I have searched previous posts and unable to find a question/answer. We have 5/8" inch engineered floors. The manufacture says to use L or T Cleat 1-1/2" to 2" long. However, nowhere does it say which gauge to use, 16 or 18. We are about to purchase a nailer and want to make sure we get the appropriate gun.

Also, we will be doing the upstairs in a 10" wide, 3/4" solid oak as another project . Figured i would ask what gauge to use on that as well.

Lastly, does it matter, L or T Cleat?

Thank you!

16 Gauge cleat for the solid wood flooring. Contact the manufacturer of the engineered flooring and ask them what Gauge to use.

Contacted the manufacturer. They said the gauge does not matter so long as the PSI is set correctly on the compressor.

That seems counter intuitive to me given that the nail size should be proportionate to the floor size, tongue size., etc.

Either gauge will work. The important thing when buying a nailer is does it have the correct shim for your thickness of flooring. You need a plate the right thickness so the nail will be positioned to set the nail in just the right place for each thickness of flooring that you use. Not all come with different shims, but you may be able to purchase the one you need when you buy the nailer.

any recommendations on the most versatile nailer?

As long as you will be buying 16 Gauge for the solid flooring give it a test try on the engineered to see how it works out. Nailer prices come in a wide price range. Harbor Freight has one for $99 and top of the line will run over $700. If you buy a good ($$) one you can sell it when you are done with it.

Thank you. I bought a good one with the plans to sell afterwards.

Have fun! Please post some pictures of your project.
