Fill gaps & seal new shed to concrete slab. Want to be able to seal both outside and inside edge

Gaps up to 5mm in some places. In other places just want to seal around the edge of the shed to prevent water entry. One side of shed sits on a limestone retaining wall (where most of the gaps are). 3 sides of the shed sit on the concrete slab

I would recommend using our Selleys Seal Fix sealant for this application. It will bond well to all of the surfaces you have mentioned. If the grey is not a desirable colour then I would suggest using our Roof and Gutter Silicone sealant in translucent.
