| Good
paint performance depends on good adhesion, and paint adheres
best to surfaces that are clean and sound. That’s why contractors
make sure the surface is in this condition before they start.
Taking shortcuts on surface prep can cause
even the highest quality paints to fail prematurely. In fact,
according to experts at The Rohm and Haas Paint Quality Institute,
inadequate surface preparation is the single greatest cause
of premature exterior paint failures.
Thus, just as a builder needs a solid foundation
to construct a house that lasts, so too must a painting contractor
start with a sound surface. It is the first step to a durable,
long-lasting exterior paint job.
Benefits of a Properly Prepared Surface
- Better Adhesion - the paint is less
likely to blister, flake or peel
- Better Uniformity - the paint has a more
consistent color and sheen or gloss
- Better hiding - no show-through from the
surface that is being painted
- Increased Mildew Resistance - the paint
won’t be marred by unsightly black or brown fungal growth
- Increased Corrosion Resistance - when
painting metal, results in a longer-lasting job because of
better protection against rusting
