Question about finish

I have sold my cedar table. I used an indoor/outdoor spar urethane on it. I believe three coats. I have always kept it indoors, they use it outdoors and after this spring and summer I see greying around edges and in spots. What is the best finish I can use to keep the cedar the nice red it was? And how deep will the greying get if not corrected now?

Not really an accurate answer, but I have had pieces of cedar for 10 years, waiting for the right project and
the greying seems to go about 1/16th to 1/8th of an inch. The wood underneath seems to be projected
and still gives off that cedar aroma and has the same color. A exterior spar urethane might help on the
protection, but I have not had any exterior projects of this type.

If you find the answer to preventing ERC from going gray when used outdoors, you’ll make a fortune. Bottom line is it’s a reaction of the wood to UV in sunlight. It’s only the surface as mentioned by Gus but it will turn…

-I was wondering if the , supposedly, UV resistant finishes help with that too. It is sad knowing that lovely patterning won’t be around long.

I think when a piece is outside red barn paint works. LOL However to show off that beautiful wood I know the allure of spar poly. Bad news is every once in a while you have to sand it off and recoat it. But you only have to do the top of the benches and table (at least that’s all I would do…) and it doesn’t take that long. Best thing is to put the table in the garage or barn etc. for the winter and cover it up. I never do naturally, but it is good advice.
