What would be the best to fasten 3/8" plywood for underlayment over my 3/4" T&G plywood for bith ceramic tile and engineered hardwood flooring.

I have a framing nailer and last floor I did I used 6P Ring shanks and did not care for how it set the nails.

I was thinking about getting a 1/4" narrow crown x 1-1/2" stapler to attach the underlayment?

What do all of you think?

As long as your not plannin to set the tile on the plywood....

I like narrow crown staples, lots of em, it will not come with out a fight.

When I get to tile, I plan on using Ditra over the plywood.

Bump - Any other opinions?

I read a study on screws vs. staples vs ring shanks and the results weren't conclusive.

My vote: narrow crown via air nailer. Every 4" in field and every 2" around perimeter. Each staple is like two nails. Each staple footprint is also smaller than a rink shank head or screw head. This makes for easier leveling and filling if yr doing something thin and telegraphing over top, like vinyl. But for tile, it's not an issue I guess.

Brian, I'd not use staples with 1/4" crowns.

IRC Fastener Schedule, 602.3; Floor Underlayment; Plywood: Staples shall have a minimum crown width of 7/16" except as noted. The noted exceptions are 1/4" and 5/16" plywood and 1/4" - 5/8" particle board.

No narrow crown even though I am putting 3/8" over 3/4" T&G Plywood?

BTW, where did you find that information.

A bunch of narrow crown staples in 3/8 is not going anywhere.

I would use a medium crown myself, but if you dont have a medium crown I would think narrow crown would work as long as they are long enough and you use lots of them.

International residental code (IRC) is code in alot of states. I got my code book on Amazon. You would probally want to make sure that you get the one and two family dewllings version. And not all states that use the IRC use the most current version so you might want to find that out also.

Look at my post again. The IRC reference section and para. is stated right there. ;)
