Keith has provided this picture of the new tiles in The Square looking decidedly grubby. As he says, the dirt is worse in places than his photo suggests.
But we remember a similar situation when the ‘first phase’ of floor tiles was laid in Grace Reynolds Walk. We recall being told that the tile adhesive/cement had to be allowed to dry before the tiles could be grouted and sealed. So we guess that the grubbiness is only temporary.
Maybe it would help if there were a sign nearby to confirm this?
