DIY Related: Shuttering ply

[DearMe]

Hi
My first post and a question about whether I can use 18mm shuttering ply to overboard the original floorboards before laying 300x600mm porcelain tiles. I would be grateful too for any suggestions on which adhesive and grout too. I would be grateful for any suggestions at all really. Thanks.

Hi DearMe, would you be good enough to say hi to people and tell us a bit about yourself in the New Members section of the forums. Ta!

In answer to your question, no, shuttering ply is not suitable for overboarding. It needs to be WBP ply or marine ply. WBP is cheaper.

Use a flexible adhesive such as BAL SPF (or rapidset) or Mapei flexible adhesives if you can get them. Ardex 7001 is excellent also. You will need to use a flexible grout too. Ultracolor plus is my prefered choice at present, though it is not as easy to use as some others that are available.

Hi Dearme

welcome to the forum.



As for the adhesive - the worlds your oyster. Obviously you will be using bagged with porcelbond and flexible properties. I have used bal rapidset and the weber equivalent. Both as good but the weber was a third the price as CTD had a special offer on - so look for one of those

wait for more replies from the boys who know

(edited - I thought I was on safe ground here as I asked this exact question of a 'pro' tiler before I helped my brother. No harm done I haven't started yet. Now what was it he said about pva? )

Shuttering ply..OSB...is a big NO NO to tile to....it is not a stable enough product to tile too...
You will need WBP ply or some sort of backer/aqua board..

Hello and welcome

[DearMe]

Thanks for the help.
The good wood has been ordered and is now in my garage waiting for me to do something with it.

Oh well, I may get a kitchen by Christmas.
