There is no primer available anywhere, not through speciality suppliers or retail outlets or any other, that functions as an adhesion promoting primer, a porosity sealing primer, a tannin-blocking primer, an acidity neutralizing primer and a sanding-primer, (as well as resisting long-term coating failure) all-in-one thus the new brand name MultiwoodPrime.

Why aren't other primers effective?

The old, but still currently marketed primer formulations have not kept up with the changes effected by governmental legislation which forced topcoat manufacturers to remove key ingredients because of enviromental issues. No primer, old or new was ever able to fully impregnate the porosity of old, weathered wood and new sound wood. The quality of lumber being sold today is not the same as it was when the orginal primers were formulated.

Historically, a simple lead carbonated oil-base primer "White Lead" worked well on slow-growing dense old growth wood because the lead carbonate also functioned as a mild, effective fungicide. We all know government regulators removed the lead from all paint, but that wasn't all that changed. The lumber industry developed fast-growing trees and their wood was much more porous than the slow growing types. Lastly, latex paint replaced oil-based paint, with latex paint manufacturers claiming their latex product could be used directly on wood as a primer, as well as a topcoat. After these three changes took place, consumers found their wood rotted more easily, paint did not prevent rot, and when rot developed under the layer of paint, the paint separated from the wood.

MultiWoodPrime, as opposed to other primers on the market, provides the ingredients needed and/or missing in common primers which fail to keep paint stuck to the wood after one or a few years, In this way MultWoodPrime compensates for today's highly porous wood.
