Priming plywood??

[Rascal]

Hi all,

I'll be tiling a bathroom floor tomorrow, there is already ply down so plan on tiling straight on this. The customer has gone and bought some tops 'trade' adhesive even though I told them I would get the adhesive! Is there any need to prime the ply, it has had carpet on it before I think. Also anyone used tops addy before, i've always used bal in the past?

How thick is the ply and what is it laid on to..? and how is it fixed.?

It's screwed onto floor boards I think -12mm I hope, I get a bit complacent sometimes just asuming but i'm pretty sur, i'm going to make sure it's well fixed first. the whole bathroom suite is sitting on top of it, but I can take one piece up to check.

as for the addy! it's fine,i used it for years when i used topps and actually preferred it to bal it does tend to go off quick so be careful mixing up your first batch

What is a trade adhesive.
Is it a cement based flexible product and what size tles are you using.

Have to call you cheeky!

just measure the depth at the door

Just look in the doorway.. you will see the edge there....

Now if that ply has been down a while under a carpet, it might be contaminated now with old water/muck residue when the carpet got wet from showers etc..

It might be wise to use a 6mm cement board over the top..

'Trade' is just a word they stick on products to make it sound professional! 30 x 30 tiles, its a rapid set flexible.

Cheeky??

The ply is sound...looks like new. So what about a primer...no harm in a coat of bal sbr I take it...how long till you can tile on this?? All other bal primers are 30 mins but cant find info on SBR??
