Interlux Pre-Kote Primer for One-Part Finishes

Interlux Pre-Kote primer is used above the waterline prior to painting topsides with Brightside polyurethane, Toplac, yacht enamels, or any one part topside finish on wood, fiberglass, and previously painted surfaces.

Pre-kote contains microspheres for superior build and hide. Microspheres also make it easier to sand.

This primer requires thinner INT-0333 (for brushing) or INT-0216 (for spraying).

Available in Gray or White.

I am very pleased with how it worked


I liked the simplicity of a one part undercoat. I used it on the boat interior, which already had two coats epoxy. I had a question about using it on epoxied wood the Interlux tech rep was very helpful. Then I painted two coats Wet Edge Cold Cure. I am vary happy with the end result

Use Anything But This!


I have years of experience in the marine industry. I started working in a boat yard 20 years ago and since then have worked on clients, friends, family, and my personal boats. I also have 15 years of commercial blue water experience sailing onboard ships in positions from Ordinary Seaman all the way to Unlimited Master. I have used many Interlux products along with many other manufactures products both in the recreational and commercial marine industries. Out of all the primers I have ever used this is the WORST primer. I tried thick, thin, roll and tip, etc. and no matter how the primer was applied or no matter how long it was allowed to dry I always ended up with horrible results. Ultimately the only way I was able to properly sand this product for top coating with Interlux Brightside was by wet sanding. I have three different Festool sanders along with the respective dust collector and Festool abrasives, none of them were able to sand this primer for anything longer than a few seconds before loading up. I was eventually able to get mediocre results by hand wet sanding with 220 grit wet/dry abrasive. I will NEVER use this product again. I will start trying different 1 part polys and their respective primer even though Brightside has been my go to topcoat for a easy and durable 1 part poly.

This is a great primer


I used Pre-Kote on my deck of a fiberglass boat. It goes on very easy and has excellent coverage. It was just the product I was hoping for.






Product applies and covers great

Works Well


Used it for years with great results.




Pre Kote


Good product. Price is right, easy to apply and dries quickly enough that runs don't occur. Also easy to sand to a smooth finish and it fills a lot of the small divots that occur in your previous epoxy layers




The basis for a great finish


Two or three coats of Pre Coat sanded well gives a great base for a fabulous Brightside finish. Thin the Brightside with a capful of 333 thinner to enhance flow in warmer weather.

Great product at a great price and fast shipping AAA +++

Great base coat


Sand well prior to application with 120. Then with 220-320 to smooth out and reduce scratches. Wipe surface with acetone and follow with a cloth dampened with 333 brushing fluid (if rolling/ brushing). Build coats, sanding between. I added some of my finish coat (Blu-glow White) to last coat to promote adhesion to the primer for the finish coats)
