Yes, there is a reason - you'll most likely be cutting it with a

I was going to use a downcut blade and I assumed the sink lip would be wide
enough to hide any chipped laminate.

It's perfectly doable, but I think it complicates things
unnecessarily - it's mych nice cutting worktop from underneath
with an upcut blade.


No sorry, the tiles are on the wall behind the worktop. So when to seal with
silicone before or after I tile?

I'm sorry, I still don't understand. Is the sink butting up
against the wall tiles? Otherwise why would it make any
difference whether you seal before or after tiling?
