It will buffer and naturally it has the ability penetrate and de acidify paper to a certain extent, however It is not as effective as dipping the poster in a CaCO3 bath. Great product for do it yourself home remedy. long tearm No!! But nothing stops you from re buffer after a few years. Best, Dario.

Hence "Buffer", there is a big difference from "impregnate" when soaking the poster in a  deacidifying bath the poster will be completely soak through and impregnated with Ca CO3. Dario.

I apply it liberally to both the front and back of each poster. Although it looks 'wet' when you apply it, the carrier solvent is a non-aqueous one which evaporates very quickly leaving the magnesium buffer behind; the paper is not actually moistened. I have had NO problems with wrinkling, curling, discoloration, or ink running. Now, how well it actually works to deacidify a poster is another question, probably nowhere near as well as a deacidifying bath but better than nothing. Also the stuff's not cheap, and you go through it fast with larger pieces. Randy Are you talking about using a product like Bookkeepers spray to deacidify the poster? Has anyone used this spray? And if so, how did the poster react to the spray? Rolling, wrinkles?
