Loft Flooring

Loft Flooring

Things are getting serious, we are putting floors down!

April came over to help today. We were supposed to have her over for our fifth BBBBq but we already had too many people coming. She’s eager to help and learn so she came to assist with the loft flooring. And since she is now proficient in miter-saw, I put her straight to work!

For the tongue and groove flooring, I found that my local lumberyard, Southland Lumber, was more advantageous than Home Depot. One thing to consider when figuring out how many boards you need is that 1×6 boards are 3/4 by 5-1/2 inches. But it’s 5-1/2 to the edge of the tongue part… meaning that the boards are actually 5-1/4 inches wide when assembled… meaning that I am now one board short (for the mezzanine)…

A couple days earlier, I ordered Tumbleweed’s How-To videos; and let me tell you, it’s something I wish I had done way before! There are plenty of little tips in those videos that, not only would’ve facilitated the build, but would also have helped avoid mistakes and answer many questions.

One example: buy a 1×2 piece of wood that will cover the visible end of your loft flooring.

Tongue and Groove

Since it’s a 1×2, it actually is 3/4 inch thick (duh…) and ends up being flush with your brand new loft floor. It will hide the sidecuts and details of the tongue and groove (as seen in the picture below).

Lastly, you can pick different style of tongue and groove lumber. The style we picked has two different sides. When assembled, one side is flat and flush, the other has little groove details, giving it character. Since the top part will have a mattress, we decided to give character to our kitchen ceiling (that’s also a tip from Tumbleweed’s How-To videos). Unfortunately, the side supposed to be flush isn’t so flush so we might have to sand it all…

Once you get the hang of it though, it’s not that complicated. You put glue down (we use Liquid Nails), slide the piece of flooring into the previous piece, make sure it’s tight and nail it in place. The toughest part is driving those nails right onto the tongue part of the flooring without splitting the wood. You finish the nails with a nail punch so that they are completely hidden. We were done flooring by the time the moon rose (about 3 hours).

I have family visiting from France for the next couple weeks so I’ll put them to work too. They shouldn’t come and visit me while I have this project going on! Therefore next BBBBq will be family based only. Stay tuned for more progress and as always, thanks for reading.

That’s all folks,

    Is the tongue and groove you used on your loft non tapered? It looks like it but hard to tell. Thanks!

      I’m not sure exactly what you mean, but one side of the lumber had a bevel while the other didn’t. We put the bevel facing down because it’s what’s visible from the kitchen and the flat side facing up. If we had a bevel on the top of our loft, it would just end up being a dust trap. I hope this helps.

    What kind of flooring is this and where’d you get it?

      For our loft? It’s just 3/4″ pine tongue and groove that we got at our local lumber yard

    Hey guys. Do you know of a downside to not framing the loft flooring into the wall? I’m thinking about just extending the wall 3/4 inch and not using the 3/4 ply or shifting the loft floor into the wall.

    My dad is visiting to help with the framing in limited time and I’m unsure of the loft flooring I want to use so dont want to rush to a decision and need to start on the dormer wall. So… I’d like to build the walls and install flooring later (not under the walls).

    Do you have any advice? Thanks!!! your site has helped guide me this far and things are getting more and more complicated…

      I think you’d be fine. You just have to make sure that everything ends up at the same height

    Love your blog, these tips are very helpful. I am starting my build here in Orange County , what kind if siding are you planning for tiny house ? I am actually using SIPS for my build.

      Hi Mario! Sips are great! Sometimes we wish we had gone that route. We are actually doing reclaimed wood for our siding. Post should be up in the next week or so. Stay tuned and thanks for reading!
