porcelain for patio - DIY

bumblebee22

I m planning DIY job for porcelain tiles on my patio. I have done DIY indoor tiling but first time outdoor. I would have used flexi adhesive likes of technik rapid set flexible but patio is not level and in need to level it up with minimum 3.5inches. I m planning to use sand with portland cement 1:4 ratio.

Problem I have is to find primer for my porcelain tiles available in Ireland but I can not find anything. My local builder gave me Evo-Stik Primer 918 but I think its wrong product for this job.

I also watched couple of videos on YouTube about primer and not to prime, I would love to hear your opening before I end up in horror situation :)

diy'd this a few weeks ago. like you said, there is pretty much no primer around - I used sbr and cement to back butter the tiles. laid the first few tiles mixing manually and it was a pain so get yourself a mixer if you can(or rent). the tricky bit was to get the right mix texture. i went with 4 sand and 1 cement. luckily for me, i didn't have to cut any tiles .... best of luck

i have used sbr with cement as well. i have to do rest of the area and i m getting mixer for this. did you use any plasticizer to make mix workable?
