Hi there,

I'm using porcelain tiles in the garden. It's quite a 'wet' garden due to run off from the neighbours land so I want to ensure that my tiles are properly primed (I've read that it's crucial with porcelain tiles).

I also read that you can use SBR and cement to make a slurry and just 'paint' it on to the tile.

Is the following SBR and cement suitable?

Everbuild SBR 503 - https://www.amazon.co.uk/dp/B001V9X..._dp_93Z3YHZGYEV7NJWDM4WY?_encoding=UTF8&psc=1

Blue Circle multi purpose cement -

And, if so, my next question is - what is the correct mix to make the slurry?

I've read 1 part SBR to 1 part water to 4 parts cement? Is that correct?

Other things I've read say not to use water and just use 1 part SBR to x parts cement?

Anyone got a definitive answer for this?

And... last question that I can't seem to find the answer to.... can I just slurry loads of tiles and leave them for another day before laying them? Or do I need to lay them when the slurry is still wet?? Or - after an hour? Or when the slurry is sticky or whatever?

Thanks for all your help :)

You need to lay while the slurry is still wet. Normally you dip one at a time and then lay immediately.
That's great info. Thanks. Couldn't find out (with quite a few Google searches) which way it was done. I wasn't sure if you could get a load of slabs, slurry them, leave them up against a wall, then do the bed and go and get them one at a time.

Sounds like the process is - do a slab's worth of bed, then slurry the slab, then stick it down (then levelling etc).

Thanks for the information. :)

...and clean everything properly before it goes off or you will regret it. Don't assume that, like ordinary mortar, you will knock off any blobs and spills, and get it off your tools...
