What does this look like to you ??

Just started demoing my bathroom and pulled up the linoleum and this is what it looks like. The floor seems solid but I am not sure if this could be water damage. Any thoughts??

Looks like it could just be some residue from the adhesive.

Man thats what I was hoping to hear....Thanks

Awoodfloorguy 02-05-2013 09:13 PM

No problem. Glad to help.

Lyle,

I agree it looks like sheet vinyl adhesive residue. But normally vinyl is installed over a 1/4" underlayment, is that what you've got? What are your plans for a new floor?

Huh? a floor register in a bathroom, wonder why they allow that?:eek:

Jaz, what you're seeing is plywood at it's finest..... My plan for the floor is either 18 x 18 or 12 x 12 glazed porcelain. with ditra of course.:thumbsup:. As far as the floor register goes I guess I'll just live with it.....

JazMan 02-06-2013 01:56 PM

Yes, it's plywood alright. So there's no other layer under this one? Vinyl should never be glued to the subfloor. They used to use -1/4" luaun a lot which is also plywood.

So, if that's the subfloor, is it in good shape? Next, let's start with the framing specs to be sure you're ok for tiles. Need; the size, species & grade of the joists, spacing, and the longest unsupported span. The thickness and number of layers of the subfloor. Might help to know the age and location too.

Don't worry about the floor register, they do that in several states. It's not an issue unless something overflows.:eek:

Nope just plywood...The house was built in 1984 and I'm in Knoxville Tennessee.. And I hate to ask but how do I find out the framing specs? Would a tile installer know this by looking at the floor? Oh and the sub floor feels real solid all over. And if it helps the room is 5 x 8....

Scrape the sub floor clean then put down some luanun 1/4 inch then you have a good floor to work on. you should be just fine putting tile down.
One more thing you need a new WC flange in there.

No! Don't put 1/4" down if you're going to tile. Get the info jaz asked for
and we'll be able to advise you on you're next step.

ABSOLUTELY NOT! Don't do that. 1/4" ply of any type and especially luaun is never used in a ceramic tile installation. Not even if they're not on top but in the 'sandwich'.

The data sheet from the thinset manufacturers' say something like this;

Lyle, I asked;

If there were two layers of ply it would still be 'just plywood'.

You determine how the floor is framed by going under the floor and looking up, take a measuring tape.

I can't define what 'real solid' means. The size of the room doesn't matter.

Took a short break and found 12penny's post. Good info.

What about the spiders underneath my house???:eek:...I guess this means when I get home I'm going into my crawl space.....I'll post back tonight>>> Thanks for this help....

JazMan 02-06-2013 03:27 PM

Measure the joists, might be 2x8 (1.5x7.25), 2x10 (1.5x9.25) or? Would be nice if we knew the species and grade. On center spacing, usually 16". The span is usually from the face of the outside supporting wall/foundation, to the face of the center beam. Need to measure accurately to the inch. Try to find any stampings and read what it says. A camera might help.

Hopefully spiders are dormant, but maybe not. :eek:
