This is part of an earlier post on HT. This may give you some insite.
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.
