Brother-in-law has had to remove the screed from the garage that he built for me because it has delaminated/blown. He thinks that this happened because water crept under the screed at the garage door, i.e. where the edge of the screed is exposed to the elements. He is applying SBR between the new screed and the base but wants to know if/how he can seal the exposed edge such that water does not penetrate again.
Thanks
