I have to stain/seal untreated pine tounge and groove boards that will be up inside of a cathedral ceiling on my deck roof. I looked into the Minwax PolyShade but it says interior only, I also looked at Cabot and it says the same.

Time may not allow me to do two seperate products. Someone standing in line at the home improvement store told me that they used Sikkens and it has lasted 12 years and still going, I haven't looked into their product yet. My father used Sikkens on his deck but it was more like a pigmented paint although it was a great product. I'm looking for more of a pigmented stain not to hide the grain of the wood.

What do you suggest?

I don't like using a tinted poly on raw wood. Unless you are spraying it on, it's difficult to not have any lap marks.... and it must be applied evenly to keep the color consistent with no runs, drips, over laps or missed spots - it doesn't touch well at all.

What do you want the finished product to look like? If you want it slick and shiney, I'd use an interior stain and 2-3 coats of poly. Interior stains/poly whould be ok because the wood isn't exposed to the elements. A house or deck stain will also work although it will produce a different finish. These types of stains come in translucent, semi-transparent and solid. The solid stain resembles paint.

If I was to stain the ceiling after installation, I'd lean towards using an exterior stain. If I could stain it before installation, I'd use an interior stain and apply atleast 1 coat of poly. The poly will prevent finger prints and other stains from being a problem.

Cabot does make a product that would likely work for your project.Cabot makes a lot of products and many Cabot dealers only carry some of them.you may have gone to one that did not carry this line or the help there wasn't knowledgeable if it was a big box store.

Frankly I'm not sure with a product similar to this one that you need to use poly behind it.In your case the surfaces are not exposed directly to weather.Poly either interior and especially exterior will add significant expense and effort.All you need to do is give some protection from minor water and humidity exposure.

Ya, a lot depends on the look you are after. If you want it to be smooth and slick looking, kind of like furniture, you would use a stain + 2-3 coats of poly. If you just want enough coating to seal the wood from humidity and such, 1 coat of any exterior stain should do fine.
