Questions about polymerizing wood preservation. Listed as a non-toxic approach.

Thanks to Jay C. White Cloud. I am now aware of preserving wood with minerals [Iron Sulfate] and Borates.

There are two other materials that were not covered in his post that I want to ask about.

Seal-Once Eco-friendly Wood Polymerization.

Seal-Once is a penetrating complex co-polymer. Seal-Once products first appeared on the market in 2005.

"By incorporating sub-micron particles a unique lattice work is formed allowing the product to sink deep below the surface. As it cures it forms an interior film that prevents water from infiltrating through the surface. The same effect occurs in concrete and masonry with the forming of a flexible polymer film. Seal-Once uses a blend of polymers designed to move with a wood’s natural expansion/contraction cycles. Typical water seal products form a waxy film on the surface that will wear off in a short amount of time especially on wood decks. The Seal-Once effective finish life is 6 years on horizontal surfaces, and up to 10 years on vertical surfaces. Approved safe for use over fresh and saltwater. When Seal-Once dries on a substrate, it does not leach out or become hydrolytically unstable, however it may be removed by wearing the substrate away or by application of strong oxidizers. Seal-Once is approved by the State of N.H. Department of Environmental Services (DES) for use over water." Toxicity over water: http://www.seal-once.com/pdfs/Seal-Once_Toxicity_Summary.pdf
"Clear Seal-Once is UV stable which means it will not degrade in UV radiation, but clear Seal-Once does not provide UV protection. Without adding a tint, Seal-Once is a penetrating sealer which allows the exposed surface to age naturally, all wood surfaces will turn to a patina gray."

TriCoPolymer Agralife Lumber-Seal 1 gal. Clear Satin Wood Sealer
MSDS, General info and toxicology: https://cdn.shopify.com/s/files/1/0123/2282/files/lumber-seal-product-info.pdf
"Waterproof, stabilize and maintain original color with VOC free and nontoxic eco coating. The films unique barrier action seals out moisture and contaminants, protects against mold, decay, pests and weathering. Lumber seal also stabilizes the coated wood by allowing any excessive moisture to pass out of the wood gradually through the film. Lumber seal dries clear and maintains the woods finish for years to come."


MY PROJECT
I am building an 8ftx8ft chicken coop. Raised from the ground on concrete pyramid style posts every 4 feet in sides and one in the center. Frame is pine. Sides are plywood. Roof is plywood with cedar roof shingles.

I have ordered some Iron Sulfate and some Wine Tannins. I am planning to soak pine and cedar roof shingles in tannins, wait till dry, then apply the Iron Sulfate. This will then react with the tannins to form Iron tannate turning the wood silvery grey and preserving it.

Unfortunately, I already used seal once on the base. And floor joists. I also made the mistake of building the frame first and then applying the seal once so the insides of the joints are not treated. Just the outsides. Sadly, I read Jay C. White Cloud's post about minerals and Borates after I completed that project. In hindsight probably would have used Borates.
