The foaming equipment produces a highly concentrated borate-foam mixture that adheres well to most surfaces. Low runoff and increased wetting times encourages boron penetration of surfaces. The ability to force the foam under pressure between wood joints and into recesses allows treatment in some of the most inaccessible areas of the vessels. Boron wood preservatives offer a number of benefits to historic vessels in addition to their antifungal properties. Boron preservatives produce few visual or structural changes in wood.
Boron compounds are also effective flame retardants.
Our experience with boron treatments has proven to us that diffusion of this preservative can provide an increased level of protection to our vessels. Our question is not whether the treatment can be effective, but how best can the application be undertaken and maintained. We look forward to answering those questions in the near future and sharing the answers with you. Return to the Preservation Conference Schedule page .
