Floor Framing 20 x 30 Shop

I am building a 20x30 shop and its time to frame the floor. I am using 2x6 treated lumber for the frame so that it will be weather resistant and bug resistant. Because I dont have a nailgun I am using 3.5" torx screws and hammering galvanized nails as well. If you are looking for how to build a shed floor this is the place for you.

I was thinking the same as your neighbor, plywood perpendicular to the joists is stronger. Now your extra blocking will really stiffen and strengthen the floor.

[@sethcraftworkshop]

Yes! This floor is super strong now. 3/4" ply is on top!

2x6 with the beams under mid-span is fine. I have the same layout with 2x10 spanning 10 ft. I like your design better. More economical in the end I think. Nice work.

[@sethcraftworkshop]

When doing my research I found that a 2x6 can have a span of 7 feet so I figured 55 inches should be more than enough support for this size building. My atv shed has 2x8 and it has had no issues with the atv and lawnmower.

Does that moisture barrier let water and air through?

[@rashellyohn5128]

When you did your toe nailing with a 3" Phillip screws, it went right in. When I try, they only go in so far and start to strip out.... I have to use a bit first. Its frustrating.

I'm getting ready to build a shop... (slightly smaller) Your video's are fantastic. What part of the country are you in where you need such a moisture barrier? - thanks!

[@sethcraftworkshop]

Nice! A shop opens up so many opportunities. I installed a shed years ago without a barrier and had issues with mold. Once I installed the plastic that went away. I am in NC and it rains a lot. But the ground moisture is worse than the rain.

[@BADBRYZ]

How funny, I'm in NC too (S.E.). That's why I asked about the moisture barrier. SO GLAD I found your vid. I'm definitely going to take the extra step for that. I can't wait to see your shop when it's done. KEEP US UPDATED with videos!

Could I Get A Materials List For This Project ? Only For The Floor Framing. Number Of Joists And The Lengths Of The Joist Etc.

[@sethcraftworkshop]

I actually have not made a list for materials. This video is the only documentation that I have.

[@MikeSheasheaDtree]

no offense, but all those mistakes you pointed out, were easily correctable...I guess it's personal presence , but I would have corrected them. That said, I am watching because, I am getting ready to build a 12 x 14' 6" . Your videos are very helpful, though I am in SE AZ I am going to put the vapor barrier, we have monsoons AND termites.

I think it's important for us KZbin's to point out the mistakes made. I'm one of those get a project done type of people. Running 4 channels can be time consuming and there are times I don't get as perfectionist as I could on individual steps. That being said, I definitely recommend getting your build as perfect as possible.

Bubble foil?

[@sethcraftworkshop]

Actually 1" ridged foam.

[@gshumn]

Watching you gives me a headache. You have more money than actual knowhow

[@sethcraftworkshop]

Explain what the issue is? This frame seems to be built well enough for my needs.
