Porch Floor - attempt #2

Maybe the text will show up this time?

I am getting ready to put a new porch on the front of our house and I am trying to decide on which type of t&g flooring to put down. We want to use t&g to avoid having the porch "feel" like a deck.

The details: The porch will extend 8' from the front of the house and be covered with a roof that overhangs the porch by 2'. Location is Central Ohio. The porch will be added to the west side of the house. Most of our rain comes in from the west. The floor will be painted. The porch floor will be approximately 15" off of the ground.

I can get PT flooring, but I am worried about the boards shrinking. I do not want any gaps between the boards in a cpl of years!

I can also get untreated t&g and treat it (with what I'm not sure of) prior to painting.

One more question/comment: I had thought that in order for rain to run off the floor "better" that the flooring boards should be installed perpendicular to the house. In the places I have looked, I have seen drawings with the boards running parallel to the house.

Any thoughts/comments/ideas on this and any help on a wood preservative that has worked well for you would be greatly appreciated.

Hi Mike,
The forums had a glitch but there now working properly.
I'm a bit unsure of your 'feel of a deck'. If the deck boards are installed On 16" centers it is quite solid.
Anyway, since your porch will be covered you will probably want to go with douglas fir if you can find it. I've seen T&G Cedar but that will probably be too soft for an entryway.
You could pre-treat the fir with cuprinol as long as your paint will cover and properly adhere. You'll want to ask and read all the labels first.
You bring up a good point with the running direction. There are two schools of thought on that:
1) parallel to the house offers slightly better footing when entering the area,
2) perpendicular will direct water away from the house only if built properly.
Either way works okay as long as it is built with just a slight grade away from the house. A one inch drop in your eight foot porch should drain water properly and not be noticeable.
I hope this all helps some,
Go Buckeyes,
