OSB.Any good ?

[Del W]

Was talking to a guy yesterday about,Oreinted Strand Board,he said because of the resin used to bind it together,it has waterproof/water resistant qualitys.? Asking because a customer of mine does not want to overboard his t&g moisture resistant chipboard,which is going to be screwed to solid timber joists,with cement board because of price.He also wont remove chipboard and replace with ply. Sounds to me that OSB is posh chipboard. Thoughts ?

i believe its cheaper the chip board , and personally i would not tile on it , its a bit like sterling board i think ,

hope that helps

its great but tell him he will need to use bluetac if he is going to tile it

Can't you use 6mm hardie board over the top, glued and screwed.

Another tight wad! Won't spend a few extra quid now but will no doubt moan when the tiling lasts a few weeks!

i suggest you walk away from this one, its a recipe for disaster, no one likes to walk away from work , but some times needs must im afraid

If you do a mix of pva wall paper past and saw dust that will save on all the expensive adhesives and you can tell him to make further savings he can fit them his self ! In fact if he is that tight why have tiles just through some saw dust on the floor and be done with it. :mad2:

OSB is not waterproof as far as I am aware......

I made a wendy house for the kids last year and used osb for the roof (it was then felted and bitumen tiled) a couple of offcuts were left outside in the elements and have soaked water up in a chipboard/weetabix style and fell to bits. I know there are different grades and types of OSB but none of it is suitable for our type of tiling. As deano says pva, wallpaper paste and sawdust for adhesive weetabix and milk left to dry for overboarding.

OSB and sterling board are the same thing, and I dont know of any company that recommends tiling to it.

Hi Del W

I know exactly what I would do - Inform the client why he is penny wise/pound foolish and then inform him of the way you are going to prep it and tile it and if he/she will not / cannot pay the true costs, I would walk.
