Don’t Mistake Cutting Corners for Cutting Edge
In this day and age of wonder products at all different price points, paint adhesion has come to be misunderstood.
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 (wood, drywall, etc.), is set squarely against the sometimes manipulated interpretation of paints and primers “in one”.
Works Much of the Time on Repaints
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 – proper prep will do. 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. Notable exceptions, such as painting over oil or lead, notwithstanding.
However, when the “no primer” idea 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 thing is nothing new. I have cans of Ben Moore Regal from 15 years ago which stated 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.
Paints and primers are best served in separate cans.
