have osb subfloors that squeak on 3 story duplex
 
one unit on top of other. the subfloor is osb as is the 2nd story stair is osb. I was going to tile the living room, dining, , bedrooms 2 and closet. What type of layers of "floating tiles" would you use and size of tile and tp would you use on osb so it oesnot crack etc. Would you use a concrete or bonnmite on any of these rooms about 980 sft. it hs to match existing tile in bathrooms andkitchen. thanks

You're supposed to use a concrete board before laying tiles. Since your floors squeak, you're asking for trouble if you lay tiles without the the boards.

Creaking = Flexing = Cracked Grout

Will you please re-write your questions so that even I can understand what you thinking of doing and with what? :wink:

USE Ditra... it is better than cement board... it can handle minor unstable subflooring... but if it is real big movement... nothing will help and you need to fix it first...

osb new subfloor in lr, dr, bdrms, hall, study
 
1. i put more wood screws in osb subfloor (i tried toget the general not to put it in) every 4 inches or so for creaking and some expansion joints in between sheets which it didnot have b4. 2 baths and kit and laundry rooms have floated tile there now. unfortunately i didnot have the rest done cause this really bad tiler who used unknowable, workers wanted more money and physically threatened me and the project with a hammer - called me a "D B etc." , after he got more money. had to get rid of him with more money. took him about 3months to do it.
the general didnot do his job either overseeing any of these contractors.
2. this is an upscale rental duplex. this is 3 story duplex with a basement as one story. on unit on top of each other. and u can hear people walking.city views. 2 bdrm, 2 baths. witha outside balcony that slo crunches and makes noises when u walk on it with the balcony coating.
3. want to tile remaining 1st floor unit whch is on top of basement . The new tile will have to match the existing tile level heights which is not 100% even or level so just using backer board wont work. I went to the Mapei , etc website where they give different layer, cake recipes for preparing the mortar beds, or plywood depending what you have as a subfloor which i have is osb which cannot be removed since the walls are on it, etc. i have gone to the tile institute and looked at thie rsandwich diagram. if u have nay recommendatons on how to lay the tile please contact me, I see by floating the tiler an not using a concrete or other epoxy floor covering. thanks
4. if tile is not recommended since most of you are experienced contractors I ws going to use perhaps engineered wood, laminate which may not last for a rental.
any way. thanks. hooe that clarifies.

want to float the tiles rather cement board
 
1. whats ditra?
2. i have exising tile that is floated in the bathrooms,kitchen, washer rooms so these heights have to be matched in the remaing flooring ofthe dining room, hall, living rooms, bedrooms, study. since the existing tiled rooms the tile is not even and the osb is not even either will float the tiles.
3. i was/ may be considering using laminate in the bedrooms but the transition from the rooms would be a nite mare. also looking for good qualified floor/tile person to do the work.
4. having osb as a subfloor takes extra preparation as er manufacturers layering to do tile.

When you say floated, what exactly does that mean?:confused1: Describe the process.

ditra is those orange thick plastic membrane sheet...

they are the best for tile installation, although more expensive, guarantee success...

osb,oriented strand board will swell in 3 dimensions

runbikeengr 04-18-2007 02:03 PM

floating tiles =mortar bed= paper+ wire lathe+ mortar+ tiles
 
1. float
2. i agree osb is ng for sub floors and will swell, absorb moisture,etc. but the general put that on and ther are walls on it, and i cannot pull it out easily. so have to put some floor covering on it now and trying to solve the problems now.
