Crap paint stripper, vaguely boaty.

Brain wave. Caustic soda. Oven cleaner. Wife has confirmed she has some. I'll hit it with the heavy stuff tomorrow morning. Carefully of course with all the ppe. Fingers crossed.

Be interested to see how oven cleaner works, I was wondering about using oven cleaner on some old varnish the other day as I had run out of Nitromors, then found I didn't have any oven cleaner either so still have a bit of varnished wood to strip.
 
Woops, applied oven cleaner and the areas of bare wood went instantly dark chestnut. Panic stations, washed off quickly but wood stayed that colour. Fortunately I only applied to a smallish area to test it. An hour later i had scraped the lacquer of the area and sanded down to almost get rid of the discolouration. Then applied oxalic acid and magic happened. Back to oak colour again. Big sigh of relief. Maybe a reaction of the oven cleaner with the tanin in the wood. Don't really know but I won't be doing that again.
Ok so another day passes and now there's only the top and bottom area of the door left to do. Another half day tomorrow and it will be ready to be final sanded before coating application starts.

About eight years ago the law was changed and you can’t buy paint stripper that actually works on a retail basis. The original formula is only available to professionals. I loathe this modern society we are in, you can’t buy rat poison unless you do a course. We really are in nanny Britain.

Had to Google exactly what that is. Next search was the difference between varnish and lacquer.
Very basically lacquer is a lot thinner and more solvent based so it penetrates the wood and is sprayed in very thin coats (like spraying and car) drying fast compared to varnish.
Varnish naturally has resistant uv properties.
But then comes along waterborne lacquer suitable for outside use
Throw in a little polyurethene and .......
What a great job you have done greeny .looks like a new front door/sidelights
Do you have a before pic?
What are you going to coat it with?

No photos of before, I wish I had done now.
As for the coating I'm not sure. I have several tins of "varnish" available to me in the shed, all in good order and maybe suitable. Rather than go for something that will be just as problematic in the future, I may just stay simple and use one of the clear satin varnishes with UV protection.
The door is in full sun all day (when it shines).
Thin it for the first couple of coats and then another couple of coats on top. I don't want to put too many coats on because the colour will get progressively darker and I like the light oak. There's 2 tins in there that fit the bill. One is water based the other is oil. I've used them before and been happy with the results.
Otherwise it's off to B and Q or somewhere but doubt I'll use anything fancy.
At least that way it will be easy to rub down and overcoat, or strip next time without all this pallaver.

P.S. It looks better in the photos than real life I can assure you but I am pretty pleased with the progress and results given the issues with the lacquer.
 
The nice thing about varnish is that it's probably one of the easiest things to remove further down the road.
 
Job almost finished. It just needs the final coat now and that's it. I'll do that later in the week once the weather has warmed a bit.
