Questions & Answers

Can I use this underpayment to lay tile on?

Can I use this underpayment to lay tile on?
Asked by: Rooky
I searched the internet wondering the same thing. I found a YouTube video by a master installer that shows that yes, you CAN use it as underlayment for tile. You DO however have to properly prep the plywood before use though. Basically, you'll be making a sort of "poor man's" backer board that will work just well and is much cheaper than the actual thing.

Is this underlayment sufficient for an attic floor?

Asked by: K12
No, not to be used as a floor by itself. Minimum thickness for a floor is 5/8" (15mm) depending on the span.

Underlayment (Common: 7/32 in. x 4 ft. x 8 ft.; Actual: 0.196 in. x 48 in. x 96 in.) is rated 4.4 out of 5 by 486.
Rated 5 out of 5 by from It worked perfectly for the idea I had: a cat... It worked perfectly for the idea I had: a cat door for my sliding glass door. I had it cut to 12" wide and just tall enough (79 1/2") to fit in the track of the door. It flexes enough to get it in and out easily and I just store it inside behind the curtain when not in use.I cut a door opening in the bottom about 8" x 8", leaving a 1" strip at the bottom for stability and attached a little curtain of fabric (gathered at the top and cut vertical strips to help block the air but allow the cats to get in and out easily.) Note: this is the sliding glass door between my living room and screened in porch which has a n outer door that is closed at night, so other critters do not have access when I'm using it at night for my cats. They do sell these made out of aluminum and glass that actually get mounted into place and lock, but they are over $100 and for more permanent use. Mine cost $17.10!

Bought this product due to price and availability to complete a faux shiplap project on a wall in our home. The boards are very light and easy to work with which was a major advantage for my wife and I. Boards were secured to the wall with 1.25" brad nails across the studs and everything went great until it was time to paint. The website and also the associate at the store assured us that these panels could be primed and painted with out issue. We bought the Kilz water based all in one primer that was suggested and after putting the first coat on, we found that the primer was actually separating the layers of some of the boards. There are roughly 40 boards on the wall and only 4 of them did this but it caused a lot more work, which eventually led to just completely replacing those sections with a different piece. Not sure why only a few of them separated like that, but I would advise painting before installing if possible just to make sure you won't have this issue.

For me, the thickness fit the job! It covered minor defects in the existing subflooring, and strengthened the feel of the wooden floor already inplace! I would definately consider using again!
