Has anyone used this on porcelain paving slabs?

It works perfectly fine as long as the joint is 5mm or larger. Ensure the paving is damp so the pointing doesn’t stick to the surface

I bought this and used it on my path which has now set, but need more as it's not high enough and gaps. Can I put more ontop of set Sika??

I did this and it was fine, i just made sure it was well compressed, it has not separated so far after 2 years. It generally does seem to attract moss which nobody has mentioned.

Can this be used to repoint already pointed Indian sand stone where grouting has come off ..?

You need to rake out all the existing pointing before repointing and push the Sika Fastfix into the open joints with a pointing trowel.

how many bags will I need to do 120 slabs?

Everything depends on the width and depth of your joints,each box is supposed to do 20 sq metres but I found that I had to buy six bikes to do my 60 sq metres. Expensive but I think worth it for ease of use and hopefully durability.
