The client had been looking for yellow and reds that corresponded more faithfully with the original Edwardian geometric tiles. I proposed Winckelmans 'geometric' tiles because they are fully vitrified and thus frost resistant—the colours matched, if one takes into account that the inner Porch ones have acquired patina and it’s darker. I proposed to use a 10x10cms format to improve proportion relationship; I felt the 15x15 cms were too large to follow the existing 7.6x7.6 cms tile. The Winckelmans's tiles are vitrified, waterproof and frost resistance. The original concrete base was primed, a layer of levelling compound was poured and troweled to improve tile adherence and reduce porosity. Waterproof and frost resistance adhesive and grout were used to avoid the recurrence of frost shattering. Finally, 1mm tile spacers were used to be more faithful to the virtual grout less lines of the Edwardian tiles.
