Laying porcelain tiles in the garden

ando

Hey,

I'm trying to lay down a few porcelain tiles in my back garden. I've dug the area, leveled it, bought the gravel.. I want pre-made sand/cement mix so I just have to add water, I think Woodies have this (I presume an adhesive is the wrong thing for outdoor application?), but most of all I'm having great difficulty getting a primer.

Can anyone suggest where to buy a tile primer, I believe this helps with the tile sticking to the wet cement.

I believe an SBR primer is what you need, something like Sika SBR (which I have used and is excellent), there are other brands available. Generally mixed with cement to a slurry and brushed onto the required area, but be aware it does go off very quickly, so you'll want to have your work well planned and know what your at- if you get it on the face of the tiles you'll never get it off if it's allowed to dry.

SBR seemed to be what was recommended for this alright, but it's not a Woodies product; try a builder's providers. It's normally watered down 50/50 for tiling and applied and let dry until it becomes tacky and then the tile stuck down.

Most of all, get your adhesive base right though - back-butter the tiles properly and know what tiling trowel (large gap) you need.

Reading the SBR tech sheet they do say to grout and back butter, but I have seen a fair few tilers who will just slurry and then straight onto the bed.

e.g. tidybricks on youtube only uses a slurry primer and he does great work.
