Don’t Mistake Cutting Corners for Cutting Edge
My June 2013 “From the Field” column in APC magazine discussed the concept of paint adhesion – a topic that is rather confused and misunderstood in this day and age of paint products. On the one hand, the “old school” approach to using a 3 coat system on new surfaces, which involved primer and two coats of finish, regardless of substrate, is set squarely against the sometimes manipulated interpretation of paints and primers “in one”.
To set the record straight, I am amongst the painters who believe that in the majority of repaint situations, whether walls or trim or ceilings or all of the above, in most situations it is not necessary to use primer to achieve paint adhesion when painting over existing paint. And in most situations, two coats of paint will do just fine, when painting over paint. I don’t think many of us are arguing that point.
However, when that concept gets stretched to apply to ALL painting situations, that is where some of us throw a flag. It is no secret that this whole paint and primer in one idea is nothing new. I have cans of Ben Moore Regal from 15 years ago that suggested that the paint could be used as a primer on small scale drywall patches and skims. In recent years, though, this idea has been interpreted and twisted to the questionable conclusion that primer is no longer needed at all.
If this were the case, I can assure you that no paint manufacturer would waste time and energy producing primers, when pretty much all of them have paints that fit the basic “paint and primer in one” criteria. Enough of us have seen paints fail as primers, and primers fail as paints, to know that they really don’t belong in the same can. But, there are still plenty of painters and homeowners who will go merrily along pushing that envelope and compromising paint adhesion along the way.
Anyways, to read more of the particulars about why primer and paint are still better off in separate cans, please CLICK RIGHT HERE to read my article in American Painting Contractor magazine, June 2013.
Please share any stories you may have, better or worse, about the whole experience of “paint adhesion” as it relates to primer, paint, and primer/paints in one.
