Will this floor support tile?
 
Hello all, forum noob here :)
So I am thinking of tiling my kitchen floor and I have been told I need to check my floor for deflection. I'm not sure how I would do that :confused1:. I can tell you currently the floor joists are 2x10 spanning 12 feet unsupported. The subfloor looks to be 2 sheets 3/4" plywood. Is that enough to support tile?

*edit* forgot to add that the joists are 16" on center

Not sure what others on this forum think of it but you could try:

You'll need to find the species of the lumber your joists are made from. Usually it is ink-stamped on the side of the joist.

Hi Olsen,

Your joist set up is stiff enough for ceramic tiles as long as they're in good shape. The two layers of plywood also make that deflection plenty good for ceramic tiles.

All you need is to chose a tile backer or membrane and then tile away. Please come back for more detailed info as needed.

Bob,

Although I know and like John and I am on the site too, It is rather low class to send DIY Chatroom customers to other sites. Why didn't you just answer Olsen's question?:whistling2:

thanks for the replies. I did check the joists and they've been in there since 86 I think the ink has faded :laughing:. They do look a lot like yellow pine though and they are in good shape.

OK, sounds good. SYP (Southern Yellow Pine), is very common and one of the stiffest species of wood for joists. They normally use grade #2, but many other grades are available and is why I ask for the grade, but rarely can the people read it on the lumber.

What's next?
