Re: U/V resistant/clear epoxy vs OR over top varnish - how to go?

For the first parts I did on my boat (some trim around a hatch) only have about five years on them. But they have absolutely no signs of peeling, or clouding, or anything, other than a few scuff marks from normal boat goings-on. However, I don't have a lot of woodwork, so it's a pretty small sample size.

Never forget them. Do something to prevent it from happening again.

Re: U/V resistant/clear epoxy vs OR over top varnish - how to go?

Ive been researching how to treat deteriorated wood and end with a clear finish. I've been told that all epoxies have no UV tolerance and if covered with a clear finish, the system will total fail. Also that poly laid over epoxy won't set. Does an epoxy treated then clear finish need total sun protection?

I am going to use Ephesian varnish which is UV resistant over the epoxy.
Here is a link to west systems varnish over wood.
WEST SYSTEM | Application Techniques - Varnish over epoxy

I applied an exterior grade polyurethane on some handrails, peeled off after a year. They did look great for about 6 months, then dark spots started to show up to ruin the party.

Re: U/V resistant/clear epoxy vs OR over top varnish - how to go?

I own a Teakey and before I became a 'reformed varnish-aholic' the 'best' and longest lasting was a scheduled lay-up of various coatings:
wood encapsulated on all under surface to prevent moisture migration --->penetrating epoxy on surface to be 'varnished'---> 6-8 coats of oil based varnish (color coat) --->6-8 coats of urethane based varnish (with UV absorbing) compounds (top water seal) ---> 2 coats of Interthane (Perfection) 'Clear' as the final coat for 'ultra-gloss'. The MOST important is the UV filter to prevent destruction / weakening of the surface wood cells. Second most important is to seal/encapsulate to prevent MOISTURE migration through the wood. Those two issues are what destroys the bond between the wood and the 'varnish' and causes 'lifting' and 'the black staining'. Even with such a 'hodgepodge' of layers/coatings ... the average 'best' I could get out of them was 5-6 years and then had to do a total strip-down --- ugh!

For simplicity and still for a close to 'varnish-like' coating is simply to use a modern 2 part base + 2 part 'clear' ... and typically get 10-12 YEARS with simple quick 'clear coating' every 2 years ... and a quick power-buffing with 3M "Perfect-it" in the 'between years'.

My preference for the 'modern' coatings is Honey Teak (signaturefinish.com), then Bristol Finish, etc. These are quite easy to 'repair' if you dont let water penetrate into the wood. If you want a 'museum grade' finish that can be hand-rubbed or powerbuffed to a dazzling gloss (just like you do with a 'prime' varnish job), then I suggest Honey Teak. HT has a very high learning curve, is VERY expensive, but when you amortize over the total life, it turns out to be the very cheapest.
(I really hate CETOL, even the butt ugly 'Cetol light', etc. as its hard to repair and color-match ... and when built up it CRACKS like crazy, requiring a total strip and re-do)

If you want to see what Honey Teak looks like after 10 years ... go to: post #32 on Teak Oil vs Varnish vs Cetol

Did you mean Epifanes? Ephesians is a book of the New Testament.

Re: U/V resistant/clear epoxy vs OR over top varnish - how to go?

Anyone else have negative or positive thoughts about Cetol?
I welcome emails as well.
I live in New England and just bought an old Quickstep.
The varnished areas are shot and I plan to use a varnish remover and sand these down
to bare wood and then add Cetol. Open to another product.
Also curious about Zip Strip vs Circa 1850 Heavy Body vs 5F5 stripper.
Thanks,
David

Cetol "Natural Teak" is my choice after using many different makes of Varnish.
