Hello,

I am about to trim out my screen porch (in Wisconsin, full temp and humidity fluctuations from 100 to -30). I milled some clear cedar to use, and the boards are generally 3/4” x 3”x lengths of 8-12 feet. Two questions….

1. Do I need to leave room for expansion at the butt joints? I know cedar is generally more stable, but do I need to leave 1/16th on the ends?

2. This is an area that will receive virtually no direct sunlight. What might you suggest if I want to maintain that nice appearance of the red cedar vs letting it go gray.

Thanks in advanced.

Not enough wood movement along the grain to worry about, you want to keep your miter and butt joints tight. Store your trim or raw wood in the porch for a while so it matches up with the conditions in the porch, before installing will help.

I would go with a couple of coats of varnish to seal and preserve the color of the wood.

end grain to end grain buts, make a beveled lap joint. end grain to edge grain but em tight.
was the wood kiln dried?
for finish, i prefer an acrylic exterior finish like general finishes 450 or sherwin williams A100 non tinted. theyre both very long lasting and i havent had problems with mildew/mold.

Have your say...
