Lime mortar 12.5kg (N16)

This is lime and dry sand mix that was swept between the bricks/London socks of my patio then watered in. This is the leftover. Stunning visual result and kills everything - weeds etc. tho not sure about that with biodiversity issues UK is facing. Anyway, it is more usually used for traditional/heritage brickwork or can be mixed with cement. About 12.5 kg
