Thought I would throw this out there to see what experiences members have had with the various poly's out there. Covering our cathedral ceiling and other indoor surfaces with it. Wondering about things like number of coats, yellowing, and so on. I can read all the manufacturers stuff, but I'd like to read some real world experiences.
Thanks,
Gary

I used a $60 HF airless sprayer and sprayed this on white pine tongue and groove. I did one coat on the back and flipped immediately then one coat on the front, let dry for 5-10min then did a second coat on the front. No sanding or any surface prep. I could have sprayed a whole pallet load of the boards before lunch if I had enough saw horses.
Idk how it's going to yellow or last because I just did this about a month ago. The satin looks like you didnt put anything on the wood, just what I wanted.
I also did a few doors with the same finish but sanded with 400grit between coats. I did this because I wanted the finish to be smooth to the touch

Oil-based finishes usually age to a yellow color cast and more so when exposed to direct UV light. Of course oil-based finishes are also yellowish in color to begin with. I prefer no color change to be caused by my finish and prefer to use water-based clear finishes.
I normally apply thin coats and allow them to dry thoroughly before recoating. With a water-based finish, some light sanding with fine sandpaper is usually required as they tend to raise the wood grain, however it is my preference. Water-based are also less odorous and don't contain the harmful solvents.

Unless you need the moisture resistance, I would go with shellac instead. It's a natural product and a LOT easier to apply, and IMO looks a lot nicer (I don't want my cabin wood to look like it's dipped in plastic).
When I do use polyurethane, I have had much better results with Varathane than other brands.

As a guy that has used a lot of topcoat while operating a custom woodworking shop. Varathane brand polyurethane is my choice. I have used both water borne and petroleum based. Both work great. But I believe that the petroleum based product goes on smoother, easier. I have heard folks say polyurethane looks like it is dipped in plastic. I don't believe that. It is very durable and provides the best moisture resistant qualities of any topcoat. As for yellowing the wood. Pine will develop a yellowish tint through the years that is caused primarily from sunlight, UVs. And personally I like that look. Most important for TnG is to finish before you install. Wood moves and you can notice the difference when it shrinks a bit in the dryer months.
For our TnG pine boards I will spray the back and then the front. And reapply to both sides again. Using a green scotchbrite pad between coats. It takes a little more time but I want the best I can do.

Fwiw, Ive had plain unfinished t&g interior yellow even on the dark side of a room. Didn't know until we took down a picture  ; did take years though.
I like the yellowing/mellowing but wonder if maybe the Varathane would slow the process?

I used Varathane's exterior satin poly for our porch roof and it looks perfect. I am trying to do an end around on having to do 4 coats. Obviously, an interior poly doesn't have to stand up to what an exterior has to deal with. I also wouldn't mind not having to spend $129/gal plus 15% HST (I'm building our new camp on the Miramichi River in New Brunswick, Ca.) I've done this sort of work for many years, so I'm frankly not really looking for how-to advice, just brands that have worked for you.

I have always had the best luck with Varathane do my interior woodwork, including cabinetry etc. I have quick a mix of woods & finishes (rough cut to fine) in my cabin. I will however highly recommend that using semi-gloss is preferable for making cleaning easier, flat etc catches dust & cobwebs etc like mad and with cathedral ceilings it's a (grrrr). They do now have formulations with UV Blocker usually marked on the label somewhere.

My preference is Minwax Polycrylic water-based though I sometimes use the Varathane water-based equivalent. No matter which I use I never use a gloss finish, unless a customer insists. For my own items I also never use semi-gloss for anything; I use satin finish. That never looks like a plastic coating.
I like natural unstained wood finishes, but I quit using them outside for virtually anything decades ago as they require more maintenance than I care to exercise. Indoors I have assorted wood wall, ceiling, and floor finishes mixed in with stone, tile and drywall.
