I believe when one looks into purchasing a product like PETRI-WOOD (THE PRODUCT ABOVE IN QUESTION) for a specific project they should look at all the facts and research on that product and not listen to people who have not researched or used said product as you will find out below. So when looking into new alternative wood products that are not a plain water sealer which needs to be applied every 2 to 3 years, but wood penetrants one should look at the science and the facts. The product in question is petri-wood which in fact is a product when sprayed on only one side penetrates completely through the wood media (heart wood) all the way to the other side. It is currently being used on more than 11 miles of platforms for the Chicago Transit Authority and Ft. Lewis Military Installations cement buildings. Just two of the many projects this product is currently be used on.
It was tested by Iowa St. U & Mississippi St U for the USDA FEDERAL BIO-PREFERRED PROGRAM (which none of the products being compared too above are involved in except PETRI-WOOD) signed by the president and Congress which allows only products that are 100% natural and have been tested and proven as good as if not better than there chemical counterparts. As noted above by another comment that the company does not post there MSDS sheet on there web site is false they in fact do along with a 90 page University study. So in order to make a good buying decision sometimes one must research for themselves. The product in question petri-wood in fact is either being used, brokered or endorsed by the following :

Dr. George Jenkins, noted canadian wood scientist U. of New Brunswich Can. qoutes "The science of this invention triggers the early stages of petrification of wood" C. Wayne smith heads up Texas A & M Archaeological Preservation Research Lab. qoutes "it is the SILVER BULLET the industry has been waiting for" scott miller application Engineer for Dow Corning Corp. agrees with Smith. Dr. Robert Adams Baylor U. support the claims as noted in his 1992 publications. The above mentioned product has obviously got its scientific backing and how it works is the product penetration of the hydroxyl group molecular structure where upon entrance it becomes a water scavenger (unlike water based products, this is a solvent 100% all natural) completely eliminating any free or bound water in the wood. The hydrogen tail of the molecule is then collapsed and no further moisture can enter the wood cellular structure, thus leaving the media 100% dimensionally stable, an objective not obtainable with kiln dry methods. "The absence of moisture is the absence of issues" no warping, bending, cupping, splitting, rot or disease. After researching this product i believe you will find no other product on the market including the ones mentioned above that has this many endorsements nor does what this product does. Petri-Wood even puts an additional 25 year warranty when applied to utility poles already in use. Before you use any product you must first research the facts not people who claim to know a product or web site when in fact all this info. is clearly on there site including the MSDS sheet. See for yourself.
