Product Overview:

EPaint EP-21 White (EP-21-401) is an ablative foul release boat bottom paint boats in fresh water and low to moderate fouling salt water

EP-21 offers excellent protection without toxic pesticides or a high price tag; the secret is a combination patented ePaint photo-active technology and ablative finish; it erodes away like a bar of soap, self-cleaning the paint in the process.

Practical Sailor Magazine recommends EP-21 as a best "$ Budget Buy" and rated EP-21 "Excellent After 6 Months" (March 2010) and "Good After 12 Months" (October 2009) in Florida waters!

EP-21 applies just like traditional copper-based bottom paints and multiple coats may be applied same day. EP-21 is compatible with most epoxy primers and over most traditional antifouling paint systems.

EP-21 is safe for use on prepared aluminum, fiberglass, wood, outboards, outdrives and trim tabs.

As EP-21 is ablative, it is important to apply an extra coat or two for extended service life. However, EP-21 costs much less than similar performing copper-based paints.

EP-21 is copper-free and will not promote electrolysis on prepared metal parts, white color will not patina stain, and paint wears nice and smooth. 

Consider using a little EPaint EP-13 thinner to help reduce viscosity for improved application, better coverage, and cleanup.

EP-21 does not contain a biocide and it is not considered an antifouling coating. Some maintenance scrubbing may be required to keep boat bottom clean if boat sits but growth is readily removed with little effort as long as paint is on the hull.
