I'm repairing the stairs of a deck structure, replacing dry-rot stringers with new ones. The stringers rest on top of a cement pool deck. The pool deck is sloped towards the stairs, so I expect rain water to come towards the stringers.
Is there a good technique to water proof the new stringers? I was thinking using Redguard type of waterproofing but I read that this could make things worst as moisture could potentially be kept in.
The stairs are about 20 feet wide, so I have about a dozen stringers to deal with.
This is what some of the stringers look like after 16 years.
