Have just erected a yardmaster tin shed. I need to put a 'sealant' around the edge of the steel frame base where it sits on the concrete foundation, to prevent water traveling in under the frame.
I normally get things like sealants from Wickes or Screwfix, but there are a bewildering array of different sealants available. Would anyone recommend which would be the one to use in this particular application please?

Silicon if you dont mind the cost.
Mastic if you do.
Look to Aldi or Lidl, silicon for under a quid a cartridge, I always stock up when they have it.

Its not the shed that matters, what matters is whether the concrete its mounted on gets standing water on it. If it does, it will get in under the bottom of the walls and what is inside the shed will get wet.
He's not saying that the shed itself leaks, just that water can get between the concrete floor and the walls.
but it look the same.
Clear silicone caulk should work fine.

Guttering? Just be awae that any sealant onto concrete will eventually lift and llow the water to flow underneath it. If you concrete slab is bigger than your shed, it is inevitable.

Nope, silicone wont. Mastic wont either.
Wrong, as always.
I have not seen silicone resist moisture and steel will rust under silicone.

=================================== I would suggest a strong mortar weathering fillet about 2 or 3 inches high, depending on how much space there is on the slab. Leave a small gap at the top between fillet and shed wall and cover the gap with a basic 'frame sealant' from Wickes when the fillet is dry. Be prepared to repair every 20 years.
