High-build primer
I'm finishing a glass composite boat and intend to use LPU paints. I've been using Interlux 401/414 , applied by roller and brush. I'm generally satisfied with it, but it doesn't build quickly. Is there other primer I should try?

The Interlux product data sheet for 404/414 recommends only two coats
for use above the waterline, with each coat having a Dry Film Thickness of only 2 mils. (The only bummer about 404/414 is that you need to sand between coats...). Could it be that you're after 'high build' to help solve fairing problems? The primer is simply meant to provide a tie coat between faired hull and the LPU; to quote I'lux: "Use Epoxy Barrier-Kote over clear epoxies as a sanding surfacer and to eliminate the effects of amine blush". So, high build is not required! If you're after high build to fill-in some valleys... a batch of microbaloons / cabosil and a putty knife might be better. BTW, I'lux has a new LPU system that looks very interesting: 'Perfection'. See the video at: http://www.yachtpaint.com. MW Los Angeles |

The are lots of epoxy companies that sell epoxy coatings with dft of 4 - 16 mils or so per coat rolled. Any would work as a LPU primer. \ paul oman progressive epoxy polymers -- |
