I used this product on the transom of a 30 foot fiberglass sailboat. The area was not large (maybe about 20 square feet). I used a 4" foam roller to apply the urethane and tipped with a brush. The results were better than I expected but I did have a couple of areas where there was some orange peel. I was able to correct this after the paint was dry by sanding with 600 grit wet sand paper wrapped around a wood block. Hope this helps. Bob in Tennessee.

Answer

Like any two part product once it is mixed you must use it. But other than that is goes on easy and looks great.

Answered on 09/04/2011 by ROBERT MCMULLEN

Answer

This product is tricky to apply on verticale surfaces becasue it is thick and it sags. Horizontal surfaces are not a problem. It flows out and creates a clear high gloss finsih. I used it on a cedar mailbox post and a redwood light post. The finish still looks like new several years later. I solved the sagging problem by rotating the 4 sided pieces being finished until the finish set and I applied it as thin as possible. I also soaked the wood with CPES before applying the finish. If you do end up with sags,get out the sand paper and apply another thin coat. Great product that I would use again.

Answer

I'm an amateur, too, but my application is different -- painting a flat, horizontal span of MDF, so I can't speak to how well it stays put on vertical surfaces while wet. I can say that it is easy to mix, not too stinky, wets out pretty smooth and shiny on its own, and after curing is the most incredibly tough paint I have ever seen or could ever imagine -- impressive. FWIW, it can not be sprayed without breathing apparatus due to toxicity of the mist, but is safe when applied as you have decided to do. Wear gloves, though -- it's probably not the best stuff to get on your hands, but even if you don't care about that, it's not the easiest to clean off them, either, heh.

Answer

I've only used the varnish. For varnish, I spray (HVLP) for a smooth finish with no brush marks.

Answer

I'm currently experiencing about 5 years life in full sun on a wooden deck with the Epifanes applied over epoxy. In less than full sun it's longer but I can't say how much because I haven't had a finish fail ther as yet. I've not tried it on carbon fiber so can't say with confidence on that part of your question.

Answer

I don't know. I use it in gloss on my deck (over West 207 epoxy base).

Answered on 04/25/2015 by MICHAEL LAUER

Answer

There is a separate semi-gloss product with the flattening agent premixed. I was told to do the first x coats in gloss (I think I did 5 or 6) and the final coat in semi-gloss. If I was to do it again, I would do two coats of semi-gloss with different lap zones. I missed a couple spots and they stuck out like sore thumbs. I tried to touch up but now there are lap marks and the touch-up semi-gloss sheen is different than the final coat. There are a few gloss stripes at the lap zones between boards that are too narrow to touch up. Overall the project (interior wood floors) looks good, but the touch-ups bug me.

Answer

I've not actually tried this so O would recommend trying it on some spare part first. Interlux makes a flattening agent for their two part polyurethanes, part # YZM914KIT/QT (west marine # 6862270).I have used it on the decks of my Blackfin with great success. Hope that helps.

Question

Can this 2 part finish be applied over an existing traditional varnish finish?

Asked on 05/27/2018 by izmo from FL

Top Answer

No. 2-component products generally destroy 1-component products, or will suffer from the lower adhesion of the 1-component product.

Answer

According to Epifanes "Suited as a indoor and outdoor varnish system on its own on non-working (ply-)wood , as U.V.-resistant and protective finishing coat on epoxy resin or as an intermediate -adhesion- coat on wood treated with epoxy resin prior to the application of a one-component varnish." So short answer is no. Michael Lauer

Answered on 05/27/2018 by michael

Answer

I have never done so, but I would think you can, provided the existing varnish is sanded down to only a thin layer over the wood. At that point, I think any negative reaction would be minimized to a negligible status. The value of this two part varnish to me is its resistance to the Florida sun. So, even if it turned out I had to sand to bare wood, I would do so. But I would also try it on a small area before undertaking a full sanding job. If you can, let me know what you decide and how it turns out. Rick Spinner 7402 Palmer Glen Circle, Sarasota, Florida 34240 - text and tel:

Question

Does high temp affect open time? Should I thin the paint more? How will I know when thinned enough?

Asked on 07/03/2015 by Steve Flinchbaugh

Top Answer

I live and work in SW Florida, this time of year it is 90+ degrees during mid-day. I try to be done by noon or so to avoid the worst of the heat and sun. As such, I add thinner until the mixture drips off the brush, not runs. This seems to allow sufficient flow time before setting. One nice thing I have also discovered is that once a coat is down it is relatively immune to any following afternoon rains! The thinner works very, I usually buy 500 ml when i buy 1000 ml of urethane and I always have left overs. Good luck

Answer

I have used this product with a HVLP spray system. Pot life is 3+ hours (around this per directions) but I haven't has it sit in the pot for more than 2 hours because I'm done with my largest batch by then (more than 1 kit but less than 2 kits in my largest batch). I have sprayed between 50 and 100 degree weather (in shade outside with low wind). I have not noticed any difference in pot life within my timeframe). I thin to my sprayer spec. As I recall that comes to roughly 10% by volume but I use a fairly small needle. I've noticed the surface doesn't quite settle to mirror smooth if sprayed with too little thinner. By the way, just before spraying the next coat (after 24 hours) I do a quick wipe with brush thinner. This gives the prior coat a nice tack and removes any dust settled on the surface. I haven't applied by brush so cannot advise on my experience.

Answer Question

Question

Three Questions (maybe more) 1. Is the 2 Prt Urethane good to protect epoxy? 2. Would the regular Epifanes Clear Gloss Varnish be better? 3. What is the best clear to provide UV protection for epoxy?

Asked on 06/01/2012 by jim pennock

Top Answer

I use the 2-part urethane to protect epoxy. I've had very good results using this over West Systems epoxy using the Special Clear Hardner on cedar decking. I've had poor results when I didn't apply to all 6 sides. Any break in an edge will cause the underlying wood to deteriorate and the epoxy and urethane top coat will lift. This is the case regardless of which top coat you use. Also remember to let the epoxy cure fully (a week or two depending on temperatures), sand, and then wash the epoxy to remove any surface wax (from curing) before applying any varnish. My opinion is that the 2 part Urethane is tougher than regular varnishes. My recollection is that I get 3-4 years life from varnish applied over epoxy and 5-7 years life from the 2-part urethane over epoxy (in the same location). The 2-part urethanes are more expensive so the savings is in labor by having reduced maintenance frequency. Also, I have yet to have the 2-part urethane break down in areas where the sun isn't strong though I have had varnishes break down. As to what is the best clear... I don't know if you're talking brand??? I've used Epiphanes and I've used Interlux Perfection. Similar results though I believe Interlux has changed its formula since the last time I've used it.

Finewoodworking . com performed a test in four US states using several varnishes and Epifanes came out on top. This article, that my neighbor provided me, convinced me that the UV protection of the Epifanes varnish is superior. I use it exclusively. If you follow their thinning instructions, you won't be disappointed. David
