In 1995, the founder of Preservation Solutions, was approached by the head archaeologist for the Maine State Museum with a challenge to develop a better method of stabilizing and preserving waterlogged wood. Using his background in leather and wood treatment preservation, and 2 years of testing a formula for waterlogged wood conservation was conceived. Thus, SP-11 Waterlogged Wood Treatment was developed.
SP-11 has been used and tested on waterlogged wooden artifacts for more than 25 years with highly successful results.
