Hi,

Finishing a basement wash room bath. Washer,Dryer sink and toilet, no shower.

The floor must be 2" to match up with the rest of the finished basement.

I am using vinyl for the floor. The room is approx. 7' x 10'.

Therefore, I will have a small piece of flooring left, 3' x 7' after I install the 4' x 8' sheets.

My questions are :

Is it better to use 2 thickness's of flooring plywood so that the small piece of flooring is covered by the 2nd top piece?

I would use 5/4" pressure treated decking first followed by 2 pieces of plywood, then luan plywood for the top. Then vinyl.

I plan to rent a luan stapler, should the luan also be glued or is this over kill?


Thanks:o:o

Deck boards are really only 1" thick. I would use the deck boards, perpendicular to one another then two sheets of 1/2" plywood, overlapping joints. Everything screwed together. You can use adhesive but you will never get it apart. I wouldn't use luan, besides it is only 3/16" thick.

Hi,

Thanks. The Luan would be used to stop any telegraphing through the vinly floor.

I believe Luan is utilized under most vinly floors for that purpose, if I'm correct??

I would use 1" decking and 2 pieces of plywood with Luhan to get to approx.2"

The 1" decking would be spaced at 16" centers.

Everything, except the luan screwed together.

I guess luan is all right for vinyl just don't use for ceramic. Get some trowelable Liquid Nails and glue luan down, then no fasteners necessary. No fasteners going to do much anyway because it is so thin and soft. Running deck boards perpendicular to one another will help flatten floor.
