Question How to lay down plywood?

Hi all,

Simple question and process just thought i would ask the pros.

What is the best way to fasten the plywood to the floor to minimize torquing, end-bends, etc. I am putting an underlayment and laminate on top. Yes i know laminate is an "iffy route" but it was the cheaper/nicer looking route so please no comments on how laminate is a bad idea lol.

Any suggestions on the best way to lay laminate down are greatly appreciated though!!


and as always.....>>>>>LOVE THIS>>>>>>>

I placed mine with 2 coins separating them to keep the from rubbing during frame torque. Then I used a self tapping 2.5" Deck Screw especially along the edges. Worked out for me.

I used the tek screws with wings. The tek screw has a drill point that
drills through the plywood and the metal and the wings ream out the
plywood to allow the screw to pass through the plywood and get a better
grip on the metal. Once the drill point penetrates the metal the wings
break off and allow the self tapping screw to thread into the metal.
Threads on the screw are machine screw threads.

I have seen the work liquid nails tossed around. Would i use that to help the plywood stick to the metal?

Don't

Plywood has no place in a floor. Did you not learn from the plywood you removed?

Now if you must install the crap in the floor of your bus, You need to read build threads on how others did it.

Some did a better job than others. JakeC did one of the best free floating installs.

No screw should go through the plywood and directly into the steel floor.

Doing so will cause condensation to form on the heads of the screws from the temp changes from inside to outside of the bus.

The moisture from the condensation will cause rot, mold, and rust.

liquid nails will do nothing but make a mess.

Nat,

Do you have a link to JakeC's thread?

I am using similar plywood to what Eastcoast is using, 3/4 in right?

I have seen others who run 2x4's along the length of the bus and put insulattion there but they have to drill the runners through the floor anyway right?

Also using a really good underlayment on top of plywood.
