Weathering blending slabs

gadget88

So I replaced one slab with a new one as it was damaged the new one stood out. Managed to take one from the back garden instead which seems better when it’s wet it’s an exact match but when dry the weathering is slightly suggest but still a good match. Someone told me a new one would take 20 plus years to weather to same age so will my already weathered one same age blend in quicker? I am not keen to jet was more is fan of blending in with the open plan gardens.

Said with kindness, as people have said before, you need to give it at least a winter... it will take as long as it takes and no alternative short of replacing it all or jet washing the whole drive will make a new slab blend in immediately - asking again won't change the answer
