Most any paint you use will wear off and shoe the underlaying color in heavy traffic areas. We bought porch-and-floor paint at big lots of all places for about half of what the big stores wanted. We thinned it with a good paint thinner so it would soak into the wood and act like a primer. Only problem is you can't let it dry for days and then paint over it without sanding it. We put several coats of our primer on the areas inside the doors and then painted the whole floors with the full strength paint. So far after 8 years it shows no wear. Hope this helps. Sam
FWIW, it is possible for linseed oil to get mold in damp areas. My neighbor's cabin has that problem in certain areas. The white primer can show through. As pointed out, you specifically want porch and deck paint. Also, you want to include sand or grit into the paint unless you want a slick surface when it is damp from dew or rain or snow. Porches can be VERY dangerous, especially to old folks with fragile bones.
I always mixed some "porch and floor enamel"(oil based) with Penetrol for a first coat. Penetrol can best be described as a modern day linseed oil. Since they quit making oil based piant with linseed oil as the base long ago. As time went by, and the public believed everything they heard and read, oil based paints fell out of favor as a preference for latex paints took over. Unfortunately, the latex paints were far inferior for decades, but the paint contractor seemed to get the blame. i quit painting at a certain point during that era. The last time I did any painting, the latex paints seemed to have greatly improved, but no wonder since all the research was going into latex paints, and very little, if any, went into improving oil paints. Were i to paint anything today, I'd go to a real paint store, not the paint counter at Lowes or Sears, and ask a senior employee which way to go.
I work in the paint industry and latex paints have changed a lot over the years and are in most cases just as good as oil without the messy clean up. No matter what base paint you pick, Porch and Floor paint come in oil and latex, I would paint both sides of the wood, this is a must in Michigan because of the hard frost, and when you get your primer tinted, have it tinted to a shade of gray. The gray will help you get a better top coat then white because its non-reflective. I've personally had a lot of luck with the Valspar paints and I think you can get at almost every hardware store.

Porch floor in Douglas fir is still available in clear, knot free T & G.
One of the great things about Douglas fir is that it will hold paint.
The big problem I have is that my porch is true dimensional...truly 4 inch wide stuff that is nearly 4/4. I
am going to replace it with the newer stuff.
I am not going to buy it from a super store. I am going to a locally owned yard that has the good stuff. I
am betting it will be pricey, but I want quality.
I have a great friend that restores historic homes...and knows how to do it right. He is crazy expensive to
hire, but is so good that even in this recession, he is booked through 2011, and has turned restorations
Anyway, here is how he does porch floors, and I can attest to the longevity and quality of his process:
1. Get a gallon of boiled linseed oil and a gallon of turpentine, and mix it so you have a 50/50 mix.
2. Using a quality paint brush, coat all sides, including the tongue. Allow to dry, and stack it so it can dry.
3. Get a good quality oil based primer. The good stuff costs about $30 a gallon at Sherwin Williams. It is
worth it if you want to do a good job that will last.
4. When you start laying the floor, paint both the tongue and groove of each board, one at a time, and
put them together wet. This will create a nice seal keeping water out. As you know, water is what ruins
a porch. Yes, this will be very slow, and a huge, huge mess, but it is worth the effort.
5. When the porch is down, finish painting the face with your primer.
6. Finish with a high quality paint. This will be about $30 too.
There will be alot of people laugh at me for posting this, and criticize it to no end. This is how you get a
lasting porch. I know a porch that was laid the same way 8 years ago, and it still looks brand new, and I
am not exaggerating. Of course, it is not the easy way, but it is the way the old timers did it.
