Interlux Perfection Plus Two Part Varnish

Interlux Perfection Plus varnish is a clear, two-part polyurethane high-gloss finish for wood and epoxy. This high-clarity, high-gloss marine varnish provides superior UV protection and prolonged resistance to chemicals and abrasion.

The Plus formula is Interlux's most durable, a finish that lasts up to four times longer than conventional one-part varnish products. Designed for above the waterline use, the chemical cure of Perfection Plus provides superior resistance to fuels, oil and mild acids and alkali spills and is fully compatible with oily woods such as teak.

BARE WOOD: Sand with 80 grade (grit) paper. Wipe with Brush Thinner 2333N. Apply a sealer coat of Perfection Varnish reduced 10% with Brush Thinner 2333N.

PREVIOUSLY PAINTED SURFACES: With Perfection Varnish: In Good Condition Sand surface with 120-150 grade (grit) paper and remove all dust. In Poor Condition If varnish is badly checked or peeling, remove finish to bare wood with Interstrip Semi-Paste 299E.

CLEAR EPOXY: Allow epoxy to cure for 5-7 days. Begin by scrubbing well using soap and water and a stiff brush. Wash down with fresh water. Wet sand with 180-220 grade (grit) paper. Wipe with Fiberglass Solvent Wash 202.

Method Apply at least 5-7 coats on bare wood and a minimum of 3 coats on surfaces previously coated with Perfection Varnish. Sand between each coat with 220 grade (grit) paper. Remove sanding residue with a rag dampened with Brushing Thinner 2333N.


Mixing Mix base and curing agent thoroughly at the specified ratio.

Thinner Brush/Roller - Brush Thinner 2333N.

Cleaner Epoxy - Fiberglass Solvent Wash 202. Bare Wood - Brush Thinner 2333N.

Ventilation and Humidity Control It is best to paint on warm, dry mornings. Cold weather retards the drying and humidity can spoil the gloss.

Brush Use a natural bristle brush.

Roller If rolling, use a thin nap roller and "tip-off" with a clean natural bristle brush.

Other Perfection Varnish can be thinned up to 25% for spraying applications using INT-2316N Spray Reducer.

Way easier than I thought!


I must say I was a bit intimidated to use a two part varnish but the process was easy and I got a great result. I would recommend a Badger Hair brush when applying.

I can not apply this varnish


I can not apply Perfection Plus varnish without it full of air bubbles. I have tried no thinner 2333N, little thinner, lots of thinner. I know how to apply varnish by brush. I have been doing it for 50 years but I have never had a job turn out so bad. And this was going to be my show case Whaler and now I don't want any one to see it. I am on my second Qt, hoping something was wrong with the batch but the new material is just as bad.

definately buy this product again


used brush turn out great but hard to get without microscopic bubbles


Great Falls, Virginia


bubbles are exasperating!


Tried several ways to apply--roll with foam and tip, brush with foam brush, brush with high dollar bristle brush, brush with chip brush. Thinned or not thinned. Read and re-read directions, emailed for tech help. No matter what, I get a million tiny bubbles. As soon as this last one sets I will sand again and be trying coat #7. Just about out of my second quart and too expensive to keep experimenting. I have seen good finishes done with this product but I will never buy it again.

Just What I Need but a Few Tricky Bits


I purchased this varnish in order to do some tests for a larger project. I found the packaging very good, the mixing easy and brush application very satisfactory. Good coverage, great wet-out and a perfect urethane gloss.Adhesion appears to be excellent and in six months outdoors it has mainatined a perfect gloss so I expect to see it around in 4 years or so.Like many finishes the application and drying take some getting use to and clibration. In order to get the smooth gloss one has to use it at cooler temperatures around 60 to 65. Much warmer and it drys too fast for good wet-out. Next problem is to get it cured before the evening dew gets to it. As a yacht varnish to be used outdoors it is very difficult to find the right "window" of time and temperature to assure it is dry prior to the evening dew. Too early in the day and the substrate is still damp, too late and there is moisture damage overnight. I ended up covering the job the night before to keep the surface dry, putting the Perfection on as soon as the fog cleared and then forcing the drying with IR lamps and covering the forced coating for the next evening. Beautiful!


Yellow Springs, Ohio


great product


This product is great for areas you only want to or can varnish once a season. In this case a teak swim platform. Virtually impossibel to do in season because proximity to waterline.




very shiny!


if any of you have ever used "Bristol finish" this blows it away and doesn't smell as bad, it tacks up quicker and is very durable! lastly gloss like you wouldn't believe!!

Great Product


I talked with Interlux and they recommended this product for a bathroom, and it worked great!!!

Bathroom DIY

Eau Claire, WI


tried Everything, Bubbles come up.


Finally used foam brush and let induce for 40 minutes with 35% thinner.....then Applied with a single brush stroke to each area, brushing Real SLOW and I would not get any bubbles forming up 5 or 10 minutes later....Only got the Centerboard Perfectly bubble free....The deck, which was larger area, Always gave off tiny bubbles, no mater what technique I tried...and I tried them all...I put 8 coats on over sealed epoxy wood, sanding 400 wet between coats, using interlux thinner for wipedown and waiting 1 hour or more to varnish...BUT..the Gloss is Awsome!!..I just have to live with the microscopic bubbles that would form.
