Hi everyone! I’m planning to build a 20mm outdoor porcelain tile patio in my garden.

I know I need to mix a semi-dry mortar bed with cement (using slurry primer on the tiles), but I’m really confused about what sand to buy here in Ireland.

At Chadwicks, they only seem to list Plastering Sand, Mortar Sand, and Paving Sand. There is no standard "Sharp Sand" on the list.

Which one of these is the correct gritty equivalent to use for a porcelain mortar bed so it doesn't shrink or hold water? Or is there another name I should be asking for at the yard?

Thanks a mill for any advice!
