a DIY idea, you would have to use a larger bottle and mix it into a latex type of paint.
Perhaps the 1000 ml size which is $50 would give you a 5 gram total amount of Ivermectin which is enough for a little over a gallon of bottom paint.

If you can get this in a higher concentration would be more practical.

 

Great article, sounds like a great idea.

Out of interest, I just finished reading that Latex hasnt been used in paint for 30 years.

The right sort of paint will be important.

 

Is this effective against other kinds of growth, or just barnacles ? Maybe by latex he means Acrylic Latex, or possibly chlorinated rubber even. If the paste is using water, maybe only mixes with a water-thinned paint.
