Hello, Ive been told to use a mix containing Portland cement and not builders cement to lay Porcelain tiles for my patio. What cement product does that relate to? Many of them mention portland in one way or another.. Is there a particular brand of cement to use in the mix?
That's confusing as "builders' cement" is OPC - Ordinary Portland Cement. I wonder if this is a misunderstanding as cement is rarely ever used in it's own right and is one ingredient in a mix of others to provide different products such as mortar, render or concrete - all of which contain cement as a primary constituent but are totally different products - although each has been called 'cement' by the ill informed.
Thanks. I understand that cement will make up part of the mix along with sand. Im asking which cement would be best to use?
As, WillyEckerslike said an ordinary portland cement will do the job, but make sure to add a bit of SBR to the mix and also prime the tiles with SBR prior to laying. What will you be bedding the tiles onto?
Seems some confusion here (perhaps it’s me) Laying porcelain tiles outside, use a bagged / powdered tile adhesive suitable for exterior use - Mapei Keraquick being one brand You don’t lay porcelain tiles on a mortar mix, porcelain not being porous, won’t get a good bond Likewise, ‘most’ ready mixed tubs of tile adhesive are for ceramic tiles / small tiles and not large format or porcelain tiles Powdered tile adhesive is cement based and cures differently and is chemically different to ready mixed stuff So, good quality exterior powdered tile adhesive for this job, after suitable preparation of course

A dedicated tile adhesive would be an extremely expensive option if the sub grade happens to be a compacted hardcore, for example. Over a concrete base, then yes, use tile adhesive.
