New Resins for Formulating Interior, Odorless, Solventborne, Stain-Blocking Primers
Since their introduction to the U.S. market in 1997, odorless stain-blocking primers have gained a well-deserved reputation. They are appreciated for their unique combination of highly effective stain blocking, traditionally associated with solventborne products, as well as with the comfort of application and low odor commonly associated with waterborne products. A good primer has to be compatible with a wide variety of substrates that may be encountered in an interior situation, such as drywall, cement, concrete, plaster and spackling, wood, paneling, old paint, metals, fiberboard, etc. Very frequently, particularly in renovation work, the surfaces encountered will be covered with a variety of stains, such as water-soluble types from water leaks, smoke, nicotine, inks, etc., as well as solvent-soluble stains such as tar, tannin and others.
