"Hello, You will need elasticated/flexible floor tile adhesive for floor tiles, ideally rapid-set if possible. For porcelain tiles specifically, do seek adhesives which are made to bond with porcelain – using terms like; “porcel-bond” or “porcel-plus”. Many would recommend Mapei rapid-set adhesive for porcelain specifically, as it ticks all these boxes. Generally, 20kg bag equates to 5m squared. Additionally, for grouting, you should seek grouting with similar properties – I believe Unibond does a version that may fit the bill. Be aware of the grouting colour choices before purchase, to ensure you have a suitable match for your tiles.

Microban typically offers a range of different grouting colours. Before laying the tiles with adhesive, the floorboards must be secured correctly. Ply boarding must be screwed in (with a minimum of 9mm thickness) for every 150mm in each direction – this ensures that British legal standards are being met. Afterwards, the boarding can be sealed with PVA. Following this, the adhesive can begin to be applied, ready for the laying the tiles and for grouting afterwards."
