Today I am sharing how to stain a yellow southern pine wooden beam mantel. Updating your mantel is one of the biggest things you can do to modernize your fireplace.

The wooden dark stained mantel was installed  by my friend Jake at Paramount Woodworking (the same person who built the kitchen cabinets for our Police Station Break Room Makeover) and it is the most amazing wooden beam mantel ever.

The yellow southern pine wooden beam is over 100 years old and was in the barn when we bought the house the house. 

The previous owner had renovated a warehouse in the city nearby and he left the southern beams in the barn.

Here is the granite slab mantel that came with the house.

Jake picked up one of the yellow southern pine beams and sandblasted the old paint off at his shop.

Here is the pine wood beam below prior to us sanding and staining.

We used a chainsaw to cut the yellow southern pine mantel to size we needed.

Dark Wood Stain 

I wanted a more warm toned dark wood look so I ordered Rubio Monocoat Stain in a dark stain color called Chocolate.

This wood stain is actually a wood flooring stain and very durable.

 Minwax dark wood stain colors are also very similar.

2. Apply stain (wearing gloves) according to the directions on the can. Be sure pine wood beam is clean from any dust.

We counted over 100 lines on the beam which means this is a really old beam!

Isn’t that really cool?

How does yellow pine stain?

I used a dark wood stain color which was very easy to apply and hid any large imperfections. 

This was actually the sample wood piece below so we could test the color prior to staining the entire wood beam.

  1. Wow, how neat to see the whole process! Thanks for sharing it with us. It’s a really nice color. That was a smart idea to test out the stain on a small piece first to make sure it’s the look you want. That’s a cute picture of your son!

    1. Thank you Brenda! I didn’t want to risk wrecking the beam if the color wasn’t right. My friend (the woodworker) would have killed me if we had to lug another 500 lb beam out of the barn 😉

  2. I love what you all did and I think my wife would too. Would you mind telling me what the dimensions for the mantle ended up being? I really like the thickness and depth of yours.

    1. I am sorry for the late reply, I just found your comment in my trash folder! The mantel is 71 inches long, 11.5 inches wide (deep) and 5.5 inches high.

  3. What are the dimensions of your corbels?
