 ooner or later, every owner of a historic house will confront the issue of failing paint. Paint failure is
caused by moisture problems, problems with preparation or application, or age.
Paint that is "alligatoring," or cracking in a pattern reminiscent of alligator skin, is indicative of an
excessive build-up of old paint. This build-up can obscure architectural detailing, particularly on interior elements such as mantles.
If paint is peeling away from the building down to bare wood, moisture is the most likely culprit. This
moisture may be caused by faulty caulking; problems with flashing at the roof line; leaky gutters or roofs;
or the presence of vegetation growing too close to your house. Resolve any moisture problems before you repaint.
Flaking top layers of paint usually indicate that there was inefficient paint preparation or application on
the last paint job. Preparation is a crucial step for a durable paint job and is labor intensive. Be sure that
you remove only the paint that is failing. Paint that is adhering is doing its job and does not need to be removed.
When removing the failing paint, do not allow disk sanders to be used on your historic house.
After the surface has been prepared, make sure it is dry before applying the paint. Try not to apply paint in
direct sunlight and be sure to allow drying time between coats.
There is no specific palette of "approved colors" in Charleston's historic district. Color approval is given on a
case-by-case basis by the BAR and covenant and easement holders. However, there are colors that are more appropriate
to particular architectural styles.
For more detailed paint specifications, contact HCF''s Manager of Easements and Technical Outreach, April Wood.
