Update on Old time waterproofing

We're lucky enough to have all of the documents of when this house was built, including the contract, blueprints for the house and landscaping, and the original price list.

We need to have these documents these preserved before they deteriorate more. Suggestions?

Anyways here's some information about the funny, bentonite like coating that I've talked about before. The contract gives insight.


BASEMENT WALLS

Recreation room and office in basement concrete block walls shall be coated with 2 coats of "Cementico", color as desired.


Some basic searching on Google shows that it's calcimine paint, translation: whitewash. I would appreciate more information if anyone can aid.
