Background: 20 year old house with original Bilco classic bulkhead door (see image below). Water was leaking in around the metal Sill and rotted the top step and stringer. I removed all the old caulk around the perimeter which was in bad shape and replaced it with a heavy hand of Sika Polyurethane Construction Sealant per the Bilco caulking instructions. Additionally, I purchased and installed the Bilco weather stripping kit for additional protection.
Problem We got some rain recently and water is still penetrating what appears to be under the recently caulked sill (see pictures below). Am I missing something? Is it saturating the concrete and getting under the Sill?
