With the tiled floor in the hallway laid, it will need protection for the remainder of the build.
So after brushing and hoovering the tiles to take up any debris, cardboard packaging is used with any metal staples removed to completely cover the tiled areas. The cardboard sections are taped up with duct tape. Then hardboard is used smooth side down to create a hard wearing surface.
The hardboard is used this way round to avoid creating a slippery surface if it gets wet. The carboard will stop any sharp gritty bits from marking the tiles. This will now stay down until we need to put the skirting down just before the house is finished.
