PREPARATION & APPLICATION

Epoxy Primekote (formerly Epoxy Barrier-Kote) is a multi-purpose two-part epoxy primer that sands freely without loading the sandpaper.

Epoxy Primekote can be used with any topside paint but it is the recommended primer for use with two-part finishes such as Perfection and can also be overcoated with Toplac, Brightside, Interlux Yacht Enamel, Interdeck and Bilgekote. It is also used as part of a system to re-surface cracked and crazed gelcoat prior to the application of topside paint.

Use Epoxy Primekote over clear epoxies as a sanding surfacer and to eliminate the effects of amine blush. Epoxy Primekote is bright white, which makes it ideal for priming bilge and locker areas. When using Epoxy Primekote below the waterline, apply a minimum of 5-6 coats (10 mils minimum). Epoxy Primekote may be applied by brush, roller or spray.


BARE FIBERGLASS: Degrease with Fiberglass Solvent Wash 202 or Fiberglass Surface Prep YMA601. Abrade with 120-220 grade (grit) paper. Remove sanding residue.

CLEAR EPOXY: Allow three to seven days for clear epoxies to cure fully. Remove amine blush by using Fiberglass Surface Prep YMA601. Sanding does not remove contamination. Rinse with fresh water and allow to dry. Abrade with 80-120 grade (grit) paper. Remove sanding residue. Sand with 80 grade (grit) sandpaper and remove sanding residue with Brushing Reducer 2333N. Repair any defects with Interfill Watertite Epoxy Filler, then sand with 120-220 grade (grit) paper and remove sanding residue.

BARE METAL: Surface should be blasted to bright metal. If blasting is not possible, grind with 36 grade (grit) discs. Apply one coat of Interprotect 2000E that has been thinned 10-15% with Reducing Solvent 2316N. Follow overcoating times for InterProtect 2000E and then apply Epoxy Primekote.

BARE WOOD: Sand surface with 80-120 grade (grit) paper and wipe clean.

Cons: Epoxy Primekote contains numerous known neurotoxins (xylene) and carcinogens (benzene). Use only with a full face mask respirator with organic solvent cartridges (e.g. 3M 6000/7000 series cartridges), shave your shave and check to make sure you've got a good seal, wear a tyvek suit, good gloves and ensure as much ventilation as possible as the organic solvent cartridges can only filter out the solvents if they're below a certain concentration. Covering up as much skin as possible is important because these solvent go right through your skin and into your bloodstream. DO NOT FOLLOW THE PROCEDURES OF THE GUY IN THE Jamestown Distributors video who only wears gloves, a suit and safety goggles in a closed, poorly ventilated shop. These are seriously nasty chemicals that can do lasting harm. Interlux and Jamestown should emphasize this much more!!

Also, if you're laying down multiple coats of this stuff, its a real bear because it doesn't level well and require lots of arduous sanding.

Pros: Its tough and covers imperfections (deck crazing) well.

        Comments about Interlux Epoxy Primekote:

        This product has poor self leveling properties. If you use a marine roller you end up with stippling like a truck bed liner. If you tip of with a brush you get brush strokes. These two finishes require a lot of sanding to get down to a smooth finish. Once you have removed 90% of product you have a good smooth surface. Product was thinned properly no difference. Product too expensive, money & time, for me to do multiple coats. Best to try something else.

              Very poor self leveling properties (and yes I thinned as directed), that means if you are going to roll/tip your are going to spend many hours sanding back to get a smooth surface. For roll/tip apply 5-6 coats so there is enough thickness to sand out all the brush marks.

                Did two coats on FB, pilothouse roof and cabin top on a 36' Roamer Riviera. Il said to sand with 220 and that was FOREVER. Went with 150 to getter done. Took almost 2 quarts for good coverage.

                Comments about Interlux Epoxy Primekote:

                Please be sure you have leveled the surface. This is a final step and goes on thin so is not a filling epoxy coat. You should put on first coat with a roller. Do not press too hard with the roller. Use a foam brush to get the tight areas first then Start rolling with a gap where you have previously painted and then blend back into the previous area. A separate clean foam brush is used to drag along the top of the rolled area to tip off the area. I found a brush, all brushes just leave too many brush marks that do not float out and need to be sanded. One more thing Plan on at least two coats. The primer is a bit transparent and any filler clearly shows thru even after two coats. I am expecting extra coats of perfection may be needed to overcoat.

                Most LPU paints should bond well to any sanded Epoxy surface as long as the Amine blush is gone. the Amine free epoxies are better but I would treat them the same, just in case the humidity rose during curing. Better safe than sorry. I would rather find problems with the PrimeKote than later with the Perfection surface.

                I used two coats of primer then used a guide coat and saw waves in the boats surface after long boarding. Filled and sanded again and had to re apply two more coats of primer. I would suggest using a thicker barrier coat, or epoxy with the use of a guide coat before the final prime. Now the bottom and freeboard is right. The waves were about 3 inches crest to crest. they were about 20 mils deep. A little too much for the PrimKote product. Used the 3m filler because it is what I had and it sanded out well. The WaterTight stuff is the same if not better. It has a little longer working time. Again the filler material shows thru the primer.

                                I've used alot of different products and painted alot of stuff if my time. This was the first time I ever rolled anything, Ive always sprayed. It's thick like the old laquers, stir the base and activator seperatly then combine, then thin, It was about 80degrees when i was aplying it so i thinned it 25 percent with the brushing reducer as instructed on the can and achieved good results. I rolled it out with a foam roller and did not tip. It did dry with an orange peel finish but you have to sand it anyway. It sands easily and feathers out really nice. It takes about 3 coats to hide any filler you may have behind it. All in all its just like any other quality paint but the best part about it is the price. Its cheaper than others I've used in the past and is no better or any worse. You cant go wrong.

                                Comments about Interlux Epoxy Primekote:

                                I did much reading and spoke to a couple folks at marine stores before buying. I also found a couple YouTube videos on Interlux products before selecting Epoxy Primekote to go over old gel-coat. The research was a wise investment as the results so far are great. I have some experience with autmotove paint systems and expected more spot filling. I misted a shadow coat of dark sandable primer over my first coat of Epoxy. I'm block sanding with 220 and I'm finding that this primer - even thinned 25% - filled in so many small imperfections that I believe my second coat will be the last. It does sand harder than automotove primer, but it is an epoxy so that's to be expected. That same toughness will help you from sanding through edges. Use lots of water when sanding - it really helps. I intend to cover with 2-part urethane.
