Pedro,

Id go for a good quality silcone sealant, its important that is has high
elasticity as the metal will expand a great deal more than the conrete with
temperture. If go for a heavy duty exterior silcone sealant. I think some
gutter sealants may fit the bill. Must be highly elastic.

Hi All,

I have just erected (after much trouble) one of those yardmaster metal
sheds. What a nightmare.....

Anyway its up now and I want to seal around the base on the inside. It
leaks quite a lot from the grooves in the concrete.....

Any ideas?

Cheers
